Truma Combi 4E Plus Water/Air Heater – Installation Kit Included is a smart, space-saving solution that blends powerful space heating with reliable hot water, all in a single compact appliance. Designed for caravans, motorhomes and campervans, this unit Heat-and-Heat combo delivers warmth in minutes and provides the hot water you need for showers, dishes, and hands-free cleaning without the clutter of two separate systems.

Why carry two bulky systems when you can have one efficient, versatile unit? The Truma Combi 4E Plus combines space heating and water heating in a single installation, freeing up precious vehicle space and reducing weight. Its 4000 W gas heat output and integrated electric elements mean you can tailor heating to your power availability and climate, staying comfortable whether you’re plugged in at a campsite or cruising off-grid. The system is designed for quick response, so your vehicle reaches a cozy temperature in minutes.

Key benefits that matter on the road

• All-in-one comfort – Heats the living space and provides hot water from the same compact unit, simplifying installation and reducing maintenance. This streamlined approach is ideal for smaller vehicles where every inch counts.
• Multiple heat sources, flexible operation – LPG (gas) and electricity options give you reliable warmth whether you’re connected to mains power or relying on LPG. The system supports gas, electric, and mixed modes to balance performance with energy use.
• Fast, efficient heating – The 4000 W gas heater, combined with electric heating elements, delivers rapid warmth and hot water. Water heating from 15°C to about 60°C typically takes around 23 minutes for water alone, and the full heater-plus-water package completes in roughly 80 minutes, depending on conditions.
• Precise climate control – A digital CP Plus control panel (iNet-ready) lets you effortlessly set room and water temperatures for personalized comfort, with easy monitoring and programming.
• Low energy, high efficiency – Optimized energy use with thoughtful electrical loads means you stay warm without draining your battery. Peak electrical consumption is clearly defined for both 12 V operation and mains power.
• Smart frost protection – Frost Control automatically empties the water tank in freezing conditions, helping protect the system and simplify winter storage.
