Combi 4 E boiler - winter heating

yes, you can use the heater (on electric, gas or mixed) with the boiler drained...

i don't know if you have the CP Plus contol panel (black rectangle) or the twin knob system...

with the CP plus, it's pretty easy, just turn hot water to off.....and use heating with temp/fan control as you would normally.

with the twin dial system it's a little more 'tricky' but I'll only get into this if that's what controls you have...

nice van by the way....

As an aside, can you blow cold air (fan only) using the CP Plus control?

My twin dial system won't allow it but it could be upgraded if the CP Plus can.

Yes you can it has been very "helpful" in the summer heat this year

Oh, so an upgrade might allow it 

Cheers 👍

Thanks for clarifying and for the compliment, it's our first van and we're looking forward to testing it out  It's the dual dial control - which I think I've worked out but any tips welcome. 

 but any tips welcome

Yes, you can't blow cool air on nice hot days with dual dial control 

It takes a while on electric to get up to blowing some worthwhile heat but add a bit of gas and the time is cut down considerably.

Just had mine on in the van this morning as we were making the bed in readiness for our next trip. You have obviously discovered the setting, which is one down from the middle/off position. We use it regularly over winter to air the van between trips away.

Thanks! I'm assuming the gas/electric mix is achieved automatically?  Can you use gas without electricity - for example, off-grid/without hook-up, as I'm guessing the leisure battery would drain quite quickly if you didn't (you can tell I'm new to all this!) ? 

Good tip, thanks

Yes you can select gas only, electric only or a combination of both, this is the fastest way to heat the van from cold. The gas will go off once the van is up to temp and then be maintained by the electric. The heater works of mains 240v, however the fan is 12v.
