If you’re looking for an effective, user-friendly heating solution for your vehicle, boat or workshop, then diesel heating is cost-effective, efficient and safe compared to LPG alternatives. Therefore, the real question is which Diesel Air Heater to go for? The reality is that no two models on the market are created equal. Thermomate is a step above the rest, being based on a proven German design and manufactured in a high-tech facility specialising in mobile heating for decades.

With a Thermomate 12V/24V Diesel Heater you’ll enjoy the comforts of home when you embark on your next adventure. Set the timer on the LCD Control Panel to ensure a warm cabin for when you wake up and cook breakfast, or have a lazy morning and adjust the temperature from bed with the remote control. The Thermomate will take care of smooth, automatic room temperature control with continuous monitoring and diagnostics. 

The Thermomate offers powerful, efficient performance thanks to a unique heatsink design that is cast from premium 1050 grade aluminum offering superior thermal conductivity. Whether you’re in a caravan, motorhome, camper trailer, truck or boat your space will be toasty in no time, and any frost on windows will quickly disappear. Once the target temperature is reached, the Thermomate is surprisingly quiet, so you’ll have happy campers and everyone will enjoy a good night’s sleep. 

The Thermomate can run from the supplied 10L tank which provides up to 36 hours of operation, or you can conveniently link up to an existing diesel fuel line. The Thermomate is the best way to heat vehicles when parking without any need to run the engine. And when you’re done, the automatic cooling cycle quickly brings the unit back to room temperature

The compact design allows for easy and space-saving installation within the interior, or even under the floor of vehicles. The Thermomate Diesel Heater comes complete with all accessories you need, making it possible for anyone handy to install. Make the smart investment in your comfort and trust Thermomate for your portable heating needs.
