The Italian manufactured ATI Calorifier, or boat water heater, is an efficient method of heating water on your boat. The marine calorifier produces hot water from the mains 220v/110v or engine's cooling system, to feed into the hot water system. It can also be used with wet sourced heating systems.


These have been designed for use in the marine environment, primarily boats and yachts. They can also be used in 

mobile / vehicle and domestic applications.
