Hey Lighty,
a couple of suggestions
a) for ± R 600 buy and install a timer switch for you geyser. We have found that it takes no more than 3 hours to heat up a 150l geyser. Work out a system where you all use the hot water at the same time. It saved us about R 300~400 per month.
Inquired today about a timer, about R250-R300 just for the unit
b) buy a thermal blanket for your geyser.
will do
c) change all your light bulbs for the high efficiency ones.
90% done, but the metal halides sre thirsty
d) your pool pump motor is more like 1kW, try shortening the cycle.
Mine is a BADU® Porpoise 10, only 0.67kw
e) install a gas cooker.
Though about this, but could be dangerous with my other half
f) fit "Think Pink" insulation in your roof for keeping the heat in in winter.
Ok
g) see if cold water washing is acceptable to your wife
h) switch lights off and learn to have only the lights on that are necessary.
i) don't fill your kettle boil only what you need / get a small kettle
Good point!
Cheers
Andrew
