Instant vs Storage Geyser — Which Water Heater to Buy in 2025?
As winter approaches, the first water-heater question is usually: instant or storage geyser? Both heat water well — they just suit different needs. Here's a simple guide to choosing in 2025.
Instant Geyser
An instant (tankless) geyser heats water on demand, so there's no waiting and no standby heat loss. It's compact and ideal for kitchens, washbasins and single users. The trade-off: it heats a limited flow at a time, so it's not ideal for filling a bucket quickly or running a shower for a family.
Storage Geyser
A storage geyser keeps a tank of water hot and ready, making it the better choice for bathrooms and families. Sizes typically range from 6L to 25L+. It uses a little standby energy, but a higher star rating and good insulation keep that low.
How to Choose
By Use
Kitchen or single user: a 1–3L instant geyser. Family bathroom: a 10–15L storage geyser. High usage: 25L or more.
By Efficiency
A higher star rating cuts running costs over time. For hard water, choose a glass-lined or corrosion-resistant tank. More on this in our Geyser & Water Heater FAQ.
