Comparing Electric Tankless Water Heaters

Here are some factors to consider when comparing electric tankless water heaters. Because most electric units are 99% efficient and have comparable expected lifetimes, electric tankless water heaters are best compared by performance and reliability.

  • Quality
    • Purchasing a unit with third party certification(s), such as UL and ETL, is very important. The best way to judge the quality of an electric tankless unit is to look at the company producing it. Do they have a long track record of reliability and good customer service? It pays to do your homework here.
  • Capacity
    • The greater the kW of a unit, the more hot water it will produce. It is vital to know your voltage before determining the kW. Lower voltage means lower kW. Higher kW means more hot water, but requires larger or multiple wires and circut breakers. It is critical to choose a unit your electrical system can handle, in addition to providing adequate hot water.
  • Other considerations
    • Other features to consider are activation flow rate, ability to work with preheated water, temperature control, warranty and overall build quality.
