When it comes to buying a solar geyser, the size you choose can have a big impact on your day-to-day life.
If you buy a solar geyser that’s too big, you’ll end up wasting electricity by heating up more water than you actually use. And if you buy a solar geyser that isn’t big enough, you’ll constantly run out of hot water. That’s why it’s important to carefully consider your geyser size before you make your purchase.
But if you’ve never bought a solar geyser before and don’t know the first thing about water heating systems, then the variety of solar geyser sizes to choose from can be rather overwhelming
Take note that the size of your solar geyser is largely dependent on your household’s hot water consumption needs. Every person’s water consumption needs are unique, therefore it is important to understand that there is no ‘one-size-fits-all’ approach to buying solar geysers.
1. Granny cottages
Granny cottages or staff units, with a kitchenette and shower, usually have basic hot water consumption needs and therefore don’t require a solar geyser with a large water storage capacity.
A small, compact solar geyser with the capacity to hold around 50 litres of water would be the best option for this sort of living arrangement.
2. A small flat for two
A two person flat with a small shower and kitchen won’t use up much hot water unless you or your partner have a bad habit of taking really long showers. But if you use water sparingly, then you shouldn’t need anything bigger than a 100 litre solar geyser.
3. A family of three
A solar geyser with the capacity to store 150 litres of water should be sufficient for a family of three, with average hot water consumption needs.
4. A family of four
If your family doesn’t use more hot water than necessary, then 200 litres is ideal for four people.
However, this solar geyser size can also work for a family of three with heavy hot water demands.
5. A family of five
For a family of five with average hot water consumption needs, it’s recommend that they install a 250 litre solar geyser.
