[permaculture-oceania] Electricity usage ofelectrichot waterheaters

[Anne Burns]

Steve,
We have a 200 litre off-peak system that was converted by the electrician to 
continuious heat with a button installed so when we arrive at the house we 
press the button, the system heats up to desired temp. then cuts out.  We 
can go for 2-3 days then we press the button again, to lift the temp.
We have been doing this for 4 years now with no apparent side effects to the 
heater.
cheers
anne
