Truma Frost Control Element (1 Viewer)

[George Thomas]

This is the small heater element which plugs into the frost control valve at one end & plugs into my Combi 6E at the other for it's power.
Does anyone know where I can buy one. I believe the Truma part number is: 70070-01.
Thanks George

Out of stock if you try and order. Been trying to get on myself. I messaged them and they do not know when in stock.

Thanks Kups & Guyadria - I did find this on outdoor bits but out of stock. Also leisureshopdirect are awaiting stock. Will keep looking. Cheers.

Hello all - have just received the Truma frost control heating element unfortunately no fitting instructions. Not really a problem as it’s obvious where the plug ins go but I can’t figure out where the supplied bracket is supposed to fit. Any ideas please. Thanks George.

 

[Guyadria]

Any chance on letting on where you sourced it from? I still want one. I believe the Truma boiler has a specific connection point for the plug under the connection cover, and obviously the heater element slots into the frost control valve. I imagine the bracket is to keep it in an engaged. Guy

Had one delivered the other day. Cant find the email where it came from, they are out there.

 

[George Thomas]

Hello Guy - I’m sure will figure out the bracket. I purchased this from Leisureshopdirect (they were showing awaiting stock but also said when they were expecting stock in & have found them reliable so I ordered) only waited a week. All the best George

Just a point they only work while the heater is on so unless your frost valve is in a cold spot nowhere near the boiler there is not much point in fitting one.

Hi Lenny thanks for your thought - we realise the heater will need power for this to work & our valve is away from the heater & in quite a cold locker. Our intended use is for when we are staying in the van & not wanting the heater to drain down. We would keep the heating on at a low setting say 10 (don’t want it too hot in bed) to stop other water bits from freezing. I think it’s important to plan how to use this addition as in effect you are disabling the heater frost protection - hopefully we have it right. All the best George.

Hi, I have a heating element but have yet to fit it. Any instructions or guidance would be great. Andy

See this image......the existing screw to the floor holds the metal bracket down , this bracket keeps the plug in element in place.

Fab, thank you.

 

[George Thomas]

Hi Vanderek brilliant - I haven’t tried to insert the element yet but I now see the way I thought it would go was all wrong - seeing your image explains how the bracket fits. Many thanks & stay safe. George

I have been in contact with the firm that Vanderek mentioned and can get one of these through them. Before I send for one, do they work? Last couple of nights we have lost all our fresh water through dumping by the frost protection valve. Have a few ideas that may help but considering this element as well. Thanks

 

[Vanderek]

Madmag What no one has replied... yes I can can confirm mine does work

 

[Madmag]

Thanks for your reply. We have sourced one but not ordered yet as have found that reason for frequency of water dump is that the air vent pipe which is meant to carry warm air past the valve has become disconnected so no warmth getting near at all. This is being fixed tomorrow so ordering of heater put on hold. Couple of questions please, does it just increase the temp at which water is dumped or is it just so you can fill sooner. Also presume the power to run it comes from battery. What needs to stay on in order for it to work. Thanks again

It plugs into the PCB on the Combi I'm fairly certain the heater has to be running either for heat or hot water for it to heat the valve.

 

[Vanderek]

It needs to have the control turned on..ie just the display...the heating or water heating does not need to be on....it runs on 12 volt at 0.4 amp and supplies the element with enough to warm it up to 10°c ...prevents the valve from dumping.

That sounds a bit dodgy as the display is always on as they are normally wired to a permanent supply so it will stop the boiler dumping when the van is freezing. Not much point in fitting one if that's the case.

Hi Vanderek & Lenny HB . Sorry for being a bit thick but still confused as to when it is turned on or off. Do you have to turn the Truma system off completely in order for it to be inactive. I am thinking in terms of what to do when our van is parked up at home. We keep it on EHU but don't use the Truma heater only a small oil filled radiator to air the van. We don't usually drain the water down as use it in the winter and accept that if it has been very cold then the water will have been dumped by the valve. If one of these heater elements was to be fitted I presume I would have to make sure the Truma was switched off completely while we are not using the van so the frost valve can do its bit. I see its main use as being when we are away in the van and temperatures drop. We would keep some heating on but the heater element would be a back up to stop the water being dumped. Would doing this be a safe option. Thanks

 

[Vanderek]

As far as I understand, when you turn on the Truma control panel it supplies 12v to the circuit, this would keep the element active, ( the heater and water can be off.)

The following from Truma shows the element operates to 7 deg. The text indicates once the temp drops below 3 deg it dumps, unless you have the frost control fitted and active

So you could park at a supermarket and if the temperature drops to less than three deg you could loose your water, but if the frost control element is fitted and the Truma control panel is simply turned on ,and your 12 v electrics on too, then you have the element active.

From the manual......
At temperatures of less than
approx. 3 °C the FrostControl
opens automatically / without heater op-
eration the FrostControl can-
not be closed again until the
temperature reaches approx.
7 °C / use heating element for
FrostControl

 

[Madmag]

Thank you so much for that. Appreciate your help. I think that’s sort of how I was thinking. Looks like one for us.

OK

As far as I understand, when you turn on the Truma control panel it supplies 12v to the circuit, this would keep the element active, ( the heater and water can be off.)

But the CP-Plus controller is perminantly on so if you had a cold snap it wouldn't dump.

 

[Madmag]

What is the CP-Plus controller please. Surely there should be a way of turning the heater off. Don’t want to get something if it may cause damage but equally would rather the water not disappear overnight! Luckily we always fill the kettle before bed

 

[Lenny HB]

What is the CP-Plus controller please.

[Madmag]

OK. So can this not be switched off?

 

[Lenny HB]

Not if its wired correctly Truma say it should be wired to a perminantly live supply.

 

[Madmag]

Thanks. I think I am probably overthinking all this. Grateful for your input.
