I Have a Glow worm 30CXI combi boiler fitted in my loft space. All the radiators heat up ok apart from the last 2 on the run and they very bottom of the house one in the cellar and one on ground floor. I can get them to heat up ok if I turn 2 other rads off on the ground floor, I have balanced the rads as well.
Do I need another pump fitted on the ground floor due to the fact the boiler is fitted in the loft and the drop is to far to circulate the water?
If so can you recommend the best pump and location.
Many thanks
