COMPACT INSULATED DIESEL HOT WATER AND AIR HEATING PACKAGE FOR MOTORHOMES, CARAVANS, OFF ROAD TRUCKS AND SMALL TO MEDIUM BOATS

The DH15 is Dieselheat’s most popular diesel hot water system, with super fast heat up time, the DH15 will provide a sink full of hot water or a shower at within 12min of a cold start.

The beautifully engineered D5E HS3 furnace from Eberspacher smoothly modulates it’s heat output from 1.3 to 5kW, so the DH15 works with a small coolant volume whilst avoiding excessive cycling. This minimises noise and power consumption making the system quiet and totally suitable for overnight air heating.

The DH15 is sold pre assembled and tested for easy installation. The kit includes the genuine Eberspacher installation kit with wiring, fuel line, exhaust, inlet air silencer and on/off switch.  The Eberspacher Easystart Pro controller can also be purchase separately.

Suits installations where the fan heater is within 1m of the hot water system and no more than 0.5m above it.
