New heat pump geyser, made in South Africa, promises 84% energy savings
South African homeowners struggling with high electricity bills may find a solution in the locally developed IHP Geyser. Utilizing heat pump technology, this innovative system aims to eliminate leaks and bursts while drastically reducing water heating costs compared to traditional electric geysers. Backed by Nedbank and Builders, it’s poised to be a game-changer.

Developed by Johannesburg-based Power4Less, the IHP Geyser features a 0.6kW “nano” heat pump, consuming an average of just 1.8kWh daily. Its IP68 waterproof design allows for flexible installation, and the company claims it’s leak-proof and burst-proof. An electronic anode extends its lifespan, and projected daily electricity costs are a mere R7.12. A smartphone app provides user control, and installation typically takes two hours. Financing options are available over 48 months.
In stark contrast, standard electric geysers (3kW or 4kW) can consume up to 24kWh daily, leading to significant costs and are prone to bursts, requiring annual anode replacements. Annual electricity bills can reach approximately R36,500.
The IHP Geyser efficiently transfers heat from the surrounding air to the water, allowing its 200-liter tank to reach 75°C using minimal power. Power4Less anticipates substantial long-term cost savings and a significant reduction in household carbon emissions. The geyser, manufactured in Japan and China with EU A+ energy efficiency certification, has an estimated lifespan of 10 years. The Institute of Plumbing of South Africa (IOPSA) is also training members for compliant installations.

The main drawback is the higher upfront cost: R24,500 at Builders (R30,000 installed) for the 200-liter model, or R35,000 for the 300-liter version (installed).
Nedbank is actively promoting the IHP Geyser via its Avo platform and will soon offer a maintenance-rental option with monthly fees roughly half the anticipated electricity savings. Avo renewables executive head Dean Harvey highlights the potential 84% energy saving, translating to potential electricity bill reductions of at least R1,300 per month. This South African innovation offers a compelling alternative for energy-conscious homeowners seeking long-term cost savings and a more sustainable water heating solution.
