Truma Ultrastore Water Levels

Chatting to our mobile caravan engineer the other day, he advised us not to leave our water heater on overnight.

His view was that as the pump wasn't being used during the night, the water level would drop below the level of the heating element and cause a burnout.

This event would not then be covered by any warranty.

I would assume that for efficiency the heating element is in the bottom of the tank [hot water rises] and in a good system nothing would drain back unless air was getting in somewhere, somehow. My first thought is the caravan "engineer" is no such animal, just a part competent amateur trying to make some money.

Mack100,

I agree with Screenman & geriatric. there should be a thermal cut out that will prevent overheating and maintain water at 70c. Plus, the element is located in the bottom of heater as in a kettle, only way it would drain is if there is a hole in tank below element or drain valve left open. Maybe he is a caravan "environmentalist" ;) rather than an engineer, trying to save on electric.

As has been said, unless you have a leak in the water system or the non return valve is not working, then what you have been told is rubbish.

 

as long as your water system is in good order it is quite safe to leave the heater on all night

Not so, he is a highly competent and skilled caravan engineer who has every certificate going.

However, I take on board all that is said here and assume that perhaps truma water heaters are a gap in his knowledge!

The Truma water heater has an overheat trip switch built in to it, so even if you switch it on with no water in it, it will just trip out and not burn itself out. We leave ours on all the time.

That may very well be the case, and if you are happy to use his services good for you, but on the evidence of his comments re the hot water system I would not let him anywhere near my caravan.

Nor me. Have caravanned for years and left the water heater on. Never had a problem. Think he may be a little mistaken or perhaps misunderstood!!!!!!! :wub:

The only criticism of my hot water system is that until I added a mains neon there was no indication the electric water heater was switched on. Twice I came home after EHU use and left the heater on for 2/3 weeks without using any water. Never tripped out, never burnt out, just cost me pennies to keep a tankful of water hot unnecessarily. I blamed the Boss, iit's her job to do inside, I do outside. She said she couldn't see the little red bit on the switch - that's why I added the neon.

Thanks for the advice, I didn't realize he was so useless.

 

Hi Mack,

If you were happy with his abilities previous to this issue, why not question him on the subject as he may explain what he meant,

As said before, it's perfectly safe to leave the water heater on overnight.

 

It's fitted with overheat protection. If it trips, switch off for 5 minutes and switch on again.

 

You'll damage the overheat device if the water heater is left switched on for prolonged periods with no water in it, but these can be replaced without having to change the complete water heater.

Good bit of kit until it goes wrong- then it's fundamental weakness comes to light, ie, it's a sod to work on!! :lol:

 

However, overheat protection is not a weakness, it would have to be well covered on this score simply to gain CE approval, worst case would be the overheat to trip and as can happen. .. refuse to switch back on again!

 

I'm trying to think of a plausible possibility to suggest otherwise? is it possible for the water to syphon back into the aquaroll perhaps?

Or infact that it has ever been fitted !!!

Also I have known it to be fitted on the wrong side of the drain valve :blink:

LOL, seen that before to

 

The NRV in the pump housing would have to fail too

or as happened to me the NRV failed back to the onboard tank, left with an empty heater and sizzling noises when the tap was turned on to wash in the morning after turning on the heater 20 minutes earlier. IT DOES HAPPEN. geo

Have I misunderstood this or do you really mean that you tow your caravan home with the water heater tank full of water ?

 

Or perhaps you meant you left your caravan on site with the EHU connected and the heater left switched on ?

Hi Barney,

I believe many people, some of them members on this Forum, do tow with the various systems, such as water/toilets etc, charged. I think it's a lot of uneccessary weight to be towing around but each to their own :D,
