Many boat owners are happy to rough it with a kettle as their only source of hot water. Others value the convenience of harnessing ‘free’ excess heat from the engine to warm a tank of water.
Typical systems have a calorifier tank in which the water is heated by the fresh water side of the engine’s cooling system. This circulates through a coil of pipework within the body of the calorifier. In addition a 240V immersion heater, typically of around 1kW, can be fitted for use with shore power when in a marina.
“The best calorifiers are made of copper,” says Ashley Bradley of ASAP Supplies, who offer a wide range of products for water systems. “They retain heat for up to 24 hours and have better antibacterial properties.”
Sizing a calorifier tank is not an exact science and Bradley says it’s often determined by the available space, but where possible he advises always opting for a larger unit. As a rule of thumb, a 30lt model is likely to be fine for 3-5 minute showers for a couple of people.
The calorifier needs a pressurized supply from the main water tanks. A mixer valve is also fitted to regulate water temperature and prevent it from coming out of the taps scalding hot.
