In the above connection with the relevant page of my AutoSleepers guide reads as follows:-

"Note: if just the cold water system is being used, without the water heater, the heater tank is also filled up with water. In order to avoid damage through frost, the water contents must be drained by actuating the safety/drain valve and also when the heater has not been used. As an alternative, a shut-off value can be installed upstream of the cold and hot water connection (your AutoSleepers dealer will advise on this).

My question is if the cold water system is to be used in winter and the water heater is to be drained using the safety/drain valve does a shut-off valve also need to be installed bearing in mind it is referred to above "as an alternative".

Truma Ultrastore Water Heater - Frost Protect Empty Drain valve

Post by murph on Tue Nov 13, 2012 9:06 am

Hi Wearsider,
Ours has a drain valve fitted in the pipework between the tank and the pump to drain the heater, but this means you can not drain the heater without draining the whole system. As the heater is mounted inside the van even if it is full it shouldn't freeze if the van is in use as even if the space heating is off (unlikely,) the occupants body heat should be enough to prevent freezing except under very extreme conditions, and British built vans are not normally insulated to cope with alpine conditions.

Hi If I am using the van when it is freezing, just before hitting the sack, I turn the water heater on until it is fully heated, this stays hot all night, if not using the drain it fully.

Please read the following:

Another weird thing to do that actually works is, if you are going out into a cold environment without gloves on, it helps to wet your hands with cold water before you set out! up!

Enjoy. tap_fingers

All the responses above to my original posting are interesting and informative but none contain a definitive answer to the question that I posed which was:-

My question is if the cold water system is to be used in winter and the water heater is to be drained using the safety/drain valve does a shut-off valve also need to be installed bearing in mind it is referred to above "as an alternative".

Does every one else have a lagging kit or insulation jacket around their Truma Ultrastore water heater? I presume these are fitted by Auto-Sleepers when new? but could someone confirm as I would like to obtain a replacement as ours has tear in it which I've temporarily fixed with some gaffer tape until I can obtain another.

No, not on our 2002 Pollensa. As the water heater is installed under the rear facing bench seat, which becomes the bottom half of my bed, it keeps my tootsies warm at night so no problem. agree3

Hi CC
None around mine. Again located under rear bench seat. If we heat up on EHU for approx an hour prior to leaving site it stays pretty warm till end of day.

Thanks Boaby...

I was beginning to think I was the only one hugegrins
It had crossed my mind that the previous owner had fitted it, and was concerned that it might somehow get overheated if left on for long periods.
Seems to do it's job as water is still pretty hot the next morning when switched off during the evening.

Thanks Hoopman for your reply as well up!
