South Africans saving on electricity bills with IHP geysers

South African households can replace their electric geyser with one that has an integrated heat pump (IHP) and pay off the cost through electricity savings in less than 3 years.

Once paid off, the investment would cut down their energy bills by more than R11,000 per year based on current tariffs.

Typical for what? A guesthouse?

I don't even use that much in total with an electric geyser per day.

265 kWh last month means an average of 8,83 kWh per day for me with timings, so 10kWh doesn’t sound crazy if it’s just on 24/7.

But their IHP figures are also complete bogus and makes even less sense when the conventional is so high.

R30k is rough to spend on a hot water heater. I know it is a big chunk of the electricity bill, but if you have solar, I think you would be better off with just buying more battery capacity.

You can buy an extra 10kwh for that, and if you already have solar, the installation wouldn't be that much.

I am wondering if this 30k geyser will even last longer than the batteries.

The other thing is how easy it is to clean inside.
When they last long, there are a lot of bad things inside the geyser.
 
Even if you went the solar geyser controller route. It will set you back about 10k. If you do it with a professional install you will hit about 15 to 18k. The 1.8kWh the heatpump supposedly uses a day (more lie 3 to 4 from the other thread) can be used to top up the geyser in the mornings if needed.

So exactly the same electricity consumption as the heat pump at half the price. And you dont have to deal with maintenance or breakages.

I've been saying for years. HP only makes sense if you run out of roof space.

Ours averages at around 9kwh. Family of 4 and we try to use warm water sparingly. Not sure how that compares to other people.
