The Truma Combi D6 is a premium diesel-powered combi heater and hot water system engineered for caravans, motorhomes, and RVs — delivering up to 6,000 watts of space heating alongside a 10-litre hot water boiler in a single, compact unit. Running entirely on diesel fuel with 12V DC power, it operates independently of LPG, making it ideally suited to Australian conditions where diesel-fuelled rigs are the norm. The Combi D6 heats your van rapidly and quietly, producing warm air through up to four air outlets while simultaneously warming your water supply, so you arrive at camp — whether in the Australian Alps, the Kimberley, or the Snowy Mountains — ready to shower within minutes of switching it on.

Designed for year-round touring by caravanners, grey nomads, and 4WD adventurers who demand reliability in remote and off-road Australia, the Combi D6 performs in temperatures as low as -20°C. Its compact form factor allows straightforward installation into existing Truma ducted air systems, and it is fully compatible with the Truma iNet X panel for intuitive, app-based control from your smartphone. Whether you're chasing winter breaks on the Great Ocean Road, tackling the Gibb River Road, or setting up camp on the Nullarbor, this system ensures your motorhome or caravan maintains comfortable living temperatures without draining your LPG supply.

Lightweight and compact

Despite the ability to operate as both a space heater and hot water boiler, the Combi D6 is extremely small and lightweight. Featuring a 10 litre water tank, it can provide enough water for day-to-day tasks such as washing hands and dishes and even a quick shower as well as heating your living space.

Flexibility to suit your needs

With optimum air distribution through four warm air outlets and easy temperature adjustment via the digital control panel, the Combi D6 also allows you complete control over function at any moment, giving you easily changeable options between hot air, hot water or even having both at once.

Common questions about Truma Combi D6 Diesel Combi Heater and Hot Water System – Black

How much diesel will it get through overnight?

Around 0.65 L/hr flat out, and it rarely runs flat out. It modulates down to 1,000W once the van is warm, so a cold night is nothing like that figure multiplied by the hours. Budget conservatively and you will still be surprised how little it uses.

Will it cope in the snow?

It is rated to work down to -20°C, so the unit is not the weak link — your fuel is. Standard diesel starts waxing near freezing, so fill up locally when you head to the alpine country and run what the servos there are selling.

Do I need all four air outlets?

Use as many as your layout allows. One outlet dumping 6,000W into a corner makes a hot spot and a cold far end; spreading the flow across the van is what makes it comfortable. Plan the duct runs before the unit goes in, not after.
