ATF500DHW Hot Water kit to control Hot Tub

[daddypew]

Hi,
I have an Evohome system controlling all radiators and looking to add a heat exchanger to a hot tub.
The heatexchanger will be tapped from from the boiler radiator circuit via a motorised valve.

Can I use the Hot Water kit to do this ?
ie probe in the hot tub water circuit, valve switched as though it was the domestic hot water system.

What control would I have ? ie different temperatures at different times like a room setting ?

As I dont have one now, I cant play around with potential settings so any advise appreciated.

many thanks in advance

Hi Stuart,

This is sort of possible, but you wouldn't have temperature control like a heating zone would (as this is hidden in the installer settings).

I'm not really sure what you would gain as an advantage with this? Cool idea, but it was certainly not designed for this.

thanks for the reply,
Is it possible instead to treat the tub like an underfloor heating zone for instance and use a temperature probe in the water as the "room" temperature which would then give me full control ? (assuming I could set the room temperature aroung 40oC)
thanks

No, sadly you can't...

Is there another device that I could use to achieve this ? Something with a remote probe that I could set a target temperature via the controller ?
I'm happy to "modify" something to get the result, I've looked inside a T87RF2033 to see if i could access the temperature sensor to extend it, but all appear solid state.

Thanks again,

Stuart
