Isotemp SPA Stainless Steel Water Heater - 25L with Thermo Mixing Valve

Isotemp SPA Stainless Steel Marine Water Heaters or Calorifiers as they are sometime known are specifically designed for use in the demanding marine environment.  The new Isotemp SPA line features a more economical polypropylene cover and a 316-grade  stainless steel inner tank that is backed by a 5-year limited warranty against leakage due to corrosion or manufacturing defect.

Isotemp SPA Stainless Steel Water Heaters achieve the highest capacity by optimizing the position of the engine water heat exchanger as well as the electrical immersion heater. These are positioned in the lowest part of the tank where the water is coldest in order to ensure an equal heating of all the water in the tank. The water inlets and outlets are specially designed to minimize the mixture of cold and hot water

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.
