If they're doing a a full clean of the recuperator in with that £80 its good value.
Intergas...but which...

That's right and as of recently Riello are owned by UTC, an enormous corporation, they own Carrier, Chubb Otis Lifts, Pratt and Whitney etc. etc.

I mentioned it so the poster knows what to look for.
VC, thanks. So all these companies are a part of one super large corporation. The rise of the corporations continues. Boilers will end up like the car industry where the vast majority of cars in the world are made by a few corporations. Hence we see little technical progress in cars, only visual tarts ups with `toys` inside.
The mass market combis may be largely a kit of third part components. That sort of sounds good. I find the `quality` products have better made and designed `one piece` casings that lift on and off simply and quickly. When looking inside the cheaper makers they tend to be a large collection of sharp edged sheet steel ripping hands apart. I recall one boiler serviceman who wore Fagan gloves to protect his hands. Also multi-part white casings put together by self-tapping screws. The layout of the `quality` makers is such that they are easy to change any part. The `quality` makes are also quieter. Although some have sound insulation inside the casing, rather than quiet fans and pumps.

This is a strength of Intergas with their very unique design. 
They were being promoted by Plumb Center with a boiler in each branch near the counters. The simplicity was admirable. I suppose they need to get the burner modulation range higher (modulates down lower) as the next step in advancement.This is a strength of Intergas with their very unique design.
Vokera is getting good press on this thread. I always thought they were more towards the cheaper end of the market with a few decent models amongst the range. Unless they have jumped up a few notches.
Back to the ploy of putting `designer` appliances brands on show like Neff and Bosch. Many of the guys who renovate places around me will use Worcester Bosch boilers. Bosch is a well known make and the estate agent will emphasise that even the boiler is a `Bosch`. People think the heating system is incorporated in the white box. I have seen some that are piped up with only 15mm pipes under the floorboards running to the radiators, 22mm where on show. Subsequently it was slow to heat up and struggled in deep winter. Many kept the system on 24/7 to avoid the place getting too cold when they were out as the reheat was far too slow. The boiler could not get rid of the heat fast enough and cycled.
All interesting information.
I will certainly prompt my brother to get an intergas quote. I certainly think he would rate reliability and a solid design over ultimate efficiency.
As you say, the modulation seems the only weak point.
Other than the intergas, considering modulation, what would you consider as a second choice.
Ironically, my brother, who works in property would always steer clear from Bosch as it became very clear early on that they were very unreliable. Whether this was due to sheer numbers, poor installation or just bad product, I am not qualified to say.

Does the build quality of Intergas translate to their system boilers?
I am also due to replace my 40 year old boiler.....soon. I much prefer a system boiler.
From what I have read and understand, a system boiler is a much simpler beast. Does this mean the variation in system boiler build quality is less of an issue across the manufacturers?
What makes a good system boiler?

They're totally different designs. The Ferroli is not worth any more keyboard time.
They're the range boiler. The combi has the extra 12mm pipe laid into the casting plus the flow sensor and clip on temperature sensor.
In fact we use the Eco RF as a system boiler to give our customers the 10 year warranty and remote management.
The Ferroli is a simple tube within a tube and coiled to form the dual circuit heat exchanger.
The inter gas on the other hand is a complex construction as shown here in a video uploaded to youtube by Dan Robinson in 2013.
Note that the smaller diameter tube is a single length bent to shape. no joints on that circuit.
Compare that to the patent application diagram which shows U bends fitted to both circuits.
That is a large number of soldered joints to be made on an automated production line. No doubt the quality control is high and as a result the production yeald is high enough to make the design cost effective. Failure rate of installed boilers is very low and thus the joints appear to be reliable in service.
The complexity of the manufacturing the Intergas heat exchanger seems high compared to the tube in a tube construction of the Ferroli heat exchanger.
Ferrolli use quality branded main components according to the video. I have read some praise of the Ferroli Modena and after all it is very simple with little to go wrong. And it is quiet. What are your reservations?

Simply put its a Ferroli. I'm not spending any more time discussing how crap they and the company are.
And once again, Bernard shows how little he understands.
Like the Puma and the Wooshitter Si and a couple of others the names of whom have escaped me.
