Poor central heating throughout the house

[RakC]

Hello, I am after some help and advice. My Mothers home suffers from poor central heating, regardless how long the heating is on the house never really gets nice and warm. To give some background on the systems: boiler is a glow worm flexicom 18hx which was fitted in Nov 2007 following previous boiler failed (property is 15yrs old). The house was originally a 3 bed detached however the integral garage (where boiler was housed) has been converted to a bedroom with wet room which involved the installation of two more radiators. The house has 5 radiators on the ground level and 5 radiators on the first floor. Over the years through BG Homecare parts have been replaced such as pumps, valves and boilers parts. I was wondering if someone could give me some possible options to why the heating does not work as efficiently as it should. A couple of radiators may heat up well but generally they are luke warm and do not provide enough heating. I am wondering if (a) the boiler needs to be replaced for a more powerful BTU unit, (b) if it is possible that a more powerful pump is required to circulate the water better, (c) a power flush may be required, (d) any other suggestions??? Thanks if advance for any responses/help.

it could be a number of things. bad circulation because of many factors, sludge, poorly installed boiler, etc......etc......

did the heating ever work well with the old boiler?

Hi, to be honest even with the original unit the heating was never that good from what I can remember, it has always been a fairly poor heating system unfortunately

Might need a re pipe. Where are you based?

Probably down to poor design of the original system. I'd get someone in (other than BG homecare) to do a full survey of the system and recommend how to get it working properly.

plumber0808 the property is in Milton Keynes, Buckinghamshire.....Mike that sounds like a possibility that it was a poor design from the start, could you give me any indication on how much a full survey could cost at all?? Cheers

well if you get the boiler serviced you may get some good advise for free?

post in the "im looking for a plumber section" or whatever its called and you may find somebody on here will be able to meet your needs.

Free

nobody changes for that advise. With possibility of getting the job to put it right.

yes if your being asked to quote for work, but if your being asked for a survey of the condition of a system then without knowing what work may come of it then your gunna possibly want to cover your time.

it depends what depth your going into tbh.

The boiler was serviced last month by BG but as I don't live there I didn't have the opportunity to ask any questions......the suggestion of a repipe could be worth looking into, I have always thought that the pipes going into the rads are rather thin....look about 10mm...I think will be worth ringing a few plumbers/engineers and asking about a full in-depth survey being carried out.....thanks

Get rid of BG what u save will pay for a new system in 5 years?!

as a start you could check the approx rad sizes yourself by using a online calculator. this will give you an idea if the rad are sized correctly for each room.
