A calorifier is a simple and efficient means of heating water in your domestic system, for use with showers, taps and the galley. Comparable to a domestic boiler, these calorifiers have an inlet for cold water, but then use a link from the engines closed cooling circuit to heat the inner coil and therefore the water. The Hotpot range of calorifiers are also supplied with an immersion heater with a built in thermostat, meaning they can provide you with free hot water while motoring or charging the batteries.

The calorifier heats quickly as the drop coil technology ensures quick transfer of hear from the coil to the water. The outside of the calorifier is insulated in a polyurethane jacket designed to retain heat for up to 24 hours after the engine is switched off. Each calorifier is rigorously tested to ensure excellent quality and reliability.

Water stored in the calorifier reaches the same temperature as the engine, generally about 85°C. When hot water is needed, the calorifier uses a thermostatic mixing valve to combine this water with cold water to give the required water temperature.
