Is Water from a Tankless Hot Water Heater Hot Enough?
By: Danny Lipford
I would like to put in a tankless hot water heater, but I’m concerned that the water will not get hot enough. Is that a problem?” -Gail
Tankless water heaters can get the water plenty hot enough. Depending on the brand and model, most tankless water heaters have a temperature setting that is adjustable between 100° to 140° (most tank water heaters are set around 120°).
In order to make sure the water will be hot enough, it’s important that a tankless water heater is sized based on your climate and hot water needs.
- Size tankless water heater to the water supply temperature: Tankless water heaters are rated based on the rise in water temperature they produce. The colder the temperature of the water supply coming in, the lower the maximum temperature of the heater. So if you live in a cold climate, like Alaska, you’ll need a larger tankless water heater than someone living in a warm climate, like Florida.
Good luck with your project,
