WATER – Dewhot have found that the biggest effect on their range of gas geysers and the way they operate is water, due to the following factors:
FLOW RATE – This is the biggest of the two and is why Dewhot have so many different sized units in the diaphragm activated range. The diaphragm activated range have an operating flow rate of their maximum down to half (which is true for all the sizes)
The flow rate in litres/minute is needed to size a geyser correctly so that the you the customer will get the hot water temperature and volume that you are expecting .
To determine the flow rate one must do a “Bucket Test”
BUCKET TEST – Use a bucket of known size and then run the COLD water tap of the shower, bath or basin (wherever the hot water will be needed), it must be the cold water as the hot water may be plumbed through an existing pressurised geyser and cold water is what will be connected to the future gas geyser. Run the cold water at the flow rate that you would normally use it at, catch the water in the bucket for a timed minute and then measure how may litres you have in the bucket.
This information gives you a flow rate of X litres/minute. You can now use this information to determine the size of the gas geyser needed for the outlet by selecting the next size geyser up from this figure and you will have the right geyser for your pipes, water pressure, personal preferences and shower head.

Please click on the link below to calculate the gas consumption of your selected gas geyser. By simply selecting your geyser size and intended usage time, you will be able see the running costs of your unit. Note: if you know the price/kg of LPG then you can adjust this, otherwise it will default to the average rate calculated.
PLEASE NOTE: This consumption tool is calculated on maximum consumption which is at a temp of around 65 degrees, to give you an indication, a shower is generally set at 40/41 degrees. The tool is a guideline and not an exact estimation, as there are variables.
We hope you find this useful and any constructive feedback on the use of this tool would be much appreciated.
