Considering a tankless water heater? Read this first.

Those of us who have been around for a while are used to the idea of hot water heaters having a tank but times, they are a changing. Tankless water heaters (“instantaneous” water heaters) are becoming more popular as long-term economic and environmental concerns enter more strongly in the decision-making process.

Increasing options

WaterHeaterStore.co has a growing number of tankless water heater models available including electric tankless water heaters, commercial natural gas tankless water heaters, residential natural gas tankless water heaters and propane tankless water heaters.

Tankless water heaters are also called instantaneous water heaters because they don’t store water. Instead, the water flows through the device. The flow sensor fires the burner each time water is needed.

Last month, we talked about how tankless water heaters are the more eco-friendly choice. According to Consumer Reports testing, gas powered tankless water heaters were 22 percent more efficient compared to their traditional natural gas water heaters.

How to choose a tankless water heater?

It’s not just the shape that’s different with these products compared to traditional water heaters. There are a few different aspects to consider.

  1. Capacity: capacity in tankless water heaters is expressed in gallons per minute (that can be warmed) versus the traditional water heater capacity that is listed in gallons that can be stored at once. It’s very important to make sure you get a large enough capacity tankless water heater because otherwise you will experience less than pleasant results when the water is not able to heat well enough for your needs.
  2.  Location: You need to consider where the unit will be used when deciding how big of a tankless water heater to purchase. For example, if your Rheem RTG Series residential natural gas water heater is being installed in a cold garage up north, you will need a larger capacity tankless water heater than if you are installing one in a location that is warm all year round.

 Why is this?

The same model that produces 7.2 gallons per minute in a warm place will put out almost half that in a cold location because the colder temperatures make more “oomph” necessary to raise the temperature to the desired level from a colder starting point.

Gas vs. electric tankless

Similar decision making must go into purchasing other types of tankless water heaters, including  the Chronomite electric tankless water heaters. If the design of your building will allow for it, electric tankless water heaters might be preferable because they eliminate the possibility for gas leaks (because gas isn’t being used).
