When it comes to buying a geyser, the size you choose can have a huge impact on your everyday life. If you get a solar geyser that’s too big, you’ll end up wasting a lot of power by heating up more water than you 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 imperative to carefully consider your geyser size prior to making your purchase.
If it’s your first geyser purchase and you are not familiar with water heating systems, then the variety of geyser sizes to choose from can be rather overwhelming. You must understand 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 different; therefore, it is important to understand that there is no ‘one-size-fits-all’ approach to buying geysers.
- Granny cottages
Granny cottages or staff units, with a kitchenette and shower, normally have basic hot water consumption needs and therefore don’t require a solar geyser with a large water storage capacity. A small geyser with the capacity to hold around 50 litres of water would suffice for this sort of living arrangement.
- A small apartment for two
A two-person apartment with a small shower and kitchen won’t use up much hot water unless you or your partner have a habit of taking long showers. But if you use water sparingly, then you shouldn’t need anything larger than a 100 litre geyser.
- A family of four
If your family doesn’t use more hot water than necessary, then 200 litres is perfect for four people. However, this solar geyser option can also work for a family of three with heavy hot water demands.
- A family of five
For this setup with average hot water consumption needs, it’s recommended that they install a 250 litre solar geyser.
