Heat Pump Installation Services – Smarter, Sustainable Hot Water
Power-Efficient Hot Water for Smarter, Sustainable Living in Johannesburg and Pretoria
South Africans are paying more for electricity than ever – and the environmental cost is rising too. At Alpha Plumbing, we install high-efficiency heat pump systems that use far less power than standard electric geysers, helping you reduce monthly bills and shrink your footprint without giving up reliable hot water. Sustainability isn’t a buzzword for us – it’s how we build.
We do the plumbing. You do uninterrupted life. That includes future-ready water heating systems designed for real South African homes.
Why Heat Pumps Make Sense in Gauteng
- A heat pump uses ambient air – not direct sunlight – to heat your water
- It uses up to 70% less energy than a conventional electric geyser
- It performs consistently and reliably at night, in winter and in shaded areas.
That’s what makes it ideal for Gauteng homes where solar isn’t always an option due to shade or roof limitations, and electricity costs that keep rising.
The Pay-Off: Savings, Reliability, Sustainability
Switching to a heat pump pays you back in more ways than one:
Lower monthly bills: up to 70% less water-heating electricity usage means saving money without sacrificing comfort
Year-round performance: works day or night, rain or shine – unlike solar, it never depends on the weather
Smaller carbon footprint: use less grid power and shrink your CO₂ emissions
Future-ready: integrates seamlessly with solar, timers, and water back-up systems so you can upgrade over time

Smarter in a System: Heat Pumps + Solar + Back-Up
A heat pump still uses electricity. It just uses much less per litre of hot water. If you want even more savings and resilience during outages, you can pair it with solar panels and a battery or generator to power the pump through load-shedding.
Pairing it can unlock more:
- Solar panels + battery: generate electricity during the day and keep the pump running even when Eskom is off
- Water back-up tanks: make sure you have water to heat when the municipal supply is off
- Smart timers/controls: shift heating to cheaper tariff times and align with solar power generation
How Much Can a Heat Pump Save You?
Every home is different, but here’s a simple guide to the kind of monthly savings you can expect when switching from a standard electric geyser to a quality heat pump:
| Household Size & Usage | Electric Geyser (Typical Monthly Cost) | Heat Pump (Typical Monthly Cost) | Estimated Savings |
| Family of 4 (ave. use) | ±R800 | ±R250 | ±R550 per month |
| Family of 6 (heavy use) | ±R1 100 | ±R400 | ±R700 per month |
Payback period: Most households recover the upfront cost in 2-3 years. After that, the savings keep coming.
Environmental bonus: Using less grid electricity means cutting your carbon footprint by 1.5-3 tons of CO₂ each year – about the same as planting 60-120 trees annually.
Note: figures are based on typical usage in Gauteng and may vary depending on household habits, electricity tariffs and hot water demand.
Heat Pump FAQs
Yes. Unlike solar geysers, heat pumps don’t rely on the sun – they extract heat from ambient air and perform well even in cold conditions.
It depends on your household size and hot water usage. We’ll help size it right – too small wastes power; too large wastes money.
Not directly, but solar panels can power your heat pump. We’ll advise if the solar + heat pump + battery combo makes sense for you.
Often yes, especially high-pressure cylinders with good insulation. If not, we’ll give you a quote to upgrade the geyser only, not your whole set-up.
Most modern units are very quiet and are comparable to a fridge or aircon outside. We install in the right location to reduce impact.
