Calorifier tanks are otherwise known as a water heater for your boat. They offer you an efficient means of heating water on board for your water system allowing for hot water in taps and showers around the boat.
Calorifiers aren't a fired water heater, like a household boiler. The water in a calorifier tank is either heated indirectly by an external heat source such as your boat's engines, or they're heated directly electrically by a built in immersion heater.
Hot water 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.
