What is Flow Rate?
The amount of hot water you must generate per minute in order to meet the maximum level of demand for hot water is referred to as the flow rate. It is common for the flow rate to be fairly high in restaurants and business establishments.
How to Determine Your Flow Rate
- Make a list of the hot-water gadgets that are most likely to be utilized at the same time and how much hot water they will consume. Add in sinks for dishwashing, hot water for food preparation, and restrooms for customers. Then sum up the entire amount of hot water that will be required for all of these functions
- This is the total amount of hot water necessary. The total gallons of hot water is the flow rate, and it is this amount of hot water that your tankless system will be required to generate during peak demand periods.
What is Temperature Rise?
Temperature rise is the change in temperature between when water is first introduced into your facility and when it is hot enough to be utilized. For example, if the water is 50 degrees when it is brought in, and the desired temperature is 130 degrees, the temperature rise will be 80 degrees. You must ensure that the system you pick is capable of heating the water to this temperature consistently and with little change over time.

When you purchase a new water heater, it is reasonable to assume that the device would operate flawlessly and provide hot water whenever it is required, day or night, year after year. There are a variety of sizes available, ranging from small point-of-use and medium tankless water heaters to huge tank types and boilers for high-demand applications. Tankless heaters, for example, provide hot water on demand and constantly, and their output may be increased by employing the multi-system approach and linking numerous units together to form a single system.
In order to fulfill the needs of your house and family, as well as the demands of numerous applications, including showers, dishwashing, and laundry, the tank-type heater must be appropriately sized.
Is your water heater undersized?
A heater that is too small will not deliver enough hot water, and it may even result in overheated water. Due to drops into the flame, it may also cause condensation and a pilot flame to go out on the stove. The following are some of the most common signs of an undersized water heater:
- There isn’t enough hot water. Condensation in abundance
- On the burners and flue tubes, there are rust chips. Failure of the tank before its time
Because improper water heater sizing might result in problems that shorten the heater’s life expectancy, undersized systems are not eligible for consideration under the warranty.
The purchase of an appropriately sized tank, on the other hand, will decrease burner or other element activity when just a small quantity of hot water is required, resulting in less stress on these components. Sizing also refers to being appropriate:

Having the proper water heater size is critical, especially when significant amounts of hot water are required in a short period of time. On the other hand, if the peak consumption period lasts for a lengthy period of time (greater than two hours), the heater recovery rate becomes increasingly essential. Another expert recommendation is to choose a heater with the greatest Energy Factor possible (EF or UEF).
Even though they are more expensive, with a higher EF, you will be able to purchase Electricity Starmodels, save money on energy, and qualify for a refund through government programs.
A water heater’s physical limits, such as its diameter and height, must be considered before purchasing one.

- Here are some consumption rates to give you an idea of how much water is required by a certain application:.
If you have a storage tank-type heater and you want more hot water than your present conventional unit can offer, you may want to consider purchasing a high recovery unit or splitting the system and installing two units.
Sizing and first hour rating chart
Avoid making the same error as the majority of consumers and purchasing a water heater based on the size of the storage tank. The ability to meet peak hour demand or the first hour rating is more significant. It is possible to find this information on the Energy Guide label or in the Energy Guide booklet. The first hour rating is a measure of how much hot water a single unit can supply in one hour. For natural gas, for example, the first-hour rating might range from 40 to more than 100 gallons depending on the source.
Consider the following scenario: A 40-gallon natural gas heater holds 31 gallons of useable hot water and provides 41 gallons of usable hot water in the first hour, yielding a first hour rating of 72 gallons for the heater.
The following is what we discovered after consulting the AO Smith water heater selection guideline for a variety of household sizes: The number of people in the family 2 persons are involved.

- Contrary to popular belief, do not purchase a water heater solely on the basis of its storage tank capacity. Most crucial is the demand capacity during peak hours, often known as the first hour rating It is possible to get this information on the Energy Guide’s label or in its booklet. This rating indicates how much hot water a unit can deliver in the first hour of operation. Typical first-hour ratings for natural gas range from 40 to more than 100 gallons, depending on the kind of fuel. Presented in gallons, this figure is a mix of the amount of usable hot water kept in the tank and the amount of usable hot water that the heater can create in one hour of operation. Consider the following scenario: A 40-gallon natural gas heater holds 31 gallons of useable hot water and provides 41 gallons of usable hot water in the first hour, yielding a first hour rating of 72 gallons. As a consequence of the high first hour rating, you may purchase a smaller model, which will result in good performance even during peak times and periods of heavy demand, while minimizing cycle and standby losses. This is what we discovered when we looked at various family sizes and the AO Smith water heater selection guideline. Size of the family for a total of two individuals there are three individuals a total of four individuals the number of participants is five. a total of six individuals a total of seven individuals The need for FHR (gal) 45-55-65-75-85-100-100-100-100-100-100-100-100-100-100-100-100-100
What are the popular sizes?
In the United States, the most often utilized tank size (based on a typical family size of four to six people) and the general guideline for water heater sizing are as follows:
- 30 gallon unit – sufficient for a one-bathroom residential house or apartment building
- 40-gallon water heaters are recommended for two-bath residential houses or two applications
- 50-gallon water heaters are recommended for three-bath residential homes or three applications. Take a look at the best gas and electric vehicles
As a general rule of thumb, if you want to use an electric heater for a family of four in a home with two full bathrooms, as well as a washer and dishwasher, your tank size should be in the 50 to 80 gallon range and the power provided by the heating elements should be around 5.5 kW. It is recommended that a 50-gallon tank with a gas input of 40,000 BTU/hr be used for the same requirements if gas is being used instead of electricity in this case. When sizing a water heater, keep the following factors in mind:
- Because of the immersion installation of electric heaters, they have recovery efficiencies that are near to 100 percent. Gas heaters have a recovery efficiency of roughly 75%, which implies that the water absorbs 75% of the total heat produced by the burner in the tank, with the remaining 25% being wasted as energy. Additionally, keep in mind that around 70% of the hot water is pulled out before being diluted by the entering cold water. The hot water produced by a 50-gallon tank, for example, will be 35 gallons per hour of useable hot water.

Tankless Water Heaters: How Well Do They Work for Restaurants?
Several studies have demonstrated that tankless water heaters are a feasible alternative to traditional storage-type water heaters in residential and light commercial applications. The question is, how well do these sorts of hot water delivery systems perform in situations when a continuous, high-volume supply of hot water is required? In general, tankless water heaters may perform just as well as storage-based devices in a restaurant or other business facility that receives a high volume of usage.
- A Brief Overview of How Tankless Water Heaters Work In contrast to traditional water heaters, tankless water heaters do not have a storage tank where hot water is maintained until it is needed.
- Using electricity or gas-fired burners to power heating elements, incoming water is swiftly heated to the desired temperature.
- Tankless water heaters are particularly energy efficient because of this manner of producing and distributing hot water.
- Additionally, there is no risk of a hot water tank running out of hot water during peak consumption periods or when hot water is required for dishwashing or other sorts of cleanliness.
- The selection of tankless water heaters in a restaurant or other business environment will be guided by three very significant considerations: size, flow rate, and temperature rise.
A number of tankless water heaters will often be required to provide the hot water demands of a restaurant, but the number of heaters and their capacities (size) will be determined by the required flow rate and temperature rise.
- When it comes to tankless water heaters, sizing entails estimating how much capacity each unit must have in order to generate the amount of water necessary for the restaurant’s operations to run smoothly. The units must be correctly designed to guarantee that there is enough hot water available to fulfill demand during peak periods, such as the lunch rush or the late dinner rush. Proper sizing necessitates the knowledge of the needed flow rate and temperature increase that the tankless unit must offer by both you and your plumbing specialist. Flow rate: Flow rate is the amount of hot water, measured in gallons per minute, that must be generated per minute in order to meet the greatest level of demand for hot water in the restaurant. Most commercial settings, including restaurants and other business establishments, have high flow rates. Identify which hot-water devices are most likely to be in operation at the same time and how much hot water each item will require before determining flow rate based on this inventory. A restaurant’s amenities must have things like sinks for washing dishes, hot water for food preparation, and restrooms for your clients. Add up the total amount of hot water that will be necessary for all of these tasks. The flow rate, or the amount of hot water that the tankless system must be able to generate in order to satisfy the greatest levels of demand, is measured in gallons of hot water per minute. Temperature rise: Before any water can be utilized in your restaurant, it must first be heated to the proper temperature. The temperature increase is defined as the difference in temperature between water when it first enters your facility and water that is hot enough to be utilized. Example: If your water is delivered at 50 degrees and you want hot water at 130 degrees, the temperature rise is 80 degrees. Figure 1: Water must be heated to this degree consistently and with little temperature change in order for the tankless system to be effective.

How to size a commercial water heater
Flexiheat demonstrates how to properly size an industrial water heater. For showers, restrooms, kitchens, restaurant sinks, washing machines, and other uses in a commercial or industrial structure, such as schools, hotels, gyms, or hospitals, a commercial water heater is necessary. In order to heat cold water to the necessary hot water temperature, a commercial water heater employs electrical components or a burner, which is activated when a demand for hot water is made on the water heater. Water heaters may be equipped with a tank that stores hot water until it is needed again.
Many industrial water heating applications, such as commercial laundries or other purposes, where hot water is necessary for a production process, such as when creating a product or service, are also made possible by these boilers.
Using an incorrectly sized commercial water heater can result in your clients being angry if you are running out of potable hot water at a hotel, or your production process failing if you are using a hot water process in a manufacturing facility, for example.
Commercial water heater definition
A water heater may be defined as a closed tank that is used to deliver potable hot water. It can be heated by electricity, gas (natural gas or LPG), or any other source, such as solar energy, to provide hot water. It is intended for the water heater to be supplied with potable water either from a potable water source, such as directly from the water mains system (in which case it is referred to as an unvented hot water system), or from feed tanks when used in an open vent hot water system.
The three vital elements to bear in mind when sizing a water heater for commercial or industrial applications
Water storage tank capacity refers to the amount of water that may be stored in a tank or vessel to provide hot water when needed. The tank enables for the drawing of a large volume of water at flow rates that can exceed the recovery capacity of the water heater, which is particularly beneficial during periods of high demand. It is the volume of water elevated in litres per hour for a certain temperature rise and kW input that is measured as the recovery rate. Another number that is frequently mentioned is the water heater’s one-hour draw capacity, which is the maximum amount of hot water it can produce for one hour and is generally necessary during the busiest part of the day when the most demand for hot water will occur.
The amount of energy required by the water heater is given by your choice fuel, which can be either electric, gas, or oil.
The combination of these three parameters is used to determine the appropriate water heater size and power rating.
The most effective way for purchasing a commercial or industrial water heater is to consider how much hot water will be used. The tank size, recovery rate, and heat input are all taken into consideration before making the final decision.
What size water heater do I need calculation for commercial water heating applications
As a guideline, the following is the European standard for hot water needs to DIN 4708, which is typically used for sizing a commercial or industrial water heater, depending on how you intend to utilize the unit.

Example of a calculation for the hot water demand of a commercial water heater Litres of hot water per hour at 60 degrees Celsius for a 100-room hotel
- There are 100 bath tubs or showers and 25 bidets. There are 100 private wash basins and 375 public wash basins. There are 5 bar sinks and 8 kitchen sinks. There are 5 slop sinks and 100 bath tub/showers and 5,000 bidets.
With a total hot water demand of 8,015x the demand factor for a hotel water heating system sized at 0.5 = 4,007.5 litres per hour continuous at 60 °C, we have an estimate of the total hot water demand. A commercial storage water heater is the only practical solution for a commercial hot water requirement / application of this nature due to the volume of water required. We offer a full range of commercial gas water heaters that can be matched to various storage volumes of up to 5,000 litres in a single storage tank (more when used in series) and a power input of 300kW.
A selection of oil-fired commercial water heaters is also available, with the fuel for these being gas oil, which has become the preferred oil for usage in commercial and industrial water heating applications over the years.
Hot water demands for apartment blocks with a communal / centralized hot water system
Conforming to DIN 4708, a typical apartment or flat is described as consisting of four rooms, with three or four people living in each room, a 150-litre bath (with a fill time of ten minutes), one wash basin, and one kitchen sink, as well as one toilet. Additionally, the standard stipulates that the hot water storage capacity as well as the performance of the heat exchanger in terms of efficiency are both important considerations in determining the number of apartments that a water heater or a series of water heaters can service.
| Number of apartments | continuousrequirement (litres per hour) | |
| Domestic Hot Water Temperature | 60 °C | 45 °C |
| 50 | 3000 | 4300 |

| 250 | 10700 | 15500 |
| 300 | 12000 | 17400 |
Commercial electric water heater sizing
When sizing a commercial electric water heater, you follow the same guidelines as when sizing a gas or oil-powered version; the only difference is that you need electricity as the fuel source or power source for the water heater. So, using the information above, determine your hot water requirements, and then visit our webpagecommercial electric water heaters to see what sizes and power outputs are available that we can offer. Just make sure you have enough Amps available to power the machine before you begin.
Commercial tankless water heater sizing
Business tankless water heaters, on the other hand, heat water on demand rather than holding it in a storage tank for later use, making it more difficult to size a commercial tankless water heater. This implies that they are typically more energy efficient than storage water heaters because they only ever heat the amount of water that you use and are smaller in size. However, they have a disadvantage in that heating water on demand necessitates the use of a larger burner in the case of a gas or oil-fired commercial water heater or electrical heating elements than would be required by a commercial storage water heater, resulting in a higher energy demand during the heating process.
The most popular type of commercial tankless water heater is powered by gas, which may be either natural gas or LPG gas.
Commercial tankless water heaters are sized based on the number of hot water outlets they must supply, as well as the temperature of the water they must provide – we go into more detail about this on this dedicated webpage –gas multipoint water heaters, which are used in commercial tankless hot water systems.
Industrial water heater sizing / calculation
Commercial tankless water heaters, on the other hand, heat water on demand rather than holding it in a storage tank for later use, making it more difficult to size a residential tankless water heater. Because they only heat as much water as you use, they are often more energy efficient than storage water heaters, and they are also more compact. On the other hand, they have a disadvantage in that heating water on demand requires the use of a larger burner in the case of a gas or oil-fired commercial water heater or electrical heating elements than would be required by a commercial storage water heater, resulting in a significantly higher energy demand during the heat-up phase.
A natural gas or LPG-fueled tankless water heater is the most prevalent type of commercial tankless water heater, as gas (either natural gas or LPG gas) is excellent at producing a lot of energy from a small amount of water.
You can size commercial tankless water heaters by the number of hot water outlets they must satisfy, as well as the water temperature they must maintain (we go into more detail on this on this dedicated webpage).
