hi Everyone, i have had a new single panel radiator installed in my conservatory but have an issue am struggle to understand.
the rad is 500 x 1800mm. all the pipes in my property are the borehole plastic pipes and same was used to extend the heating to the conservatory. the heating was taken off the pipes feeding one of the radiators in the lounge. this radiator in lounge is the nearest to conservatory.
now the problem is that the new radiator gets hot at the top half but the bottom half only ever warms up.
i switched the rad in lounge off to force all the water to new rad in conservatory, but i found out the new rad heats up quicker but still only top half (it does get very hot though but only top half)
i know its not sludge at the bottom, as its a brand new radiator. also not one of the old rads already in the house has this problem. the TRV and lockshield valves have been checked and both ok with reasonable flow.
could this be due to the radiator being too big for the borehole plastic pipes?
also as the new piping was taken off the nearest radiator in lounge- there are about 4 elbows before it could get it to the conservatory.
could the 4 elbows/bends be responsible for the fact that the rad only gets hot at the top part?
Also the flow is from the lockshield side and return is TRV side- could this be the issue?
what does the 'K' sign on the lockshied valve mean please?
please see pics attached
