New Webasto Marine Isotemp SPA water heater with thermostat.

Isotemp water heaters have a good water heating performance thanks to thick insulation and smart design. The motorised water heat exchanger, as well as the electric heating element, is located at the lowest part of the tank where the water is coldest to ensure even heating of all the water in the tank. The water inlet and outlet pipes are specially designed to minimise the mixing of hot and cold water.

The Isotemp SPA hot water tank is designed for demanding boating applications. The water heater has a 750 W/230 V resistor and a thermostatic valve (mixer) as standard to prevent excessively hot water coming from the tap, as well as a LK 6 bar relief valve. The heater has a thick polyurethane insulating layer which provides good thermal insulation.
