Hi,
I've just bought a large house complete with an Ideal Isar HE30 combi boiler fitted. (Yes, I know they are rubbish! We had one in our previous house, lasted no more than a couple of years before being switched for a Vailant but that's another story.)
When we bought the house, all the bedrooms had very small radiators (2 ft by 1 ft roughly) which weren't doing much to heat up the large 14ft x 14ft rooms (10ft ceilings). So we switched them for larger radiators and hoped the boiler would be man enough to push them. We also added a large double rad downstairs in one of the living rooms which previously had no heating.
With the heating switched on, all the ground floor rads get nice and toasty but upstairs they are cold or warm at best. I've bled the system of air and pressurised it to just above 1 bar, all TRVs and lockshields are wide open. I've also heard about balancing the system but doesn't that refer to where its hot upstairs but cold downstairs??
I've attached an (incredibly accurate) diagram of my system. Help please, winter's approaching!
