Another boiler

[Dapph2]

Daughter inherited grannies house recently. Heating is knackered. It has a leak on a brass valve bit. Repair man says its not cost effective to repair. Its an ideal logic of 2012 vintage. It was installed during one of those campaigns headed by johnny ball that ripped off old people. The previous heating was the old back boiler type installed by council in 1984. Anyway it still has its original radiators and microbore piping.
Daughter has no money so I'm paying. What can I do myself to reduce costs. I suspect its pointless trying to keep the rads and pipes, nothing has been serviced or flushed ever. Can I just rip out the old microbore and put plastic or could the layout be different considering this layout was for an old system.

Daughter has no money ? I she eligible for a new boiler heating grant or financial help as the old boiler is now 12 yrs old & often come into the government warmer homes replacement schemes , My 39 yr old oil fired boiler was microbore and all piping was removed as it is not effective in getting enough water to the new double rads . All new 15 & 22mm pipes were surface run through the roof void ( we have a large bungalow) , where they did have to drill the walls there was very little mess on our two day old new carpeting which was easily sucked off by my heavy duty vacuum cleaner .
We have had to have two more boilers ( one every 12 years or so since it was installed as the life of the more efficient oil fired condensing boilers is a lot shorter than the ancient heavy cast iron and steel plate heat exchanger models . Changing the boiler & insulating well had seen us reduce from 1200 litres of heating oil, three times per year 3600 litres to just over one tank of 1200 litres ,
I got rid of the letter box in the door as well ,which also made a noticeable difference once we had an external mail box put on the outside wall

Tried to see if there was any schemes to replace last year when granny was still with us. The only one going is ECO4 which is based on the houses EPC rating. And its based on the boiler efficiency rating irrespective if it works or not. They would of 'topped up' the cavity insulation, but then demanded they drill holes in every window frame to add trickle vents.

If it's microbore it's probably a newer flow and return system but if it's a single pipe system it might it be worth replacing it all.
Pull up the floor by a radiator and see how many pipes pass it, if it's one pipe with both radiator pipes going to it it's a single pipe system.
Plastic pipes under a floor? no thanks.
I was paranoid about mice eating it and causing an unseen flood in my house so I used Kuterlon plastic coated copper pipe in 25 meter lengths.

There's no joints under the floor anywhere and unless there's a very hungry rat down there should be rodent proof.
I used manifolds on both sides of the hallway to terminate the pipes, it's proved to work very well so far.

as goes for underground heating or heating a solid floor theres no way id want crap, silt inside of those pipes

so id fit in a mag filter cleaner before they enter the floor and periodically clean it well

once that system fills you lose the underfloor heating and your back to rads on the wall

I haven't got underfloor heating Gaz, it's all radiators, all brand new and I have a Magnaflow filter on it that was clean as a whistle last time I checked it.
Works well for me and the cat likes the bit of floor the pipes are screened into

Trickle vents are brilliant as you can close them shut if its not wanted .
Our vents are very variable , since having them we have had very little condensation problems
