The Dometic TwinBoost 6000 is a highly efficient 2-in-1 gas heater designed to provide both cabin heating and water heating for motorhomes and caravans. With its innovative dual-chamber design, it allows air and water to be heated directly and independently, ensuring that warm water can be accessed in summer without the need to heat the cabin. This flexibility makes the Dometic TwinBoost 6000 an ideal choice for all-season use, delivering comfort and efficiency for both short trips and extended stays.

Offering an impressive 6000 W heating capacity, the Dometic TwinBoost 6000 quickly warms cabin spaces on colder days, ensuring a comfortable environment no matter the season. The integrated 10-litre water tank, powered by direct heating technology, delivers ultra-fast hot water performance, providing ample water supply for showers and other daily needs. With four warm air outlets, the heater ensures consistent and even heat distribution throughout the living space for maximum comfort.

The Dometic TwinBoost 6000 features an intuitive control panel that offers advanced programming options for a customised heating experience. Users can save their favourite settings for quick and efficient operation, while the easy-to-read display ensures precise adjustments with minimal effort. Additional functionality, such as the cabin vent mode, allows for ventilation without engaging the air heater, further enhancing energy efficiency. The smart chimney cover design and 3-in-1 safety system ensure safe and reliable operation at all times.

Designed for motorhome and caravan owners who value performance and energy efficiency, the Dometic TwinBoost 6000 combines power, functionality, and convenience in a compact and reliable unit. Whether warming the cabin on chilly mornings or delivering fast hot water for daily needs, it is a versatile solution for modern travellers.

This compact gas heater has two separate heating chambers, one for cabin air and one for warm water. The unique dual-chamber design allows superior performance, because air and water are heated directly and independently of each other. No need to heat the cabin just to get warm water. Enjoy an impressive warm water performance in summer, or an ample 6000 W capacity to get your cabin warm on a chilly day!

Energy-saving heater
Energy-saving heater
Dometic TwinBoost combo heaters make very economic use of energy. Instead of keeping the heater on all day, simply set the time for how long you want your water to be warm. And there's no need to heat the cabin air to get warm water either. Save energy and money while enhancing the comfort of your motorhome!

Get the water hot more quickly
Dometic TwinBoost combo heaters feature a unique dual-chamber design, with separate heat chambers for cabin air and hot water. A unique benefit of the technology is that the water tank is heated directly – and not indirectly via the air heating as with other combo heaters available in the market. This results in a super-fast water heat-up with minimal energy loss.
