My radiators

[Wilmslow]

Anyone tried fitting thermostatic on-off valves to individual radiators? Are they any good?

I gather some (the cheaper ones, or maybe the opposite, the fancy electronic ones?) can hum constantly, which is not what one needs when trying to sleep.

They are fitted in place of the radiator tap, and I think most work by a thermally expanding ring of rubber or something similar that effectively turns off tha radiator, or slows the water flow, when the room temperature goes above a certain value.

I was in a Best Western at my last gig with electronic radiator valves connected by wifi. Hummed and clicked like anything. Terrible invention. Tried to remove the darned thing which locked it into full open boil the room mode.

Calling someone that knows what they are doing

Wash your mouth out sir. It's not the suity way

Its not Suity's clients way either

Actually, Suity, scratch that, as you are on the bench consider it a useful time to brush up on your plumbing skills

Ah yes, thanks. I had a feeling the flash electronic ones would be more likely to do that.

So old fashioned analog(ue) wax ones it is then!

Flushed with success surely not this is suity.

As per NLUK.
1. Drain the system (you should be able to find a drain point at the lowest point in the system, failing that do it from the lowest rad).

2. Remove each rad in turn and pressure wash out (I notice Europarts have one for £40, less with the current 15% on line discount).

3. Replace one valve on each with a mechanical TRV (£5.24 in quanity with the corresponding exit valves and compression joints . These are silent in operation. To fit ensure you have 2 good quality adjustable spanners.

4. Refill the system, starting with only 5 liters or so and check each new valve is not leaking. If using an inhibitor add it to the system when it is not yet full but is also not leaking from any of the valves.

Just done all of ours after replacing the back boiler with a modern condenser. You get the chance to pick some nice decorative ones for the lounge on the money you save. Cheap decorative rads
