Episode 7 – Myth Buster: Geyer Size Guide: Is Bigger Always Better?
Geyser Size Guide: Myth busted – Bigger isn’t Always Better
In South Africa, one of the most common assumptions homeowners make is that a bigger geyser must be better. More litres, more hot water, more comfort - right? Episode 7 of the KwikTok series busts this myth wide open.
KK, our dependable plumber, explains why oversizing your geyser isn’t the solution. Chantelle, our sharp-tongued consumer champion, makes it memorable with her humour, reminding us that “big or small, wide or tall - quality is what matters.”

Why This Myth Exists
The myth comes from a simple logic: a larger geyser stores more water, so surely it provides a better hot water supply. While partly true, it misses two key issues:
1. Energy waste: Heating litres you don’t use drains your pocket.
2. Efficiency mismatch: A bigger geyser doesn’t mean smarter water heating.
In reality, choosing the wrong size can mean higher bills and poor performance.

Problems With Oversizing
● Higher electricity bills: keeping a large volume of water hot can add up quickly.
● Roof structure: Larger tanks can require additional roofing support.
● Slower heat-up times: Bigger tanks recover more slowly after heavy use.

Energy Efficiency Matters
Chantelle points out that “hot water doesn’t mean hot bills.” Oversizing your geyser forces your element to run longer, consuming more electricity than you need.
Smart alternatives include:
● Pair your geyser with a Kwikpump Heat Pump for cost savings.
● Installing a Kwiksol Solar Geyser to use the sun’s free energy.
● Wrapping your geyser in a geyser blanket to retain heat.

FAQs About Geyser Sizing
