Cost to run 2000W fan heater

Last year in December I had a hiccup on two red days and I’m too embarrassed to admit how much it cost me, a lot and it was pure waste. My only saving grace was that I wasn’t here for January and half of February by which time the bills had arrived and exposed my attempt to personally fund EDF S/E. So there were no other red day cock-ups that winter.

I decided I wanted a realtime consumption meter, not just a historic record. About ten years ago I had bought an Efergy realtime power usage device. Of course being young and naive (well naive anyway) and never having had a three phase house in my life (why would I?) I didn’t bother to check if we were one or three phase and it being a single phase device no matter how I fiddled it wouldn’t work, of course.

I didn’t know why it wouldn’t work so it was put away and filed under “long finger projects”.

Now having been through all the EV charger stuff and having a (currently (no pun intended)) pointless 22kW three phase charger I went looking for a realtime house use monitor. Efergy do one but it was difficult to hunt down, they seem intent on preventing not promoting sales.

Anyway, I installed it (easy as pie) and it’s been running for a few months now. I really like being able to glance at it see how much I’m burning through. I think similar devices are available on UK networks, ENIDIS should provide the option here.

I looks like the house just doing nothing (PCs, TV, chargers, routers, etc) uses 0.8 kW. Add in the pool pump and we move to 1.8kW. Oven, dishwasher, washing machine, dryer, chauffe eaus (though the new one of those is digitally connected🤔: ) etc.ect. all have their own footprint I’ve yet to map. One of the car chargers, runs at 11kW and I’ve the other trottled back to 7kW, which is fine for the R5. But the meter certainly lights up when both of them are plugged in.

All in all I like the realtime information and it’s certainly going to prevent me getting the red day shock I did last year.

So pool pump is 1kw, just to show off mine is 36 watts. We do not need to waste power on a pool and controlling this improves water quality and filtration effectiveness.

Indeed.

We’re still in the 300 heady days of blue Tempo @ 0.1494€ /kWh Heures Pleines & 0,1232€/kWh Heures Creuses (good news for some car charging tonight as I’ve got a longish round trip to do tomorrow & my solar hasn’t managed to get the car full today).

You are so right and I have noted your advice on this in the past. We only have a small pool and a .75hp was enough for us but when it blew up the only replacement they had was a 1hp one and I hadn’t read your advice at that stage or I would have gone for a variable speed.

However… my daughter’s pump in Oz blew up last week and during one of our chats I did say go for a variable speed pump (based on your advice). She told me today that they’d plumbed for a single speed at, I think A$500 because the variable equivalent t was A$1400. Even the guy installing the pump said they’s save a lot on electricity. A$ 900 is only €500 so i’d say the payback period was pretty short, I would have even paid the difference for them :slightly_smiling_face:

I should probably do the sums myself :slightly_smiling_face:

It’s possible to add a separate speed controller, a single-phase to single phase variable frequency drive.

Because my nose would resemble Rudolph’s.
