Boiler been replaced

Big Nelly

Hey Guys

Hope you can help, was talking to a friend of mine today and he is very confused, doesn't use boards and asked me to post.

So he bought a house few years back, in Dublin area and gas installer, boiler is in kitchen and the way he tells it the boiler is on the wall in kitchen and there is a pipe running from it, 3M, to get outside. The flu pipe. Now he had plumber in and said boiler was crap one and needed replacing but he would also have to move closer to window. He read the regulations? and they say 3M is fine. So he rang around and a few guys said all the same. Boiler is still running so he left(that was last year)

With the increase of gas he said he would look at getting the boiler replaced in case it was wasting gas etc. He got a guy in who said the pipes etc where ok and he didnt have to move the boiler. But to change the boiler he would have to pay 2,500?????

That seems mental to me, he is not sure of what type of boiler but must be a huge one for that price. I heard the Baxi Megaflow are good? what would you recommend and how much to install?

I know I got gas into house when I changed from oil and to get the whole things installed including piping etc was less than that. He is not going for grant or anything.

Is there anything wrong with existing boiler?

Get a few more installers in to quote. this will give him a fair idea of what the standard price is.

Boiler is still going, I was telling him to just keep it going till it goes

2500 seems a bit high but it's hard to say with out seeing it. Maybe the gas pipe needs to be upgraded for the new boiler! also see this post for a good boiler

rightjob!

2500 is a bit high if its a direct change over!
the gas pipe would not have to be upgraded for a new boiler changeover..
his old boiler would not be as efficent as a new condensing boiler,volkera do a good range of condensing boilers!up to 90% efficent..if you would like a price send me a message

The flue could be costing 300 euro or more ,depending on what fittings are needed and what brand.

Immposible to know that typing on a computer. The main could be running in half inch from the meter supplying a fire too. Also maybe a plume kit is needed due to obstructions and flue clearances. I've serviced 4 new boilers this week where the inlet pressure when running had dropped by 5 mbar on three and was down to as low as 8mbar on the other when running. That's 4 decloration of non conformance certs gone in to RGII today. These boilers were put in a year ago and there are other similar stories from colleges.

I know that vaillant boilers will have between a 3-5mbar of a drop when you test the inlet pressure while its on. This much of a drop is still safe as it has been tested and signed off by the M.D of the company. Its got to do with the restrictions in the gas valve.
I'll have to find the letter we received from the company to show you this. so much for the text books!!!!

3-5 mbar drop maybe safe on their boiler, but what about the other appliances that could be on the same pipework?

Ideal claim their new HE boilers will tolerate down to 14mbar!

JohnnieK

A Viessmann Vitodens will work safely and within parameters down to 13mbar but the regs state only 1 mbar of a drop is alowed and thats what we are all supposed to work too. Already plans are a foot (apparantly) to change this at the request of a large gas service company to a inlet pressure of 15 mbar, and no dout RGI will bend over for them:D

What's the question? Is it "what is the minimum working pressure for a appliance at which it can run" or is it "what is the minimum working pressure allowed by Gas Regs on a NAT gas installation"

I have never understood the ease at which a basic and simplistic regulation is ignored, a gas engineer should have no issue with designing a installation that meets the 19 mbar minimum, some boilers will work at 11mbar, so what, does that mean you fit that boiler because you can't do your job properly? Most boilers I test don't achieve the minimum:mad: and their not Vaillant.

Micky Dolenz

Aren't regs short for recommendations?

While I'm venting, where have these gas fitter come from who refuse to cut a flue to size, is there a mass breakout of tennis elbow, these flues stick out so far someone might lose a eye:eek:

:P

Op I would keep the boiler and spend money on insulation and update heating/hot water controls ie.. Zoneing, TRV's, cylinderstat etc..

Had to replace our boiler last week. Cost was €1800 fitted.

I suppose its always back to the Manufacturer Instructions:D

true, but warranty is void if a 1/2" supply is used and Davies are talking about charging warranty call outs to the installers account if a 1/2" supply is discovered.

A while ago i went to a 24kw combi with a 10 mm supply and a working pressure of 6mbar:pac::pac:

DGOBS

Had a baxi system on 6mbar! (still hadn't turned on the 5 ring range on the same pipework!

As regards 813 being 'adjusted' to suit a pressure loss on pipework sounds a bit like the tail wagging the dog, all fun an games until someone dies

I remember one thing that was said to me years ago. “S**t flows down hill and you get paid on a Thursday” That’s all you need to know to be a plumber.

What I would suggest is only get a plumber that a friend or family has recommended.

My boiler was making a lot of noise. I called 3 plumbers who all told me the boiler needed to be replaced and I was quoted between €1650 and €2500. I will complement the guy (not) who gave me the quote for €1650 as he diagnosed the problem and quoted over the phone. This was back in September, this week when I turned the boiler on for the winter it was running but I was getting no heat.

I than got a guy who had done work for some people in work. He called out gave me a quote for the job, €2000 but he was going to do extra work for that. He than asked why I wanted to spend the money and I told him I was told it needed to be replaced and it was not working.

The noise was air which he sorted and the no heat was one of the other plumbers had turned off a value at the back of my cylinder. (I am sure this was to confirm the boiler was broken).

Now don’t jump on your high horse about tarring all plumbers with the same brush I know there are some out there that are good but my experience shows 75% are cowboys.

Rant over.

Well said, cbrlover !

From this thread we can take that these cowboys are happy to boast about their ignorance here on the forum.

0.6 millibar or centibar or decibar or whatever, they can't read, they don't know what they talk about, what the heck is a decimal system, all this foreign language ....gimmy Oirish meassure...

There seems to be no pressure from the consumer side when it comes to quality staff delivering excellent installations.

What type of boiler was this? How long did it take ? Was the boiler supplied by the installer?

Hey guys

Got some more info, no pipes been changed, just been told he needs a new boiler. They are quoting for a Glow Worm but the boiler is only a 19Kw.

To me 2,500 to just switch in and out a boiler is f**King mental money!!!!!

Micky Dolenz

I've met 10 solicitors, 9 of them were really expensive and talked rubbish, one was reasonably priced and actually listened to me.

I can now conclude 90% of solicitors are over priced hacks.

Actually, on reflection and reading back over that, it sounds ridiculous.

The Glow-Worm is one of the cheapest boilers on the market (there good though) so I would say it's a high price. Did you say there was 3m of flue before it exits the wall?

Yes, according to mate it is in press and there is 3m from boiler till it exits the wall

Well there's 3 1m length's flue extensions straight away which will probably cost around 80 each, sorry did you say he was going to move it to the external wall? If so there's a good cost involved in that and it would probably be cheaper the run a flue.
