They were one glazing unit short on the van to complete both dormers so I get to see the method of how the trap windows will look while we wait for the glazing to arrive. Its ok, wind and water tight looks like. A bit non transparent though.
Once that dormer glazing unit is in, and cills, and final foam, AND finishing strips that completes the upstairs Southfacing. They'll then be starting in the big lounge South facing.
We only have one thermostat remaining in the house, on our bedroom rad. Turned it down last night to under 1.5. Only just got away with that (18 degs this morn in bedroom), will try it at 1 tonight. ASHP rad side now shutdown for 10hrs at start temp of 17.7degs.
Makes me wonder as to what Stinsy said. Will we actually get to a stage where body and transformer heat will have a tangible impact? My secret hope is to see a normal running 7kWh ASHP day, not bothered about the cop but just to see that little being needed will be great. An April cold snap test would be excellent.
That would be a 0.0035 value per sqmtr across the 200sqmtrs incl HW.
Costing at overnight price 49p
Or at half/half price allowing for solar generation for 12hrs 24.5p
The reality is of course negative costing and by a huge margin which i still can't really get me head to see as real. Writing it down here helps to get my brain across the line but i'll likely backslide!
Enerphit (I promised myself I wouldn't go here) heating standard is 25kWh per Sq mtr across the year. That's a figure of 0.068 or 5MWh PA in our house.
I should be able to get down to a self invented qualification to myself of 5MWh PA actual cost but no chance of getting down to a space heating value of 5MWh PA. I'll be interested to see what the 1 year non chaotic figure is on the home? 2025-2026.
