Is your geyser going to be installed indoors or outdoors?
What size geyser will you need based on your flow rate?

What is the difference?
Indoor and outdoor gas geysers are different models with distinct features for each application. Indoor gas geysers require a flue and are built with additional safety sensors to ensure safe indoor operation, while outdoor gas geysers require a protective weatherbox for outdoor longevity and safety.
Do you need a single use or mutiple use geyser?
Indoors
Type B
Single-use gas geysers are designed to provide hot water to a single outlet at a time. They are ideal for independent showers or basins and are not suitable to use with both a bath and a shower at the same time.
Outdoors
Type D
Multiple-use gas geysers can supply hot water to multiple outlets at the same time. They are well-suited for households with multiple bathrooms with baths, showers and basins.
Identify your flow rate to determine your geyser size
Gas geyser sizes depend on the flow rate per minute. Flow rate, or flow demand, is the total number of liters per minute that your taps or outlets use when they’re turned on. You can calculate your flow rate using the simple bucket test.
- Place a bucket under your largest cold water tap
- Turn to full and run for 30 seconds
- Turn to full and run for 30 seconds
- Measure how much water is in the bucket
- Multiply that measurement by 2 to find your flow rate in litres per minute
- For multiple use models repeat this process for each tap but make sure that all your taps are running at the same time
- Add all the flow rates together for your overall flow demand
