Do I switch the moho heating on

[Jewellbags]

Off tomorrow for a few days and water is in the tank etc (tank is within the body shell) . I have a small electric rad running tonight just in case. Think that’s enough or should I switch on the diesel heater ? -4 forecast

Can you not put the van heating on electric or do you only have a diesel heater.

Diesel only but TBH it’s very efficient IMO and when I’m away it’ll be on 24/7 in tick over

I would say the rad is enough.
May be -4°c outside but well above freezing inside.
Only thing you may have to watch is the water dump valve.
They don't appear to have a consistent dump temperature.
