Okay to fit a radiator this way ?

[WhatNext]

Morning

I was wondering if someone could please advise.

I have an S Plan sealed CH system. The system boiler is in the garage. The 2 port motorised valves are up on the top floor - one for CH and the other for the HW.

I plan to insulate and convert the garage in a general purpose room and was thinking about having another radiator ( with a TRV ) installed by connecting it directly to the flow and return at the boiler.

I understand that this radiator would only be heated when there was a call by the thermostat in the hall ( which would open the CH 2 port valve and power up the boiler and pump ) and that the lockshield valve would have to be screwed almost closed other wise the radiator would be acting as a fixed by pass and steal all the heat plus the flow.

Are there any downsides to doing this apart from the lack of control ?

Thanks

It will also heat when the hot water is on. Unless you turn the trv off.


But other than that, it should be cool.

Dan, it will only be cool when the TRV is turned off.

Dan, it will only be cool when the TRV is turned off.

No HD, Dan uses that term as OK. It's one of his English middle class sayings, that was commonly used in his 'Red Brick' Uni, when he got his degree & Phd in Applied Neddlepoint & Sewing.

Thanks ! I forgot about the HW - a great point !

In the future I am thinking about installing the Honeywell EvoHome system. From what I have read and understand the radiator controllers HR92 would allow me to zone this area and give me control - am I correct ?

Can't you tee off from hall radiator or kitchen, through the wall to garage radiator?

yes but you will have to fit another 2 port zone valve to the pipework going to the radiator in the garage

you will have to fit another 2 port zone valve

Not with Evo.
