High Electricty Usage. Is It Excessive?

My house daily electricty is around 40KWH per day = $10 per day.
Is it possible that neighbour is stealing electricity?
Fyi.
- I turn on split system 12 hrs per day during winter.
- Family of 4.

    turn on split system 12 hrs per day

    #endthread

    considering you havent said what size your split system is

    • +12

      Also depending on where you live (i.e. how cold it gets in winter in your house) and what temperature your thermostat is set to, that could easily explain it.

    • +7

      If OP is raising the temperature from 18C to 20C is going to be a lot less than 10C to 20C.

      All relative really, but OPs here likes to keep cards close to their chest.

      • +33

        OP worried ppl will steal his cards too

      • +14

        Actually cooling is less efficient per degree

        • +3

          Yeah. Heating is near perfect efficiency. The thing about efficiency is it can only lose that efficiency in things like movement, light and heat. Mostly heat. So if the goal is heat then it's real damn hard to be inefficient.

          • +17

            @DonWilson: Normal heating is 100% efficient. Air conditioners (heat pumps) are a lot better than that (up to 600%) because they are transferring heat rather than a straight conversion of electricity into heat.

            • +1

              @Lachy2437: This guy knows heat pumps.The down side is the more parts to the system (compressor, heat exchangers) and subject to ambient conditions for performance. I.e. if it's really cold outside, you're not going to be able to move much heat inside.

              • +6

                @magikz: For what it's worth, you need to hit around -15C outside for the efficiency to drop below 200%

                With Australian conditions you're unlikely to have many days below 0C where the COP is around 300%, and it's around 400% near 8C

            • @Lachy2437: My 3 story townhouse has 6 daikin split systems, 4 have died. They're about 15 years old. Gonna cost a fortune to replace them all.

        • Perhaps, but in my world (Victoria), the costs (and power usage) to warm up my house is significantly more than it is to cool down my house.

          • +1

            @JimB: That’s simply because it takes more energy to change a bigger difference in temperature. The efficiency difference won’t be significant.

            • +1

              @Euphemistic: In heating, house goes from say 14-15 deg in morning to 21 deg.

              In cooling, house in the afternoon goes from 27 to 21..

              So that's say a 6 deg increase/drop.

              I suppose, in heating, it's on for longer than cooling.

              Still not a fan of Reverse Cycle Heating, I feel cold at 21 deg compared to radiant heating at 19 deg.

              • @JimB: I find it highly unlikely your house is 14C on a cold Melbourne winter morning, seems like a lie.

                • +1

                  @plasmog: Only on the coldest of mornings will it drop below 15 from 19 the night before, so not often.

                  It’s a new house I built. I lived in cold houses before so I tried to avoid it as much as I can.

                  Airtight uPVC windows, double glazed low E glass, expanding foam between window reveals and timber studs, r2.7 in wall, r6 ceiling, etc etc.

                  Happy with the results but was hoping it wouldn’t drop below 16-17 overnight.

                • @plasmog: My house in Melbourne has been 12C this winter several days.

      • +1

        I'm fairly certain the price of your bill - if per/kwh remains the same and you use the unit for x hours per billing cycle - will go up per/°C for heating. I've tested this and lets say albeit this was 10 years ago my bill dropped significantly in price from using heating 30°C to something more reasonable between 21°C-24°C.. and yes the external outside temperature does play a role too with split systems. Inverters are fairly efficient these days but dialing up the heat in winter excessively will be responsible for costs. Wear suitable clothing in the house even with the aircon - cost savings arise! and at least you don't freeze-freeze to death either :)

        • 30c?

          Even 24c is too high.

          • +1

            @JimB: OP is a cold blood lizard that's why.

          • @JimB: Space! The last rental I was in was fuc-king huge - high ceilings, wide corridors, foyer was bigger than both my current bedrooms (zero-common sense in owners building the 4 townhouses) - the house was 275sqm+, 2-storey. Down-graded since then in both space and occupants living with. Was running the ducted refridge system upstairs on 30°C for a while until I got the bill: 600$+/2xmonths. We did have 2 other splits systems downstairs too. Was FT working so aircon only running few hours at night and than whole weekend - not whilst asleep.

            • @cobknob: Honestly if I was running RC heating on 30 upstairs + 2 splits downstairs, I would be surprised it’s only $10 a day lol

              As you said it takes a lot of energy to increase the temp by 15 to 20 degrees

            • @cobknob: Yep can agree with that. Open plan living with high ceilings and floor to ceiling windows all around seemed great at the time but trying to heat or cool the space now is an expensive exercise.

              Could probably stand to get thicker insulation, back when we built the standards were much lower. Double glazed/less windows would have helped.

          • @JimB: Link? / Deal

            • @1Kenobi: To what? Lol

              • @JimB: 24c or better rate

                • @1Kenobi: Lol look at what message I was replying too.

                  I was referring to 24 degrees C.

                  But since you asked, I pay 20.680 c/kWh with Tango in Melbourne. Flat rate.

                  • @JimB: Ah my mistake
                    Thought there was a bargain electricity rate to be had

                  • @JimB: Was tempted to see the price back in 2012. Probably 10c/kWh, but that could be generous. Can't even remem if there's consumption stepping - the more you use the more u pay per kWh, could be thinking of water. Anyway I checked my oldest e-statement

                    YEAR Price/kWh (~) Daily Supply Cost
                    2016 24c 45c
                    2022 27c 96c

                    That daily supply cost is over double. Crazy :p

                    • @cobknob: How the hell do you insert a table like the one you did?

                      Very unlikely it was 10c/kWh

                      Just checked my 2011 rates with Dodo and it was 16c/kWh. Daily supply was 55c.

                      Today, I pay 20.680 c/kWh and 66c a day for supply.

                      However it's not accurate to compare the two as in 2011 I lived in a different house with a different electricity distributor.

                      When I moved into my new house a few years back, I was pleasantly surprised that that the tariffs where noticeably cheaper with the even with the same retailer.

                        Only 1 energy retailer in WA like bamzero mentioned - Synergy mostly, and Western Power manages lines, etc and maybe some country. Multiple options for gas - AGL, Alinta, Kleenheat

                        • @cobknob: OIC.

                          For gas and electrical in Melbourne , depending on what area you're in, different distributors own the infrastructure.

                          Some charge (the retailers, thus customers) significantly more than others.

                    • @cobknob: I found some old WA bills going back to 2005. Prices are as of 1/7 for the year.
                      It was 2017 when they (almost) doubled the supply charge. I guess that's what happens when they encourage everyone to get solar, then realise everyone got solar.

                      Year Price KWh(~) Daily Supply Cost
                      2005 13.94c 25.6c
                      2012 24.88c 41.5c
                      2016 26.48c 48.5988c
                      2017 26.48c 94.9058c
                      2022 30.0605c 107.7685c

                      And there you go, todays price, and yes Synergy is the one electricity provider we have to choose from.

                      • @bamzero: I'm paying 27c per kWh with a daily supply cost at 96c still. Fingers crossed those 2022 rates you've stated ain't the new costs from July onwards - cause that just shitty

          • @JimB: Yes I have mine on 20c max.

      And if a/c is on all day, leaving doors and windows open only makes it work 10 times as harder !!!!

      The house may also have a big effect on how much it cost to run this heater.
      - Insulation in roof, floor, walls
      - Double glazed windows
      - External doors and windows are closed

      Missing any of those and you'll pay more on heating!

    • +1

      I went from 8kwh/day to 34kwh/day during winter when turning on my 14kW ducted system so you're not alone. Not sure if there's a flaw with my air con but it seems to run non-stop regardless of the temperature. The installer said that it's normal and that only the outside unit shuts off when the temperature is hit, the internal air keeps going non-stop.

      • Installer may be correct.

        I know for my ducted system, I have the option to let the system continue to run the fan once it hits set temp or to stop.

        Good for Summer as airflow makes you feel cooler.

        Bad for winter as unheated airflow makes you feel cold.

      • Is your outdoor unit shutting down?

        I have a 16kw system, and a large open living space. If I set temps to anything normally recommended it never hits it and runs continuously. It is pretty old so don't know if there's a problem (18 years or so it's at the age where prob not worth throwing $ at it but time to install a newer more efficient unit) but after experimenting with temp settings found the temps it can reach to cycle on and off which are enough to keep us comfortable (we don't mind a colder/warmer house than others it seems.)

        Keep adjusting the temp setting by a degree and wait a minute to see if the outdoor unit shuts down (or check power draw if you have a smart metre for solar etc).

        The other thing is how many zones you have on. They are usually designed to run 50% to 60% at a time so if you have more open it will struggle.

        As for the fans, that's right as is JimB. Usually they will continue to run though some systems have the option to stop them though it's not always user accessible, might need to get into service settings (my controller had a field setting to stop fans when heating temp was reached but unfortunately had no effect when I set it for my system)

    I'm sure running the split system 12 hours a day is unrelated and the most likely explanation is a neighbour stealing your power.
    They probably come around with a wheelbarrow when you are out and take 20 or 30kwh when you aren't looking.

    Without the sarcasm, I suspect you will find your usage will be much lower if you drop the thermostat a few degrees. The average house uses about 22kWh per day.

    • +4

      If OP wears a tin foil hat it will block the neighbours and stop them from stealing

      • That's not enough. You gotta enclose the whole house in a faraday cage.

    • (profanity) 22kWh, being single is cheap. I can hardly get over 1.5kWh a day

      • can hardly get over 1.5kWh a day

        1.5kWh/day?

      An oil heater is significantly less effectively than using a reverse cycle split system.

      • +4

        Depending on situation. The reverse cycle AC is more energy efficient, but if it’s in a big area that isn’t used much an smaller single room could be better heated using a different type of heater.

  • Using between $6-$8.50 per day here with a server on 24/7 (using 112w constantly), NVR on 24/7 (about 60w), 3 gaming desktops for about 4 hours, washing machine about once a day and gas heating so it doesn't contribute. Maybe 3-4 hours of TV.

  • +2

    Like OP blames stealing immediately.

    Our split aircon can consume on average 2kW if left on overnight, setting to 18C.

    • past few nights I have been kicking my feet and blankets off

      1-2 weeks ago my nose was cold and was burying my face. I would suggest getting a good down quilt and a thicker mattress protector with some insulation for winter. We havent even brought out warmest quilt out yet.

      One problem we have is I sleep hot and partner sleeps colder, so we have an extra blanket which I mostly kick off

      Even if you use 5x electric blankets you are still probably 1500w better off then using 2k kw overnight.

      One of the neigbours has their AC on 24/7, 356 days, even if its perfect weather outside.

      • Which is why i don’t have my aircon on at night.

        Unsure about OP

      • I doubt most people could stand to run their electric blankets on full power all night, so you'd probably be looking 50-70w per blanket at most. This would easily be the most economical heating option bar perhaps a new quilt.

        We've got heated throws for the couch as well and need aircon a lot less as a result.

      • "One of the neigbours has their AC on 24/7, 356 days, even if its perfect weather outside."

        Do they adjust their clothing to suit the opposite?

        One of my friends pretty much does this and wears short sleeve tees around the house in winter.

  • Ours is less than that with a pool. We rarely run AC.

    AC is what’s using all your power. Adjust the temp a bit (20-21 in winter, 25-25 in summer), run it less, a lot less.

    Check the copper wires on your consumer mains and fuse box
    If its severly corroded , it can be a cause of high power usage i was told

    • +1

      Whoever told you that is an idiot, and you blindly believing that makes you not the brightest bulb, copper corrosion does not cause increased power consumption, that would mean the resistance between your mains and your ac is increasing due to the corrosion, which is absolute bollocks.

      A quick google :

      Does copper corrosion affect conductivity?
      This reaction corrodes the metal which makes a film-like covering. Copper doesn't rust but it will produce a greenish patina called copper oxide. Unlike rust, however, this coating protects the metal from corroding without interfering with the conductivity
