DO I NEED 10 AAVs

[PEDRAMALA]

JUST HAD A NEW VAILLANT 837 COMBI BOILER FITTED.
THE FITTER HAS BLED THE SYSTEM TWICE AND NOW SAYS I NEED 10 AUTOMATIC AIR VALVES TO BE FITTED IN THE HIGH SPOTS OF THE PIPEWORK. AM I BEING FED MUSHROOM MANURE.
I LIVE IN A 3 BED BUNGALOW

Seems excessive.

 

[gasafengineer]

Not uncommon to see these in loft space of bungalow where heating pipes have been thrown in , most probably the 'installer' has run main flow/return close to ceiling joists & branched off @ a higher level to radiator drop downs , it might be better to re-run pipework in loft to eliminate the need for all these AAVs.

STOP SHOUTING!

But probably not.

 

[adlplumbing]

you don`t need that many aav unless major problem on the pipe work

I do hope this instraller was cheap!

He is clearly a nupty!

Any competent installer would have been able to identify any potential problems BEFORE he fitted the boiler!

You should ask him to do whatever is necessary to sort out the problem BUT all at his expense!

Do not pay him anything more. If he refuses then tell him that you will be getting another installer to remedy the problem and then claim the costs from him, if necessary via the courts and that will have the court online fee of £60 added.

Hopefully you chose a bona fide installer who is gas registered and you know his name and address for the legal procedures?

If you lived in my local area I would assist you with the procedures for free.

The 'nupty' here is the original installer , if changes to pipework are necessary this would have too of been paid for in any case , if a sealed system then air locks possibly won't be an issue once system is bled & pressure maintained............YOU are too quick to critcise other installers most of the time on here , many times you give out incorrect info & don't have the balls to admit it......................why would you help with legal proceeding against another installer who had no influence regards previous installation? , this is not a place to tout for work.

For starters what is the problem??? For the need for the aav's in the first place is the boiler locking up or can you hear it all rattling about, cold rads?? Was it powerflushed? 837 in a small bungalow? Sounds oversized! Vails don't like not being able to dump excess heat, has it been range rated? Like the others say agile is trying to get work on hear all the time I see as of late!

Old boiler packed up, new one fitted and the far rads were staying cold, system was bled all o/k and after 1 week turned off. When it was restarted same rads were cold, system was bled and rads became luke warm, fitter checked the highs and lows of pipework and diagnosed the need for 10 AAVs.

No noises.
I do thank you all for the attention to this enquiry.

10 aav's is alot sounds like a air pocket so some would help, has the installer shut the hot rads down to force the air out of the returns for the cooler rads?? Also sound like it needs to be balanced and set up a little better, I would prefer to use Manuel airvents in a roof as once the air is out circulation should continue, also auto aav's if the system is a little dirty tend to leak after time costing you as buy the time you see it it's to late

I think that in this case you have been too quick to criticise me rather than taking time to read what was said and I doubt that you will admit it or apologise.

The OP clearly explained the situation, even in capitals, and only mentioned the original fitter and no other person.

Whilst perhaps you have lower standards, my view is that an installer should have the necessary experience to examine what is required, install the new boiler and do everything necessary to make the installation work.

Clearly others who have replied above know the need to bleed loft pipework. I am surprised that you seem not to and apparently think that its acceptable to quote a price and then add extras to make it work properly.

I dont see why you suggest I am touting for work. I said that IF he was in my local area and needed help dealing with the situation then I would assist him free.

The OP has stated this was an existing installation.

Lower standards? , this from a so-called RGI regards an open flued appliance & to quote YOU "the nearest part of flue should normally be 600mm from the house wall" , how many of these installations have you signed off?

Read my post again , i said air can be bled via drop downs so AAVs may not be required.

You often tout for work with the £1600 for a boiler replacement along with the £89 call out/diagnosis fee.

Most times your terminology is all wrong , deffo someone who came into the gas industry later on in life.

JUST HAD A NEW VAILLANT 837 COMBI BOILER FITTED.

Er... how do you interpret that as an existing installation?

He has only mentioned one fitter!

Perhaps you need to look at Ebay to see just how cheap some people will install boilers for!


"""The boiler i like to put in is a vaillant eco pro 28kw combi boiler this is a reliable A rated boiler which is in my words the best combi boiler you can buy at the moment it will heat 12 radiaters and have a good hot water flow rate of 11.6litres a minute. My price is to do a combi for combi swope which includes a horizontal flue, timer and inhibitor to boiler manufactures instructions and to gas safe laws.

I do these installations all the time and this should take a day to do. I do these installations all over the UK.

I also do any other type of installations traditional systems to combi boilers which usually cost £1500. Also a combi to combi change for a 24 kw Vaillant ecotec pro is £1195"""

[hansthebear]

agile, you quote inexplicably low prices for boiler changes all the time.

the OP stated his old boiler packed in, and he had this one fitted, thus existing pipework and rads.

A couple of manual vents and a bit more time spend filling and venting including shutting down rads etc will most likely sort it

I'm not in the habit of supplying cheap labour hence the reason the domestic gas industry is in this mess , plenty 'bods' out there quoting cheap prices only to get their foot in the door & ask for more money half way through the contract , the cost of a Vaillant with flue & clock is around £1000 , MOST existing installations will require TRVs & room stat to be fitted , running the condense waste can eat into the job (32mm) , not forgetting chemicals & time involved flushing , wireing too , oh & 90% of the time gas supply has to be upgraded........ALL this just for a combi SWAP..............then you get the conventional boiler being swapped for a combi , more time & material involved , ALL THIS FOR £1600?......my guess is you get your foot in the door with these rediculous prices only to tell the customer the cost has escalated due to all the necessary EXTRAS involved. .............when was the last time you fitted a DECENT boiler for £1600?
