Dimensions and screw connection size
The only things you need to take into account when purchasing an appropriate pump for a central heating boiler or underfloor heating system are the dimensions and the screw connection size. Dimensions refer to the length of the pump, usually 130 mm or 180 mm, and the screw connection size refers to the diameter of the pipe through which the water runs. Compare them with those of your current pump to determine what size you need to select.The only things you need to take into account when purchasing an appropriate pump for a central heating boiler or underfloor heating system are the dimensions and the screw connection size.
