    Default Two person household with off-peak electric hot water

    What is your hot water heating consumption?

    KWhrs and the number of days of the account would be great.

    2 x 58 year old married couple

    87 days
    country energy
    697.00 units@10 per kwh = 69.70
    service avail 87 days @8.299=7.22 ( just on the hot water component)
    Equals 76.92 +10% gst = 84.61
    about a dollar a day


    cold water washing machine
    a shower each per day
    no dishwasher

    Hope this helps

    Two person household
    92 days
    Ergon
    kWh 86 - $18.44 (minimum service charge, tarrif 33)

    Cold wash, with once a month hot wash (connect machine to hot water tap) to keep machine healthy. Water tank thermostat is set to 60c. This billing period was for warm weather period ended March. The current period has taken a decidedly cold turn and I expect the water heating bill to rise significantly.

    ... or maybe not. Admittedly consumption went well up for the 95 day period just ended - to 161kWh - but the overall charge for the tarrif is only $22.01.

    Hmmm...I thought we were thrifty with our hot water?

    You are paying nearly 3/4 less than us.

    Our tank is outside...wonder if that makes any difference?

    Make sure that the outlet pipe, the vent pipe and any exposed copper plugs on the tank are insulated. At least 3 feet of the outlet pipe, but ideally the whole thing. You'd be surprised at just how much heat those fittings leech out of the tank and the $ quickly add up.

    How you use the hot water makes a big difference too. The main use here is for showering. My family lived on tank water when I was young and I picked up the habbit of not leaving the water running in the shower. Get in, adjust temp, wet down, water off, soap up, water on, rinse off, water off.

    Just wait till that 9 year old hits her teens. Then you'll know all about big bills.

    I hear you! Three daughters with hair that Rapunzel would envy and a wife who has a sustantial mane. They can manage to run out a 400 litre tank! Thankfully it is dual element so it can reheat from the top element. I get scared when the bill arrives.

    Resurrecting an older thread...

    The house of Spanky is currently a batchelor pad (groovy baby) and I've been monitoring electricity use by noting the meter daily at 5:30am. So far weekday general draw (4 day average) is 3.25kWh, hot water is 1.1kWh. Hot water is probably assisted by the fact that the 'cold' water comes out of the tap at over 30c (currently 34c and its only 7am).

    Weekend usage should be interesting.
