MBC High Performance timber frame energy consumption in November

[RedRhino]

We are entering our first winter in our self-built timber frame house.
ChatGPT created a graphic and I thought people might like to see it. 
With MVHR the good and bad news is that room temperatures tend to equalise; and the rate of cooling is slow so nighttime temps are very similar to daytime temps.
On that basis we have just one thermostat on the ground floor which is set to 21c. 220m^2 across three floors. No heating upstairs. Tesla Powerwall 3 to store solar. We only exported about 10kwh in November.

Great post, thanks for sharing here. 
 

Can you use the ASHP to cool? Doing that for a few hours in the afternoon to early evening may help knock off 1° which would be quite significant for having cooler rooms when you are looking retire each evening.

Thanks for the comment.
I believe the current gov’t ASHP grant is only applicable to heating machines rather than heating / cooling machines. 
So no, ours doesn’t cool. Our bedroom only has easterly windows to avoid overheating in summer. 
As mentioned, we have no heating upstairs so the bedrooms are cooler: about 18c.
