Gas Geysers in Randburg: What You Need to Know

Gas geysers are becoming the go-to choice for Randburg homeowners, and for good reason. They heat water instantly. No tank sitting in your ceiling, no element drawing power all day. You open the hot tap, the burner fires, and you get hot water. Close the tap, it stops. Simple.

We've installed gas geysers across Fairland, Northcliff, Linden, and Parkhurst for years. From compact units in townhouse complexes to high-output systems in large family homes, we size and position every installation for your property's specific layout and hot water demand.

Electric-to-Gas Conversions

Switching from electric to gas is one of the most common jobs we do. A Fairland homeowner called us after their ceiling-mounted electric geyser burst for the second time in three years. They were tired of the mess, the insurance claims, and the electricity cost. We removed the old unit, installed a wall-mounted gas geyser outside, ran a new gas line from the existing manifold, and connected it to the house's hot water pipework. The whole job was done in a day.

What's involved in a conversion:

  • Remove the old electric geyser and disconnect it from the DB board
  • Install the gas unit in a ventilated outdoor location (SANS 10087 requirement)
  • Run copper gas piping from your gas supply to the geyser
  • Connect to existing hot water pipes, no need to re-plumb the house
  • Test gas pressure, flow rate, and flue before sign-off
  • Issue a Certificate of Compliance on the spot

If you don't have a gas supply yet, we can install a manifold for standard gas bottles or connect to bulk LPG tanks. We handle the full scope, so you don't need a separate gas installer.

Gas Geyser Repairs

Gas geysers are reliable, but they do need attention. The most common issues we see in Randburg homes:

  • Pilot light won't stay lit: usually a faulty thermocouple or blocked pilot jet
  • No hot water at all: could be a gas supply issue, diaphragm failure, or ignition problem
  • Water not hot enough: flow rate too high for the unit's capacity, or the gas pressure is low
  • Strange smells: never ignore this. Turn off the gas and call us immediately
  • Rumbling or banging sounds: mineral build-up on the heat exchanger, needs a flush and clean

A Northcliff client had a gas geyser that worked fine in summer but couldn't keep up in winter. The problem? The unit was undersized for their household. It could handle one tap at a time but not a shower and kitchen sink simultaneously. We replaced it with a higher-output unit and the problem was solved. Sizing matters, and we get it right from the start.

Gas CoC Certification

Every gas installation in South Africa requires a Certificate of Compliance (CoC). This isn't optional. It's the law under SANS 10087. You need a valid gas CoC when selling your property, and your home insurance may refuse gas-related claims without one.

We issue gas CoCs on every installation we complete. If you have an existing gas system installed by someone else and need a compliance check, we can inspect it, identify any issues, and either certify it or bring it up to standard.

Annual Gas Geyser Servicing

A gas geyser that's never serviced loses efficiency over time. Carbon builds up on the burner, the heat exchanger scales up, and the thermocouple weakens. Annual servicing keeps it running safely and efficiently.

Our gas geyser service includes:

  • Burner strip-down and cleaning
  • Heat exchanger descaling
  • Thermocouple testing
  • Gas pressure check
  • Flue inspection
  • Full safety check

Serving Randburg, Fairland, and Surrounding Suburbs

We work across the greater Randburg area. Gas installations in Fairland's older homes often need careful routing around existing structures. Northcliff properties with their elevated positions sometimes need longer gas runs. Linden townhouse complexes have their own body corporate requirements. We know the local landscape and work within it.

We also serve:

  • Parkhurst
  • Greenside
  • Blairgowrie
  • Bordeaux
  • Ferndale
  • Randpark Ridge

Frequently Asked Questions

Is a gas geyser cheaper to run than an electric geyser?

Yes, significantly. Gas geysers heat water on demand: they only use gas when you open a hot tap. Electric geysers keep a full tank of water hot around the clock, which uses energy even when you're asleep or away. Most Randburg homeowners see a noticeable drop in their monthly utility costs after switching to gas, especially with current electricity tariffs.

Do I need a Certificate of Compliance (CoC) for a gas geyser?

Yes. South African law requires a gas CoC for every gas installation. This confirms the system was installed safely and meets SANS 10087 standards. You need a valid CoC when selling your property, and your insurance may not cover gas-related damage without one. We issue CoCs on every gas geyser we install.

Can you convert my electric geyser to gas?

Yes. We remove the old electric geyser, install a new gas unit, run the gas line, and connect everything to your existing hot water pipework. The changeover is usually done in a single day. We handle the full installation including gas piping, flue, and CoC certification.

Where should a gas geyser be installed?

Gas geysers must be installed outdoors or in a well-ventilated area. This is a safety requirement under SANS 10087. Common locations include outside walls near the bathroom or kitchen, in ventilated utility rooms, or on covered patios. We assess your property and recommend the safest, most practical position.

How long does a gas geyser last?

A quality gas geyser typically lasts 10-15 years with proper maintenance. The heat exchanger and burner are the main components that wear over time. Annual servicing (cleaning the burner, checking the flue, and testing the gas pressure) extends the lifespan and keeps it running efficiently.

My gas geyser pilot light keeps going out. What's wrong?

A pilot light that won't stay lit is usually caused by a faulty thermocouple, a blocked pilot jet, or wind interference at the flue outlet. The thermocouple is the most common culprit: it's a safety sensor that shuts off gas flow if it doesn't detect a flame. We carry replacement thermocouples and can usually fix this in under an hour.
