Testimonials

★★★★★
Reliable hot water, even in load shedding
We installed this in our Cape Town home and it heats water quickly whenever the power is on. It’s been a great addition to our home, especially with how unpredictable load shedding can be.

★★★★★
A great upgrade for our home
Our old geyser was unreliable, but this instant heater gives us hot water when we need it. It is compact, works well in our Durban home and has been a real win for the family.

★★★★★
Lower Energy Use
We’ve noticed a real difference since switching to ThermoTech. We only heat the water when we need it, instead of keeping a large tank hot all day. It’s been a much more convenient and energy conscious option for our home.
FAQs
How does it work during load shedding or a power outage?
An electric instant hot water heater needs electricity to heat water, so it will not actively heat during load shedding. However, it heats water only when you open the tap, meaning there is no tank constantly reheating and wasting power. When power returns, hot water is available again immediately — a smart, efficient upgrade for South African homes.
Will one unit be enough for my whole home?
For many homes, one correctly sized unit can supply hot water to the main bathroom, kitchen and other outlets without the standby losses of a traditional geyser. Your ideal unit depends on household size, water pressure and how many taps run at once, so choosing the right capacity is key. We can help you select the best fit with confidence.
How much could it save on my electricity bill?
Savings vary by household usage, tariff and the geyser you are replacing, but instant heating can reduce wasted energy because water is heated only when needed — not stored hot all day. That can mean lower electricity consumption and a more manageable monthly bill, especially for smaller households. Make the switch to a more efficient hot-water setup today.
Is it difficult to install?
Installation is straightforward for a qualified electrician or plumber, but the unit must be matched to your home’s electrical supply, water pressure and required flow rate. Professional installation helps ensure safe, reliable performance and the best possible efficiency. With the right setup, you can enjoy instant hot water without the hassle of replacing a bulky tank.
