The Ultimate Guide to Diesel Heater Installation for Campervans

Why Every Campervan Needs a Diesel Heater

If you’ve ever shivered through a night in your campervan, you’ll know how crucial reliable heating is. A diesel heater installation transforms your van into a year-round adventure machine, providing instant warmth even in sub-zero temperatures. At Kinmel Campers, we’ve fitted hundreds of 8kW diesel heaters across North Wales, from VW Transporters to Toyota Alphards, ensuring our customers stay toasty off-grid or on campsites.

Benefits of a Diesel Night Heater

✅ Instant Heat – No more waiting for a fan heater to warm up.
✅ Energy Efficient – Runs on your van’s diesel supply or a separate tank.
✅ Whisper-Quiet – Modern systems are nearly silent (unlike rattly gas heaters).
✅ Off-Grid Ready – Perfect for wild camping in Snowdonia or coastal trips.

We offer two professional installation options to suit your van:

1. Under-Seat Installation

  • Stealthy & Space-Saving – Ideal for smaller vans like VW T6s or Nissan Elgrands.

2. Custom External Welded Box
