The Dometic TwinBoost 6000H is an advanced 2-in-1 gas and electric heater designed for motorhomes and caravans, offering both cabin air heating and water heating. The “H” in the title signifies its hybrid capability, enabling operation on gas, electric, or a combination of both power sources for superior efficiency and flexibility. Its innovative dual-chamber design heats air and water directly and independently, allowing users to access warm water without heating the cabin – a key benefit during summer months.

With an impressive 5800 W cabin heating capacity, the Dometic TwinBoost 6000H ensures reliable warmth on chilly days, creating a comfortable environment for year-round travel. The integrated 10-litre hot water tank benefits from a generous 3800 W capacity when running on electric power, delivering ultra-fast water heat-up for showers or washing. This hybrid system ensures consistent performance while offering energy-saving benefits by enabling independent air and water heating. Four warm air outlets provide even heat distribution throughout the living space, enhancing comfort.

The Dometic TwinBoost 6000H is equipped with a user-friendly smart control panel that offers multiple programming options, allowing users to tailor the heating experience to their specific needs. Favourite settings can be saved for quick and convenient access, while the easy-to-read display simplifies operation. Additional features, such as the cabin vent mode, provide ventilation without activating the air heater, helping conserve energy. The 3-in-1 safety system and smart chimney cover design ensure safe and efficient performance.

Ideal for motorhome and caravan owners seeking a reliable and flexible heating solution, the Dometic TwinBoost 6000H combines powerful gas heating with electric efficiency. Its hybrid functionality, independent operation, and flawless integrated design make it an excellent choice for travellers who demand comfort, convenience, and performance.

This compact gas/electric heater has two separate heating chambers, one for cabin air and one for warm water. The unique dual-chamber design allows superior performance, as 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 5800 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.
