    Truma Combi 4E Water / Air Heater & Flue Kit

    Product Details


    The Truma Combi 4E Water & Air Heater is an intelligent dual purpose machine designed to provide you with uninterrupted heating and hot water on your next road trip. The Truma Combi 4E gas powered air and water heater is an innovative product that can cater to heating both air and water simultaneously and independently. Powered by liquid gas and operating on 12 volts, the system can generate up to 4000 watts of heat. All this while remaining environment friendly thanks to its 97% energy efficiency rating.

    The functions of the Combi 4E are accessed via an LCD control panel, programmed for user-friendly operation. The appliance comes with a stainless steel 10 litre water tank which is both weatherproof and leakage resistant. It heats water in as little as 20 minutes, (90 minutes with the air heater operational), with the additional ability to mix and heat water while you shower. The product is equipped with performance enhancing features including a safety sensor, self-draining mechanism and anti-frost technology. The system is ducted (65mm ducting to be purchased separately), and comes with three outlet vents. Despite its high performance rating, the Combi 4E range is highly conservative in its fuel consumption, and minimal in its weight and dimensions. This maintenance-free dual purpose air and water heater is the ultimate companion for a state-of-the-art motor home.

    One device delivering two functions being able to enjoy double the comfort in your motorhome or caravan.  The Truma Combi 4E enabling you to heat the internal of your vehicle and heat your water at the same time is why the Truma Combi 4E is one of the most efficient space saving heater and hot water combo units on the RV market today.

    NOTE: the gas connection must be installed and completed by a licenced gas fitter.
