As it is at the moment with the locksheilds fully open it gets a differential of up to 17 degrees on initial heat up from cold but as it modulates and reaches near the set temp it goes down to about 7 degrees diferential so I though maybe if the water flow is restricted slightly it would be a...

I decided as you guys say its running as it should I will leave the locksheild valves fully open as the system heats up evenly like this anyway I set the thermostatic valves to an acceptable level (3) and to let the roomstat controll the overall temp of the house it just seemed to me that the...

Yes I have a didpgital roomstat that's set to 21 degrees thankfully So your saying if I wanted to run my heating 12 hours a day and didn't have a roomstat the boiler would be burning gas perminantly for 12 hours that seems a bit unlikely to me what's the point of the boiler having an in built...

I don't want it to turn off I want the boiler to reach the set flow temp and then cycle like it should do not constantly burn gas for 2 hours

Had another play tonight tried balancing again reducing pump speed changed to different temperatures the only thing I found that makes it switch off was turning the biggest radiator off in the living room tried range rating it to 14kw didn't work the total btus of the rads is 36000 the boiler is...

Its set at 65 and is hovering at 65 but even if its set to *ny other temp it still does the same if you turn the temp down by 2 degrees when its at 65 to 63 it stops burning then but if you leave it it will not turn off it has to overshoot the set temp by 2 degrees before it turns of but because...

Ultracom 30 cxi doesn't reach set temperature it gets close and just hovers around it it's been on for 2 hours now and hasn't switched off it is constantly burning gas I've tried balancing the system but then it short cycles it's a 2 year old system and has only started doing this since I...
