After the 12th November, we began using our pool heater. It is an inverter heat pump system, installed by Greenair and uses very little electricity. Each hour it is on raises the temperature by about 1c. With our solar panels, we are using the surplus units of electricity which we have produced over the year to heat our pool. I have estimated that we can use 27kw per day of surplus energy until March, when EAC takes away our surplus units.
On a cold night, our pool loses around 3c,(last night only 1c) but without a cover the loss would be much more. Today the pool was 20c when I put the heater on at 9:30am. By 2:00pm it was nearly 25c so perfectly swimmable. We used 9kw from our reserve of electricity and 29 units in total during the 24hour period which included air con heating, cooking etc as well as the pool.

Our system uses a lot less than 5kw per hour. Consumption varies according to the air temperature. With a 16kw per hour burn our excess units would soon disappear. If we were paying the standard grid rate, it would be too expensive to run.

Thanks for that John I’ve often wondered how much energy these system use and what the gains are. Don’t forget though that EAC have have now changed the billing systems for us net metering users so that target being ‘free’ when in credit, we effectively receive a discount in the units we use when we are drawing in more power than the panels are producing. Still much, much cheaper of course.
