How Geyser Installation Works – Step-by-Step
Thinking of installing a new geyser in your home or business? At Gauteng Geyser Experts, we make the process smooth, safe, and stress-free. Whether you’re replacing an old unit or doing a fresh installation, our trained technicians follow industry-best practices and SANS specifications to ensure everything works perfectly — and lasts.
Here’s a simple breakdown of how our geyser installation process works:
Step 1: Free Consultation & Geyser Assessment
We start by understanding your needs. Do you need a gas, electric, or solar geyser? How many people live in your home? What’s your current hot water demand? Based on this, we recommend the best geyser size and type — whether it’s a 100L Kwikot, 150L Heat Tech, or 200L Duratherm unit.
This ensures energy-efficiency, water pressure balance, and long-term reliability.
Step 2: Choosing the Right Location
Next, we identify the safest and most efficient place for installation. This could be in the ceiling, outside wall, or roof. For solar and gas geysers, we consider ventilation and sun exposure. We also ensure easy access for maintenance.
📍 We work in all areas of Gauteng including Pretoria, Johannesburg, Centurion, Midrand, Alberton, and Randburg.
Step 3: Removing the Old Geyser (if replacing)
If you’re upgrading or replacing a faulty unit, we’ll carefully disconnect and remove the old geyser, safely disposing of it according to local regulations.
We also check your existing plumbing and wiring to make sure it’s compatible with the new geyser.
Step 4: Installing the New Geyser
This is where precision matters. We mount the geyser securely, connect the hot and cold water pipes, and ensure all fittings are sealed and pressure-tested. For electric geysers, we wire the unit to your DB board. For gas or solar, we connect regulators, panels, or timers as needed.
All installations are done by certified professionals with years of experience.
Step 5: Safety Checks & Compliance
We follow SANS 10254 and other relevant safety codes, ensuring your installation is compliant with South African regulations. This includes checking:
Safety valve and drip tray
Pressure control valve
Isolator switch (for electric units)
Ventilation and leak checks (for gas units)
Earth leakage protection
Safety first — no shortcuts!
Step 6: Testing the System
We fill the tank, power up the geyser, and run full tests to check for leaks, proper heating, water pressure, and electrical/gas performance. Everything must be running smoothly before we wrap up.
Step 7: Handover & Aftercare
Once installed, we walk you through the system, how to operate it, and what to watch out for in the future. We also leave you with a warranty, compliance certificate, and tips for maintenance.
We’re always available for follow-up support, maintenance, or questions — just give us a call!
