Air Source Heat Pump running it efficiently

Mstty

The truth is we can all state what suits our particular house, in our particular region of the country, on our particular install (designed from new or retrofit) and the time we have had control of the system.

The reality is you need to spend some time with your controller with several cups of tea, over several days (ideally with the same weather conditions) with a spreadsheet.

What I have got from this and other threads is some good pointers of how to run our ASHP more efficiently which is key this winter with energy prices.

Now for the big question our ASHP is a Mitsubishi unit and you can get an extended warranty that includes service, remote monitoring and free call outs and fix if it develops a fault. For £35 a month we are seriously considering this.

£35 a month seems hugely expensive; about twice what I was paying for the service plan on my old unreliable oil boiler.  I'm expecting my heat pump to be a lot more reliable than that was and so far it has been.  I recommend you find a local heating engineer who can service your heat pump and who you can call out if necessary.

Well we can do this but I don't see that anybody positing on this thread actually has, all the advice her looks fairly generic to me.

Yeah I'm 50/50 on the warranty as they will replace with a new unit. Not sure with all the pipework obviously in place how much a replacement unit would be if I put the £35 a month away for servicing and repairs or replacement.

As for your other comment highlighting in bold when my next paragraph said "this and other threads" seems a bit weird but then again everyone's different👍

Each to their own perceptions of weird, I guess.  I cannot evaluate the quality of the advice you received on other threads but @matelodave has had a heat pump for many years and I would rate his opinion.  I'll discount the advice I gave because I'm bound to think that is good, am I not?

@matelodave

Thanks for your post very informative.

Last winter was our first in the house and our first ever ASHP so I manually set the temp depending on the weather (manual compensation curve in essence).

What we did when it came to night time was have the heating for downstairs scheduled to turn off an hour before we go to bed and then start up again 2 hours before we came downstairs in the morning (effectively off for 6 hours).

In our minds that was a more efficient way of running the system or would we be best leaving it on for those 6 hours?
