Smart Adjust Modulation, Energy-saving

Comes with micro-computer control and patent heating technology for stable temp outlet, the on demand electric tankless water heater adjusts power input based on flow rate and temp setting in real time.

3 Smart Steps for Choosing Tankless Water Heater Electric




It is important to figure out your average inlet water temperature, this determines if you can get hot water of desired temp from the hot water heater. Outlet water temp equals inlet water temp plus temp raise(by the tankless hot water heater).

Check the chart to figure out the flow rate advised for your area and the corresponding outlet water temp, to see if it meets your need. For example, if inlet water in your area is 67℉, you are able to get 1.5GPM hot water @ 106℉, if you reduce water flow, you are able to get more than 106℉,correspondingly.

Determining specs and electrical infrastructure is important, because without the correct infrastructure, your electric hot water may not fit into your breaker panel and work properly. Please make sure these information before purchase and installation.
