As far as I am aware, heat pump systems require larger diameter pipes; main feed pipes need to increase to 28mm (or even 35mm) for the main feed and return and 22mm for as far as practically possible to the radiators. Our Worcester boiler is now over 12 years old and feeds a microbore system. Works perfectly well and is staying put for the foreseeable future.Our new heating system just isn't working. There are all sorts of things it could be caused by but even the installers don't know why. Apparently it happens often in their installations and they think it is because the manufacturer of the heat pump specifies a gel anti-corrosive agent and it takes a long time to dissolve in the water but eventually does do so (seems to be taking weeks for us). This is only because of the heat pump - the radiators could use the normal liquid anti-corrosive. Neil thinks it is also partly due to the fact that the heat pump requires 20mm pipework but the radiators they have fitted are just standard ones with 15mm connections causing bottlenecks throughout the system. May also be that they failed to flush the system through and there could well be debris or just gunge in the system, slowing the flow of water. Could also be that the filter on the system is not one of the magnetic ones we had before but just a kind of sieve , so small particles can pass straight through. Neil has spoken to the man who designed the system for this house and he thinks it will sort itself out in time. Meantime we are back to using electric heaters. I want my old oil boiler back. Neil's talking about installing an in-line water heater in the kitchen.
Apparently these systems are still new enough for designers not be be very clear about what recommended standards should be, never mind stick to them. This shouldn't be the case - heat pumps have been around for long enough for there to be a regulated standard.
I blame the government, but which one? UK or Scottish?
Worcester boiler, where have you gone? Please come back.
I am hoping that tomorrow's fbg will still be ok. If it is not - it was still worth it.I wish!
The oil boiler worked very well but the oil as very expensive and likely to become even more so, so when the chance to install this system with a government grant to assist, we jumped at it (my brother used to design these kind of heating systems and his did work). Wish we hadn't. It wasn't done on the cheap, but we've ended up with an inferior system.As far as I am aware, heat pump systems require larger diameter pipes; main feed pipes need to increase to 28mm (or even 35mm) for the main feed and return and 22mm for as far as practically possible to the radiators.

Heartbreaking @JohnEGreen.I know that there is need for housing but down the road from us they are building ne housing on what had been a haven for wild life despite many objections from locals there were badger sets foxes wild birds and in summer it used to be alive with butterflies I and Melody would go down there and wander for hours with taking photos but all that has now been destroyed and yesterday many locals were dismayed to here that a young badger had been run over and killed while trying to cross the road next to the building site.
Well done for getting your HbA1c down.Sounded like a very good morning @Annb
We have a Worcester boiler also and I think ours will also stay put for the foreseeable future.As far as I am aware, heat pump systems require larger diameter pipes; main feed pipes need to increase to 28mm (or even 35mm) for the main feed and return and 22mm for as far as practically possible to the radiators.

You wouldn't think anything would kill a laylandii. Hope the magnolia tree does much better.31.05

Managed a little work in the garden, trimmed round greenhouse, hopefully discouraging slugsfrom entering under the cover of grass. Will find out in a few minutes. In the evening rewarded myself with a half hour outside after a long day cleaning and shopping. Need to finish trimming round the potato bed, started last night, and fill the two window boxes. Also buy plants to go in them. Many seeds are failing to germinate this year. Perhaps because of the unusually low temperatures. Whatever, I need
something to plant there today. I like to use herbs for their supposed fly detterent qualities. But maybe something a bit more colourful this year? MrSlim has bought a camellia and an acer so ericaeous compost on the shopping list. The little magnolia tree is already in situ. Hope it does better there than the previous occupant of that spot. What can kill a Leylandii? It was planted there about four years ago but just died over the winter for no reason that we could see.
Must put parsley on the shopping list for today. Slugs or snails have eaten all my seedlings.
Edited to add: There is a hare in the garden. Its peacefully washing it's face. Seems a shame to disturb it. One of the things I really love about this house is the opportunity for wildlife encounters.
I do hope that you can get the installers to sort your heating out before the winter @AnnbThe oil boiler worked very well but the oil as very expensive and likely to become even more so, so when the chance to install this system with a government grant to assist, we jumped at it (my brother used to design these kind of heating systems and his did work).

We planted one leylandii to see how it would withstand the climate here. That was something like 45 years ago. It died back, dried out by the wind but I didn't take it out. It stood there, brown and horrid looking for a year or two but after that it sprouted some green at the top. Looked ridiculous but I hate pulling out anything that has some life in it so I left it there. Now, it is tall and green and does withstand all the wind that our climate can throw at it but it is still brown at the base - that part never recovered. Doesn't matter too much because it is now surrounded by other greenery so you can only see the bottom of it from certain angles.You wouldn't think anything would kill a laylandii.

It is lovely that your garden is a haven for wildlife.
So do I. Neil keeps thinking he can sort it out if he can master all the technical switches and electronic bits and pieces. I don't think he can and want to call the installers back to fix it. I'll talk to my brother about it when we speak on Sunday. He might have some idea.I do hope that you can get the installers to sort your heating out before the winter @Annb
Really good that it recovered so well @AnnbWe planted one leylandii to see how it would withstand the climate here. That was something like 45 years ago.

Yes, I think that your brother will have some idea of the best way forward to get it fixed.So do I.

Going to Chesterfield this afternoon to pick up my new car ordered it late last year so something to look forward to today.
