ASHP & triple glazing

That's a fair bit of work to fill that cavity but you will get the benefit from it for years to come.

You need to get that air in the system sorted out, decide what mode to run the heat pump in, set a heat curve and see what it's like over a longer period. Probably start off with a higher heat curve (don't want Mrs I feeling the cold ) and take it from there.
Like I said mine is set at inactive, no night setback and the heat curve at 0.4 (was at 0.35 before the cold weather arrived).

Aye on the air. Still not sure it is though. I've dropped the dhw flow rate to 53% for tonight. I'll see what it does. Heat curve currently at 0.45. 0.6 is my freeze goto setting. If the air alarms continue I'll get them back out to bleed.

Have you checked your expansion vessel? If it isn;t pumped up correctly or isn't big enough then when the water in the system warms up it expands and a bit seeps out of the PRV, then when the system cools it sucks a bit of air in through the PRV.

Haven't checked that. Tbh, if it keeps throwing data errors I'll get the installers back. It's only the 3rd party monitoring not the HP itself.

The black cold patches are in full retreat.

Upcycled the front lounge skirting boards (ogee) via the part solar operated tablesaw to simple boards. All went in well along with some thin insulation sheet to match heights with existing floor.





Temperatures in that room are now absolutely excellent. Plastering tomorrow if floor cures ok overnight.

Managed a sub 30kWh day so far. Exporting at the moment too. It's January, right?

I like the idea that our 1.5kWh per day saved can be exported. Just another way to ensure that we work from as close to source in our RE as possible. Generated a couple of kWhs too off the PV.
