RVs and BUSES | MARINE | OFF GRID – SOLAR | 240V | DIESEL | ENGINE
Dieselheat has developed a range of systems to create eco-friendly solar hot water by utilising surplus capacity in your existing solar system and then boosting with a diesel furnace when the sun isn’t shining or you need to run optional air heating.
Our systems use SureCal copper calorifiers (hot water tanks) and connect to your existing solar system, engine (for boats), diesel furnace or 240V when available to provide hot water and optional air heating in a space-efficient integrated system.

SureCal Tanks
The SureCal tanks imported from the UK by Dieselheat are a high quality copper tank with 2 hydronic heating coils and the option for dual electric elements, making them the most versatile tank on the market. In addition, the copper construction allows very efficient heat transfer from the diesel furnace to the water in the tank, ensuring rapid heating and minimising excessive diesel furnace cycling.
Solar
The system utilises excess capacity in your existing solar system to heat your hot water once your batteries are fully charged. This is done using a solar diverter to divert power from your solar panels when your batteries are charged. If your batteries start to drop, the diverters cut out the heating element ensuring your batteries remain fully charged. This system operates directly on your battery system at 12V/240V (combined), 12V or 24V.
Our solar electric heating options all heat at sensible power levels to keep current levels at or below 25A and assuming a decent solar system allow the 15L, 22L or 40L tanks to be fully heated on a typical sunny day.
Eberspacher D5E Diesel 5kW Power Pack
On days when your batteries do not fully charge, when you need extra hot water, the system can be heated using a diesel booster. The diesel booster can also be used to run optional hydronic air heating as well. For these systems, we use the premium Eberspacher D5E 1.3kW – 5kW hydronic furnace, the quietest and smoothest furnace on the market.

*Service intervals are based on manufacturers’ guides or our experience. They can vary significantly depending on fuel quality, dust ingress, and how furnaces are used.
240V Elements
The system can have an optional 240V element (combined with a 12v solar element) to allow heating when on mains power. This works well for RVs and boats when a mains connection is available.
Optional Air Heating
By adding an air heating head to your E-Solar system, you can turn it into an efficient air heater. It can deliver up to 5kW of heating through either Kalori or Dieselheat’s own ducted fan heads. These fan heaters can be installed remotely, offering flexibility in positioning for zone control and excellent heat distribution. Perfect for setups in caravans, RVs, or boats, this system provides an all in one combo for hot water and air.
Air Heating Thermostat
The Dieselheat Hydronic Thermostat pulls the hot water and air heating system together to act as one unit. It performs the following functions:
- Hot Water control: Switches hot water on/off.
- Air heater control: 3 manual speeds and automatic mode to control room temperature.
- Coolant control: Switches hot coolant on/off with fan heater, to minimise excess heat when air heating is not needed.
- Furnace control: Talks directly to the Eberspacher furnace to read/clear error codes, turn on high altitude mode.
How can I avoid wasting water on my van or boat?
Pair the DH Hydronic with our Specialised Shower Accessories for super water-wise showers (as low as 2L/min) with digital temperature control. We highly recommended this for caravans or boats where water is limited.
Low Flow Shower Heads
US made Bricor low flow shower heads provide excellent spray patterns at low flow rates giving a decent feeling water wise shower.
Digital Temperature Control Valves
Digital mixing valves allow a specific shower temperature to be set without needing to adjust a hot and cold tap. These work well for single pipe outdoor showers and deck showers on boats.
Warranty and Technical Support
All products in our E-Solar Series are backed by a two-year warranty. Not only this, at Dieselheat we pride ourselves on our excellent service, and we’re only a phone call away if you need professional advice. You will enjoy piping hot water, warmth and a good night’s sleep knowing that if you need help, we’ve got your back.
