💡 A 25 L storage geyser covers 4 people with buckets back to back. Pick 5-star: standing losses run all day, and that is where the rating matters.
Instant geysers (3-6 L) suit kitchens and single quick showers only. Hard-water areas: look for glass-lined or blue-diamond tanks.
Frequently asked questions
Storage or instant geyser?
Instant (3-6 L) suits kitchens and one quick shower. For family bathing, storage (15-25 L) is more practical and gentler on wiring.
Why does star rating matter for geysers?
Storage geysers lose heat all day (standing loss). A 5-star tank saves real money if the geyser stays on for hours.
