Please refer to our buying guide for information on the differences between electric, gas/propane, and hybrid fuel options. Select the Type of Heater You Want: Water heaters with storage tanks are the most prevalent form of water heater. They have an insulated tank in which water is heated and stored until it is required again. Tankless water heaters do not have a storage tank for hot water. As water travels through a series of coils, they heat it instead of using electricity. Direct vent water heaters suck in air for combustion from the outside of your home, rather than the interior. Afterwards, the exhaust gases and surplus heat are vented back into the atmosphere. See this page for additional in-depth information on the different varieties. Currently own a water heater and require its installation? Whether you want tankless water heater installation or gas water heater installation, we can help.

Water Heater Buying Guide

In a recent test, Consumer Reports evaluated six electric and gas whole-house tankless water heaters from manufactures including Bosch, Noritz, Rheem, Rinnai, Tempra, and Trutankless. A tanked water heater from Rheem, one that is gas and one that is electric, as well as an electric heat pump water heater from Rheem, which is a variant on a tanked water heater, were all used to compare the outcomes. Based on the results of an industry-standard “heavy usage” test, we compared the performance of natural gas and electric tankless water heaters to that of their conventional tank equivalents.

The daily equivalent of taking many showers, running the dishwasher, washing one load of clothes, and repeatedly turning the tap on and off.

Hot Water Heater Buying Guide

Taking a cold shower or paying high energy bills are not something anyone wants to do. Hot water heaters are important because they provide cost-effective and dependable hot water for your household.

Purchasing a Water Heater

Whether you’ve just experienced your first unexpectedly chilly shower or just want to lower your energy bills, investing in a new hot water tank is a wise decision. Follow these procedures to avoid having to guess about your appliance’s operation and fix problems:

  1. Determine the source of the fuel
  2. Select the type of heater you want
  3. Find out how much capacity you have
  4. Take a measurement of the space

Water Heater Fuel Sources

To begin, identify the sort of fuel source that is currently in use in your home. The following table summarizes the distinctions between electric, gas/propane, and hybrid fuel types.

Electric Hot Water Tanks:

  • To heat water, one or two interchangeable heating components should be used. Compared to other sorts, it is less costly. There is a wide range of high-efficiency alternatives available
  • Sizes range from 28 to more than 100 gallons.
  • It is necessary to use a burner to heat the water
  • It also requires flowing air around it. It is not possible to keep flammable items near by
  • Water heaters that use gas are more costly than electric water heaters. Water heaters that use less energy than electric water heaters
  • Sizes ranging from 30 to 100 gallons are available.
  • Make use of the energy in the air to heat the water
  • It is possible to utilize either outside air or air from the room where it is being kept. Water tanks are available as built-in units or as add-ons to existing tanks. Electric water heaters that are larger than conventional models
  • An early investment that is more expensive
  • It is more energy efficient, which results in cheaper utility expenses. Sizes available range from 50 to 80 gallons.

Types of Water Heaters

When selecting a water heater, take into account the size of your household as well as the availability of utilities in your location.

Storage Tank

This is the most often seen form of water heater. They feature an insulated tank where water is heated and kept until it is required. They are available in three different fuel types: electric, liquid propane, and natural gas. Water heaters powered by natural gas or propane often consume less energy and are less expensive in operation than electric versions of the same size. When purchasing a water heater, it is important to consider its energy efficiency as well as its annual operating expenses.

Tankless water heaters do not have a storage tank for hot water.

The fact that a tankless water heater only warms water as it is consumed means that it is often more energy efficient than a regular storage tank water heater.

Water Heater Tank Capacity

In the United States, storage tank water heaters are categorised based on the amount of water they can store in gallons. Identifying the amount of hot water your home requires on a regular basis is critical to ensuring enough hot water supplies throughout the year. With the exception of tankless water heaters, you’ll need a larger tank to accommodate a larger family. Another factor to consider when purchasing a storage tank water heater is the recovery rate, which refers to the number of gallons of water it can heat in an hour while simultaneously replenishing the tank.

If you want to utilize a tank water heater, you may use these suggestions as a reference to determine the size of the tank you’ll require.

Minimum Gallon Capacity Recommendations

30 gallons for a family of 1 to 2 people 40 gallons for a family of 2 to 3 people 50 gallons for a family of 3 to 4 people 80 gallons for a family of 5 or more people

Gas Water Heater:

Thirty gallons per person or every family of one to two people 40-gallon household (for 2–3 people) Fifty gallons per family of three or four people. Eighty gallons for a family of five or more

Space for the Water Heater

If you don’t have enough room for a standard-sized water heater, there are other options. All of these solutions give the same degree of performance and may be used with either electric or gas systems (natural gas or propane).

Lowboys or Short Water Heaters

These water heaters are both shorter and broader than a standard water heater. They contain the same amount of water as their larger counterparts while yet being able to fit into tight spots such as crawlspaces and below cupboards. Lowboys are available in sizes ranging from 30 to 49 inches in height and can store up to 50 gallons of water.

Tall Water Heaters

High-capacity water heaters are available in sizes ranging from 50 to 76 inches in height and can accommodate up to 100 gallons of water.

They’re perfect for basements or garages where there isn’t a concern about height. In addition, hybrid water heaters require additional room in order to perform correctly, so be sure to read the manufacturer’s instructions carefully before installing one of these units.

Advanced Technology

This feature is available for electric water heaters and prevents the higher element from burning out if the appliance detects that there is no water nearby.

ENERGY STAR ®and High-Efficiency Ratings

It is the most trusted and government-backed emblem of energy efficiency on the market today. This grade assists consumers in saving money while also conserving the environment via the use of energy-efficient items and procedures. Consider investing in a high-efficiency water heater to save money while also benefiting the environment. The energy factor (EF) rating of a water heater is used to determine its efficiency. The greater the efficiency factor (EF), the more efficient the model. However, while some of the most energy-efficient versions may be a little more expensive initially, they are meant to be more ecologically friendly and to save you money over time.

Using this information, you may get a better understanding of how the water heater model you’re considering is projected to function.

Intuitive Technology

A new generation of water heaters adapts the temperature and other operational aspects to your personal demands and usage patterns in a simple and easy manner. Improved energy economy, enhanced durability, and smarter performance are just a few of the advantages of choosing a heater that is integrated with artificial intelligence of this type.

A Premium Electronic Gas Valve

Certain gas water heaters now include an electronic gas valve, which is more efficient. This results in more consistent and precise performance for better temperature control and faster hot water recovery than a standard mechanical gas valve since it has fewer moving parts than a mechanical gas valve. Using a light-emitting diode (LED) indicator, you can validate that the pilot is lighted and get diagnostic input on how well the system is performing. With a thermopile, this novel valve can operate entirely on its own power.

Because there is no requirement for an external power supply, installation is straightforward.

Wi-Fi Water Heater Capabilities

Electric water heaters that have a Wi-Fi module are currently available on the market. It allows you to regulate the temperature of your water from a distance. Set up a customized schedule so that hot water is only accessible in your water heater tank when it is needed, resulting in significant savings on your energy expenditure. It will also give you an alarm if your hot water supply is running low.


Water heater accessories are available to help you increase the safety and efficiency of your water heater by enhancing its functionality.

Expansion Tanks

The water heater’s expansion tanks are connected to the water heater by a plumbing system. It is the purpose of these water heater tanks to store the additional volume of water that can be created when cold water is heated in the tank.

Water Heater Timers

Hot water heater timers are linked into the unit’s electrical supply and may be programmed to ensure that the water heater only uses power during specific hours of the day or night.

By only using the water heater when it is absolutely necessary, you may reduce your energy consumption and save money.

Water Leak Detectors and Alarms

Water leak detectors can be found on the floor or in a pan beside the water heater, depending on the model. A liquid leak or overflow will cause the alarm to detect the liquid and sound an audio alarm, alerting the homeowner that there is a problem. Some of these alarms are also integrated with Wi-Fi, allowing you to get notifications on your smartphone.

Water Heater Insulation Blankets

They are designed to be installed above the unit and to improve the insulating properties of the water heater. Heating systems installed in garages or other unheated areas benefit from the use of insulating blankets.

Water Heater Pans

There are many pans that sit beneath the heater and catch water from leaks or overflows produced by excessive pressure in the tank. The side of the pan features a hole for a drain hose, which may be used to remove any excess water.

Water Heater Stands

Water heater stands elevate gas-powered units off the ground, reducing the risk of a fire in the case of a flammable liquid spill in the immediate vicinity of the unit. If you’re replacing an old water heater and installing a stand along with your new one, your measurements, piping, and venting will be affected as a result. It will be necessary to hire a professional to install it if you do not have extensive plumbing expertise.
