Advice on a new system

[F49h]

Hi Guys and Galls :confused5::confused5:

I am installing a new central heating system with a external oil boiler. I intend to do all the pipe work and let the professionals fit the boiler. My plan is as follows:

22mm Copper pipe to and from the boiler in to the loft up through the chimney Approx 10' run. Copper pipe for water supply
Plastic 22 mm pipe ring main with inserts and compression fittings with copper olives. 22mm - 10mm T's (compression)
Plastic 10mm drops to the radiators buried into the wall. No fittings in the wall. Pipes will be clipped secured.
( do i need to insulate the pipes in the wall and any recommendations)
Auto air release valve at highest point of the system (in loft)

Is it better with inserts and compression fittings (access not a issue) or push fit fittings
Best plastic pipe for the job or are they all the same.
Does any one see any issues with this.

Cheers guys

Those all sweeping statements, I have been in the job for the last 45 years and I have got a clue what you are doing, need a bit more data than
that, maybe some bright young things on here will spot what you are intending doing.

I am happy you went that far. After the first line, I lost interest. Not a good thing to do, but, I just did. Sorry

Hi guys
My Iflo power shower has lost its power. I removed the cover and noticed that the internal pump was very slow to turn. I suspect it is the brushes. problem is where do you get spares or is there an alternative.

Cheers

In my opinion and im not young either, if your using plastic then comp and inserts yes. what do mean by ring main. Dont make a ring of flow and return in 22mm cos it will just short circuit.. can you give us a drawing or something to get our teeth into.:smile:

Here we go, watch this space I have much to learn Obi One Kenobi :banghead:

and watch that rot out in 2 years or less!!!!!!!!!!!

[/QUOTE]Copper pipe for water supply[/QUOTE] seems ok

[/QUOTE]Plastic 22 mm pipe ring main with inserts and compression fittings with copper olives. 22mm - 10mm T's (compression)

( do i need to insulate the pipes in the wall and any recommendations) why, warms the house and cracks the plaster, personally I prefer drops behind curtains, hidden but warm the room as well.

[/QUOTE]Auto air release valve at highest point of the system (in loft)[/QUOTE] as normal

How do you insert a drawing.

What I mean is run a flow and return pipe from the boiler and T off each radiator from the flow and then T each radiator to the return.

Each to there own opinion but im first fixing new builds at the mo and im having to do it in plastic, (not my choice) and i firmly believe that not only i could do it in copper just as quick but copper work out cheaper, but thats just my opinion plastic carp,

Is it a combi, heat only or system? I.e. is it a sealed system.

Why run pipework in a chimney.

Have you actually had somebody who knows what they are doing look at this?

 

[F49h]

It will be a combi and a sealed system. The boiler will be outside. The Chimney is the easiest way to get the pipes into the loft space. had some to look at it but doubtful they knew what they knew what they were doing. quoted 7 K!!!

I wouldn't run the pipes in the chimney, let alone anything else you wont be able to clip them for support. Plastic is much of a muchness, get a recommendation from the merchant you plan to use. consider lagging pipes in wall with hair felt lagging. Good luck

Yep they knew what they were doing £7000.00 tidy boys, was the bit in red and echo up the chimney, I suppose there are ways of using the old chimney as a route up, you need to make absolutely sure that any pipe does come on contact will the side walls and therefore some heavy duty insulation, I don't know how your are going to get the pipe up there, plastic looks like
your only option, no joints in it please, you will need to turn 90 degrees at the top that means a joint in the chimney not good, find another route up inside and box it in far safer.
