Vetus WHT025 25-Litre Twin Coil Marine Water Boiler – Technical Specifications
The Vetus WHT025 is a compact 25-litre twin-coil marine calorifier designed to provide hot fresh water onboard by utilizing surplus engine heat as well as a secondary onboard heating circuit. In addition, a 230V / 1500W electric heating element is built in to ensure hot water availability even when the engine is not running. The calorifier is constructed with a duplex stainless-steel inner tank and a stainless-steel (AISI 316) outer tank, offering excellent corrosion resistance and service life in marine environments. A 50 mm polyurethane foam insulation layer with a steel outer jacket minimizes heat loss and maintains water temperature for extended periods. The unit is supplied complete with a mounting kit, hose pillars, and a pressure relief valve for safe and efficient installation.
