I don't know about Sweden, but the UK monarch is an aristocrat that owns loads of land, businesses, trusts, etc, and his money comes from that. At least, he gets to keep about a quarter of it; the rest goes to the Government.
Why not just use standard thermostat functionality: set the target temp a bit higher when rates are low and a bit lower when rates are high.
That was my original idea and it actually works pretty well, but since the cost of power spends most of the day at industry average rates electric heating gets pretty expensive which is really what I'm trying to minimise.
One thing you don’t mention is whether you have any way to store heat
I don't, but I really, really wish I did. The place I'm in is rented so I'm loathe to make big changes like installing storage heaters (installing relays in the walls behind the current radiators doesn't count, shush) but I had old-fashioned, 1980s storage heaters exactly as you described in my old place and I loved them for the exact reasons you described. They weren't active with a fan, but even just having a very heavy, very hot thing in the corner of the room was enough to maintain the temperature and given my electric rates regularly get below 5p/kWh and sometimes even go negative overnight my heating bill was basically negligible. Consider me a member of Team Storage Heaters.
As you suggested, what I'm trying to do is turn my walls, floors and furniture into the thermal mass of a storage heater, by making them toasty when it's cheap in the hope they'll keep the room slightly warmer when it's expensive.
Thanks, I already suspected I would need to get Excel involved and this confirm it! The window thing you mentioned is very real - my place has single-pane 2×3m windows everywhere; their insulative properties are basically negligible.
Once I've got a reasonable set of estimates going I'll probably push the calculations into a Helper to produce daily numbers automagically. If it works reasonably I'll post an update on here. Thanks again!
Thanks, I gave that a go and it actually came up pretty close to the numbers I already had (after converting BTU to kWh anyway) so that was a useful sanity check, thanks!
Three HP ProLiant servers running ProxMox cluster. Each box has a VM for Portaiber, as well as mismatch of VMs running Home Assistant OS, OpenWRT, Ubuntu, Windows and Debian, along with a Windows file server that connectes to four cheap NAS running Ubuntu LTS with a combined 20 mismatched hard drives by iSCSI and borgs them together with Storage Spaces.
So I'm not a programmer but I work with a few and they told me that due to the way that certain processor architectures store integers as floating-point numbers, this can happen when a track is listened to exactly 5,815 times.
Okay, so, yeah. "Righty tighty" never worked for me but you know what did? Turning Clockwise would eventually make the screwhead block up against the wood. "Clockwise, blockwise".
So I'm late to the party here, but this is a very early version of a diagram I'm putting together that corrects a couple of issues with the diagram OP posted.
As I said: very early and also very incomplete, but what's there is accurate.
The runners on my vacuum are fucked so not in my case, no.
