They are easy to install and use, and can provide a consistent source of warmth even in the coldest of temperatures. With a range of sizes and styles available, diesel heaters are a great option for anyone looking to stay warm and comfortable in their living space.

Frequently Asked Questions (FAQs)
1. Are diesel heaters safe?
Diesel heaters are widely used and considered to be very safe. They include an auto-shutdown if the system temperature exceeds a safe operating level, the same as LPG heaters.
2. Can a diesel heater heat a house?
Even if you have a wood fire, a diesel heater can still be handy for quickly heating up your home when you arrive late at night and don't want to start a fire, or can be left on a low setting to keep things warm overnight.
3. How long will a diesel heater run on a tank of fuel?
The diesel heater features an oil pump that precisely controls the fuel inlet for thorough combustion, saving energy while working smoothly. A full 10L/2.6 gal fuel tank will power your heater for up to 100 hours, ensuring low emissions and long-term running.
4. Are Chinese diesel heaters worth it?
However, the Chinese heaters tend to get a bad reputation for reliability, parts availability and, most importantly, safety. Chris Emmerson of CJE Caravan Repairs has seen a lot of dodgy products come through his workshop, but increasingly he is being asked to fix issues associated with cheap ducted diesel heaters.
