We bought our van in Jan this year and left it empty and drained until first use in March. Have to admit when the exceptionally hard frosts were on I put a convector heater in there 'just in case'.
This year we intend using it once a month over winter and so don't want to empty it out. I've hooked it up to mains and set the Eberspacher heater on to 'Frost'. Fresh and waste tanks drained but not the blue 'pump tank' or whatever it's called, so as to allow the heater to work. Looking at the max/min thermometer I have in there [with an external sensor ziptied to the bike rack...] it was 36 outside and 42 inside last night. Today I've opened all cupboard doors and upended the seat cushions to allow for airflow. Will this be enough? Or do I have to empty everything out? And if anyone has a similar heater, I'd be curious about the likely cost over winter!
