Can anyone shed any light please..........we noticed condensation in our loft, with hot water running out of the expansion pipe, our rads downstairs were cold.
My heating engineer neighbour drained the system and ran a flush (inhibinter???) through, we had a few hours the next day where all the rads were hot with no hot overflowing water in the attic, with the pump on number 2 setting, but since then we can only get heating upstairs OR downstairs with the pump on number 3 setting and the hot water is pumping into the expansion tank again, the number 2 setting on the pump doesnt maintain the heat in the rads after being heated up by number 3......sorry im not the greatest at explaining
I cant work it out, its driving me crazy & Im really cold...... can anyone help??????
PS happy new year
