Is a heat pump a solar hot water system?
I have heard some salespeople vigorously defend the heat pump as a solar hot water system. It does use the heat (or warmth) of the air to heat water. The source of that heat is the sun. Therefore it can be seen as a solar hot water system.
But there are no collectors involved and it does need electricity to function. Far less than any electric hot water system though. That is the reason that it receives a Federal Government rebate and renewable energy certificates (RECs).
Heat pump advantages
The biggest advantage: no direct sunlight is necessary. We also recommend a heat pump where a solar hot water system is not feasible (e.g. for properties with an asbestos roof, when the north facing roof space is too far from where the water is to be used and of course where there is a lack of sunshine).
Heat pump disadvantages
The disadvantage: while producing hot water, it makes a noise (similar to an air conditioning unit). It is therefore best to put it away from any living areas. Electricity is necessary to power the fan that draws in air. This is minimal compared to an electric hot water system.

Hi, I currently have a medium sized conventual hot water system. could you please give me an indicative purchase cost of converting to a heat pump system. I am in Brisbane, Queensland.
Thanks for the help.

Hi Mark,
currently you’d be looking at $1,700 – $1,850, if you are eligible for all rebates (Federal Solar Hot Water rebate and Brisbane City Council rebate).
So even though that is more expensive than going for an electric system, it should cut your electricity costs for solar hot water by 50-70%. On top of that you reduce the greenhouse gas emissions by two thirds.
Please go through the free quoting process on this website for an exact quote for your situation.
It takes the details of your home into account and works out all rebate details.
