How Much Propane Does A Hot Water Heater Use

How Much Propane Does A 40 Gallon Water Heater Use (Explained)

The amount of propane required by a hot water heater will vary depending on a variety of factors, including the age of the water heater and the amount of hot water required in the home. A 40-gallon hot water heater is a common tank size since it can accommodate the demands of the ordinary family, which may accommodate up to two to three persons on average. The question is, how much propane is consumed by a 40-gallon hot water heater. The water heater in a normal family of two to three persons with a 40-gallon water heater will use around 1.5 gallons of propane per day, or 200 to 300 hundred gallons of propane per year, according to the Environmental Protection Agency.

As previously stated, the quantity of propane that a forty-gallon water heater really consumes will be determined by a variety of factors that may either raise or decrease the amount of gas that your heater consumes.

Factors That Affect How Much Propane Is Used

Unfortunately, the quantity of propane consumed by your forty-gallon water heater may differ from the estimate shown above. This is due to a variety of factors. The following are two of the most important elements that will influence the amount of propane used by your water heater.

How Old Is the Water Heater?

Water heaters have a rather long life expectancy, ranging from 8 to 12 years on average. As a result, selecting the right water heater and energy source is quite crucial. Your water heater will be one of the busiest components in your home, thanks to the use of showers, washing machines, dishwashers, and other hot water-using equipment in your home. A result of the fact that water heaters play such an important function in the home, they are intended to be as energy efficient as possible. While this is typical for everything in your home, as your water heater ages, it will become less and less efficient, requiring you to consume more energy and, consequently, more propane to maintain the same level of efficiency.

The silt, on the other hand, will tend to accumulate and have a detrimental influence on the water heater’s capacity to heat the water in an energy-efficient manner.

How Much Is the Hot Water Being Used?

If a forty-gallon water heater is trying to satisfy the demands of a big family, it will consume more propane than it should be able to provide. A forty-gallon water heater should be sufficient for a three-person household’s water heating requirements. Even so, if you have a large number of guests over on a regular basis and your family is very active, your water heater will require extra gas to keep up with the demand. Even if you don’t have a lot of visitors, there are a variety of additional factors that might cause your water heater to consume more than two to three hundred gallons of propane every year.

How To Reduce Energy Consumption/Propane Use

It may be quite useful for homeowners to know how much propane their water heater consumes in order to make educated decisions regarding their energy use. No matter if you are attempting to be environmentally conscious, wishing to lower your utility bills, maintaining a tight budget, or simply wishing to have hot water for longer periods of time, you will discover that there are numerous ways to reduce energy consumption and get the most out of both your propane and your water heater. Listed below are a few suggestions for lowering the amount of gas your water heater consumes.

Power Consumption by a Recreational Vehicle Fridge

Old Water Heater- Replace It

In addition to what has already been said, an old water heater does not use propane as effectively as it did when it was first installed. Your best choice if your water heater is getting on in years and you want to minimize the amount of propane you use to meet your household’s hot water demands is to invest in a new unit before the present one ceases to perform properly. You may find it depressing to spend that amount of money when you are attempting to minimize costs rather than raise them.

Obtaining a new water heater and selecting the most appropriate model has also been made much simpler, allowing you to maintain more control over your gas use.

‘In order to solve this issue and provide customers with the ability to make more accurate brand comparisons, the Department of Energy replaced the prior energy efficiency rating with what is now known as the Uniform Energy Factor, or UFE.’ The first-hour rating of a water heater is one of the most essential pieces of information that a UFE rating can provide to homeowners.

Newer versions also have the advantage of having greater tank insulation quality, which is an added perk.

Heater Still Has Some Years Left In It?

You could consider investing in a new water heater if you believe your current water heater has several more good years of service remaining in it.

As an alternative, there are a few things you can do to assist increase the efficiency of your water heater while also lowering the amount of propane it consumes. For example, silt build-up that develops over time may be avoided with the proper measures.

1.Clear Out Sediment

As previously stated, a buildup of silt can have an adverse effect on the functioning of your water heater. Consequently, depending on your water supply, it is advised that you cleanse your water heater one to two times each year at the very least. This is due to the fact that when water is heated, minerals such as calcium and magnesium dissolve and form microscopic particles of silt. Well water contains a high concentration of these minerals and must be washed out twice a year in order to prevent the heater from malfunctioning.

2.Keep Up On Maintenance

It is critical to keep up with routine maintenance. Although a water heater can be expensive to replace, by ensuring that all of its operating parts are in proper working condition, you can ensure that everything runs smoothly and effectively. The greater the efficiency with which the parts operate, the less propane is used to heat water. If you are unaware of what maintenance comprises, it is always advised that you refer to the owner’s handbook for guidance on how to proceed. You may also hire a plumber to come in and inspect it, particularly if you believe it is not operating as effectively as it should.

3. Insulate Your 40 Gallon Water Heater

Adding insulation to your forty-gallon water heater can help it hold heat longer, allowing it to operate more efficiently. Recent developments in water heater design have addressed the issue of standing heat loss, which has been previously discussed (the heat it loses just from being idle in the water heater tank). Using an insulating water heater jacket, regardless of whether your water heater is a recent model or not, you can always improve its capacity to retain heat.

4.Limit the Amount of Hot Water Being Used

When it comes to lowering the amount of gas that your water heater consumes, this one may seem like a no-brainer to you. In the event that you are not using the hot water as frequently, you will not require as much propane to refuel the tank with hot water, which will save you money. The smallest of modifications, like as using cold water in your washing machine and only washing full loads, as well as ensuring that your dishwasher is completely full before beginning to wash dishes, may make a significant impact.

5.Update Appliances

For people who have out-of-date appliances that require hot water, updating such out-of-date items is a wonderful method to lower the amount of propane your water heater consumes. In today’s environmentally conscious environment, where manufacturers are vying to give consumers with energy-saving items, you will be able to locate products that will save you money in the long run as a result of their efficiency in terms of energy usage.

Purchasing and upgrading appliances that consume a lot of energy, like to purchasing a new water heater, will cut your propane costs and allow you to return the money you spent later on via savings. You may also be interested in:Can I Store Propane Tanks in a Shed (FACTS You Should Know)

Final Thoughts…

As you can see, there are a variety of factors that might influence the amount of propane used by a forty-gallon water heater. In the case of a forty-gallon propane tank, if you discover that you are using more than two to three hundred gallons of propane every year, it may be time to give the device a once-over with maintenance care. Because propane costs are continuously shifting, preserving your propane and saving a few pennies may make a significant impact in your bottom line. References

How Much Propane Does A Tankless Water Heater Use? (+ Calculator)

Propane tankless water heaters are the most energy-intensive of all water heaters (still about 41 percent more economic than conventional tank water heaters). There isn’t a propane-powered device on the market that consumes more propane than these on-demand heaters. What is the actual amount of propane that a tankless water heater consumes? The amount of propane used (as well as the accompanying financial cost) is determined by three major factors. These are the ones:

  1. Size of a tankless propane tank in cubic feet. A tankless heater that uses 11 GPM (199,000 BTU) propane will consume significantly more propane than a tankless heater that uses 7 GPM (75,000 BTU). The production of hot water. A propane tankless water heater that runs for one hour per day will consume more energy than a similar one that runs for twenty minutes per day. Efficiencies in energy use. On-demand hot water heaters powered by propane are often quite efficient. The efficiency of propane combustion (as measured by the EF factor) begins at 80 percent. The most energy-efficient propane tankless heaters have an energy efficiency of up to 99 percent (0.99 EF)
  2. These systems utilize the least amount of propane while producing the most hot water.

We can determine how much propane is consumed by a tankless propane heater based on these three criteria.

As an example of propane consumption, consider the following summary (we assume 100 percent output, 100 percent energy efficiency, and a $2.41 average national price per gallon of propane): a.

  • The smallest 53,000 BTU unit (at the low end) consumes 0.58 gallons of propane every hour of operation. That equates to a $1.40/hour operating cost. The largest 199,000 BTU unit (high end) consumes 2.18 gallons of propane per hour of operation. That equates to a $5.25/hour operating cost.

On Energy Star labeling, the standardized annual propane tankless heater use is specified at 200 gallons, which is consistent with industry standards. That works out to around $482 each year. When it comes to the real cost of operating a propane tankless water heater on an annual basis, the variety is enormous. According to our estimations, the following are the low-end and high-end expenses for a typical project:

  • Low-end (a 53,000 BTU unit running 20 minutes per day with a 0.99 EF): 71.22 gallons per year. That works out to around $171.64 each year. 992.80 gallons per year for a high-end unit (199,000 BTU unit, 60 min/day, 0.80 EF). That works out to around $2,392.65 each year.

What does it tell us about the amount of propane our personal propane tankless water heater consumes, you might be thinking. Due to the fact that some families have tiny units, while others have larger units, and some households use these propane on-demand water heaters for one hour per day while others use them for just 20 minutes per day, the reasons for this are several. We’ve developed a Tankless Propane Usage Calculator to assist everyone in accurately estimating the propane use of their individual tankless device.

The calculator may be found lower down the page.

This will provide you with an approximate estimate of how many gallons of propane your tankless propane system consumes each year.

How To Calculate Propane Usage For Tankless Water Heater?

Water is renowned for being difficult to heat. This is owing to the high specific heat (4.19 kJ/kg°C) of the material. Propane tankless heaters can heat more than 10 GPM of water in less than 15 seconds, making them ideal for commercial applications. To do this, a tremendous quantity of energy is required, and all of that energy comes from the combustion of propane. We need to know the energy content of propane in order to compute how much propane is consumed by these on-demand heaters in order to heat up water on demand.

To put it another way, burning a gallon of propane creates 91,452 BTUs (at 100 percent efficiency).

If we look at Rinnai units (Rinnai manufactures the best propane tankless heaters; you can learn more about them here), we can see that they offer units ranging from 5.3 GPM (these units produce 53,000 BTUheating output at 100 percent capacity) to 11 GPM (these units produce 53,000 BTUheating output at 100 percent capacity) (these units produce199,000 BTUheating output at 100 percent capacity).

  • That’s a flow rate of 11 GPM.
  • The digit 199 in the model number indicates that this heater is propane tankless.
  • We already know that a propane-fueled unit of this size will generate 199,000 BTU of heating output.
  • With this information, we can determine how much propane is consumed per hour by a large tankless propane heater.
  • According to this calculation, the largest propane tankless water heater will consume 2.18 gallons of propane per hour (at 100 percent output).
  • This is how we go about it: 2.18 gallon per hour (Propane use) x $2.41/gall (Propane cost) = $5.25 per hour (Running Cost).
  • To be sure, we must take into consideration the fact that propane does not burn at a 100 percent efficiency.

All of this may appear to be a bit complicated at this point. That’s why we made the process as simple as possible by including an easy-to-use propane use calculator as well as a summary table below the calculator. You can use it without restriction here:

Tankless Propane Water Heater Usage Calculator

To figure out how much propane a tankless propane heater is expected to consume in a year, you just enter the unit’s size (in BTUs), its energy efficiency (which is typically around 95 percent), and the number of hours per day you expect to use the unit at full capacity. This last one — the number of jogging minutes per day – is the one with which the vast majority of homeowners struggle the most. The tankless propane heater (at full capacity) will be used for around 40 minutes per day in a typical household.

In addition, you may mess about with the numbers a little bit: As you can see, the quantity of propane required by a tankless propane water heater is dependent on its size, efficiency, and how much water it is used each day on a daily average.

How Much Propane Do Various Tankless Propane Water Heaters Use Per Year (Table)

If, on the other hand, you rely on propane to fuel your water heater, you will need to make the necessary preparations. The question is, though, how much gas does an RV water heater consume. No matter if you’re looking to make sure you have enough propane for your vacation or just want to figure out how much your water heater will cost to run, we’ve got you covered. So let’s have a look at how to rapidly estimate the propane use of your water heater.

Let’s get this party started!

How Much Propane Does an RV Water Heater Use?

You get the picture. The amount of propane your RV water heater consumes will vary depending on the size of your hot water tank, its BTU rating, how often and for how long you shower, how hot your showers are, how much hot water you use for cooking, the temperature your water heater is set at. you get the picture. As you can see, it’s a difficult question to provide a definitive response to accurately. However, with a little arithmetic, we can come up with a reasonable approximation. Let’s look at a concrete illustration: A camper or travel trailer equipped with a 6-gallon Suburban RV water heater rated at 10,000 BTUs will consume around 20 pounds of propane in approximately 42 hours of continuous usage, according to the manufacturer.

When it comes to heating the water in the tank, it only utilizes propane when it is necessary to do so, which takes roughly 10-15 minutes.

Important: Depending on your RV, your water heater is most likely simply one of numerous propane-powered appliances that you have.

As a result of the preceding example, we may obtain approximate answers to a number of often asked queries by campers about propane consumption and their water heaters.

How Long Will an RV Water Heater Run on Propane?

The 6-gallon Suburban water heater described above, together with the assumption that the heater works for an anticipated hour every day, would need 42 days to completely deplete a common 20-pound propane tank! There’s no need to be concerned if your water heater has a different BTU rating or if your propane tank is a different capacity. Using the following calculation, we can simply determine how long your RV water heater will be operational:

  1. Propane gallons multiplied by 91,502 equals tank BTUs
  2. Tank BTUs divided by total appliance BTU consumption equals number of hours before running out of propane
  3. Tank BTUs divided by total appliance BTU usage equals number of hours before running out of propane

For example, a fully charged 20 pound tank contains 4.6 gallons. We would multiply 4.6 by 91,502 to obtain the figure 420,909. After that, divide the result by the entire BTU consumption of our water heater, which in this case is 8,000 BTUs. The solution is 420,909 divided by 8,000, which is 52.6 percent. We can operate an RV propane water heater for 52.6 hours straight before running out of fuel, according to this calculation.

How Much Propane Does an RV Water Heater Use per Day?

Using our 6-gallon Suburban water heater example above, and assuming that your water heater runs for an hour on average every day, your water heater would consume 0.11 gallons of propane every day. Simply put, we took the number of gallons left in the tank (a 20-pound propane tank = 4.6-gallon propane tank) and divided that amount by the number of days it would take to burn up a full 20-pound propane tank to determine our daily use. 4.6 gallons of propane in the tank divided by 42 days is 0.11 gallons of propane.

How Long Will a 30 LB Propane Tank Last for Water Heating?

In our initial 6-gallon Suburban water heater example, assuming that your water heater works on average one hour every day, it would take 64 days to deplete a normal 30-pound propane tank! It is important to note that all of these computations are only estimates. The only way to know for certain how long your propane tank will survive is to put it through its paces in the field. If you have two propane tanks, you can complete this task quickly and safely. By doing so, you can see how long it takes to go through a single tank while still having a backup tank available in case the first one runs out.

However, in several regions of the world, propane is commonly measured in both liters and gallons; however, I prefer to use the latter because it is much more convenient. Tankless water heaters produce propane in a different way than conventional water heaters.

Some are capable of producing up to 9 gallons per minute.

You may obtain this information by multiplying the BTU rating of your tankless water heater device by 91,452 and dividing the result by 100.

You could be perplexed as to why your monthly propane use has increased significantly despite the fact that you don’t engage in numerous household activities. This is due to the fact that propane use is frequently influenced by a variety of circumstances.

Factors That Could Affect Calculation of Propane Consumption

Time allotted for use Inevitably, the more time you spend using your water heater, the more propane it will require to operate. Furthermore, different types of in-home activities need varying amounts of it. What household duties make the most use of your propane tankless system will be revealed over the course of a few hours. For example, you could take a hot shower for up to 10 hours straight or longer, but it would require more propane to keep it as hot as the first 10-minute hot shower in the morning would have required previously.

You must determine how many gallons per minute each of them consumes in order to get an accurate estimate of how much propane is required each month.

  • 0.5 to 1 GPM at the bathroom sink, 2 to 3 GPM at the kitchen faucet
  • Laundry 1.5 to 3.0 GPM
  • Washing Machine 2 to 3 GPM
  • Dishwasher 1.5 to 3 GPM
  • Shower 1.5 gpm to 3 gpm
  • Kitchen Faucet 2 to 3 GPM

I would recommend keeping a record of the instances where you run numerous fixtures at the same time. Keep note of the dates, times, and activities that occur during certain dates and times. If you repeat this process every week, you’ll begin to see a pattern or routine in your propane use. Temperature of the groundwater However, while it is obvious that propane lowers your family’s energy bills by a significant amount, you must also consider the total energy efficiency of propane. The first thing you should look at is where you are going to stay.

  1. If you reside in a frigid northern climate, it will take an excessive amount of time to heat water.
  2. If, for example, the normal groundwater temperature in your location is 52 degrees Fahrenheit, you would want a water heater with a capacity of 5 GPM that can raise the temperature to 53 degrees Fahrenheit in order to have adequately heated household water.
  3. As a result, if you lived in a colder region, you would want a water heater that could withstand the elements.
  4. Water that is hard to drink Investing in a water softener will be necessary if the water coming from the outside source is hard.
  5. The Number of People in the Household The following point was brought up briefly previously in the process of developing a propane consumption budget plan: The use of propane increases according to the size of the family.
  6. In a month, a household of two people will consume around 15 gallons of water, but a family of five or six members will use approximately 40 to 50 gallons of water each month.
  7. This one item alone accounts for a significant portion of the entire quantity of propane consumed.

Capacity of a Water Heater Tankless water heaters are available in a variety of styles, each with its own water-saving technology.

It will display the amount of propane that is consumed every hour.

A larger gallon capacity means that your model will convert hot water more efficiently than a smaller one.

It simply implies that the more the GPM capacity, the smaller the amount of propane required.

If you check at its features, you’ll see that it has a 7 GPM mechanism that would more than likely fulfill your propane conservation criteria.

According to my previous experience living with my mother, we would only need to pay 33 dollars per month on propane.

When compared to extended families, our propane budget is far less expensive and more cost-effective.

The amount of propane used by each family is determined by how they handle their water heating demands.

The more the number of times we use our water heater on a daily basis, the more propane is consumed. Check the specifications of your heater and apply the formula I’ve supplied to quickly calculate the total amount of energy consumed.


Calculating the total amount of propane you’ve used is less difficult than you would imagine. Propane use may be readily controlled if you have the right knowledge. Always remember to take into account the variables that influence your consumption. It will assist you in making an accurate computation. Units such as the Rinnai RU130iP tankless water heater come highly recommended if you are unsure of what type of tankless water heater to purchase. If you compare it to other types of heaters, it has a superior energy efficiency rating.

How Much Propane Do My Appliances Use?

If you use propane to heat your house, you may be curious in the energy consumption rates of the various appliances that are connected to your system. Depending on the size of your home, you may be utilizing a propane tank that holds 250, 500, or 1000 gallons of propane, respectively. The length of time that your tank will survive between fill-ups will be determined by the sorts of appliances that you have connected to your system and how you use those appliances. The obvious difference between a home of two and a household of nine is that a household of nine uses the shower, the laundry room, and the kitchen at a faster pace.

Britannic Thermal Units (BTUs) are a unit of measurement that specifies the amount of energy required to heat or cool one pound of water by one degree Fahrenheit (one degree Celsius).

To put this into perspective, one BTU is equal to one four-inch hardwood kitchen match that has been entirely consumed.

Take a look at the following numbers:

  • A pool heater that produces 425,000 BTU/hour or 4 gallons/hour
  • An HVAC furnace that produces 200,000 BTU/hour or 1 gallon/hour
  • A fireplace with ceramic logs that produces 26,000 BTU/hour or 1 gallon every three hours The following are the BTU/hour ratings for gas cooktops and ranges: 65,000 BTU/hour or 5 to 10 Gallons per month
  • Tankless water heater: 40,000 BTU/hour or 1.5 Gallons per day
  • Clothing drier that uses less than one gallon of gas every day (35,500 BTU/hr)

The numbers listed above will, to some extent, fluctuate depending on how much or how often you use your appliances, as well as the number of people that live in your home, so keep this in mind. Your propane provider can tell you how much propane you use and can assist you in determining how much propane to purchase and how often to acquire it. You may even wish to enroll in your supplier’s budgeting program to ensure that you will always have hot baths and hot meals available when you need them the most.

How Long Portable Propane Tanks Last

Small, portable propane tanks, sometimes known as DOT tanks, are used for a variety of applications including barbecues, water heaters, and fireplaces. They may weigh anywhere from 20lbs to 100lbs. The amount of time you can get out of it is determined by the size of your grill and how frequently you use your fireplace or heater. As a general rule of thumb, a medium-sized grill operating at high heat will consume around two pounds of fuel every serving.

According to this guideline, a 20-pound propane tank will give 18-20 hours of cooking time on a medium-sized barbecue grill. A bigger grill may consume up to 20 pounds of propane in as short as 10 hours if used regularly.

The Lifespan of Non-Portable Propane Tanks for The Home

In the summer, running out of propane in the middle of a backyard BBQ is a nuisance; however, running out of propane that is used to heat your house or water may be quite dangerous in the middle of winter. It’s critical to understand how much you consume and how to recognize when you’re running short. These heavy-duty propane tanks, which are also known as ASME tanks, are not portable and are often used to heat a house and power other household appliances such as cook stoves and water heaters.

Take these hypothetical usage stats:

  • Heating capacity: 85,000 BTUs
  • Cooking capacity: 63,000 BTUs
  • Water capacity: 199,000 BTUs

For a total BTU use of 347,000 in the residence. When you multiply that figure by the number of BTUs in a gallon of propane (91,502), you obtain an estimate of the amount of propane that may be burnt each hour. Assuming that each propane-fueled appliance is operating at maximum capacity for the whole hour. The way we use our furnaces, stoves, and hot water heaters, however, is quite different. It is possible that your furnace may run for 10 minutes out of an hour and that you will use the stove for half an hour.

With this type of usual usage, you’ll consume far less than 3.79 gallons per hour.

A smaller residence consumes less propane than a larger one, and vice versa.

Key Propane Usage Statistics

  • Each year, depending on how frequently the furnace is used, a house furnace consumes 500-1,200 gallons of propane. In order to heat their water, the average homeowner requires between 200 and 300 gallons of propane each year. The average household consumes around 2.5, 500-gallon propane tanks (or approximately 1,250 gallons total) of propane each year for heating and culinary purposes.

Although we recommend scheduling frequent fill-ups with us, you may learn to read your propane gauge and determine when you need a refueling appointment.

How Long Does a Propane Tank Last?

In addition to understanding how rapidly propane is consumed, it is critical to understand how long the tank itself will endure. At each filling, large permanent propane tanks, such as those used to heat houses and water, will be visually examined for any damage or corrosion. If your tank is in bad condition, we may refuse to fill it and instead propose that you replace it. Preventive maintenance is required on a regular basis in order to keep a propane tank in excellent working order. Regular maintenance involves a visual check of the tank, testing for leaks, monitoring the quality of the gasoline, and other procedures.

How much propane does a hot water heater use?

My prior trailer, which served as my first RV, was equipped with a fairly unusual hot water heater/”furnace” for the camper, which could be powered by either shore power or propane, depending on the situation. I never used the “furnace” feature and just used it for hot water needs, and I always opted to use the shore power supply instead of the generator. So, for the most part, the only propane I used in that small camper was for the cooktop burners. My new travel trailer, which I will be picking up in a few weeks, includes a more traditional furnace and a separate typical 6-gallon water heater, both of which I believe are only capable of operating on propane.

The trailer is equipped with two propane tanks weighing 20 pounds each.

I do want to keep one of the two propane tanks switched off so that when the first one empties, I can then turn on the second one and know that I have one full tank, but I am still expecting to get some sense of how much propane I may anticipate to consume in the future.

DW and I have recently returned from a three-month trip of the United States.

In addition, we have a shower in the trailer.

In addition, I switch off one tank until the first tank is completely empty.

Wishing you safe travels.

I switched the water heater between electric and gas to speed up the recovery time.

My hot water heater has a burner with a 10,000-btu capacity.

However, it does not operate continuously.

And, between the refrigerator, hot water, and cooking, we only used about a third of a tank of gas.

When I pick up my new trailer the next week, I will inquire as to whether the hot water heater can be operated on both electricity and gas; nevertheless, I will not be disappointed if it can only be used on gas.

I was spoilt, though, by the Alde heater that came with my first camper, not only because it was so adaptable, but also because it operated almost completely silently for the whole trip.

Additional factors include the temperature of the surrounding air and the temperature of the groundwater.

It also takes around a third more energy to heat water to 120 degrees if you’re replenishing it with 50 degree supply water (which is the case in northern places) than it does to heat water to 120 degrees if you’re refilling it with 70 degree Florida water.
