Hi, I'm looking for some advice please, we have a new build house (detached 3 storey), and I dont think the heating is very effective.
Basic prob is that If we set the stat to 20 degrees it don't cut out! I have had heating on today for 4 hours (raising temp in hallway from 17 to 19 degrees), it seems to me the heat is being funneled up the stairs.
The thermostat is in hallway, (which is approx 6m x 2m long with steel front door at one end and stairs at other), and the rad here is rated at 2109 btus. The rad is by the front door and the stat is on the opposite wall at the stairs end.
The other complication is that the system has two zones with the 2nd and 3rd floor controlled by a stat on the 2nd floor. However the landing on the 2nd floor appears to be getting heated up from below so need stat up here to be set at over 21 degrees to enable the bedrooms to be heated!
I have looked at some rough rad size charts and some of my rads appear to be far too small.
sorry for the long post (I hope it makes sense) any advice would be appreciated.
