45k is installed for A 200L unit.. if the spec sheet is to be believed, you should be saving a considerable amount..
I am waiting for the opportunity to get mine installed, after I complete some other more pressing items..

The question should rather be how many years/decades of trouble free use do you need to make up the 20k difference in price to a normal geyser.

OK make that 40k difference in price

10 solar panels orientated correctly and a geyser timer will give you free hot water with a normal 3kw geyser.
R150K cab get you nice solar setup.

How do you get to 45k installed?
These things cost 25k, surely at most installation is another 5k?

For the specific one I am looking at, cheapest is 33k.. then there is my installation location, which requires a good bit of additional materials, as I am not installing in the same location as existing geyser etc..
My figure is a worst case scenario...
I found this:

Power-saving geyser with big financial benefits
South Africans looking to reduce their electricity consumption on water heating can buy a geyser with an Integrated Heat Pump (IHP) and start seeing a return on their investment quickly.

I think you guys are referring to this product. It was talked about on the radio today. It is a heat pump integrated with a geyser (tank), nothing more. During the interview the interviewer suggested something along the lines of, the efficiency of this product has not been discovered anywhere else in the world; I almost fell off my chair LOL

The product is being marketed as some ground breaking item. They are making direct comparisons to regular geysers and neglecting to compare it to a regular heat pump instead. It is misleading when they say the product is highly efficient by citing the fact that the unit uses 0.6kw of power in reference to the units power rating, and chose to conveniently not talk about the power consumption (kwh), which is a true measure. As an example, a 0.6kw heat pump will take approximately six times longer than a 3.6kw heat pump to heat the same amount of water, and will therefore use similar amounts of electricity to achieve the same outcome.
On the contrary, I actually find this product to be less desirable than a regular heat pump & geyser (acting as a storage tank that sits in ones roof); reason being this product cannot be installed inside your home which means the geyser component is exposed to the elements making it less efficient in winter months due to tank suffering greater thermal loss sitting outdoors. There is one benefit in that there will be reduced thermal loss when the water moves from the heat pump into the tank due to its integration, whereas in a regular heat pump & geyser combo, the water is pumped from the heat pump into the geyser in the roof hence some thermal loss, but the latter is still more desirable than the entire unit sitting outside. I use a 4.7kw heat pump and its efficiency drops significantly in the winter. I'm finding it hard to see how a 0.6kw heat pump is going to cope in winter with the tank having to have to stand outdoors.
I suggest anyone considering this option to carefully weigh it against a regular heat pump & geyser combo and don't fall for the marketing gimmickery.
