Heat Pump Installation in Cape Town
Lower running costs than a standard electric geyser, without a roof full of solar panels
T‑Rex Plumbing has installed heat pumps across Cape Town since 2011, based in the Southern Suburbs, with confirmed recent work in Claremont.
Is a Heat Pump Right for Your Home?
A heat pump costs more upfront than a standard electric geyser, but uses a fraction of the electricity to heat the same amount of water - it extracts heat from the surrounding air instead of generating it directly.
It's a considered purchase, decided on running-cost payback against electric or solar, not an emergency swap. We'll give you a straight answer on whether it makes sense for your household, not a sales pitch.

Heat Pump vs. Solar Geyser vs. Electric Geyser
Cost, lifespan, and running cost all factor into the right choice.
Electric
Lowest upfront cost, the standard option, but the highest running cost of the three.
Solar
New builds and full renovations must heat at least 50% of their hot water by an alternative to a standard element. Higher upfront cost than a heat pump.
Heat Pump
Our recommendation for most houses: cheaper than solar, low running cost, and the element stays as a backup.
Gas
Works without electricity, so it suits homes with unreliable power. The gas can run out, though.

What It Costs, and the Payback Period
A heat pump costs more to install than a standard electric geyser, but the running-cost saving pays that difference back over time - how long depends on your household's hot water usage.
We quote each installation individually because the right system depends on your home. As a guide, a heat pump typically pays for itself in about 4 to 5 years, and if it ever has a problem, you can switch the geyser's element back on so you're never without hot water.

Leon E AdendorffGoogle reviewGeyser repair
Excellent service! My geyser was pulling around 24 units of electricity a day and he came out and diagnosed and fixed the issue. He spent over two hours here making sure everything was sorted. Very professional, knowledgeable, and genuinely lovely to deal with. I really appreciated the time and care he took to get everything right. Highly recommend!!
Phumla NinelaGoogle reviewToilet and water pressure
Trevor and his team helped us on short notice with a toilet issue as well as a water pressure/temperature issue in our house. Trevor’s communication/admin before, during and after the job was a stand out. He also explained each issue and how it could be fixed in detail, which we valued.
