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).
Report back to CUK with any disasters / findings (including family evacuation)
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).
Report back to CUK with any disasters / findings (including serious injury)
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.
Report back to CUK with any disasters / findings (including serious injury)
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.
Report back to CUK with any disasters / findings (including, floods, family evacuation and serious injury)
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

Flushed with success surely not this is suity.

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.

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!

And spoil our fun! Are you mad??

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

[SimonMac]

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

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.

Justifiably so in your case.

Just a tip OG - Your sig is out of date, because no one is suggesting a second referendum. We've moved on now

[Old Greg]

Why make the post then

Suggest you get the Pros in, ASAP, sounds like the whole systems seriously chunted and could blow at any time

Thanks Dallas dad. I disagree about the black sludge. It is iron oxide, which is attracted to magnets.

Red rust (Ferric Oxide, Fe2O3) is not magnetic, but black rust (Ferrous Oxide, FeO) is.

Since we moved into Benger towers in 09, we've always had problems with our heating. Elderly Gloworm boiler, and intermittent faults with the radiators. Several plumbers have mentioned the system is on it's last legs, and is heavily sludged. One plumber said that my radiators were only working at 25% efficiency. How do they measure this?

So I got a quote for power flushing. £450. So I looked into hiring a power flushing unit for the weekend. £160 + VAT + chemicals.

So I shopped around on ebay and got a second hand one for £141 (winning bid) which came with 2 bottles of Fernox, a bottle of Powerflush cleaner, a bottle of leak fixing stuff (around £80 worth).

And I've been at it for 3 solid days now. I'm on the penultimate rad.

I'm going to fit one of these



So there you have it, sometimes bleeding the radiators isn't enough. Once this is done I expect the contract market to pick up.
