Hi All I am a newbie to this site and as often happens I suppose I arrive with a problem. I have a conservatory with under floor heating. It has three coils of 15mm plastic heating pipe in between the joists.The three flow and three returns are fed by a 22mm. flow and return copper pipe from the boiler .
As usual I made the mistake of buying the 15 mm TRV's and then planning the job. I need to fit a TRV in the 22 mm.flow or return prior to the manifold to control the heating. So I suppose I need a 22mm straight TRV. I have asked a couple of people and have been told they don' exist. I find this a bit hard to believe. but what do I know I am an electrician.
If I put a 15mm TRV in with a reducer on each side I am afraid it will over restrict the flow.
If any one out there has any ideas I would be delighted to hear from them. Help please
Regards Frank G
