Types of tankless water heaters
There are different types of tankless water heaters: electric and gas and condensing vs non-condensing.
Electric tankless water heaters
These water heaters use electricity to heat the water as it flows through the unit. They are typically smaller and less expensive to purchase and install than gas-fired tankless water heaters, but they may not be as powerful and may take longer to heat the water. They also require a dedicated electrical circuit with sufficient amperage to power the unit.
Gas-fired tankless water heaters
These water heaters use natural gas or propane to heat the water as it flows through the unit. They are generally more powerful than electric tankless water heaters and can supply hot water to multiple fixtures at once. Gas-fired tankless water heaters require proper venting and a gas line to the unit, which can increase installation costs. They also require periodic maintenance to ensure efficient operation.
Condensing vs non-condensing tankless water heaters
A condensing tankless water heater is a more advanced type of tankless water heater that captures the heat from the exhaust gases and uses it to preheat the incoming cold water, making the unit more efficient.
A non-condensing tankless water heater, on the other hand, simply exhausts the hot combustion gases outside and does not recover any of the heat that is lost in the exhaust.
It’s important to choose the right size tankless water heater for your needs based on the number of people in your household, your hot water usage patterns, and the climate in your area. A professional installer can help you determine the appropriate size and type of tankless water heater for your home.
