Gas geyser prices in South Africa (2026)

What the geyser itself costs

These are prices for the unit only, as listed by South African sellers on 8 November 2026. They do not include fitting, pipes, cylinders or the Certificate of Conformity.

Sizes are flow rates, not tank sizes: a 16 L geyser heats about 16 litres of water a minute. The installer works out the size from how many hot taps you want to run together and your water pressure. Our gas geyser installation guide explains the sizes and positions in more detail.

What a fitted gas geyser costs

Installers in our network publish fitted prices that include the geyser, labour, the gas line (up to a set length), a pressure test and the CoC. Two things to compare carefully: whether the price includes VAT, and whether it is a swap (a new gas geyser in the place of an old one, the cheapest job) or a new installation (a first gas geyser, with new gas and water pipes). Gas bottles are usually extra.

Fitted prices from installers in our network

ShineBright Solutions: Fixed prices with materials, plumbing and installation, installed to SANS 10087. The 16 L price includes a weatherproof cover, a 5 m gas line and 10 m of plumbing; longer gas runs and plumbing are quoted separately. Source: ShineBright Solutions' own website (fixed gas prices, checked 8 November 2026).

Core Gas Installations: Includes the geyser, installation, travel, a pressure and leak test and the CoC. A new installation includes up to 10 m of gas pipe and 15 m of water pipe. Gas bottles are extra (9 kg from about R900, 19 kg from about R1,500, 48 kg from about R3,200). A swap replaces an existing gas geyser in the same place.

Each installer sets and quotes its own prices. Ask for a written quote for your home before work starts.

What an installation adds

The unit is usually less than half of the job. A quote for a fitted gas geyser normally covers:

• Labour to mount the geyser, connect the hot and cold water and fit isolating valves.
• The gas line: copper pipe from the cylinders to the geyser. The longer the run and the more walls it passes through, the more it costs.
• The gas supply: cylinders (bought or exchanged), a regulator, a changeover valve for two cylinders, and a lockable cage if you want one.
• Flue, cover or plug point, depending on the model: a flue for standard geysers, a weather cover for most outdoor units, a plug point for fan-forced models.
• Removing the old electric geyser, if you are converting.
• The Certificate of Conformity (CoC), which every fixed gas installation needs. Published CoC fees we checked in November 2026 run from about R600 to R1,500 for a compliant house. See gas CoC.

Why the price changes from one home to the next

• Type. Standard (manual) geysers are the cheapest units. Constant-temperature models cost more and hold the temperature steady. Fan-forced models cost the most but use gas more efficiently, can feed several taps and an upstairs bathroom, and do not need a conventional flue.
• Where it can go. A geyser close to the bathroom and the cylinders means short pipe runs. A geyser on the far side of the house, or on a double-storey wall, means more pipe and more labour.
• Water pressure. Low-pressure areas and tank-fed homes need a model made for low pressure.
• What is already there. Existing cylinders, a cage, a regulator or a gas line in good condition lower the price.

Cheap units and cheap installations

A low unit price is fine when the model carries the SABS mark and the installer is registered. What costs more in the end is a geyser fitted indoors without the flue or ventilation it needs, or a gas line put in by someone who cannot issue a CoC: insurers can refuse claims for gas work without a valid certificate, and a badly vented geyser can fill a room with carbon monoxide. Ask the installer for their SAQCC Gas registration number and check it on the SAQCC Gas register before work starts.
