Pipes from boiler to Manifold

[iMCaan]

Hi

 

We have a boiler in attached garage with a concrete block cavity wall joining the house. The GF cloakroom is just on the otherside and the staircase is infront of the GF cloakroom. Both GF and FF are beam and block.

 

What is the best location for the pipes from the boiler to the manifold?

1. Between insulation on GF

2. Ceiling between the beams

 

With both option, will have to create an opening in cavity wall for the pipes.

 

Secondly, the plumber has suggested running a Tracpipe gas pipe to kitchen island with or without a conduit (with preferred). Pipe length is about 15 meters from gas meter to kitchen island. I've been able to source an alternative brand Teslaflex from Screwfix. I've never heard of a flexi gas pipe. Are Tracpipe/Teslaflex good alternative to copper?

 

As always, your suggestions/comments are highly appreciated.

 

Thanks.

Pipe runs for water, run in a way that doesn't encourage air pockets, high points will need a bleed point added.

 

Going up, across and down, will need a bleed point at a high spot, that may not be accessible now or in the future. So not best.

 

Going down, along and up, the bleed will be at the ends and likely accessible now and in the future, so better.

 

For gas pipe do what he wants, he has full responsibility, you providing parts becomes your responsibility, should anything be wrong.

 

Your plumber should be telling you this.

Thank you @JohnMo

 

The garage will have 100mm reinforced concrete floor and then there's weight of the car. will it be better to run the pipe in conduit closer to wall or should running straight across the garage be OK?

 

Thanks

I would run around the wall, but it will need to be insulated, not in conduit. Use 25mm wall thickness insulation.
