Hi, I'm looking for some advice on a central heating system fed by a multi-fuel stove. The attached file shows what I intend to do with the majority of the work already completed. I've read some conflicting or unclear info from the web so hope someone can help. I guess the questions I have are as follows:
1. Can plastic be used within the system so long as heat can dissipate before entering the plastic pipe work such as through the tank, rads and copper pipe?
2. Will the combination tank be suitable or will it be too small to handle the heat output of the boiler?
3. Does the expansion tank have to be steel or copper rather than plastic (same goes for the float)?
4. Can the lower 5 radiators be run in 15mm plastic?
5. Am I missing anything that should be installed in a system like this?
Any advice would be appreciated. I also need to get it certified by building regs or a HETAS engineer (UK) to keep the insurance company happy and of course be safe.
Many thanks in advance
