Alpha CB24/28 - CH working fine but minimal hot water

[Leigh-B]

The actual model is a CB28, sorry i should have said earlier, i didnt look at the front of the boiler just the instructions i had for it.

Did anyone see my comments about the noise now coming from the actual gas meter since this fault has occurred? could someone confirm if i should call British Gas out about it? It sounds as though the gas flow is restricted, but if it was im sure the boiler would indicate it by flashing a light no?

A hissing noise does not sound good but you could call 0800 111 999 anytime for a check. Are you sure the water main is not near the meter?

If 2 or 3 of you guys say its the same thing then when i call a plumber round i will be more inclined to pay for the items you have mentioned to be fitted. If the so called plumber then tells me i need this or that replaced too then i'll tell him to get on his bike......

Firstly, I think that you should be calling a "boiler engineer" rather than a "plumber".

Secondly, you should be paying him to fix the boiler! Not for changing parts at your expense which may or may not fix the fault.

Someone who describes himself as a boiler engineer would be expected to have a high degree of technical knowledge and to specialise in boiler repairs rather than a general plumber who fits bathrooms and unblocks drains.

His task will be to diagnose the fault, repair it and take full responsibility for correctly diagnosing the problem and leaving you with a working boiler.

In this case its a simple diagnosis of a failed diverter valve. That can either be replaced or repaired. As I said before, in our local area we would repair for £106 or replace for about £186 both including a basic service.

id get a pro in! ive changed a few and ya have to drain the ch water out of the boiler (as ya have to remove the calorifier to get to the diaprhragm) so i generally change the full valve now. also theres a few screws that can seize in and the low pressure switch often blocks up wen the boiler has been drained! but its not a bad job if ya no wat ya doing on um.. he'd be able to luk at ya meter while he's there!

I think i will yes. The water main is nowhere near the gas meter, i can clearly hear that its the gas meter. Its situated in a hallway and it used to be silent before but now i can hear the hissing when the CH is on.

Oh my god, ive just noticed that my boiler has a built in frost thermostat. I specifically remember the plumber saying i will need one fitted by an electrician, so i had it done. I've even got the bill for it too!!

Just goes to show some people really have no idea what they are fitting eh.

If boiler is in an unheated zone then an external frost stat for the pipework in that zone is recommended, aswell as lagging. Perhaps that is what your "plumber" meant.

I wasn't meaning to be rude about the well meaning amateur's suggestion, but to my knowledge his advise is not useful to you where the boiler you have is conscerned. A little knowledge is a dangerous thing,.

When one of us atttends tou your boiler we expose the workings run a tap and look and listen to it, before we go jumping in with "buy a diaphragm and put it in". In the case of your boiler I fit 20 microswitches to 5 diaphragms to 3 plate heat exchangers to 1 full diverter valve or NTC. You could either get in an expert who with his hands ears and test meter can determine what is wrong and fix it, or you could gamble on the law of probability. But it wouldn't be a gueswork process, we would know within seconds what part was needed and get it right every time, because of our familiarity with the machine.

Not bragging for myself but to put it plainer for you, such a fault as yours is likely to take a person familiar with that boiler about 5 minutes to fix, and mainly that tiome is spent on introductions and nicities and listening to what you have to say, less likely to take 1/2 an hour if something fairly invoilved needs doing, seldome would take a whole hour.

Whereas if you play parts roulette and put them in yourself you will in all probability put in a lot of unnecessary parts and take a few eekends to get it right. Sooner or later there will be an Alphas are cr ap posting followed with can anyone recommend a new boiler.

I had to go to the Dr the other day I could have stuck my own finger in and stirred it round and palpated my own abdomen, using my nursing knowledge and the tinternet I could probably diagnose as well as he has what is likely to be wrong. But what the heck I went to the Dr anyway, he came up woith the same idea as me, and it's off for a camera crew up the one eyed trouser snake asap. I don't think I'll let someone who has had one of these himself once do it thanks.

Once when I had a house to sell I bought a book on conveyancing, read it from cover to cover, and made a mental note, solicitors are worth every penny.

Heating engineers have their good points you know.

Some of the illustartions might be mataphorical.

Paul i only came here for some help, not condescending remarks. Is there really any point to this website if the answer is to call a Plumber every time? Oh sorry Boiler Engineer.

 

[Paul Barker]

you think i am condesending? If your tactile skills are as good as your judgement of human nature or intent to help you bette had get a professional.

You are obviously unaware of the great amount of help that i have offered you. Back to best guessing it with the help of laymen is it?

So what do you call all of the above then Paul?? Just a simple answer would have been fine.

you think i am condesending? If your tactile skills are as good as your judgement of human nature or intent to help you bette had get a professional.

You are obviously unaware of the great amount of help that i have offered you. Back to best guessing it with the help of laymen is it?.

Well yes i wouldnt have said condescending otherwise would i. Sorry buts that the way i took it.

Anyway, the only person who was even close to hepling me solve this problem was 'Gasguru'. The only one of you who told me to check the meter out, and guess what the problem was. The Pressure Regulator on the gas meter was busted.

Thank god i didnt call a Boiler Engineer, who knows how much they'd have charged to tell me to call British Gas, or even worse, replace some of the boiler parts, charge me for it, then tell me to call British Gas.

Well done Gasguru!

 

[DARTHVADER]

Hey, I helped too!! didnt I???

 

[Leigh-B]

Hey, I helped too!! didnt I???

Yes mate you did, sorry i didnt mean that you didnt help. All i was saying was that Gasguru was the only one who suggested getting the meter checked out.

Thanks for your advice!

 

[Gasguru]

Hey, I helped too!! didnt I???

Telling us how you changed a diaphgram on a 240....a completely different boiler.

I shall now polish my halo.

 

[DARTHVADER]

Correct, but at least I bothered to respond. That in itself is helping.

 

[Gasguru]

There's no point in responding with inaccurate diagnosis or remedy, it just drags out the discussion and adds confusion.

Have a look at the recent posting on Elson tanks, almost the whole first page of postings was a waste of time due to lack of knowledge by the those concerned despite Elson appearing in the heading.
