Firstly hello this is my first post.
The back ground: I recently bought an old house. The heating system was intact but the boiler wasn't working (heat exchanger leaking).The boiler was replaced with a straight replacement Ideal Condensing boiler. At that time there were no radiators on the walls so a system balance was Impossible. Now the house is getting something like finished I found I was getting astronomical gas bills.
From Instructions found on this site I set about DIYing it. Im an electro mechical engineer in a Glass works so I can manage to follow instructions and have Multi meter with thermo couple Input as a Thermometer.
First Question: To achieve the 10 to 15 degree Drop across the rads every lock shield is almost closed. They are the danfoss ones with an Allen screw adjuster. I would say that none are open more than 1/8 of a turn. Is this normal?
Second Question: I can only just achieve the 55degrees return leg temp (for Condensing) at the boiler and the pump is running at full speed. To Get this I have to set the boiler to no2 on the boiler stat. With the boiler at full heat I get around 75deg out 65 return. Is the pump at fault? If so why am I having to restrict the radiator lock shields so much?
Thanks in advance for any help.
