A Malibu where the heater doesn't get warm while the boiler does, often points to a circulation problem or a valve fault.

A Malibu where the heater doesn't get warm while the boiler does, often points to a circulation problem or a valve fault. If there's no heat at all, the cause is usually an empty gas bottle, a faulty circuit board, a blocked burner, or a seized circulation pump. The cost of a diagnosis is typically between 50 and 120 euros, depending on the system and the workshop.
A cold Malibu is annoying, but often the cause is easy to find. Sometimes it's a matter of an empty gas bottle or a fuse, but equally there could be a more expensive fault with the burner or electronics. With a systematic approach, you'll usually find it quickly.
Malibu installs a Truma Combi heater in most campers, which runs on gas or diesel. In the more expensive models, such as the Malibu Van or the larger integral models, an Alde central heating system with water circulation is sometimes used. Each system has its own typical quirks, but the diagnosis always starts with the basics.
First, check whether there is sufficient gas or diesel and whether the power supply is in order. An empty gas bottle or a faulty fuse is quickly resolved. Then check whether the thermostat is set correctly and whether the clock is not accidentally set to 'off'. If the fan is running but no warm air is coming out, the burner may be blocked or the ignition may be faulty.

The costs depend on the fault. A simple cleaning or a new fuse costs a few tens of euros. A new circuit board or burner for a Truma Combi can amount to 500 to 800 euros, including labour. For an Alde system, a new circulation pump is often around 300 to 500 euros. Always have a diagnosis carried out before making major expenses.
