I have searched but not come up with much :confused:

we have a '91 Frankia on a peugeot chassis, inboard fresh tank but underslung grey, I have a notion of using it for some ski trips so wonder what advice you can offer to make it more resistant to the cold,

and not just lagging pipes either, I read somewhere, maybe on ukcampsite, about using covers on fridge vents in the winter to stop draughts but not sure, understand this is bad when using gas but what about on 12/240?

thoughts please people

I can only speak from our own experience.
Our water tank is inboard under the dinette and we have never had any problems.
Our waste is under slung and when very very frosty we would leave the drain taps open with a bucket underneath and this has also worked for us.
We also have fridge winter covers which we do use when on gas or electricity. They do not cover the whole vent so some ventilation and some draft does still get in.
From memory (I may be wrong) but I think that in the fridge manual it states not to use then unless the temperature is below 7 degree. You could alwaye reduce this figure to about 2 or 3 degree.
Sometimes we may use them in the cooker department when the temp is above that figure if very windy, but we would then remove them when cooking.

The underslung grey water tank can be winterised by using insulation boarding, foil backed this prevents water ingress, cut to size and glued on using evostick, and finished off on the edges by ducting tape. Done this in the past with great effect, all supplies from B&Q. Remember to insulate the valve;)
Reminds me must do mine on this MH.
Happy Camping:)

interesting thought on the grey tank, thanks


and grath, don't worry, i'm not ignoring you ;)

Don't forget the Van itself, Get a decent battery and ensure the anti freeze is at the correct strength. I hear that the Russians use 100% antifreeze. Whenever I take vehicles into very cold places I also start the engine and run it until the temp guage gets to normal everyday, this helps to keep the battery conditioned and also helps to ensure the diesel does not wax in the tank. Its also a great way of warming up the whole vehicle a bit like lighting a fire in the lounge the heat from the exhaust pipe and engine seems to get everywhere.

Dont forget the snow chains, we have already had some snow and more forecast, you can wild camp here in La Chapelle and ski lift on the door step, good luck

Insulating a tank merely delays the inevitable. May be effective when the temperatures drop below freezing for a few hours, but if it is below freezing for more than a day, it is likely to freeze no matter how much insulation you use.

Quite right Tony, would not leave my grey water in the tank for more than a few hours, apart from the smell aspect the tanks on newish coach builds are not large enough to store the grey. Drain frequently is the answer.

...and if you have insulated the tank it will consequently take much longer to thaw out as well. The only failsafe way would be to introduce some kind of heat to the area, some manufacturers have ducted the blown air heating around the tank but I wouldn't think it would be an easy diy job.

The easiest method with an underslung grey tank in sub zero conditions is to leave the drain tap open and bung a bucket underneath. worse case scenario, its far easier to thaw out a bucket than a tank ;)

insulating the tank sounded like a good idea but what tony has said makes sense as does what peejay says....


think a bucket it is then :)

Agree, exactly what I said in my reply:D
easiest and safest:)


edit,
I put our winter covers on last night as our van is at home with water in the tank and more importantly in the pipes and boiler. Also put a small oil heater in last night as temperature was around freezing.
Next time we use her, I will drain everything down. A bit of a chore when you use it every couple of weeks, refilling & draining but at least I can sleep easy.
