Things to Consider when Buying a Tankless Water Heater

Water heater temperature adjusterTankless water heaters are more energy saving than conventional tank-type units, but not all will necessarily reduce your home’s energy consumption significantly. If you buy the right product, you can’t expect great savings.

To help narrow your options down, consider these four important factors:

Hot water demand

Place a premium on your household’s regular hot water needs. A large tankless water heater in Utah can serve multiple faucets at a time, but a small one might not provide enough hot water for simultaneous uses.

Also, think about the application. Do you need it for showers only, or for dishwashing too? If your appliances need to share your water heater with your family, invest in a bigger one to ensure efficiency.

Fuel type

Water heaters use different energy sources. The most popular ones are electricity and fuel oil. If you want to buy a unit that runs on solar or geothermal energy, make sure the energy source is always available and doesn’t go out quickly to get hot water on demand.

BTU rating

When choosing a tankless water heater system, focus on its flow rate rather than its capacity. This way, you can select a product that can work efficiently with your local climate in mind. To do that, look at the British Thermal Unit (BTU) input of the unit. This rating tells you how much energy the product needs to raise the temperature of one pound of water 1° F. The higher the BTU rating, the greater the product’s flow rate.


By and large, tankless water heaters outlive their tank-type counterparts by five to 10 years. Nevertheless, choose a unit that comes with a powerful warranty to protect it from premature failure. Make sure critical components, like the heat exchanger, are covered to get the most bang for your buck.

Right-sizing and faultless installation are key to optimizing the performance of your tankless water heater. Buy only from a reputable company and don’t set it up yourself to guarantee its long-term reliability.
