Keeping the heating on over winter?

[Swamp]

We’ve just got back from a few days away in the van and while the weather hasn’t yet turned properly cold I was thinking through the steps I need to take for when it does.
Our van is used every couple of weeks over winter and while parked up is at home with access to hook-up. I found myself wondering today whether it made any sense to leave the Truma heating on very low (maybe 5 degrees) to keep things from freezing and, hopefully reduce condensation.
It maybe a completely crazy idea so I would appreciate your thoughts?

Ne sense leaving heating on, wears heating out and causes damp.

I am sure you will get some funsters saying yes, it is a crazy idea.

But, I think not and our heating is always on over the winter months. and has been for decades.

No. leaving the heating on does not cause damp. Just the opposite. Our motorhome is always warm and dry, ready for use.

What age is your van and was it built winterised

If it's on low and saves draining down when it gets cold that's OK in my book Lazy not Crazy

It needs aired not heat. Heating causes condensation which if not dried daily will do more harm than good .

It may save the draining down etc but no van is immune from condensation

On our last van we did this for about 8 years out of the 10 we owned it.
Only needed a repair to the control board that I did myself for £1.50 and a water pump that was £116 (Alde wet system) and only stopped doing it due to the high electric prices.
Lovely to have it warm ready to go though

Agreed but 5 degrees as mentioned is hardly tropical OK might be for a Scot but not me

Nothing wrong with protecting you van from frost.
But a dehumidifier would be a good idea

If your going to live in the van it's a good idea. If it's just parked up it's not necessary , winterise the van then go out and open the doors and sky lights whenever it's dry.

Heating only highlights condensation if the 'van is already damp inside.

In which case , the answer is to cure the cause of the damp.

Contrary to the popular myth, heat does not create moisture.

Rather than use the van heating system I'd get a simple electric oil filled domestic radiator and set it for 5c or whatever

Condensation only forms where heat meets cold. A van that is the same temperature inside as outside will stay dry when uninhabited unless there is a leak. Truma will tell you that their products are not designed for regular use. Also the electric elements are prone to failure in normal use.

I keep our Alde heating at 5 degrees. No condensation and pleasant to use.

 

[Gromett]

Heating only causes condensation if the heated air comes into contact with cold surfaces. If the van is permantly kept above the condensation temperature point then there are no cold surfaces for it to condense on.

I have been a fulltimer for 15 years and keep the heating on all the time during the winter. The only place I have ever seen condensation is in the cab area. I keep that partitioned off from the hab area and I never saw any at all.

You’re already doing the best thing possible and that’s using it regularly over the winter period

 

[Riverbankannie]

A lot depends on your van. Our old autosleeper with the gel roof on top of the T4 van never suffered from condensation whereas our current Ducato with poor insulation, every morning even now has the mirrors inside running but not the windows.
I am talking about when parked up.
I think the metal van heats up inside in the sun and then the temperature drops.
So my solution, that works for my van, is to leave a small fan heater on frost setting but that means using EHU. I wouldn’t want to leave the Truma on.

The Truma heating system is built into the fabic of the van and as such will keep all the water pipes,etc and everything else in there at the right temperature.

Why?

I thought the alde heating systems (at least) had a set back you could change manually to come on when the temperature hits the low temp specified.

Surely this would do a better job at protecting the vulnerable bits than having an oil fired rad running in the body of the mh?
