Vetus WHT050 50-Litre Twin Coil Marine Water Boiler – Technical Specifications
The Vetus WHT050 is a 50-litre twin coil marine calorifier engineered to deliver reliable onboard hot water. It heats water by recovering surplus heat from the vessel’s engine via a spiral tube, while an additional coil allows integration with an onboard heating system for greater versatility. A built-in 230V / 1500W electric heating element ensures hot water availability even when the engine is not running. The boiler’s duplex stainless-steel inner tank offers excellent corrosion resistance, while the AISI 316 stainless-steel outer tank provides robust external protection. A 50 mm polyurethane foam insulation layer with a painted steel jacket minimizes heat loss. Supplied with sturdy mounting brackets and a complete fitting kit, the WHT050 is designed for quick and safe installation.
