The Isotemp SpaStainless Steel Marine Water Heaters are available in 5 sizes ranging from 15 to 40 litres capacity (15, 20, 25, 30 and 40 litres).
All Isotemp tanks come with the innovative Isotemp Temperature Control Safety Mixing Valve as standard, which protects users from scalding hot water. Water heated with engine heat exchangers can be heated to 190 degrees or more which can scald those unfamiliar with boat water heaters. Water will also be heated to 160+ degrees 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.
