Hi, I want to use push fit connectors on 10mm central heating pipes. The type I want to use say suitable for central heating but are they suitable for sealed systems? Help appreciated

How should I do that? Close all bleed valves and refill to 1.5 bar and look for leaks or will I need to bleed as well

Hi, I have read a couple of posts ref refilling a sealed system but cannot find one that explains it in great detail. I have moved 2 rads and installed another in a new front room. I now need to refill. I will be putting some Fernox in first. Can anyone give me a step by step of what to...

Thanks again. Will get on with it!

I thought as much. Thanks for advice.

Thanks all for the advice. I will look at using 15mm flow and return and reduce to 10mm at radiator. Cheers

Hi, I am adding a radiator to a new front room. My heating system is 10mm micro bore on a sealed system. I have read something about using correct pipe for distance the rad is from the feed pipe. The new radiator is on the ground floor and the pipe will have to run under the concrete...

My system is micro bore and all in 10mm. Should I use 15mm pipe from 20mm feed up to new radiator and then reduce to 10mm??

Hi, Can anyone tell me if you can get a straight solvent weld connector for 22mm plastic pipe? The pipe is the incomming water feed for the house (blue) or do I have to make do with a compression or push fit? cheers

Thanks for your reply andygasman. I take it you mean run the 10mm plastic covered pipe through the 15mm pipe. Is that what you mean.

I am going to add a radiator to the downstairs but the floors are solid and I will have to run plastic coated pipe under the floor. Can someone tell me how deep I need to go with 10mm pipe and how far apart does the feed and return pipes have to be from each other under the floor?

Hi, I am going to put a mat well in my front porch. Can anyone direct me to a site that sells the surround. I have looked on line and I can only find mat well frames. I have seen mat wells in magazines etc which have a 4-5 mm metal border around the mat. This is what i am looking for...

Thanks, Will get plimber out in morning. Have I damaged the boiler? Only ran the water for about 5 mins. What an idiot!

HELP! I needed to take a radiator off the wall and because I was going to move it anyway I thought I would drain the central heating system down as it is summer anyway. Problem is that now I have no hot water and having tried to get the water running I may have damaged something in the...

Thanks : SE calcs and drawing stipulate padstones at 300 x 100 x 215 so SE happy! Cheers for your help, I will leave piers at 100mm and tidy them up to match the width of the beam once boarded up..probably just dot and dab plaster board onto brick work and skim. many thanks....

Many thanks. The beam will sit below the ceiling line, so looks like I will have to increase the width of the piers. I want to use the original wall for the piers and not rebuild them to 153mm. I think I will leave 300mm of the original wall both sides and have to clad the pier to match...

Hi, Can anyone help? I have the calculations from my SE and I need a beam 3.45m in length and 152x152x30kg/m UKC. Am I right in saying that the beam will be 15.2 CM in width? If so will this be OK to sit on padstones and brickwork that is only 100mm thick? Or am i being thick? help...

Cheers for the advice. With regard to depth - can I go down maybe 1 inch or so and then screed over the top or do I need to go deeper?

Hi, Can someone give me some guidance? I am going to add a radiator to my micro bore, sealed central heating system. It is on the ground floor which is solid concrete. The current rads downstairs a fed by pipes that have been channeled into :? the concrete floor. I am going to have to do...

I have recently bought a 25 year old house which needs the heating system upgraded or maybe renewed and I am going to be knocking through my dinning room and kitchen. Instead of upgrading the radiators in these two rooms I am looking at using underfloor heating. The rooms have solid floors...
