Sorry to come back and sound like I am rubbing it in, but the problem is not the ASHP per se but poorly insulated properties and a spell of cold weather which many parts of the UK are not used to.

My ASHP has used 13kWh per day (about £4) to heat my house over the last 10 days of this cold snap, and being in the north of Scotland it is even colder here than many other placed.

Eventually people are going to wake up, read and digest the EPC before buying or renting a property, and if it is poor with high energy costs then pay less for the property.

There are also plenty of people complaining at paying very high daily costs to heat their houses with a gas boiler at the moment.

We absolutely would,though as someone else mentioned,being able to find / afford one with a great EPC is going to be very difficult. It seems like D and E was commonplace amongst the many many properties we viewed. It's also difficult to take it too literally because our last house had a terrible EPC too but really was no big hassle to keep warm with storage heaters and a log burner 

Exactly, in rural locations like the place I live there are very few energy efficient houses that aren’t very expensive bespoke builds or new identikit estate houses on tiny plots in the larger towns.

I looked for ages to find a C and that turned out to be incorrect, should have been a D. (but I can get it up to a C with some fabric improvements)

Our Air source heat pumps (fridge, 2xfreezers, 2xair con in cars) don't appear to have these issues 


ASHPs can work in to out and/or out to in....

Are you sure?  All the vehicle aircons I have ever owned have shut down at +5C to stop the evaporator freezing.

Most fridges and freezers struggle on but power consumption increases and in some cases waranty is invalidated...

For comparison, I live in a 4 bed open plan modern new build. My ASHP is using 65kwhr per day to heat the house & water. The heating is on 24 hours a day. Cost £12 a day over last 10 days (got a fixed rate of 18p for leccy).

Can I please ask what temperature you have your thermostat at,and if you vary it much through the day / night? That's a fantastic fixed rate,lucky you!

18C with uplift to 20C in main rooms during evening.
