thermomate Water Heaters ES Editorial Review
The thermomate Mini Tank Electric Water Heater is a great option for those needing instant hot water under the kitchen sink. It heats water all the time when water temp is below your setting and should be turned off if you leave for days. The 2.5-gallon model performs better than the 1.3-gallon model. It is enough for two sinks as long as they are not far apart. The unit can be used in a food truck if a water pump and reservoir are installed. There is no reset button, and the unit can be unplugged instead. The water heater can be drained, and it can be used to replace a water heater in an RV.
