18kw is way more than you need unless it's a really old cold house.
It depends on what you want. If it's a basic basic boiler then ideal are grand. There's better makes tbh. Most important thing is that you get your system powerflushed (not chemical flushed) prior to installation, get a magnetic filter fitted and make sure it's wired correctly.
Some of the better brands are Ariston, viessmann, Worcester bosch

I would be very concerned at that price, sounds way way too cheap to be getting the job done right.

What should I be asking for as to be done when changing the boiler ?

That the heating system and radiators are power flushed so that they are thoroughly cleaned out.
A magnetic filter is fitted,
That the boiler is correctly wired up according manufacturer's specification.
That the condense drain pipe is plastic and not metal and is run correctly to a gully drain or connected to a correct drain pipe and NOT just left to flow onto the ground.
That the over pressure discharge pipe is piped to outside.
That the gas supply pipe is checked for leaks (soundness test) before and after installation and is correctly sized.
That all the pipework under the boiler is cross bonded by earthing cable and bonding straps.
That there is a continuous earth cable from the gas pipe back to the meter.
That the boiler is commisioned correctly and checked using a flue gas analyser and a printout from the machine provided with a completed installation certificate (RGII Cert 2)
All the controls should be explained to you the heating system checked that it's functioning correctly.

And the above should cost around 2,000-2,300

Worcester Bosch if you can. Have had nothing but great support from them and the boiler is quality. They are based in UK, but send down people from NI to check if any problems free of charge.

I have the 34 CDi.

Yes of course on the brand but 34cdi is probably 3 times too big for the op's house.

If its such quality, why did you need such great support from them? :pac::pac::pac:

Not really, they didn't check a fault, they were checking the installation was done correctly by the installer and sorted it out when they found it was wanting.

So they came from Northern Ireland to check if the installation was correct?

Ya... there were concerns the installation had issues despite me having 2 separate plumbers look at it here, so they sent down some guys to verify it was ok, and sorted it when there were problems.

Admittedly their plumbers seemed to be more clued-in. :rolleyes:

Out of curiosity, what did they find wrong with the installation that two other plumbers and the installer missed.

So a 15kw is sufficient ?

I actually forget although whatever way it was done essentially invalidated my 7 year WB warranty, so WB came down and set things right and made sure everything was fully-specced (even replacing some items the original installers used with more expensive parts... again free of charge).

Also recently I had an issue with an F7 error showing and I contacted WB thinking it was a major fault but turned out to be a blocked flue which I resolved myself in the meantime (removed some debris). WB still insisted on coming down to check it out to ensure there were no other faults causing the warning I was seeing on the boiler.

Plus they essentially did a full service while there (although stopped short of calling it that) and made sure the boiler was still running at 99% efficiency, checking CO2 levels etc etc


Can't fault the service to be honest and I heartily recommend WB if the OP is interested. They may not still be offering the 7 year warranty (I think it was a special deal at the time), but they definitely still have the 5 year.

Have you considered two zones versus one ?
Being able to heat water separately saves €

Check with SSE - they may Stilll give digital Free climote controller
Works for at least 2 zones

Easily

alexonhisown

Electric ireland have the climote free atm, but their engineers have to install it, and u get €175 credit if you switch. They also have energy efficiency incentive credits

Avoid ariston, vokera etc in my opinion.
Ideal and Baxi are ok, somewhere in the middle.
Viessman, Wolf and Worcester-bosch are at the higher end.

You pay for what you get.
Viessman do 5year parts and 10year heat exchanger warranty. I have fitted alot and they are the business.
Very very rare you get any problems with them after, unlike the cheaper models, they end up costing you more money!!

Why would you avoid Ariston?

One of the cheapest boilers on the market.
Was called out to jobs with problems with the gas valve, Pcb board etc not very long after being fitted...
Not an easy boiler to work on either, difficult to access.
All in my opinion of course

I've never had one issue with Ariston. Ive had some with Vokera. Viessmann and wolf are overpriced and over hyped boilers. In fact I've had most trouble with viessmann. Decent heat exchanger but then again if the system is cleaned properly then every heat exchanger is fine. Especially stainless steel ones

Not easy to work on? It's probably the easiest boiler on the market to dismantle

Well, thats my opinion and experience of them.

We wouldnt be plumbers if we agreed on something :pac::pac:

Would agree, that if a boiler is installed and flushed properly. Most do a pretty good job

Why didn't you get Ariston back under warranty on the jobs that needed gas valves, pcbs etc... soon after fitting.

What components gave you difficulties to change.


in fairness I'm being a bit cheeky I have a connection to Ariston, if you PM me I'll sort out some training which might help you down the road.
