    Hi, we have the Truma heating system fitted with optional electric, gas and or diesel fuel. It takes an age to warm up up on electric only, is this normal? Any advice on the best way to get warm air sooner would be much appreciated.

    Thanks

    Electric will always be slow because of the limited power draw of the element. EHUs won't support the size of element needed to heat a van in really cold weather. Take a look at the rated output on gas then compare it with the electric element. Fast warm-up is achieved by running on electric & gas together. Once warmed through it's usually possible to run on electric on its own.

    My combi 6E takes a fair while to warm up on Electric only, but I also have a boost when the set temp and room temp are 10 degs different. If I need heat quickly, I use combo of Elec and Gas. This gets MH warm in 20 - 30mins with full fan on. If out for the day, I use programmed timer.

    Flash it on gas and electric then go electric only to maintain ambient temperature. Should be good down to around 5C outside.

    If you want fast heat, set it to Mix fuel, then when its warm set to electric 2. Electric 1 is only good for hot water in summer.

    Thank you all for the advice. Flashed it up on mixed and it came alive! Fan speed an heat increased quite quickly.

    On another note the fridge freezer switched itself onto gas last night. Had power to everything and wasn't drawing much at all. When I dropped the fridge temp down one notch it went back on to electric. Is that normal? Thanks again

    Fridges ( esp Thetford ones ) are very sensitive to mains voltage drop..
    Happens all the time to me on big sites in far off countries
