Isotherm Slim Water Heaters (Stainless Steel)

Isotemp Slim and Basic water heaters are premium-quality units featuring brushed stainless steel casings and an innovative internal design. They achieve maximum efficiency thanks to the optimised positioning of the heat exchanger, which uses engine coolant, and the immersion heater. These components are located at the lowest point of the tank, where the water is coldest, ensuring even heating of the entire water volume. The water inlets and outlets have been specially designed to minimise the mixing of cold and hot water.
