Water Boiler - On or Off?

[PVX]

Hi guys
Wonder if anyone can advice - I live in a complex and manually turn my hot water boiler on via the circuit board for 20 or 30 minutes daily. Some of the guys I work with say this is actually the inefficient way of getting hot water - can anyone shed some light? I would surely assume that leaving it on indefinitely would use more electricity?
Thanks in advance!

Its inefficient and bad for your geyser.... but there will be some debate about that here.

It uses the same amount of electricity to heat up the geyser as it does to maintain the heat over the entire day.
If you leave your geyser on then that load is spread out over the day to short bursts. If you turn it off then all of that load happens during the short period when its on.

Turning it on and off damages the thermostat and valves. When we had our geyser shut off remotely we had to change these every year (on a geyser less than 10 years old)
