Isotemp Marine Water Heaters



Isotemp water heaters are specifically designed for use on yachts and boats. Only high quality components are chosen to ensure the best product performance.

The Isotemp water heater comes with a brushed stainless steel cover as well as innovative internal design. It achieves highest capacity by optimised installation of the engine water heat exchanger as well as the immersion heater.

They 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 especially designed to minimise the mixture of cold and hot water.
