The Dewhot Bucket Test : Determine your flow rate
16L Constant Temperature Gas Geyser FAQs
You can comfortably run multiple hot water outlets simultaneously with your 16L Constant Temperature Geyser, as long as the total water usage stays below 16 liters per minute. This makes it ideal for running two showers with flow rates of 8l per minute.
- 2 x showers
- 1 x showers + sink
- 1 x Bath
Remember: for optimal performance, ensure the total water flow from all outlets doesn’t exceed 16 liters per minute.
Do the bucket test to determine your flow rate demand and make an informed decision when choosing your geyser size.
The 16L rating indicates the geyser can collectively heat 16 liters of water per minute. You will never run out of hot water as long as you have gas.
The 16L capacity is ideal for smaller homes with 2 showers or one shower and a sink.
The cost of heating a litre of water is the same regardless of the size of the geyser. The maximum amount of water a 16L gas geyser can heat at any one time is 16 litres per minute.
The constant temperature gas geysers enables you to service taps from multiple sources at the same time. For example: If all your taps have a flow rate of 8 litres per minute each, and you run one outlet for 1 minute, you will only pay for 8 litres of heating. But if you are running 2 outlets at the same time for 1 minute, you will pay for 16 litres of heating.
