Hi We are about to get a new condesing boiler, and was looking for some advice on what make to get. Some plumbers have reccommended Poterton/Baxi, others have said to stay away from them and go for Worcester....... can anyone give me some good impartial advice on which is best (and why) ...

sorry for the dumb question - how do i know if it is an open vented system ? i do know that the boiler is not a combi :D

The ground floors are made of concrete. The rads are supplied by a pipe which comes out of the wall horizontally and then goes 90 degrees upwards to the valves.

thanks for that...... our pipes go horizontally into the wall, so I presume that they then go down under the floorboards ? what about downstairs (we have concrete floors) - would you suggest to leave the pipes as microbore here, as I guess the only way to cut them is to dig a hole in the...

Hi Be warned - very dumb question coming up !! I am about to put TRV's on my microbore system, but looking at some posts here I am confused. What are "Double entry" valves and what are "seperate inlet -outlet" valves ? Our rads have one feed on either side of the rad, so I guess...

so, if the "drain tap" (whatever it is on the rads) is below the TRV's I should be Ok to drain through here and then fit the trv's ? I dont mind if the carpets get a bit mucky as we will be replacing them all anyway. there is no valve near the boiler and i cant find anything similar anywhere...

Hi I am looking to drain my microbore heating system as I want to put TRV's on the rads (there are none on at all and some of the current valves are broken anyway). On my old system at my previous house there was a small "tap" downstairs that I connected a hose to to drain the system, but I...

Excuse my ignorance here, but I will be going through the same process in the summer . Can you please explain/confirm the following : 1) Isn't it a requirement now that you have to fit a condensing boiler ? 2) What does "bringing the system up to Part L" mean ? Does this automatically...

the toilet etc was in the house from the start, and are actually on the "higher" oart of the slope. Directly below teh ensuite is the hallway, as it was all built in one go. The floors do not bounce at all - it all seems quite solid except for the fact that it slopes.....

Hi, I hope someone can give some advice. We recently moved into a house (it was built in 1986) and have noticed that the floor in one of the bedrooms and in our ensuite have a noticeable slope on them (both rooms are at the front of the house, and the floors slope towards the back). There is...

Hi, I hope someone can help.... Every night we get a loud bang somewhere in the heating pipes. This happens about every 5-6 minutes, and sounds like someone has hit a pipe with a hammer. It continues for about 5-6 hours after the boiler/heating has switched off, so i cant imagine it is a pipe...

what is DS40 ? And would a powerflush really melt a microbore system ?

When you say the the clanking we get is most lilkely caused by the boiler, how do I find this out ? What happens is that as soon as the boiler comes on, there is a loud clanking that sounds the same as when the pipes expand and catch on something such as a joist, except that this happens the...

Hi We will be fitting a new boiler in a couple of months (the current one is really old and clanky) and I wondered if that would be an oportune time to replace the current microbore system with "normal" heating (as you can see, I am not a plumber so I hope you understand what I mean by "normal"...

thanks for the advice - will give it a go this weekend !

Thanks for that - I thought that was the case but wasnt sure. BTW, what make TRV's have you got ? Are they any good/reliable ?

Hi I am looking to fit TRV's on our microbore system, but only want to fit them on about 70% of the radiators (the other rooms we dont use that often so can live with them being on or off). Is this OK to do, or do we need to fit the TRV's on all the rads to keep the system balanced (? - not...

Hi - we recently moved into a house in which there had been a leak from the hot water tank and so the floorboards on the landing got wet. The previous owner did not replace them, and so now they are very springy and creak and groan whenever you walk on them (and I also think they then are...

Hi, I hope someone can help... Firstly let me say that i have no idea when it comes to heating, so apologies if this is a dumb question ! We recently moved into a house that is fitted with microbore heating, an old Potterton Netaheat Electronic boiler, and a Grundfos Selectric pump. There...

We have just moved to a house with microbore heating and I have a couple of questions which I hope you can help with. 1) when the heating comes on (and goes off) there is a lot of loud clicking as the pipes expand/contract that goes on for a long time , much more than in our old house with...
