This is the weird bit woody, the heating works very well,can't fault it. I'm planning on upgrading the pipe work to 22mm, but I'm torn/if it ain't broke don't fix it. I rest my case M’Lud!! what's your gut feeling,dick, should I upgrade the 15mm to 22mm or leave it as it is? |

my pennies worth, I would upgrade for 2 reasons, 1. it will be more efficent 2. the pump is under less stress, if a blokes arteries are thin, he gets blood pressure and more likely to die of heart attack or stoke so, give the boiler big arteries and it will be happy and fitter and serve you better,  |

I say it's the case of looking forward - knowing what you know it will play on your mind and cause you unnecessary anxiety!

Of course Tom’s opinion is always valued, and I agree.
Regardless of the current system, it’ll clearly limit the possibility of future extension or alteration to the system.
For efficiency, increasing the size of the radiators, dropping the running temperature of the CH system & fitting some Open Therm controls. Could save you 20-30% on your gas bill with a condensing boiler.

Isn't this an easy one? Inform the customer and let him decide ?

Well, who am I to advise the Great Endfeed !? *** (But my two penneth would be to agree with the others. We even have 28mm going from boiler to pump in our house as boiler in garage and pump in airing cupboard). Would it also make for a quieter system? |

On further investigation I've found the redundant 22mm ,historically ran from boiler at garage to cylinder cupboard at other end of the house with/I believe nothing teeing off it. The 15mm pipe work must have always been there feeding the rads, what sort of install would this have been? It would have been installed in the 1980's🤔🤔🤔

Some strange system's were designed by plumbers themselves back in the day. One guy that I worked for a short period of time would always take his heating flow from the 22mm gravity circulation flow pipe close to the cylinder thus giving the gravity circulation a bit of a boost when the heating pump is switched on. In truth it might of got a lot of those long 22mm gravity runs working that otherwise wouldn't have worked at all. It saved on pipework too......hey, you don't suppose E/F........  ? |

Tell you what c/f, there's about 11 meters of 22 mmm pipe going in my scrap bag soon👍👍👍

Old fashioned ways. Plumbers are notably conservative, if it works why change the way of doing it??!!
I recall right at the start of the introduction of sealed systems( Combi boiler & the like). The old farts were amazed at the speed radiators heated up!! They’d been used to open Vented CH & couldn’t get their head around how a higher pressure system was more efficient at Heat Carrying.
Design too was another thing not considered. A Mears calculator was their only innovation. You could sit with them & explain how doing a Long Hand heat loss calculation would save them lots of money, fit smaller boilers/radiators & reduce pipe sizes.
Even when houses were really starting to be well insulated they fitted over-sized boilers. These big boilers cycling On & Off all day long😂😂.......Crazy bastards were only paying over the odds for materials.
One guy had this figure of the smallest boiler would be 50,000BTU. So a fairly well insulated Semi had this massive boiler!

 update on this job, I've ripped out 15mm f&r and changed to 22mm also added X2/ 22mm lever because the boiler ones has seized and will probably leak if I use force, and can use them to pull a vacuum when work needs to be carried out. Good idea/bad idea on the lever valves? Also I put a video on here(tom did via WhatsApp) while back ,when hot water is running the boiler was making a loud screeching sound! Well that has now stopped since I increase flow and return. im Tring to get my head around how this hot water fault would related to the heating side?  ?? Attachments:
