isolate radiator by timer

[uksoftware]

Hi,

This might sound strange or lazy but it`s what I want to do.
In our house we have a radiator in the conservatory and I wish to isolate it from the system during certain hours of the day so as to not waste heat when we don`t use it for a few hours.

I have access to the pipes (15mm) under the floor inside the house, what I want to know is this:

Can I fit a 220v 2 way divertor valve to the flow (or both) pipe using 22mm to 15mm convertors and then apply power to the valve using a normal timer when I want the water to flow.

This would mean that the valve could be powered up for say 4 hours and then off again, then later on in the day, powered up for another 4 hours and then off all night.

I don`t see any reason why this wouldn`t work but if somebody does, please let me know before I do it.

Sure you can. Payback period could be long though!

Cheaper - mount trv horizontally, put 40watt light bulb under it , turned on by timer.

Or See BES.co.uk part number 15754 & 5 and associated valve for a Danfoss electrically operated rad valve. COuld use programmable stat to operate it but obviously main htg would need to be ON for this rad to be on.

Or see Antares for similar bits, much cheaper though not your standard make.

Or - probably the neatest cos there's no real plumbing or wiring - look hard into the Danfoss range. You'll see a device which sits on top of one of their TRV's, with a digital clock in it. During programmed hours it reduces the temperature by ( I think) 4 degrees C. Would probably be best option.

Excellent, I like the sound of the digital clock trv, I`ll look for that.
Thanks for your detailed reply.
