Hi i have a couple of problems with my central heating:
1st when my radiators are on up stairs the downstairs radiators go cold Ive checked out a few web sites and its probably a balancing problem so Ive turn the return valve's quarter turn on radiators up stairs but now only lukewarm downstairs so a bit of improvement but not great. If i turn all radiators off up stairs the down stairs radiators get hot.
2ND when the hot water tank reaches temp the boiler turns off even tho the thermostat in the living room has not reached temp.
Please help.
Thanks
Phil
