Isotemp Slim Stainless Steel Water Heater 20L - 135692
20L slim stainless steel marine water heater
Isotemp Stainless Steel Marine Water Heaters
The Isotemp Basic range by Isotherm® delivers reliable onboard hot water using a combination of shore power and engine heat recovery. Designed specifically for marine applications, these premium water heaters utilise both a 240V immersion heater and an integrated heat exchanger, allowing hot water to be generated from either mains power or the vessel's engine cooling system.
Constructed using high-grade AISI 316 stainless steel for all water-contact surfaces, Isotemp water heaters provide outstanding corrosion resistance and long service life. The internal tank is insulated with expanded polyurethane foam to minimise heat loss and maximise energy efficiency, while the brushed stainless steel outer casing provides a clean, professional appearance.
An extra-long heat exchanger coil delivers rapid heating from the engine cooling circuit, making the system particularly effective for yachts and motor vessels where engine run times may be limited. Carefully positioned water inlets and outlets help minimise mixing of incoming cold water, ensuring maximum hot water availability throughout the tank.
The adjustable mounting brackets rotate through 360 degrees, allowing installation in either horizontal or vertical orientations to suit available onboard space. Available in Slim and Basic configurations with capacities from 20 to 75 litres, the Isotemp range provides a solution for a wide variety of vessel sizes and hot water requirements.
