i have a system that was installed over 2 years ago duel heat source (gas boiler and wood stove)
every time we put the heating on the overflow starts running this doesn't happen when its hot water only. we have 16 radiators mixture of doubles and singles and only 1 pump on the system that is set at its highest setting if its turned down some of the rads will not heat
question is
should i install a second pump on the ground floor return to take some of the presure off and will this resolve the issue
thanks
