I recently had a plumber install an additional 2 radiators (both 700x400) into my gas central heating system. Forgive me, but I'm not altogether technically minded, but I know that he took the supply for the new radiators from the pipes which supply a radiator (400x300) in the downstairs loo. The new radiators (which are just through the wall from the downstairs loo) do work fine but A) they take an eternity to heat up as opposed to every other radiator in the house which heats up almost instantly, b) they never get as hot as the other radiators and c) if the thermostat on the radiator in the downstairs loo is turned up beyond (setting) 2 it seems to affect the output of the new radiators quite considerably.
I'm not sure if it's significant but it's a new-build house (2 years old) with plastic piping throughout. The plumber didn't use the same piping for the new radiators which is, I think, 10mm, instead he used 15mm copper pipes which are considerably larger in diameter than those which feed the rest of the heating system.
Another thing I remember from when I got quotes for the work was that one bloke said something about the supply for the new radiators would need to come from a 'main' pipe as opposed to a 10mm pipe which feeds an existing radiator.
I've had the plumber back to see to the problem but he doesn't accept that there is one - mainly because the radiators he installed do work, which they do, but just not as well as I think they should.
I'm not sure what other information is required but the boiler is a GlowWorm Micron 60FF and it's a fully pumped system.
Any advice on this issue will be greatfully received.
Many thanks.
