- Any maintenance or alterations done to your gas installation requires issuing a new CoC for the ENTIRE system.
- An installation must be inspected, and a CoC issued when a property is sold.

Am I allowed to have a gas cylinder inside my house?
- If you live in a flat, you may have a maximum of 9kg gas either stored or permanently installed inside.
- If you live in either a free-standing house, cluster house or in-group housing (not exceeding two storeys), you are entitled to a maximum of 19kg. There are, however, strict regulations regarding the positioning of gas cylinders inside a flat or house and necessary ventilation.

Are gas geysers safe for home use?
Install in a well-ventilated area.
Ventilation is the most crucial safety measure when using a gas geyser at home. Our expert installers assess the most strategic and ventilated location to install your gas geysers, for example, mounted on a wall outside, on a balcony, rooftop, terrace, or other areas where maximum ventilation can be achieved.
Be on the Lookout for gas Leaks.
The second measure that ensures safety is to ALWAYS be on the lookout for gas leaks. Loosely fitted pipes or other utility fixtures become one of the most common causes of gas leaks at home. Be exceptionally vigilant when it comes to gas leaks!
Keep out of reach of children!
Like any potentially harmful device, KEEP OUT OF CHILDREN'S REACH! NEVER ask your child to turn on or off the gas geyser or let them fiddle its knobs. We always install your gas geyser in an area out of reach of children and recommend that you keep it locked. In instances where the home has limited placement, for example, in an apartment building, we install a safety grill around the geyser to ensure the safety of young children.
Keep a watchful eye on your thermostat.
The thermostat allows you to set your temperature at your desired levels. Avoid setting your temperature to 'very hot' for extended periods, as boiling water can accumulate extreme steam pressures. So, please re-set your thermostat to your 'normal' temperature after using boiling water. Fortunately for you, ALL our gas geysers are modern and have safety features that make them very safe. For example, if there is increased heat in the gas geyser, it has temperature sensors for the air temperature exiting the unit. If the temperature is too high, it will stop supplying gas to the burners. If that were to fail, there is a second water temperature sensor. If the outgoing water temperature is too high, it will stop supplying gas to the burner.
Servicing and Maintenance.
We keep track of our purchases to remind ALL our clients of the need for one of our installers to come and run a thorough service/maintenance on your gas geyser every 12 months. Your gas geyser needs to be maintained regularly like any mechanised item, including your car, washing machine, and stove. If your gas geyser hasn't been used for a while, please contact us, and one of our expert technicians will inspect it before turning it on.
Why are gas geysers great?
- Gas water geysers provide Just in Time heating! Use It Right Now! Hot water. They don't store the hot water to pre-heat. Instead, they instantaneously heat your water as it passes through the gas appliance.
- You aren't wasting energy by constantly heating the water. From a cost perspective, it will cost you less to run and operate a gas geyser than paying for electricity, based on the gas you use.
- You only need to set it to your desired temperature. For some arbitrary reason, Electric geysers in South Africa are typically set to 65 degrees Celsius. Anything higher than 50 degrees is likely to scorch you. That's why we usually mix in cold water to reach a tolerable temperature. How wasteful!

How do I figure out the best size for my home?
The Bucket Test
Now that you have determined your household needs. It is essential to calculate your highest flow rate amongst all your outlets. The bucket test is fool proof for figuring out what size geyser you need. This will give you an accurate gauge of how many litres flow through your most demanding tap in 1 minute and thus what size geyser you need to consider. We advise simply using your tub as a good gauge since it generally demands the highest water flow.
- Grab a 20-litre bucket
- Place it under all the taps you require running hot water (i.e., your shower, bath, kitchen and bathroom basin etc.). Open the tap and run water into the bucket for 60 seconds.
- After precisely 60 seconds, turn off the tap and measure how much water is in the bucket.
Making your final decision
Once you have determined each outlet's water demand, you can compare the demands and work out your highest usage. The size of your geyser is determined by the flow rate of the outlet that delivers the most water into the bucket. If you slow down your flow rate (for example, a smaller showerhead), you can reduce your flow rate demand.
Is one gas geyser enough for my entire house?
- It depends on the distance from the gas geyser to where you want to use it.
- One (1) gas geyser can supply two bathrooms if they are within 10 metres from the geyser.
- You should install another unit if the run is more than 5 metres from the geyser.
- If your bathrooms are within 5m of the gas geyser, but your kitchen is further, you can use one gas geyser for your bathroom and a smaller one for the kitchen.
How much does it cost?
Gas supply: Cages & Cylinders
- Prices on gas cages (single or double 19kg and 48kg) range from R1.8K (single 19kg cage) to R3.5K (double 48kg).
- Most gas suppliers want to exchange only, and without a cylinder, they can charge up to a R1k deposit per cylinder regardless of the size.
- For LPG prices (June 2022), the market is offering between R35 to R40 per kg.
Plumbing
Our plumbing jobs range between R2,5 – R4kk depending on requirements and mileage.Please do drop us an e-mail (info@hotwater24.com) or visit our website (www.hotwater24.com) for any questions or pricing issues.
Can I use a gas geyser off-the-grid?
- Our 12L and 16L gas geyser models are battery operated, meaning that the battery (Duracell D) ignites a small amount of gas with a continuous pulsating electric spark.
- Our 20L and 26L gas geyser models operate through a small backup power system like a UPS. A UPS compatible with the 20L and 26L gas geyser costs around R2,5k (excl. VAT).
Where is the best location for my gas cylinder and gas geyser?
Gas geyser location
Mount the gas geyser on a wall. In addition to being installed according to SANS, install the gas geyser close to where hot water will be used. Clearance must be allowed for servicing of the gas geyser. The gas geyser must be accessible without a ladder or scaffold. Make sure the entire front panel can be removed for service. You must be able to read the information on the rating plate.
