Hi there!
I've got a Baxi Combi 105e (not instant) and within the last couple of days it appears to have developed a fault with CH.
The HW heats up OK but the radiators are not getting hot and you can easily put your hand on them with no burns.
I checked the boiler and the pressure showed 3 bar! The manual states normal operating pressure is between 0.5 - 2.5 bar.
So, I call in British Gas (I'm on their Homestart or whatever thingy!). Engineer turns up today (I'm at work at this point & my wife's at home). He looks at boiler and after a couple of hours (needed a routine service anyway) says he's fixed the boiler, tested it and it's OK. He also said that the radiators have lot of sludge and it would be best to have a "powerflush" fitted to alleviate - £780 to you guv!
Fast forward to me getting home and radiators are still lukewarm! What gives?
So I look at boiler and pressure is still at 3 bar!! Quick call to BG and someone's coming back tomorrow!
Now to the crux of my post:
What is the correct operating procedure of the boiler for CH? When the CH "kicks in" the orange flame neon lights up. The red temperature neons light up to 80 degrees. After about a minute there's a click and the neon goes out. The red temp neons then go out till the 30 degree one stays on. This cycle repeats ad infinitum but the highest neon that stays on is 40 degrees. Is this normal? I must confess that before now I've never really looked at the panel, but I would presume that the flame would stay on and the neons would continue to rise and stay on to a higher temp?
Also, powerflush for sludge. Is this for real or just a way for BG to get more money?
Any thoughts would be appreciated! Sorry for the long post.
