Having recently bought a new Motorhome (Eldiss Autoquest) we have found the blown air heating system less usable than our old caravan fire.
The old fire could be left on at a low gas overnight during the winter cold and it kept the van reasonably warm/comfortable.
The problem with the blown air system is that when running on just gas and 12v battery the battery can't cope with long periods (7-8hrs) overnight operation without the battery dropping voltage to a level where heating and hot water systems lockout.
No problem on electric hookup but we often rally 'Off Grid'.
The motorhome has a 100W solar panel on the roof but not sure it can cope with dull winter days enough to charge the leisure battery. Has anyone come up with a solution to this? I am thinking of buying a second leisure battery as a standby.
Hi JH. I have been using caravans & Motorhomes for 25 years on Rally fields CLs and CSs .I would always have a second battery to harvest the energy provided by solar.Before Solar Panels we carried a spare leisure battery on 3 day rallies.
I agree that the older gas fire plus blown air is easier on battery,I do not like the modern Combi system..The other thing to consider on cold dark days is Television use ensure you have a low amp TV.
we never use the blown air if not hooked up, well we did once and the battery was flat by day 2 of a 3 day rally, we just use the gas fire on its own, ok in the winter months it takes longer to get things warmed thr but just open every cupboard and lift the fixed bed up to remove the cold air but once warmed up the gas on its own is more than enough
secong or even third battery if youre speonding so much time off EHU and not travelling around. also consider b2b so leiasure batteries will charge when driving

Fit an additional leisure battery , we have 2 x 110 amp batteries and 2 x 120 watt solar and can have the TV on in the evenings as well as the Truma Combi boiler gas heating overnight if necessary without running out of power
Unfortunately the modern system in this motorhome doesn't allow that option. It is a case of heating on and blown air also. I have come to the conclusion that like others I will need to carry a spare battery.
Couldn’t agree more. Blown air combi boilers are rubbish. Rarely use sites with EHU and I do quite a lot of steam rallies. So no EHU for at least four days at a time. I have two leisure batteries and a 150 watt solar panel. But as I watch a lot of TV and like a light on. The batteries will only let the heating be on at the same time for short time before the control panel for the heater starts flashing red low voltage.This also has the effect that the gas igniter and gas valve is slow to operate so the heater pops as the gas is trying to light. ( before it is suggested that it needs servicing. I am a gas engineer. In normal solo operation when full power available the heater works fine.) The old carver blown air heating with the stand alone fire front and a separate water heater was a far superior system. Sorry Truma but you got the combi boiler so wrong. If only I knew then what I know now I probably would have bought a different motorhome. Something for others to consider. 🤔🤔🤔
I have a 2016 chausson 628 eb motorhome,the diesel/electric Truma heater is nothing but trouble.when van was 18 months old and wintering in southern Spain the diesel side of the boiler packed in ,on returning to the uk the dealership I bought it from said it was the glow plug which was changed same thing append again almost immediately ,new glow plug fitted (must be a bad batch) this time a new fuel pump was fitted .all well for about a year then just before Xmas (2019) all heating packed in (diesel and electric )local dealer looking at the problem this time .if has had to be sent to Truma who it seems have managed to get the electric side of things going they seem to think it’s the guess what the glow plug again ,any one out there with any ideas
