What is a Calorifier? A calorifier otherwise known as a boat water heater. They offer you an efficient means of heating water on board your boat for your water system allowing for hot water in taps and showers around the boat.
How does a Calorifier work? Calorifiers don't contain their own burner, like a household boiler. The water in calorifiers is either heated indirectly by a source such as your boat's engines, or they're heated directly electrically by a built in immersion heater.
Calorifiers are well insulated with high-density polyurethane foam and can keep the stored hot water at a good temperature for up to 24 hours. So if you're looking to add domestic hot water to your water systems on board take a look at the water heater options we have available to you from 15 litre units up to 40 litres.
