So what would you consider as being reliable?

Yes mate, but you need to follow the usual rules about expansion vessels and prv's. You can use any of the boilers open vented too just unplug the pressure sensor. Pipe the feed and vent into the return.

Thanks. Looking to spec one on current job. Old suprema (now in the skip) and new conventional boiler in the loft driving 14 rads and a 300L unvented. Customer is going elec oven and induction hob in the kitchen and the gas fire feed capped and buried away so that helps us with the gas supply being just for the boiler! Finally got a customer sold on an Intergas so looking forward to getting one on the wall

If you're using the ov in place of a Suprima, bare in mind the flow and returns need swapping round.

Other than that, with the offset flue, it is a direct swap.

Did an emergency swap out of one in a garage a few months ago in two hours

Cool! Wish it was that simple old unit (was) in the kitchen... new lump is going in the loft; next to the UV we put there five weeks ago... we advised to change and move the boiler up there too... he's now decided to follow our advice 5 weeks later fooked my diary right up!

So I have a dreaded Ideal Isar for 9 years now, its just started its 10 year. In that time it has had the following

1) leaking diverter valve casing
2) Expansion Vessel failure
3) Leaking Diverter Valve casing

The last two repairs were in the last year and bit.

I was just wondering has anyone had a combi condensing boiler run for 10 years without a problem, and what would you consider as reliable? One fault in 10 years?

Thats good for an Isar

Sounds ripe for a Pin5 hot water priority installation to me

I have a Potterton Profile (regular) boiler that was installed in my house in 1989 when new. Its still there, passes its BG check and service every year, usually with a thumbs up from the engineer as a boiler "they don't make 'em like they use to".

I live in a very hard water area and had the house converted to unvented in 2006. the only problem I have had is the PCB which I understand is a common problem with capacitors blowing and I think from memory a valve of some sort in the boiler about 16 years ago. So in 27 years two faults. Thats pretty good in my book and I am not looking forward to its eventual replacement, I'll go for Bosch or Vaillant I guess but the relative simplicty of the old boilers must be a reason, in general, for the poor comparison with modern boilers ?

It may be that Government has made the push to sell energy efficient boilers which leads to making a compromise between building a boiler with reliability as the main focus to one that has efficiency as the selling point?

Is there a tradeoff between efficiency and reliability?

I see new Diesel engines can be unreliable compared to older models that do not meet the latest emissions guidelines, perhaps it maybe similar for boilers.

Intergas Eco RF.

10 year warranty and remote management facility for the installer.

On the website its 5 years parts and labour and 10 years on the heat exchanger and not 10 years for the whole boiler?

 

[bernardgreen]

Is there a tradeoff between efficiency and reliability?

Yes......, because to build an efficient boiler that is also highly reliable is expensive. It has proved very difficult to design a boiler that is both efficient and reliable at a price that the average customer will pay.

 

[dilalio]

And it is also pointless designing and manufacturing something to last years and quickly become non-compliant with the constantly changing emissions targets!

Don't know where you're reading that - it's 10 years on the whole boiler (when installed by an Intergas-trained Platinum 5 installer)

It is the whole boiler. The website is out of date.
