3 bed house, gas heating and water, probably half LED lighting, two people and our average is 275kWhHard to say I understand. But....3 bed house, gas heating and water. four people.
LED lighting throughout. No EV or large loads. 'Normal use' Average Electric use is 500kWh per month.
Would that seem a typical usage?
I'm sure an individual with your wherewithal could put a CT clamp on the relevant circuit?! Quite a few Raspberry Pi projects around the web will do multiple simultaneous clamps..very hard to measure how much used
Because the air being cooled by the window convects down, and the air being warmed by the rad convects up, the two meet at around windowsill area and mix, funnelling out into the room.So why do we fit radiators next to windows?
Unlike the kids, we'd quite like the heat to stay in for 40 years!would it not be better to heat centre of home, and let the heat move out?
Call the scrappie, buy one, get a reasonable amperage 12v power supply and wire it up. A friend has done just this after finding his Volvo seats to be the most comfortable he's ever sat it; 50 quid for a seat, mounted on an old office chair roller wheel set; heated, reclining, bargain. Tip, try and get a passenger seat - they're less often sat in and not quite so knackeredA heated chair seems a good idea, I have them in my car, why not in the house.
that might be the theory, ours was under the window, with the curtains closed the warmest prt of the room was behind the curtains next to the cold glass where heating loss is greatest.Because the air being cooled by the window convects down, and the air being warmed by the rad convects up, the two meet at around windowsill area and mix, funnelling out into the room.
If you put the rad on the opposite wall it warms and the air rises, the cooling air by the window falls, and you set up a convection cycle that encircles the whole room, making the occupants sit in a draught that makes them feel colder
and on top of that you would need to factor in the wste heat from the cooking that stayed within the house and supplemented your central heating, very important in the winter less so in the summer.I use a CT clamp on the oven circuit to measure the current used but it doesn't prove much. Different meals require different amounts of energy to cook and it also depends on the starting temperature of the food. You would need to cook exactly the same meal, starting with ingredients at exactly the same temperature by several different cooking methods to make the comparison valid.
I remember the days of the twin tub, and the piles of cloths on the kitchen floor, I am sure it was more environmental friendly, water being used many times, but the labour involved was huge, and we have to accept labour saving costs money.
If I look at my home, having a PIR to turn lights on in the hall and landing would clearly make sense, but only if wired that way from new, the cost to rewire would exceed any savings.
A heated chair seems a good idea, I have them in my car, why not in the house.
