3 Things You Need To Consider When You Are Ready To Purchase A Tankless Water Heater

 If your old water heater is on its last legs and you want to replace it with a tankless device, there are certain factors you need to consider before you part ways with your money for a new appliance.

After you do your research, taking into consideration the factors below, do not forget to ask the manufacturer and your utility company if there are any rebates or incentives you can take advantage of to lower the initial cost of your brand new tankless water heater.

Groundwater Temperature

It is important for you to know the average temperature of the groundwater in your area when you purchase any kind of appliance that uses a heat pump. The groundwater temperature affects the temperature of the water that enters the water heater and how much the device needs to work to warm up the water.

You will need a powerful tankless water heater if you live in a cold climate because the device will need to work harder than it would in a warm climate to heat up the water that enters the device.

Contact your water utility company or the nearest branch of your state's cooperative extension to find out local groundwater temperature details.

Fuel Type

Tankless water heaters can operate via electricity, natural gas or propane. If you were happy with the power source for your old water heater, you may not want to change to another type.

However, you should compare the energy costs of the different sources as a precaution, especially if your goal is to save money on utility bills with your tankless device.

The U.S. Department of Energy as well as some utility companies offer online calculators and comparison charts to help you determine water heating costs by fuel.


Some tankless water heaters come with safety features. If you want to control the temperature of hot water with precision, opt for an appliance that has a water temperature safety control. If you have children, this is an important feature to prevent small kids from burning themselves when they use the water faucet or take a bath.

If you live in a cold climate, look for a device that has an internal freeze protection system. This will keep the device running properly and prevent pipes from freezing even when temperatures are below freezing outside. If you purchase a natural gas or propane-powered tankless water heater, make sure that it comes with sensors that will shut off the appliance if carbon monoxide is detected.
