There are already so many types of water heaters out there, and on top of that, this confusion about capacity, should you go for 10 L, 15 L, or 25 L? Whether it's a small family or a big one, this confusion is pretty common when buying a water heater. Anyway, we are here to help you figure out what exactly you need to focus on while choosing a geyser, so that your daily hot water needs are easily taken care of. What you need to do is think about a few simple but important factors, before you hit that buy button.
Key Things To Consider Before Choosing The Capacity Of A Water Heater
The first thing you should decide is how much usage you are expecting from your water heater. For example, are you planning to use hot water for washing dishes or doing laundry too? If yes, then we would suggest installing a separate water heater in the kitchen. It will make things easier for you, and also reduce the load on a single geyser.
And about the laundry, well, you are not washing clothes every day, right? So that's manageable. Now, let’s talk about what other things you need to keep in mind before making the final decision.
Secondly, how many people are going to use the geyser daily? For a couple or a family of two, a 10 L capacity might work fine for bathing using a bucket. But if you are more than three people or prefer bucket + mug or even short showers, a 15 L geyser makes more sense.
And for families of 4 to 6, or anyone using showers regularly, a 25 L model becomes almost necessary. Another point to note is your bathroom water pressure and whether you use a pressure pump, it affects the compatibility of some geysers.

Still unsure about the final choice? Let’s break it down simply, so you can pick the most suitable geyser capacity based on your actual usage. Here is a quick and practical summary to help:
10 Litre Geyser
- Best for: Small bathrooms, bachelors, or small families
- Energy Use: Lower energy consumption as heating time is short and water volume is less
15 Litre Geyser
- Best for: Small to medium families (2–3 members)
- Energy Use: Balanced consumption, heats faster than 25L and stores more than 10L
25 Litre Geyser
- Best for: Medium to large families (3–6 members) or shower users
- Energy Use: Higher consumption during heating, but better for multiple uses without reheating
Instant vs. Storage Water Heaters For Bathrooms
Now that you have got some clarity on capacity and have seen the top options, let’s clear the confusion between instant and storage geysers too. Both have their place, it just depends on your usage and setup.
1. Instant Water Heaters
- Instant geysers heat water as soon as you switch them on. They usually come in 1 to 10-litre capacities, ideal for hand wash, kitchen use, or quick bucket baths in small bathrooms. Since they don’t store hot water, they give unlimited hot water flow, but only in small quantities at a time. The heating is fast, but if too many people need water one after another, it can get slow.
2. Storage Water Heaters
- Storage geysers heat and store hot water in advance, which makes them ideal if your family has 2 or more members. Heating takes a few minutes, but once done, the water stays hot for a long time, especially in BEE 5-star models with good insulation. This type of water heaters are also suitable for high-rise buildings due to higher pressure tolerance.
