Tankless water heaters have become a very popular option for homeowners of the last few years, and for good reasons. However, it’s important to understand how a tankless water heater works in order to see the differences between a traditional water heater and a tankless one. While each type is very capable of providing your home with hot water, a tankless water heater can provide you hot water as you need it, versus having hot water on standby. The process isn’t as complicated as it can sound, as we’ll explain below.
How a Tankless Water Heater Works
There are two types of tankless water heaters:
- Point-of-use – small systems that typically mount underneath sinks, etc., to heat just that one outlet; point-of-use tankless water heaters are fueled by electricity.
- Whole-home – larger systems that heat water for your entire home. These systems usually use gas or propane, but can also use electricity.
No matter which type of tankless water heater you use, the heating process is the same. Tankless water heaters use heat exchangers to heat the water on demand; the heat exchangers reside in the core of the tankless system. When you turn on the hot water tap of a tankless system, the water flow starts the heat exchanger; the heat exchanger generates heat that is then transferred to the flowing water. As the water circulates through the heat exchanger, it absorbs the generated heat, and the hot water starts to flow from your faucets. All tankless systems have a maximum pre-set temperature in order to avoid scalding.
Benefits of Tankless Water Heaters
- Tankless water heaters can use up to 40% less energy than a standard tank water heater, which can reduce monthly utility bills.
- Tankless water heaters have a longer life span than tank water heaters (10 to 13 years vs. 20 years).
- Tankless water heaters take up far less space because they do not have a large tank attached to them.
