COMPACT INSULATED DIESEL HOT WATER FOR MOTORHOMES, CARAVANS, OFF ROAD TRUCKS AND SMALL TO MEDIUM BOATS
The DH15 replaces the DH12, 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 continuous shower at 2.5L/min within 9-10 min of a cold start.
The beautifully engineered D5E HS3 furnace from Eberspacher modulates it’s heat output from 1.3 to 5kW, so the DH15 works with a small coolant volume whilst avoiding excessive cycling, this also minimizes noise and power consumption.
The DH15 has the following features
- All 316 stainless steel, suitable for caravans and boats
- Insulated dual skin tank retains heat for efficient operation
- Compact design fits in tight spaces
- Pre assembled and tested for easy installation
- Fast heat up time, around 9-10min from cold
- Integrated air heating (optional)
- Includes Watermark approved tempering valve and plate heat exchanger to ensure hot water is always delivered at safe temperatures
Pair the DH15 with a Bricor Ultra Max low flow shower head to have super water wise showers – 0nly 2.5L/min, great for a caravan or boat where water is limited. Alternatively use the Bricor Elite shower head for a more luxurious 4-5L/min shower.
By adding in a hydronic fan head you can turn your diesel hydronic hot water system into a quite and effective air heater. See here for information on choosing hydronic fan heaters or see here for our pre packaged hot water and air heating combo systems.
The advantages of the brand new Eberspacher D5E HS3 Furnace include:
- much quieter in terms of the combustion fan and overall noise
- uses the new Eberspacher super quiet fuel pump (no ticking sound)
- drops to low power much faster, so re-starts are much gentler and quieter
- longer service life – 3000 hours is claimed
- stepless power output from 1.3 to 5kW
- when using fan heads for air heating, as long as the fan head is dissipating over 1.3kW it won’t cycle at all, and at low power it is as quiet as an air heater
- soft start water pump that primes more easily
- improved water and dust resistance
- excellent installation kit
System Performance
Time to useable hot water from cold start: 9min
Time to fully hot: 14min
Regeneration time between showers: 7min
Length of shower assuming 30 degree temp rise using Dieselheat shower heads:
Bricor UltraMax 2.5L/min @ 40PSI: >15min
Bricor Elite 4L/min @ 40PSI: 7min
Length of time the system can achieve a 30 deg temperature rise:
2L/min – >15min
3L/min – 13min
4L/min – 6min
5L/min – 3 min
These numbers are all affected by ambient temperature, installation layout and assume no concurrent air heating, so should be taken as a guide.
Assembled System Includes
- insulated 15L hot coolant tank
- Eberspacher D5E HS3 diesel hydronic furnace
- mounting bracket
- combustion air silencer and exhaust system
- silicon exhaust floor plate
- tempering valve

Notes
- The system is not shipped with a controller which is required for diagnostics. See the Eberspacher Easystart Pro or Dieselheat Hydronic Thermostat V3 for controller options.
- The system is not shipped with coolant. The purchaser is required to fill the tank using a standard automotive coolant mix.
