www.bbc.co.uk/news/science-environment-66033199We don't seem to like them as a nation do we? After working on the maintenance of them fitted in social housing properties my final conclusion on them was "If you can afford to heat your home to the governments specified temperatures using traditional heat sources then you will save money over a full year by switching to an heat pump". A sort of you have to be able to spend it in the first place in order to save it.

Thats always been my way of thinking Tappy, when I see an advert for saving 30% on an item . I think, I can save 100% on that item by not getting it, I was born in the 1950's and no one had heating at all, A coal fire would be lit at night in one room only and . even then Mum would count the coal used and ration it,,,  |

Like Tom, I too was born in the 50’s. I remember frost on the inside of our bedroom window during the winter. Only two rooms in the house had any sort of heat. The living room had the coal fire and the kitchen was only warm if mum was baking and the oven was on. 😉😉

Ice on the inside of the Windows & coats over the Bed Blankets in the Winter too. Wearing shorts to Skool Summer & Winter. With a big hand-me-down Duffel Coat. Piss Pot poor, but didn’t know it, all the kids were the same. One kid in my Skool class had his clothes from the Army & Navy Store, he was 12 before he realised he wasn’t Japanese General!! |

A sort of you have to be able to spend it in the first place in order to save it. What a load of bollox as usual!! It’s Cart before the Horse as usual, most UK homes are inadequately insulated for Low Temperature Central Heating Systems. In fairness, lots of Local Authorities & HA’s are really leading the way on insulating their Housing Stock. But that’s leading to other problems like Dampness & Condensation. Too much moisture being generated in modern homes & too little ventilation. Ah, I see Skater Boy Adam Chapman got a mention, don’t know who’s knob he’s sucking in Government, but he’s getting all sorts of Grants for his Mickey Mouse Course. I’m having a sabbatical next January, so I may jump on the Heat Pump Cowboy Band Wagon, they’re making serious money💷💷💷💷!! On installs. Two months ago I was offered £2K/week job doing HP installs. I told the guy to fuck off, I’m not taking a pay cut for anyone!! |

Nowadays everything is so insulated that all the young ones have asthma and are allergic to everything. No fresh air. Or maybe I'm completely wrong  |

No you're not wrong cinders, the kids all have made up illnesses now, usually one that gets the parents a benefit allowance, We had more illneses to fear, polio , diphtheria, rickets, head lice, thyphoid , smallpox , and others but skool was never missed and woe betide if we came late, the cane was a great deterrent for bad behavior, not medicine and free meals, Later in life when pressure to get a job done was stress,,We did't claim time off and cried, We had to dig deep and get the job done and if we did't,, BOOM you were chucked off the job,,  |

Yes Tom, dead right. Exactly, everyone has post traumatic stress disorder now.
Nonsense!!

There was no shortage of Ventilation, all the Houses were as draughty as hell!! High winds outside & the closed curtains bellowed in & out!!
I recall doing CH Heatloss Calculations in the 70’s. We would include 2 Air Changes an hour.

Or maybe I'm completely wrong Too right there Dick, there's been plenty of mouldy and damp homes in the news over the last couple of years, however, this is exactly what you get with too much insulation and no ventilation. The mould is harmlessly in the air we breath yet when it finds these high humidity conditions it sets about breeding at a tremendous rate (it's having the time of it's life)  ! Still look at that table and were we are in it, we must be doing something wrong! The only other answer is that the UK climate is not suitable for heat pumps! |

I think our climate is OK for Heat Pumps cf.
Many miss the obvious, a HP operates at its optimum at lower temperatures, so it requires a Low Temperature CH system.
Now Low Temperature CH will heat most homes & there’s very few days were it’s below 0°C in the UK. The efficiency of any HP is taken as SCOP, which is ‘Seasonal’ COP - on an annual basis.
Geothermal HP’s are best performance wise, but these are difficult, expensive systems to install.

When you think about it installing heat pumps in social housing properties were most of the tenants have not got the money in the first place to heat them to the governments recommended temperatures was not really the smartest of moves!
It's working on the heat pumps fitted in these properties were I've got my mainly negative experience of them, yet the odd tenant would be very satisfied with the system and have really hot radiators.
I've said before, for me, the jury is still out on these things
Having said that I'd love to have one in my own home (just to experiment with it).

My sister, lives in Truro. The council fitted one of these systems in her bungalow a few years ago. Never worked properly from day one. Kept losing pressure and stopping. After almost 18 months of constant complaints about it not working, they sent another company to have a look at it. Finally fixed. The chap who worked on it told her he’d never seen such a poor installation. Leaky joints, poor routing of the pipes. Took him almost two days to correct it. Now ( apparently) it’s working fine .

See for Heat Pumps, you need limited valves & lots of circulation.
So it’s huge Flow Rates & Low Temperatures.
Delta T of 5°C Flow & Return need bigger bore tubes too!
A HP system needs to be carefully designed.
