SUPER COMPACT DIESEL HOT WATER FOR SMALL BOATS WHERE SPACE IS TIGHT
The DH9 is Dieselheat’s smallest and most versatile diesel hot water system, with super fast heat up time, the DH9 will provide a sink full of hot water or a continuous shower at 2.5L/min within 6-7 min of a cold start whilst occupying a space the size of a couple of shoe boxes.
The beautifully engineered D5E HS3 furnace from Eberspacher modulates it’s heat output from 1.3 to 5kW, so the DH9 can work with a small coolant volume whilst avoiding excessive cycling, this also minimizes noise and power consumption.
The DH9 is sold assembled with the tank and furnace back to back on an aluminum mounting stand for easy installation and suits small spaces.
The DH9 has the following features
- Our most compact hydronic system
- Fully assembled and tested for quick easy install
- All 316 stainless steel, suitable for caravans and boats
- Fast heat up time, around 7min from cold
- Integrated air heating (optional)
- Includes 2m high quality lagged and insulated marine exhaust system with skin fitting
- Includes Watermark approved tempering valve and plate heat exchanger to ensure hot water is always delivered at safe temperatures
Pair the DH9 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.
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
DH9 System Performance
Time to useable hot water from cold start: 6-7min
Time to fully hot: 9-10min
Regeneration time between showers: 4min
Length of shower assuming 30 degree temp rise using Dieselheat shower heads:
Bricor UltraMax 2.5L/min @ 40PSI: >15min (recommended shower head)
Bricor Elite 4L/min @ 40PSI: 4.5min (pushing the limits, better to use a DH15 for this shower head)
Length of time the system can achieve a 30 deg temperature rise:
2L/min – >15min
3L/min – 9min
4L/min – 3.5min
5L/min – 2 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
- compact 9L hot coolant tank
- mounting bracket
- Eberspacher diesel hot water furnace
- combustion air silencer
- marine exhaust system
- tempering valve
- wiring loom with on/off switch
- fuel pump and fuel line
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.
Pair the DH9Duo with our range of water efficient shower heads or digital temperature mixing valves.
