What size do I need? 
A diesel heater should heat your space quickly and efficiently. Once your temperature has been reached the heater fan will automatically slow down to maintain your set temperature. Leaving you in a wonderfully warm, quiet and dry environment all year round. If you choose a heater that is too small you will be left in a cold, noisy and damp environment as temperatures drop

Digital Controller
Simple wall-mounted digital controller displays everything you need to know. A real-time set temperature, actual temperature, animated blower fan, fuel pump, voltage and glow plug. 

Other controllers without a real-time display make it difficult to see what's happening when you have run out of fuel or have a low battery. This can be especially frustrating when it's cold and you need answers fast

  • Automatic. Set and forget. Fully automatic temperature control
  • Manual temperature control. Manually set the temperature for full control
