Biggest Energy Guzzler

Postby Smurf1976 » Tue Jun 25, 2013 10:24 pm

Sitting here with my 13 KW, yes that's 13 KW not a typo, electric heating running I'm just wondering what your biggest household energy guzzler is?

I suspect mine might actually top the list unless anyone is smelting aluminium in the backyard. Thankfully I only use it when I can't be bothered lighting the wood fire and tonight was one of those nights - only got home at 8pm and will be in bed by 11. It does the job however - warms both the house and the electricity meter at the same time. :lol:

Good luck with that, mine is gas but still it has a decent fan to pump it all, and no wood fire in this house. :(

What is it..
A massive ducted RAC or resistive heating..

13kW... 50A... do the lights dim..?... :oops:

PS... just noticed another post by David, with a 14kW RAC...

Sorry, you have been trumped... ;)

Hi smurf,

Nice work! hehe! :lol: Good to keep those meters, transmission lines and transformers / sub stations warm, it's a community service after all. :lol:

Actually, the largest energy sink here is the microwave oven. It draws 80A to 90A at 24v. :shock:

Even the arc welder doesn't use anywhere near that many amps continuously (about 15A when continuously welding). :lol:

Mine is the RAC, 5-6kw input.

When you guys are talking about kw for RAC are you talking about the heating pumped in to the house, or the input energy required to pump it?

My 5-6kw input energy results in between 9 and 11kw of heating depending on ambient conditions.

My A/C is permanently wired to the grid, my solar system could not start it as it draws a peak of 140A (@240VAC) for a few milliseconds sometimes if the compressor is at top dead center when it stops.

My lights don't dim as the circuits on the house are fed from my renewable energy, but the ones in my neighbors house might ;)

Good question I had to put in a 40A CB for it, an inverter unit so no hard starts, used as little as possible, only really hot days the solar does not fully cover it when its running.

In my case that's a full 13 kW from the mains since it's resistive heating. So I think I've still got the "biggest guzzler" award so far at least. :D

A nice big 7kW heater in the lounge room plus another 6kW in total in the rest of the house (not including the bathroom). So 13 kW all up. On a positive side, it does warm the place up nicely and the cat likes sitting in front of the radiant heater in the lounge room. On the downside, well there's that 13kW from the grid.

In terms of connection, it's separately metered on Tariff 42 (which costs 16.757c / kWh). My overall bills are still pretty low, typically around $200, thanks to the 5.13kW of PV on the roof but if it wasn't for the heating then the power bills would be pretty much zero.

The other night I had the heating on, plus the oven, plus the George Foreman grill, plus some lights and the computer etc. And the heat pump HWS was running too. All up that's literally 20 kW !!!

As I said, I stick to the wood fire as the main means of heating. It's a lot cheaper than burning up 13 kW from the grid. Just turning on a couple of switches is a lot easier though.
