Thanks but you lost me in your example. The u value of the triple one is lower therefore better than the double glazed isnt it?

Thanks What I dont get is that I thought DG was supposed to prevent heat going out but most of the B rated windows have a minus energy index. The A's have positive numbers which implies you gain however if I got A would they function at 100% if I dont get much sun

Is A strictly better than B no matter what? I've read somewhere that A rated windows use solar energy to increase heat inside the house however if the house doesn't get much sun is it pointless to get A rated windows? The issue I see with that is that B rated windows lose 6 kWh/m2/per...

Does it matter that I have an oil fired boiler before I run the wizard?

Thanks! I think they must be working properly however our house is always cold no matter what. I have always cranked the TRV up to 6 (MAX) and kept it on that. The TRV may be the right temperature at the RAD but the room is nowhere near that temp. I wonder if I need double/larger radiators.

Does that mean when on 3 and its not 21C then the radiator is goes full pelt until it registers its 21C. When I set it to 2 and it goes cold is that because the room is at the temperature that 2 relates to?

I have a oil powered boiler out in the garage. I have a timer control inside for the water and heating. On all the radiators in the house they have TRV's each with a green circle around number 3. What does that do because when I set it to just under 3 by a few millimeters the radiator...
