Hi all.
A friend's back boiler has packed up and he wants to replace it with a combi boiler. I will do all the pipe work for him and a corgi engineer will install the boiler and connect up the gas pipe to it. He wants to position the boiler in the kitchen, upon recommendation of the gas man, where i will have to dig a channel in the solid floor to allow the pipes ( flow, return, cw, hw and the gas bloke will run the gas one) to reach to the boiler. My questions are:
1) How wide has the channel got to be to accommodate the five pipes ie; distance between pipes.
2) how deep has the channel got to be to accommodate the insulation around the pipes and the sleeve.
3) how thick has the insulation got to be and what sort of insulation do i have to use
4) diameter of sleeve and what material
5)what to use to seal their ends
6) do you know a quicker option but not a cowboy one.
Thank you for your time.
