Boiler changed to combi.
Old system had a branch from the outflow through a coil in the tank.
Plumber just linked this to the inflow when he removed the tank.
To me this seems like a short curcuit, a low resistance short way for much of the hot water to go straight back to the boiler.
I said to the plumber wouldnt it be better just to block these (forcing all the water to go round the rads)
He said 'no then ur only return is through the rads, I like to keep things moving a bit!'???
Does his theory make sense?
The rads are still getting warm but I cant believe that in parrallel short curcuit is helping??

The only reason I can think of for doing this is that your pump is too strong/large. The plumber must think that the pump may be hurt by too much back pressure. Or he didn't want to change the pump. The only drawback to doing it this way is the pump will be running a little longer. A little more electricity is used. Otherwise no worries.

What you say don't make sense?
Your boiler makes hot water from a coil located in the boiler hot water. Cold water goes in and hot water comes out. A very inefficient system and the boiler has to be on in the summer to make hot water. Correct this problem: Cap off the inlet and outlet to the coil and install a hot water tank.
