Switching geyser off?
Posted: Mon May 25, 2009 8:45 pm
Some say switching your geyser off saves power, others say it depends how long you leave it off for, since when its turned on again, the element stays on a long time to reheat the entire geyser. What do you think?
It would great if someone could put together a formula for power consumed based on things like the specific capacity of water, element wattage, thermostat setting (target temperature), and temperature to which the geyser cools (ambient), which would allow some plots to be made of saving vs time a geyser is left off. Any offers? (It would need to be someone really sharp with their formulas, like Greystoke... )
