Microbore CH came in quite a while ago.... apart from extortionate prices for fittings, the main objection was noise. The flexible connectors and single-hole mixer taps bought it to the DHW circuit.....not so long since, AFAIK you were only officially allowed a kitchen-sink tap , of the incoming Rising Main....everything else had to be via a break-tank, because, in the event of the mains pressure failing,it was deemed possible that water from, say, a toilet -cistern, "could" be drawn back into the main.....never heard of it actually happening, but , I have heard of a Water Authority poisoning a complete town, due to their incompetence and negligence.
but that was only 30 years ago and a mere 20 thousand poisoned

Putting radiators under windows. Another myth?
The reason used to be given, that it mitigated the cold-draught caused by the air-circulation from the higher heat-loss from glass. Given that most of the population now has double-glazing and properly draught-sealed and mounted frames (even listed/ conservation-area sash-windows can be vastly improved, thermally) Also add the fact that many a closed curtain went over the radiator, thus killing the convection-current in the room , which leaves you with only one surface radiating into the room....lovely warm glass and a big patch on the outside wall, though! Short pipe-runs= quicker heat-up...radiators on inside-walls ,= heat is radiated internally, before escaping through the outside-walls.
We now have plastic piping, push-fit and outside-taps (albeit with a double check-valve) are allowable. Boilers are built, like the majority of cars and appliances, to have a relatively short service-life. At ten years old, most of these pressure-boilers will,or have, failed. The cost of repair exceeds the cost of a replacement, but, as @defcribed has said, it's the knock-on costs that overshadow the cost of a boiler. I'll stick with my 45+ year-old cast-iron one, until the gas-valve croaks and the parts -factors suck their teeth and say, "Sorry,Squire, Don't make them anymore and they stopped the service-kits years ago,......they lasted too long, you see". I think it'll see me out, though!.
