Efficient heating
One thing off-grid solutions aren’t great at is running electrical heating. The heaters are energy intensive, they take a substantial chunk from the batteries just to warm up a small room. That’s challenging during winter when you need heating and sunny days are short.
A great solution to this is biodiesel heating.

Diesel heating
Diesel heaters have been around for decades but they're mostly used where a fuel tank is readily available such as a boat, lorry or camper van.
We've taken a hard look at them and discovered that they're exceptionally efficient, surprisingly clean, very cost effective and, if run on carbon neutral biodiesel, they're sustainable too.

Why the Hades biodiesel heater?
We've created an outdoor unit complete with fuel tank that can be hooked up to your room in no time, outputting a cosy 4.8kW of heat.
All this heating from as little as 18.9p* an hour for forecourt fuel or 9.3p for Kerosene!

You're in control
A simple touch screen based on the Ark's Bob character guides you through the heating process.
- Use the heater just as you would home central heating.
- Enable frost protection for rooms infrequently used.
- You can even set humidity controls to prevent condensation.
Bob intelligently calculates how quickly your room cools to maximise your fuel efficiency.'
Information
*Worst case cost of forecourt diesel is 18.9p per 100ml and electricity 28p/kWh at time of writing (20/05/26). Lowest diesel heater settings (100ml/hr or 1.2kWh) keeps an uninsulated wooden summer house room of 30m³ around 18°C with an outside temperature of 5°C. Highest diesel heater setting uses 340ml/hr or 4.8kWh. Heater tank size is 20 litres.
100ml/hr of fuel is 1.2kWh so equivalent electrical energy heating would cost 33p an hour vs 18.9p per hour for the biodiesel heater. Biodiesel heating is almost twice as cheap as electric with standard diesel. Kerosene is currently 93p a litre which makes it over 3.5 times cheaper than electricity!
Other fuels can be used such as red diesel, kerosene and biodiesel.
