When purchasing an electric tankless water heater, make sure you consider the following two factors:
The majority of the electric tankless water heaters come with a coverage of 3 years to 12 years. For models that come with longer warranties, you will generally have to pay a little bit more; however, models with longer warranties tend to have better elements that speed up the heating of water.
Similarly, models with longer warranties also feature thicker insulation so that there is less loss of heat. Therefore, you must pick out an electric tankless water heater with a long warranty.
- Flow rate
When searching for a good electric tankless water heater for your house, you will have to think not in terms of the capacity of the heater, but in terms of flow. An electric tankless water heater can’t run out of the water as a tank water heater can. However, if the flow isn’t right, then the heater might not be able to heat water quickly so that it serves numerous showers or sinks at once.
The flow rates can vary anywhere from 1.2 GPM to up to 6 GMP, so you will have to choose one according to the size of your house and the number of fixtures that will be running at one time.[/spoiler]
