    Old Central heating system not circulating properly

    The old pump was set at 3 and so I've set the new one to the same. Today all the radiators are equally 'warm' at about 31C which is pretty poor. Tony, Yes I believe one benefit of using 8mm instead of 15mm is for Reduced heat loss, which is exactly the opposite of what I thought I was...

    Lol!! :lol: Yes you're right about the rambling! I just wanted to get as much info in there as poss to give a good picture of what it is and what's already been done...I may have overdone it a little :) I know it could take 4 weeks before I'll know if the X400 actually does anything, but...

    Dryer on spur trips RCD

    On moving to a new(old) house, I added a short (2M) spur to the ring main in order to put my dryer in the cellar. New cable, new socket, wired directly into the ring main MCB of my split CU (Memera 200AD). The dryer display powers up but trips the RCD when a drying cycle is started. I ran an...
