Building regs and heating zoning

If your radiator is pinging alot the most common cause us the radiator is hung on an uneven wall. This puts brackets and radiator on a strain in cold state then when heated up the cracking occurs. It also may have something missing on bracket. If radator is on same floor as bedroom it is correct to be on that zone. I would get your heat calculations redone for that area if you need it on alot to heat hall. Regards Chris

Radiator noise is probably it has not been fitted correctly both vertical and horizontal also check that the plastic fittings are in the bracket Surely plans for the design of the system should have been viewed from plans If difference then back to the builder

1,Building regulation for zoning areas are only there to reduce greenhouse gases and preserve energy, therefore as area that are not in use at the time like night and day should be plumed in different zone, so having ground floor radiator connected to bedroom doesn’t make sense as bedroom zone is separate then down stairs and you don’t need to heat upstairs other then when you are using it and that’s at night that keeps your downstairs hall way cold during daytime when you actually need it as that zone of the house you are using during a day time and not at nighttime and 2,one can argue that it will fail as original idea of having separate zone so you can save energy’s well make less greenhouse gases and having to heat upstairs as well as downstairs when you don’t need it beats the obvious reason zone were created. 3, the reason it makes noise in most cases is when copper pipe are clipped too tight under floor without using hemp around clips for allowing pipes to move when expand and extracts during heating and cooling, sometimes pipes are run in a way that they are touching buildings surfaces like joist or walls and not allowing pipes to expand or extract.That would need further investigation to see what causes it. 4- under size pipework dose restricts flow of water in many cases, in this from what my experience tells me is that it has been branched from bedroom radiator and not from main 22mm ring circuit as it should be done , best solution for this would be that as it’s connected to wrong zone any way it would be wise to disconnect from bedroom radiator pipe and repiped to downstairs zone by making sure it’s connected to main 22mm ring circuit and not nearest radiator pipe that was available otherwise it will have same effect as before as water flow get reduced and one or both radiators don’t work as efficient as they should do,

I'm sure you asked this similar question a week or 2 ago. Basically if you are looking to find faults with your plumber or builder to either correct the works or sue them, you will need to employ a plumber to do a full written report and pay them for the time it takes. That way you will have something in writing to go back to the installer or builder.
