People have moved on - they like the convenience of central heating. Yes we could go back to the days of open coal fires or plug in fan heaters but if the 'vision' of going green and saving the planet is that people have to reduce the quality of their lives then I doubt many are going to want to sign up. If you want to replace gas central heating throughout the land you need to have something that is at least as good (if not better). Heat pumps do not tick that box. So a heat pump is a new type of fan heater, one that doesn't produce 80 degrees in front of itself and rely on heat transfer to move it around the room. It produces a constant flow of gently moving air at 22 degrees. Hence the entire area of my house is a constant 22 degrees summer or winter. Central heating is dated, the idea of heating a radiator to 65 degrees and hoping it will distribute the heat evenly around the room and house is out of date. Sure it was better than a coal fire, but its not better than a heat pump. Why can't heat pumps be fitted on current housing stock, what are the reasons? Can they not fit these on the outside of current housing stock (They seem to manage with air con units.)  can they not fit these on the inside of current housing stock?  Too bloody noisy and takeup too much space. What about our housing stock that have no frontage? |

They suffer from the same problem as fan heaters - as soon as they are switched off the heating effect stops, you have no residual heat. Hence you need a fan whirring 24/7 to keep the temperature up. Now for some people they might not mind the noise but I'd suggest that for many used to the silence and efficiency of central heating that would be a step backwards. Yes they run continuously, but that they make a lots of noise is just a lie. They make less noise than air conditioning. Here, its only 90 seconds. www.youtube.com/watch?v=GKDF5a47eJk |

So Jonksy is lying, is he, Zany? On the basis of a webpage, when he has hands on experience? I must be careful, you'll be reminding me this is in the Mind Zone.  |

Jonksy,
This is a mind zone thread. You should attack a poster's arguments rather than their character. Avoid criticising the poster at all if you can.
There is no limit on attacking an argument with another one

I’ve spoken to several gas engineers and electricians over the past 18 months , some of them who fit both heat pumps and gas boilers .
They have all told me that heat pumps are fine for new builds but not for older houses . I won’t be considering a heat pump in the future .
Also Cadent are busy preparing all the domestic gas pipes for hydrogen gas. They are doing this outside my house now.

Those who are fool enough to have these monstrosity may put up with the noise but I can assure you the neighbours don't. This is one of reasons people do not like them or have any intention of owning one. |

They do make a noise . My neighbour had one and sometimes two running .

Heat pumps are optimal for underfloor heating systems which once up to a steady temperature retain their warming effect even when the system is shut off, say overnight.
And compared to hot water radiant systems which require water temperatures of 60C or more the water temperature in an underfloor system is typically only half that.
The thing that people have to get used to is that you can't turn them on and off with a flick of a switch.
There are very few houses even in the UK which cannot be retrofitted with underfloor heating, and in my experience once you have experienced it you will never go back to an antiquated radiator system much less a ducted forced air system as is typical in the US..

My heat pumps are almost inaudible from 3m away.

There are very few houses even in the UK which cannot be retrofitted with underfloor heating. Not really . Modern homes are highly insulated and older homes are not. Underfloor heating is not particularly efficient either. Heat pumps range from air source ( which are shit for older houses ) to ground source heat pumps ( that are still shit for older houses ). The best heating for older houses is gas . You can get electric combi boilers . I was told by a gas engineer that they were very expensive to run . |

Why are heat pumps 'shit' for older houses? Assuming they are brought up to modern standards for insulation, air leakage, glazing etc.
You'd be foolish to install any form of central in a house which hasn't been updated or built to modern standards in the first place.

If old houses were made into new houses then there would not be a problem . Old cars could be fitted with an electric powered engine and that would cure the problem of fossil fuel engines , right ? |

There is nothing particularly difficult in bringing older houses up to modern standards, it happens every day.
Part of the problem is that fossil fuels were so abundant and cheap that for many years people didn't care how inefficiently they were used as long as they made their house comfortable. Spending money on 'invisibles' like insulation and plugging leaks just never became a priority. But times have changed.
You still haven't told us btw why heat pumps are 'shit'.
