Am I right in thinking the FF only has one compressor? If so, it probably uses a bit less than a separate fridge and freezer. With one integral fridge, one integral freezer, one free-standing larder fridge and one small free-standing chest freezer (in the garage) I would expect to use around double of what you do for refrigeration.
I’m still waiting for the Bright app to fully populate but here’s what I observed during a night of fitful sleep interspersed with sneaks downstairs combined with some early Bright data…
The free-standing fridge being off cut early hours consumption by about 20 watts per hour. That doesn’t seem outrageous to me.
The integrated freezer compressor always seemed to be running when I went to the kitchen. I switched it off at the thermostat and cut current usage by 50 watts. That seems reasonable for a compressor. I left it off for three hours so will see what Bright says later.
I googled freezer compressor frequency and many answers suggested they are running most of the time.
Just before 7am I switched off all refrigeration and consumption dropped to around 130 watts. It looks like all four appliances together account for about 80 watts of every hour’s usage.
I then switched off the external lights and consumption dropped to 110 watts. I made sure the boiler wasn’t firing and the pump in the airing cupboard was off. So where am I using this 110 watts every hour?
I switched off the power to easily accessible AV equipment in one room. This was power to a tv and a fire stick. I left the PVR on standby so it didn’t lose the recording schedule. That only shaved off 3 watts.
I have 107 watts still showing on the IHD. What’s using it?
There are three more televisions, one freesat box, one fire stick, one dvd player with power applied. It’s awkward to switch most of this stuff off and the freesat pvr would lose its recording schedule.
There’s the router, printer and PC speakers, oven clock, microwave clock, IHD and three phones on charge.
I’m not sure that little lot would use 107 watts so I might have some leakage somewhere. I could certainly shave a bit more off by killing some AV stuff but judging by the 3w the little telly and fire stick consumes, it might only be around 15-20watts.
That might leave around 90 watts unaccounted for. I’ve just switched off the cooker switch to isolate the oven. That only got rid of 1 watt.
I’ll do some more investigating at my leisure. 90 watts isn’t a whole lot but at 65p per day that’s about £20a month or £240 a year.
What have I started now? 😂
