This slim line, box style water heater has been designed for easy installation in narrow spaces. The Isotemp Slim Square has a capacity of 16ltrs and effectively heats water up via the boat engine or by the electrical heater element if the boat is connected to shore power. The water is heated to above 70°C which enables water to be heated on board at the correct levels for both hygiene and safety purposes.
It can be installed in a variety of positions, making it more versatile than standard models currently available. As with all Isotemp water heaters, the Isotemp Slim square has been constructed with a robust acid proof stainless steel (AISIS 316) and fitted with special components to protect it from overheating.
It also features a safety valve with a built-in two-way check valve, which reduces or prevents water normally forced out by expansion. It also has a drain point fitted as standard to enable easy winterisation of your boat.
At thermostatic mixing valve can be fitted as an option.
The safety valve is set to 5.5 bar/80 psi on this model.
