Deciding between a 15 litre and a 25 litre geyser depends entirely on your household size and hot water needs. One is not inherently "better" than the other; the optimal choice is the one that matches the number of people who will be using the geyser.
According to the Voltas guide on choosing geyser capacity:
| Household Size | Recommended Capacity |
|---|---|
| 1 - 2 people | 5 litre water heater |
| 3 - 4 people | 10 litre or 15 litre water heater |
| Family of 5+ | 25 litre water heater |
Why Household Size Matters
Choosing the right capacity ensures you have enough hot water for everyone without excessive energy waste.
- 15 Litre Geyser: This capacity is generally recommended for families of 3 to 4 people. It provides sufficient hot water for typical daily needs like showers and washing dishes for this size group.
- 25 Litre Geyser: This larger capacity is suggested for larger families, specifically those with 5 or more members. A 25-litre geyser can supply a larger volume of hot water, accommodating higher demand from multiple users.
Selecting a geyser that is too small will mean running out of hot water quickly, while a geyser that is too large can lead to unnecessary energy consumption heating water that isn't used. Therefore, the "better" geyser is the one that aligns with the hot water demands of your household size, as outlined by the recommended capacities.
