Diesel Heater Exhaust Insulation

Keep Your Camper, Caravan or RV Safe with Kool Wrap Heat Insulation

Diesel heaters are a popular choice for heating caravans, campervans, tiny homes, boats, and off-grid mobile setups. However, the exhaust system in these heaters can generate extreme temperatures, especially when routed through confined areas like cupboards, underfloor sections, or cabinetry. 

Without proper insulation, the exhaust pipe from a diesel heater can become a serious fire hazard—scorching timber panels, melting insulation foam, or damaging surrounding furnishings. That’s where Kool Wrap’s Diesel Heater Exhaust Insulation Wrap comes in. 

Crafted from heat-treated fibreglass, our insulation wraps are specially designed to contain and reduce radiant heat, creating a safer and more efficient environment for your heating setup. Whether you’re a DIY installer or a caravan technician, Kool Wrap provides professional-grade protection you can trust.

Why Diesel Heater Pipe Insulation Is Essential

The flexible metal exhaust pipe in diesel heating systems can reach temperatures well over 300°C during normal operation. When installed in close proximity to wooden floors, plastic panels, foam insulation, or cabinetry, this radiant heat can cause: 

  • Discolouration or warping of materials 
  • Melting or degradation of insulation 
  • Increased risk of accidental fires 
  • Reduced performance due to heat loss 

By wrapping the pipe in high-temperature exhaust insulation, you minimise these risks while improving heat retention and fuel efficiency. It’s a smart investment for both safety and comfort.
