I'm looking at getting hotwater insulation for my cylinder to help reduce electricity costs. I'm looking for opinions in regard to; are there any particular brands i should look for?, and how much money in electricity costs will i be saving. Also my hotwater cylinder is in the attick, could anyone please tell me if that would have any negative impact on my electricity bill? Some people switch off their hotwater between 7am and 11pm, i'm not quite sure if this would be a good idea or not?

My electricity consumption reduced considerably after I installed water saver nozzles in the showers and turned down the thermostat on the hot water service. 

I'm not sure that turning your HWS off for a period each day would help that much as once switched back on, the HWS needs to bring the water up to temperature.

I do however switch it off when ever I'm going away for a few days.

A wrap can be advantageous as hot water is extremely expensive to run but don't go silly if you have a newish cylinder or don't run it overly hot.

Most power companies seem to have put the line charges up the most astronomically in recent years which of course makes the bil a lot higher regardless of usage. If you work out pricing plans, most households usage is right between the "low user" and "high user" price points, that is not an oversight, it means you are getting the poorest value regardless.


Best way to save it to use hot water as little as possible,  unning the tap furtherest away from the cylinder less often works wonders for saving power.
