Please can someone give an opinion on this. I am trying to fine tune my system and have been trying to eliminate the air that the pump pulls in from my open vented system. The RGI installed an aerjec de-aerator but it does gurgle a bit and hasn't eliminated the problem. The RGI I had do...

I have an open vented ch system which has always drawn some air in. I have had to vent my towel rails every 3-4 days. Yesterday an RGI fitted an aerjec de-aerator into the system and I wondered if these are any good. It certainly makes quite a lot of gurgling noise.

I have a Worcester Greenstar 40cdi - conventional open vented system, with an automatic bypass valve. My system layout was H shaped and pulled in quite a lot of air as I have a 15/60 pump. Today I have had an Aerjec de-aerator put in and the pipes 'tied'. Pump over run is wired in and goes on...

Have finally sorted out central heating system and all is working fine. I am left however with one or two minor irritations that I would like advice on. Since having a new boiler fitted (worcester greenstar 40cdi conventional) , my two towel rails make a noise like a toilet cistern...

I have noticed that since the Worcester Bosch engineer put in a new pcb and heat exchanger (into my brand new boiler) there no longer seems to be a pump overrun when the boiler switches off. At least I think it was after he had been. I also had a new pump fitted by an RGI four days later...

Tonight the house started to feel a little cold. Felt the radiators and they were cold - went to the boiler WB 40cdi conventional and the display was flashing a very odd symbol like half a square in the upper left corner and the same in the lower right corner - L shapes into the edges of the...

Have now found me a good RGI and everything seems to be working as it should :D I have read the thread about "Which Boiler", and considering I have now spent many many many thousands getting my CH going again I was a little perturbed to read that some of you think that modern boilers have a...

I have posted this under my previous heading of dirt and air in the system, BUT the problems I have now are much greater. Need advice as to whether this is a job for an RGI or whether to get an electrician in Following all the problems I had with being left with a dirty system following a...

Can the RGI's on this board give me a rough idea of how much you would expect to pay for power flushing of a system with 22 radiators. Thanks :D

Hi - wonder if someone can give me a bit of information. Following a visit from a W Bosch technician today the 'eco' button on my 40cdi conventional boiler (not combi) has been lit up. When I look this button up in the manual it just says 'not applicable'. It wasn't lit before the visit, it...

Thanks :oops: Well at least I have a good pressure and the boiler is ok. Just need a few other problems sorting out now - couple of radiators not heating and need bigger pump. Hopefully will soon all be sorted.

Following the extremely expensive installation of a new boiler before Christmas, I am left with a noisy system. I am not sure whether the noise is coming from the new boiler, the pump or from the black solenoid thing attached to the Dayton wireless thermostat. It is a loud vibrating hum that...

Hi - I am probably being a bit neurotic following the problems I had before Christmas, with the installation of a Worcester Bosch 40 cdi condensing boiler. I notice that I have very heavy and continuous pluming coming from the flue on my garage roof and wonder if this is correct. I know this...

Hi - I have been told today, by a different gas engineer that I have a 15-50 central heating pump and that as I have 22 radiators it is insufficient and it should be upgraded to a 15-60. My question is would a 15-60 pump be sufficient or would I need to go for something even larger...

Hi again. Following the installation of my new boiler, a power flush and the fitting of a Magnaclean system, I am finding that some of my radiators are ice cold at the bottom and hot at the top. In my living room I only have one radiator working properly. I thought this problem was...

Hi - please please I need some advice. Four weeks ago I had a service on my boiler done under my Homecare agreement with British Gas and they disconnected my boiler because it was spilling. Two weeks later (BG not having done anything - supplied estimate for new boiler etc) I contracted a...
