he was instucked to run it 24/7 using the low setting and use the stats to control it, Keep all the internal doors open and it works great, After a couple of days, the whole house was in the 20's just using those instuctions, Women being what they are turned it up, a couple of days later the house was a sauna and no one could sleep even though the outside was -20 C And yeah, it got noisey, So its best used 24/7 on low and in his case it works very well and economical and the bonus is, Its an air conditioner too so, in Summer where they can get temps of 35 degree's C, it will keep the house cool, Ain't that a fact ! In my case they also don't understand what a thermostat is especially a TRV. |

in my case also true despite 5,000 special instructive lectures on Why the radiator turned itself off, She still insists on saying, " the heatings gone off again "  |

Realistically, even here in Jockoland, in the frozen north, there’s very few days out of the 365 days that are actually below 0degrees.
That along with a well insulated house, makes good sense to us Heat Pumps & Run them 24/7.
In the simplest of terms; nobody switches off their fridge before going to bed!!! A fridge will maintain low temperatures, in a compartment that’s fairly air tight & fairly well insulated. There’s no smoke & mirrors or dark arts going on, it’s simple physics & the simple laws of thermal dynamics. Heat will always go to Cold!!

well put Dick, an air source pump is just a fridge in reverse, leave it running on a low setting and its as good as it gets,  |

Heat can go from cold to hot.
All you need is to make a thermal inductor. Blocks/pipes of copper, gyrator, superconducting coils, heat switches, liquid helium, silver paint, thermal oscillator, meters etc, and some electronic bits. 
"While it fully complies with the second law of thermodynamics, we identify a general thermodynamic limit for the maximum possible cooling effect that can occur during such a thermal oscillation cycle."

Noise is a big problem with ASHPs, especially in winter when we get the beast from the east - then the units need to be on 24/7 to keep pace. Maybe we also need a back up form of support heating here in the UK? Early days yet though for these units. Seems to back up what I come across tom, two different people with very different opinions on heat pumps. They think like you Tappy - a system in tandem with the ASHP apple.news/AjarXRkjrRSq3cXqMarqetQ |

You would expect that from Centrica though battle after all it's their industry that's under threat.
A lot of people just want something to turn on for half an hour for a quick warm then off again (it's all a lot of people can afford).
I say fix fuel poverty in this country first.
Only after then we should be talking about heating all our homes throughout the winter to 18 - 22 degrees and then saving some money through heat pumps?
