ASHP & triple glazing

[Joeboy]

Different sort of evening, not much wind & roasting! 19 degs outdoors.

Lower floor



Upper floor @ 21.35hrs


Upper floor was locked off at doors & windows. Interested to see what it drops to by 22.05hrs.



Edit-
22.05hrs, 2.5 deg drop in 30 mins. That'll do.



22.25hrs 20.5 degs

[Joeboy]

Overnight outdoors dipped to 11.7degs and rain overnight.

Upper floor 21.8 degs



Lower floor 20 degs



1 deg drop lower floor and 0.4 deg rise Upper floor . 0.063 deg drop per hour. Holy jamoley!!

That result is significantly better than I hoped for. I do have hopes for going forward May to September with ashp off for air heating. That might not seem much but up here it would be nothing short of a miracle (of insulation products).

The one thing I am going to have to give up is a Top SCOP figure. I won't have the balance of the daily air heating efficiency runs to compensate for the comparatively lower daily COP figures generated by water heating for the water nymph on her return to base.

Essentially we are out beyond what COP & SCOP signify (an efficient system). Since install we are seeing COP of about 6.0 to 6.5 for air heating and 2.4 to 2.85 for DHW

Here's where we are since system commissioned. By chance we are very close to the 6 month mark since commissioning so I can say 2.75MWh of power in half a year.
.
As I intend to keep the export going I should see the difference on a relatively even basis in count across the next 6 months for the 3G influence.



Looks like a dull day here today in reality and forecast. This will be a good example of what the home can now do in less than optimal conditions for retaining heat and generating power. I've switched off export for the moment and we'll just let it all run.
