ASHP & triple glazing

[Stinsy]

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.
