Gas Geyser Installation
in Rustenburg

It varies widely with the unit and the work, going by what people report. On MyBroadband, one member paid R4,500 for a 16 litre unit installed and another about R12,000 for a 20 litre-a-minute fan-assisted unit (both in 2015). A 2023 post put the gas installer's pipes, fittings and CoC at about R5,000, with about R2,000 more for the plumbing. Your price is written down line by line, from the cylinder to the tap, before anything is bought.

It is issued by the installer who connects the gas, who must be registered with SAQCC Gas, according to the LPG Safety Association. In one 2023 MyBroadband post the certificate was part of a bill of about R5,000 for the gas pipes, fittings and CoC together. Ask for the CoC to be its own line on the quote, so you know what it costs.

It can be completed as soon as the installation has passed its tests, so agree before work starts that you receive it when the job is done. One MyBroadband member was still waiting after three weeks in 2022. Keep the final payment back until the certificate is in your hand and the owner's section has been explained.

Only if the room, the flue and the ventilation meet SANS 10087, which is strict about bathrooms. A gas water heater burns air and gives off exhaust gases, so the code controls where it may go and how it is flued and ventilated. An outside wall is the simplest place for one. If you want it indoors, the registered installer must show you that your room qualifies.

That depends on how many hot taps run at the same time, because gas geysers are sized by flow in litres a minute rather than by tank size. Units of 16, 18 and 20 litres a minute come up in MyBroadband posts by people who bought them. A unit that is too small gives hot water at one shower and lukewarm water at two. The installer works out the size from your shower heads and taps.

Because the flow has gone past what the burner can heat. Each unit can only warm so many litres a minute, so with two taps open both run lukewarm. Low water pressure causes a similar problem, because the unit needs enough flow to keep its burner lit. A bigger unit or better pressure solves it; see water pressure repairs.

Yes, if the gas unit's maker allows pre-heated water at its inlet. A unit not made for it can overheat water that the sun has already warmed, so a tempering valve on the outlet is fitted to keep tap temperatures safe. Ask for the model and its inlet limit to be named on the quote. For the solar side, see solar geyser installation.

You need both kinds of work. The water connections are plumbing, but the gas connection is made by the registered gas installer, who also issues the Certificate of Compliance. One person can hold both skills. Whoever connects the gas, ask to see their SAQCC Gas card.
