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 Diesel Heater you'll enjoy the comforts of home when you embark on your next adventure. Set the timer on the integrated 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 slimline all-in-one design of this Thermomate model sees the fuel tank and heater combined together in a metal case. This allows for straightforward installation by anyone handy within the interior of vehicles, or for neat placement in a workshop. It's also much simpler in the event that you want to remove it before selling your vehicle.

The Thermomate provides up to 18 hours of operation, and is the best way to heat vehicles when parking without any need to run the engine, saving on fuel and unnecessary wear and tear. And when you're done, the automatic cooling cycle quickly brings the unit back to room temperature. Make the smart investment in your comfort and trust Thermomate for your portable heating needs.
