Can Tankless Water Heaters Get as Hot as Conventional Tank Water Heaters?
One of the concerns many homeowners have when making the switch from a conventional tank-style water heater to a tankless, or on-demand water heater, is whether it can get the water as hot as a tank water heater. The short answer is yes.
Most tankless water heaters have a thermostat that can be adjusted between 100° to 140°, depending on the brand and model. By comparison, most tank water heaters have the temperature set around 120°.
The key to ensuring the water heater can supply a consistent 120° or higher is the climate and number of sources the tankless water heater will need to supply. It is critical that a tankless water heater is sized based on a household’s needs. If the unit is too small for the amount of flow it’s being asked to produce it may work fine for a shower, but not work as needed when a washing machine and a shower are in use at the same time.
Tankless water heater ratings are based on the rise in water temperature they produce. The colder the temperature of the incoming water supply, the lower the maximum temperature of the heater. This means in a colder climate like Chicagoland, you’ll need a larger tankless water heater than someone living in a warmer climate, like Arizona.
