Firstly, I like the Intergas. There is a plethora of boilers out there. Some say only the Intergas as it only has a few moving parts. Fine, that is their `opinion`, not `sound advice`. No one is castigating that valid `opinion`, and a video was posted, not by the pros, promoting that product. Discussions emerged about its plus points.
But there is another combi that also has 4 moving parts and a video was posted on that as well. It modulates lower than the Intergas, the poor modulation of the Intergas the pros admit is a negative point, and it has quality 3rd party components. It is also very well laid out inside as the video showed. This was given up to the thread for interest. It emerges that the backup is poor, even though the product may be good, so a useful positive for people reading emerged from that. They can make a valued judgement. I find it amazing anyone could become annoyed over that.
