Isotemp Water Heater - Slim 25L with Thermo Mixing Valve

The Isotemp Slim 25l Water Heater comes with a brushed stainless steel cover, a stainless steel tank all combined in an innovative internal design. It achieves the highest capacity and efficiency by optimized installation of the engine water heat exchanger as well as the immersion heater.

Thermostic Mixing Valve

All Isotemp water heaters come as standard with the innovative Isotemp Temperature Control Safety Mixing Valve which protects users from scalding hot water.  Water heated with engine heat exchangers can be heated to 90C or more which can scald those unfamiliar with boat water heaters.  Water will also be heated to 70C+ with just the electric heating element alone. By adjusting the valve, the Isotemp thermostat-controlled mixing valve mixes the boat’s water with the hot water to deliver the temperature you want at the faucet. This mixing action also speeds recovery time and extends the volume of hot water you get from a smaller tank.
