Just finished the plumbing side of a new central heating system, we're now doing the electrics, I thought I'd run it by you first, to check for any potential errors.
I've drawn a diagram of what I propose to do:

I plan to have the system supplied by an MK 3amp circuit breaker, which will then be connected to a MK Fused Connection Unit with a 3amp fuse.
1. What size of cabling between the consumer unit and connection unit do you recommend, is there any benefets to using anything over 1.5mm2?
2. What size of cabling between the components of the system (thermostats), do you recommend, I was also thinking 1.5mm2 woukd be a good choice for this?
3. I was planning on using heat resistant flex between the boiler, pump and valves. Should I? And what sizes should this be? Is Butyl a good choice?
4. Is running the cables in the wall cavity, okay?
5. Lastly, I've read in my on-site guide that I should provide a 10mm2 earthing connection to any central heating systems, where should this be connected? 600mm from the boiler?
Thanks for any input, I consider by self a slight perfectonist, and I like to get things spot on. Thanks.
