What Is Cascading?

Cascading is used to effectively run a household with its multiple requirements.

For example: Use a 6ℓ geyser to run a kitchen, a 10 – 16 for the shower and run both to the bath, giving 18 /min. Fit non-return valves so that the kitchen and shower can only run off their units.

SANS Compliance & Certificates of Compliance (COC)

In South Africa, all gas installations must comply with SANS 10087-1 and be carried out by a SAQCC-registered gas installer. An unregistered installation is illegal, dangerous and can void your household insurance. Every gas geyser installation we complete is issued with a Certificate of Compliance (COC), which you will need for insurance claims and when selling your property.

Areas We Serve

We install gas geysers throughout Cape Town and the Western Cape, including the Northern Suburbs (Bellville, Durbanville, Brackenfell, Kraaifontein, Kuils River, Parow, Goodwood), the Southern Suburbs, Table View and the West Coast, Somerset West, Stellenbosch and Paarl.

Frequently Asked Questions

How much does gas geyser installation cost in South Africa?
Installation typically costs between R5 000 and R15 000, depending on the geyser size, accessibility and pipework required. Including the geyser itself, a complete installation usually ranges from R6 600 to R29 000.
Can I install a gas geyser myself?
No. By law, gas installations must be done by a SAQCC-registered installer and certified with a COC. A DIY installation is illegal and will void your insurance.
How long does a gas geyser installation take?
Most residential installations are completed within a day, including pipework, mounting, testing and certification.
What size gas geyser do I need?
A 6–10 litre unit suits a 1–2 bedroom home with one bathroom; 10–12 litre suits 1–2 bathrooms; 16–26 litre suits larger homes with 2–3 bathrooms or commercial sites. We will assess your hot water demand and recommend the right size.
Does a gas geyser work during load shedding?
Yes. Gas geysers heat water on demand and do not rely on electricity, so you have hot water throughout power outages – one of the main reasons Capetonians switch.
