ASHP & triple glazing

[Joeboy]

Is that DHW and heating combined for the SCOP? I've got my combined DHW and heating at about 3.6 for the year using the GSHP

EDIT:
3.75 for as far back as my data goes.

13th Dec to now combined. The only way is up!

Also you had a lot of data errors due to air in the system prior to 27th January, if you take the cop since then it is 4.59 so will only get better as the temperature (hopefully) improves.

Cheers Iain, great to know! You'll soon be at your 1yr mark?

I've just moved the DHW to 10.30 to 12.00 to see if ambient daytime temp makes much difference in dropping the 24hr kWh consumption.



I am blown away by the consistent performance. Had a couple of 7.+ cop figures earlier today.

I did start with my HW cycle during the cheap rate until I got my additional batteries then changed it to midday, easier on the HP when the ambient temp. is higher.

Yes it's nearly a year, my monitoring went online on 9th March and apart from the first week or so when I had a setback programmed during the night and a WC curve of 0.6 (too hot!) it has been on non-stop at either 0.35-0.40 WC curve.

That's great to read. The in/out figures are hard to grasp although I can dial right into the whole house temp being even. That feels luxury/tremendous.

Yep, not that it's a competition. I'm 3.49 over the same period. It interesting how the GSHP and ASHP performance at temperatures is opposite. The GSHP will perform better in extreme cold but for example at the moment the ASHP significantly out performs the GSHP. It will be very interesting to see your data after a year is out. One day my HP will die and then I need to decide if I will stick in another GSHP or convert to an ASHP. With technological improvements it sounds like ASHP might be an easier option.

We are also looming forward to the 1st year figures. Of course I run wee scenarios in my mind. I was surprised by how quickly we got in line on the WBS and that 75% drop means I've got 8 to 10 years logs on standby!

You are right in that it's not a competition as we have wildly varied properties, demand lifestyles and geographical location variance to name but a few.

I'll say I hope for a 50% drop in power bought and for parity let's say a 50% increase in income from the export contract jan to Dec 24/25 comparison. TBH, I'm a little indifferent as I know we are now in a good position for us. I'm not going to game it hard, but instead enjoy the temps. I very much like wandering downstairs to make a cuppa. Could be 3am, could be 7am, just nice

Yes, it is amazing the difference it makes. When I moved to our current property I used to get up to go to work at 4am gibbering away. Insulation, fireplace blocked up made the first difference. Now we have the HP on all the time and the car preheats . We also haven't filled the woodstore since installing the HP and I really have no idea when we will fill it again. It's now a backup for power cuts. It is quite amazing the changes to habits these things have. Next time I may go for a slightly smaller HP and run the fire though with the current price of night electricity its cheaper to run the HP.

I'm guessing that your stove hot pots have reduced in number quite a bit and you are back to the kitchen.

Nice one Andy, especially the gibbering, big fan of that! Stove still gets a run when cooking but maybe for 6 hours across the late morning into evening all very low key rather that the 16hr full bore frenzies of yesterWinters. Chilleeedddd.

Off to see Valley of the Kings so an early start. Last 24hr figures with DHW shifted to 10.30 today.

[Joeboy]

A couple of weeks have passed since the AAV was fitted to the system close to impeller. No data error problem since.

Here's the tale of the tape for the past fortnight.

Glad that the guys got it sorted out.
