To Powerflush or start again?

TF · 11 Nov 2006

Hi,

Some up to date advice required please.....

Here's the low down: 5 bedroom house with approx 18 radiators. Potterton boiler at one end of house (in garage). Some radiators have a temperature control.

BG service the boiler every year and last time suggested we should have our radiators powerflushed. I think this costs approx £500???

One or two radiators stay hot all year round (even with thermostat set very low) - BG say this is normal, some sort of release area for the hot water???

The opposite end of the house (lounge & bedroom) to the boiler feels very cold compared to the rest of the house. BG say it's normal because the hot water has further to travel and also the powerflushing will help this???

Ideally we'd like to be able to control the temp in each room and also control when the heat goes on and off in each room (rather than the whole system). Is this possible??? What's the latest and greatest CH system?

Any help very much appreciated, as I know very little about all this...

Regards
TF

If B.G will do 18 rads and guarantee results for £500 .....I`d snap that up

For once someone will get value from them

BG often recommend Powerflushing, and used in the right situations, it is most effective.

However, none of us here have had the luxury afforded to BG in that we haven't seen your property or had a shifty around your rads. Heating people (such as BG's staff) often recommend a PF when they are not sure why a circulation problem is there. So my advice would be to get an informed second opinion from someone who has seen your system

As far as the zoning you would like, have you thought about Honeywell's CM zone system? See www.cm-zone.com

Ah, BG haven't said they'd do the powerflush for £500, they just recommended that we got it done (by someone else) and suggested that might be the price.

I'm in complete agreement about being ripped off by them, but that's another story......

Thanks for the link to the honeywell site, I'm off to take a look now.

Thats a first.

My mate in the know tells me that they charge approx £550 and guarantee it for ever or as long as you pay them your monthly fee.

I'd be suprised if BG will powerflush 18 rads for £500. they charge this for approx 8 rads so may be near £800 at a guess.

You mean the room/s feel cold .......or the rads themselves

................I do Surrey occasionally to help a M8 who`s there ...............Guildford area we could have a look -Gratis - and possibly advise

Thanks for the responses.

At the weekend, I fiddled with the temperature control thing on the rad in the lounge . It was set to max, so I turned it down, then up again a few times and hey presto, HEAT!!!

Looks like the thing had got seized up.

If you can remove the thermostatic heads on those rads with them then tap the pins firmly, but not too hard a few time with a small specialist tool (hammer). Make sure they move freely. You will then be a fully paid up member of that great Northern institution the "Pin Tappers and Shunters Social Club".

Oh..and your rads may work a lot better as you have found!

Sorry if this sounds like a silly question, but if I remove the temp control heads, will the water will fly out?
(I'm thinking this is what restricts the water, so if I remove it, the water will escape)

no but if you remove the pin it will (voice of experience )

make sure all the pins come up as suggested try tapping them as they do stick now and then

JohnD · 17 Nov 2006

No it won't. The thermostatic part is not part of the water valve.

The valve is operated by the pin that sticks out of the top of it. The thermostatic part presses down on this pin.
