Buyer’s Guide – Point of Use (POU) Water Heaters
Have you ever stood at the sink waiting, and waiting… and waiting for hot water to arrive? Not only is it frustrating, but it also wastes electricity and water. Every litre that drains out while you wait costs money.
In Episode 3 of the KwikTok series, KK (our fix-it-all plumber and sparky) shows why Point of Use (POU) water heaters are the solution. Chantelle adds her trademark humour, reminding us that no one wants to “stand around like a backup dancer for Eskom.” Together, they prove that instant hot water is about more than comfort - it’s about everyday reliability.

What Is a POU Water Heater?
A Point of Use geyser is a small, compact electric unit installed directly at the sink - either undercounter or overcounter - to deliver hot water instantly. Instead of waiting for water to travel long distances through pipes from a main geyser, you get it immediately where you need it.
Kwikot’s answer is the Prisma Point of Use Heaters - compact, reliable units specifically designed for South African homes, offices, and commercial spaces.

The Problem with Traditional Hot Water Systems
Most South African households have a central geyser, usually a Kwikot Superline, mounted in the roof. While perfect for bathrooms, these systems are inefficient for sinks that are far from the geyser.
This “dead leg” - the section of pipe between the geyser and the tap, means:
● Cold water wastage every time you open the tap.
● Delays before hot water arrives.
● Increased electricity use as the geyser heats water that cools in the pipes.
KK explains that dead legs can waste hundreds of litres of water per month. That’s money down the drain.

Overcounter vs Undercounter Models
Kwikot offers two options in the Prisma POU range:
Overcounter:
○ The unit is installed above the basin.
○ Water flows directly down into the tap.
○ Often chosen for medical practices or older buildings.
Undercounter:
○ Installed below the sink.
○ Feeds hot water upwards into the tap.
○ Perfect for modern kitchens and sculleries.
The choice depends on your plumbing layout, available space, and aesthetic preference.

KK & Chantelle’s Take
KK gets technical, explaining how eliminating the “dead leg” makes hot water delivery efficient. Chantelle adds: “In plumbing, longer legs don’t mean hotter.” The humour keeps it light, but the message is clear: shorter pipes equal smarter energy use.
Energy Savings and Environmental Impact
In South Africa, water heating accounts for around 40% of household energy use. By using POUs strategically:
● Households cut waste from long pipe runs.
● Businesses save on operating costs.
● Less electricity is used overall, reducing strain on Eskom and the environment.
