Hi, first post on here so go easy

I have the aforementioned boiler installed by BG approx 5 years ago and has been on homecare agreement ever since. In the summer we had a breakdown, no hot water, took BG a week and three different guys and virtually every part in the boiler replacing before it was corrected, including the exchanger, flu, and numerous valves and sensors and a control panel(would have been cheaper to replace the boiler wiv a new one!!!).

Now over the last few weeks as the really cold weather has started to creep in i noticed the house is nt keeping as warm as i remember and checked the rads and found alot of them half cold. Went round and bled them and took a lot of air out, but in doing so knocked the boiler out on a low pressure warning. No probs i thought just open filling loop tap and jobs a good un. No go , filling tap seized shut. Removed freed of, re pressurised and capped of. Hey presto heating on.

Alas although the rads are hot throughout from top to bottom, the house is still feeling chilly even while boiler on full blast. And you can place your hands on any rad and keep them there without pain! whereas i remember not being able to do that last winter.

Any ideas as the homecare agreement has now finished and we didnt extend it

Many thanks, bit of a long post i know , sorry

make sure boiler stat is set higher

make sure boiler stat is set higher

At risk of sounding dumb, there are two temperature controls on the front of the boiler, one for the heating and one for the hot water and they are both on highest setting. Is there an internal control under the cover? There is no external thermostat in the house

Have had the front cover of the control panel on the front and accessed the main control board(pcb with the two user controls for water and heating temps and LCD), found it was only held down by one screw there should be three! So the outer control knob for the heating temp wasn't actually engaging the board and thus not changing anything, the temperature controller on the board was only at about 3/4 set, so i sorted that and turned it round to full and the temp on the front went from 52 to 55 mmm, an improvement but not by much. While in there i noticed three other adjustable resistors, one of which had an anti tamper device on, They were both set to the lowest point in there range so i adjusted one about an 8th of a turn an hey presto we're in the low 60's another tweek and 70 was showing, also tweeked the other one which has improved the hot water temp too.

Now being it an unknown quantity and having limited knowledge of the temp capacities i have left it at that and i am monitoring as we speak, but the house is cosy once more and only at 8/10 of full on the dial and sitting steady at 73 on the screen.
