Amtrol® invented the first water heater, using the existing energy in a boiler to minimize fuel use and maximize hot water output. More efficient than conventional gas or electric water heaters, BoilerMate® provides faster recovery, requires no separate flue and features a replaceable heating element. Compared to tankless wall-hung water heaters, BoilerMate® provides built-in storage for high demand requirements or when power outages occur and a faster payback. BoilerMate® is available in top or bottom connection models for maximum installation flexibility.
