    Unhappy PSE&G usage doubled the last two months

    Hello,

    I came across this forum in a Google search for an explanation of how my PSE&G electric
    bill has sky rocketed. I'll start with September of 2011 vs 2012 thru January of 2012 vs 2013.
    The household changes for 2012 are, my in-laws stayed with us from September 26th through
    January 7th 2013 & my son was born October 25th of 2012. The storm known as Sandy struck
    October 29th knocking out power until November 7th. The only changes to consumption aside
    from two extra bodies are the 2x wipe warmers, 1x bottle warmer, 1x baby swing and 1x baby
    monitor. The two wipe warmers are rated at 12v @850mAh, the swing is 12v @9 watts and the
    bottle warmer is 12v @ 350watts.

    The wipe warmers are on 24/7 while the bottle warmer is used as needed, roughly every 3 hours
    for 6 minutes. The swing is on an avg of 15 hours a day, it has music he likes to sleep to.

    I have read that a short in the ground cable or other PSE&G cable could be causing this increase
    but could I prove it? and wouldn't that short have to be on my side of the meter? The meter is
    attached to the house so this seems unlikely. I do have a second fridge that for about 7 months
    has been leaking water inside the unit rather than out to the pan. The temperature settings for
    this refrigerator are kept on the middle setting. It is a second fridge so it is in the garage, an area
    normally cold in the winter, if that could be impacting it's run time.

    What baffles me is that December, when the in-laws were here, is lower than January and my wife's mom
    cooked all the time and of course, more demand on the water heater. Now that they have left, we
    have not had time to cook so it has been take out from Boston Market or Cheesecake Factory every
    night in January yet the bill climbed. How can this be? How bad would the garaged refrigerator have
    to be running to suck up over 767kW? Mind you, I lowered the damn thermostat!

    When I call PSE&G, what should I tell/ask them to probe for areas that could implicate their equipment
    as the fault, if it truly is their equipment. If it isn't, my next guess would be the heat pump but that
    was installed in 2010 by the Home Depot and is a SEER 14 unit that has been running fine. What could
    I ask/tell the contractor that installed it to determine if the auxiliary heat strips are faulty? or coming
    on more frequently than really needed.

    Any help will be greatly appreciated as a $585 electric bill in December and a $718 bill in January has
    me very alarmed for the February bill. This is a 25 year old 1400sq foot townhouse with only 2 walls that
    face the outside, it's not a 3000sq foot 80 year old house with drafty windows!



    This is an average of PSE&G rates; $0.116845 per kWh.

    A frig that is draining may mean several things: the door seals could be leaking, or, possibly, the defrost cycle is stuck on. Older frigs are often MUCH more energy hogs than the newer ones.

    Do you have an electric water heater? Have you checked your water usage? You might have a leak and you're dumping a small, but constant amount of heated water possibly into the ground? Any spots around the foudation that seem wet(ter) than normal?

    It's unlikely that the meter is defective, but it does happen.

    There are some plug in devices, sort of like an extension cord, that you can use that will tell you how much power whatever is plugged into them is using. One I'm familiar with is Kill A Watt Electricity Usage Monitor. If you do a Google search on that, you can find various versions.

    What kind of heating system do you have? If it's a heat pump, and that's not working properly, it may be switching to the emergency resistance strip heaters (i.e., electric heaters), and that will be MUCH less efficient than a properly working heat pump.

    Do you get domestic water from a well? Maybe you have a leak and the pump is running much longer than usual.

    Hi Guys,

    Thanks for the replies.

    Just now I checked how fast that disc in my meter rotates around using the black line as a baseline.
    With lights and everything else plugged in with the exception of the two refrigerators, it took 54 seconds
    for the disc to rotate. The HVAC and water heater were also breaker'd off.

    With only the HVAC turned back on (and running) the disc rotates around in 2.3 seconds. Is that normal?
    Does it indicate the use of strip heaters?

    I do not have well water....so no pump. My water heater is in the basement and there are no leaks. The
    only water leak to occur January 6th was in the main line coming into the house but that was outside and
    before the water meter.

    You still haven't said what kind of HVAC system you have. On some thermostats, you can enable or disable the 'emergency' strip heaters. The only HVAC systems that have strip heaters are heat pumps or an all-electric heating system. It's obvious that your heating system is drawing a lot of power when on...now the question is why and if that's normal. Many heat pump system only need the resistance heaters when it is quite cold out, OR you've used a setback, and the amount of temp rise needed is excessive. If the heat pump is not working well, it may need the resistance, backup heat strips all the time, and this could easily add a lot to the electricity bill.

    My apologies, I overlooked that...

    Yes, it is a heat pump. A Trane 14 SEER system installed in 2010. I measured the discharge air
    from the vents and after the HVAC cycled three times, the average reading 95 degrees Fahrenheit.

    My thermostat is a White Rogers and I do not see an option in the menu to disable the strip heat.
