I have been wondering about this for some time; am I a heavy consumer of electricity ‘in the background’? We may have rather more ‘drains on the main’ than some because we have a number of Amazon smart speakers, cordless telephones, many Zigbee and Alexa controlled lights and switches. etc. Not to mention a NAS, then there is a freezer and a fridge freezer, domestic devices that are never truly off - even if only to display a clock, then there is the network with a MESH system - the list seems endless!

What I am taking a long time to get to is with us drawing ~200-300 watts all round the clock is our background consumption of those little electrons abnormally high at approx. 7.2 kW/h per day? Some of it could be reduced a little I suppose but only inconveniencing ourselves and waiting for boot-up and resets when firing devices up to use them. (I don’t think designers and manufacturers do us any favours here as ‘standby’ to them is their idea of ‘off’.) I’ve also heard of smart devices to plug in in-line with fridges and freezers but how much they save, I have no idea.

So come on ‘Is my demand BIGGER than yours’? I suppose in the overall scheme of things, with a total annual consumption of ~10MWhs in an all-electric home, the 25% spent on convenience and ‘must haves’ is not the end of the world, after all, we want fresh food to eat whilst we listen to the radio, and that food has been cooked on the induction hob or the microwave oven, we like to see our way around the house and don’t much fancy using a bicycle dynamo to charge the iPhones, iPads and having 24/7 access to the internet and our friends (not to mention wasting everyone’s time on the renewableheatinghub!) Curiously, Toodles.

Our baseline consumption, the house running and doing its thing (WiFi, chargers, home sewage treatment plant pump (100w), fridges, security cameras, smart plugs, HomePods, all the other stuff I can’t think of that’s connect to WiFi, etc.), is between 600-800 watts, so ours is bigger than yours @toodles 🤣 😓

@editor >5.000 kWh’s per annum! Yikes, I thought ours was big enough! Amazed, Toodles.

@toodles

During a 24 hour period our baseload is in the 100W to 300W range with occasional dips below and surges above. Assuming a 200W / hr average would give 4.8kW per day.

We out this afternoon and drawing between 320 and 390W. Basically MVHR, dMEV fan in summer house, sewage plant fan, ASHP standby/pump consumption and general stuff. So about 8.5kWh without lifting a finger.

150W average overnight - in order that’ll be: fridgefreezer, mvhr, ftth router, water softener, loads of standby stuff. There’s no standby stuff that runs at >1W - I remember looking at a dab radio that was hot in standby at the shop, didn’t buy it. Telly usb power switches on/off other stuff - wii u, buttkicker (it does what it sounds like!) etc.

We’re at about 250-300W average overnight. Give that, on top of the fridge freezer, we’ve got a PoE switch, wireless access points, a CCTV camera, the Home Assistant server (on a PC), a DVR and a router all necessarily running, I’m not unhappy with that.

@majordennisbloodnok My base load is perhaps a little lower than that with, I imagine, similar ‘tech’, but no ASHP. 5.5kWh/day when we’re away. Something like 12-13kWh normal daily use this time of year. I’d originally thought that 13.5kWh of battery would be sufficient (assuming overnight ToU tariff) but now I’m not so sure - I’ll see how winter goes…

@ianmk13 Our average total daily consumption without the heat pump in use but including DHW needs is approximately 14-15 kWh - so that means our baseload is some 50% of the total (just to have some convenience here and there!)

I suppose we ought to increase our daily consumption somewhat, then our base load would not look so significant! 😉

Thoughtfully, Toodles.

@toodles I should probably clarify that, not having an ASHP, DHW is via a gas boiler.

@toodles discounting the ASHP and EV our baseline consumption (fridge freezer, lights, gadgets and cooking) averages about the same at 7Kwh / day, so mine is the same size as yours! 🤣 🤣

The fridge freezer is, as you would expect, the biggest consumer, especially during the summer
