I have an alpha cb24 boiler which was installed over 4 years ago,for the last week or so i have been unable to get any hot water,even when the central heating is turned off,i've tried releasing water from the radiators to make the arrow/pointer go into the green band where it should be,it does do this but still i have no hot water

Could the pilot not be lighting?,it sounds like it does light but i am inclined to wonder about this

Can anyone help?,Cheers

Frank,

Don’t be a Frank Spencer, these people require help with heating / water not cynical criticism regards spelling, in plumbing terms, Bog off!

My boiler is reading 3.0 on the bar I have bled the radiators and the dial came down into the green but when I put the heating on it shot back up to 3.0 I cant get a plumber out until next week is it dangerous and should I just turn the electricity off

holy hell what on gods green earth is wrong with everyones spelling, did you lot actually go to school, so lets have an indepth look at this .... the word Sensor is not spelled "sencor" and the word hear is not spelled "here", you lot need to get your spolling rihgt

I have a Alpha CB24 boiler, that works fine for about 30 minutes when central heating is turned on, then turns itself of for about 15 minutes then comes on again for about 5 minutes. The h/w is boiling hot and you can not put your hands in the hot water. you can here a hissing sound from the boiler when you turn on the central heating. I have repressured the system 2 times in a week, and both times there was a lot of air in the radiators in the upstairs bed rooms.

are you getting any heating if so it will be the sencor switch. Its like a half moon black clip with a little white sencor ball in the middle which clips onto one of the pipes inside the combi. I paid 42 pounds and 25 for a plumber to fit it. It was so easy i could have done it. It took him less than 60 seconds to chance.
