Anyone any good with Truma water heaters?

[dirty_dog]

Hi all,
We are trying to get the water heater fixed on my parents van as we are going away this week.

The heater is a Truma Ultrastore Rapid and the water does actually get hot, initially. When left for a while the water seems to syphon back through the overflow on the tank which then drains itself. I assume this causes the element to over heat so it cuts out until you reset the power on the van.

A new tap and anti syphon device were both fitted on Saturday but its still cutting out.

Any ideas?

Thanks

Is the over wintering drain valve still open?

Will check it out, I hope not! It takes a while to empty out rather than quickly draining but will double check.
Cheers

It isn't that quick - it took all night to drain our Adria's water system from pretty much full....

You say it had a new tap and anti syphon device fitted, is it still ditching water after these? Or is it only cutting out? If its cutting out / red light on the dial after a short while then its getting too hot / tank has expanded from freezing.

Is it ditching water from the red outlet hose on the boiler its self?

Thanks guys I'll check tomorrow. Its still losing water after the new tap and anti syphon. I'm looking tomorrow as its my Dads van and he has done all the work so far so I'll try and do some troubleshooting too.
I'm sure last time I used it we were getting the red light on the dial all the time so I'll check this again.

Checked the drain and it seemed fine. As soon as the tank is primed and heated it starts to come out of the overflow which has already been changed for new.
Spoke to an engineer at Truma and they have diagnosed a faulty element, I guess this has an integrated thermostat which is what we wondered about initially.
Part is being collected tomorrow so we'll see.

speak to gary at arc systems http://www.arcsystems.biz/ what he doesnt know about carver/truma products isnt worth knowing

Thanks for the contact. We fitted a new element yesterday which ended up being quite involved and overnight the tank has drained itself again

If I ran it on gas for the week is it going to cost a small fortune? I don't know if it leaks on gas yet!

I don't think, relatively speaking, the water heaters use THAT much gas. I could be wrong, however, since I'm still fact-finding with mine.

But we have Gas-it fitted and, not knowing how much gas I'd used over a weekend away, I topped up with LPG at the local filling station and (very embarassingly) only managed to squeeze in 2litres (against a minimum 5litre uplift!).

I'm going to try again tomorrow since we've spent a weekend offgrid since, plus another with some heating and a week of the fridge being left on gas. So we'll see what the situation is tomorrow and I'll let you know. But I've so far been surprised at how little we use.

My Dad spoke to this chap today and he was brilliant so thanks again for the contact, he is highly recommended. He mentioned how troublesome the overflow elbows are (hot pipe) and that they are only really used for aiding draining the tank - this has now been swapped for a cold elbow without the overflow along with a cold water feed non return valve. Last night the tank drained but not onto the floor so the cold feed valve we suspect is the issue and letting water drain back into the aqua-roll overnight.

Not sure if we'll know we've fixed it before we use the van but the whole water system has had an overhaul now which, after 11 years, it probably needed anyway!

All the bits and pieces have arrived for our first time using a super-pitch too. Here's hoping the weather holds!

my pleasure mate, like i said gary is a top bloke

Well, back from holiday now and the hot water was faultless so thanks for all the help getting it sorted.

Midweek, I found out my parents have decided to trade the van in anyway but at least its all fixed for the new owners.
