Thats interesting about the Honeywell valves. Our flow rate is below what it should be due to them using 28mm plastic instead of 35mm copper so we’re ...

I took some measurements today. Clearly can see the rads and UFH aren’t losing 5c so makes sense why the main ASHP delta isn’t 5c I’m finding it...
Annoyingly I can’t view current day usage. But previous days have been 40-50kWh when it’s about 5c outside in the day. forcast -4c later this week ...
