There are a number of different causes of high power use. Here's how to check your power usage and work out what may be causing it.
Firstly see which meter is high - is it the hot water (controlled) or household 24 hour supply - or is it both of them?
Check the number of days that the power use has been high, or if estimated then add the reading for a realistic usage over 2 months.
Compare usage with a similar time the previous year and make note of the difference.
Firstly check the Ajax valve and if there is overflowing at roof pipe vent for a low pressure system or for a mains pressure check the outlet pipe on the side of your house. Also ensure you fix any dripping taps. It's also good to check the temperature of the hot water and ensure the thermostat isn't set too high.
Inspect your hot water cylinder. If it is old there may be heat loss through poor insulation or pipe lagging.
Finally check your hot water usage to make sure you aren't running hot taps unnecessarily. Showers use less hot water than baths, and fitting an energy efficient showerhead can reduce hot water use.
If you have a spa or heated swimming pool, this can increase your power usage.
Take note of the household appliances you are running. Waterbeds, tropical fish tanks, water pressure pumps and aerated sewerage systems can all increase your power use. Are there any new appliances that may be having an impact? Or have you had visitors to stay lately?
The number and age of refrigerators and freezers could be causing your high power use. They need to be regularly defrosted and check the seals are in good condition.
Replacing standard lightbulbs with energy efficient ones will help to lower your power use.
Thermostats or timers on heaters will help control heat levels and power use.
It might also be worth working out if you can get a better power deal from another power company by checking out the What's My Number - whatsmynumber.org.nz and Powerswitch - powerswitch.org.nz websites.
