A storage geyser combines the two things you least want together: mains electricity at high wattage, and water. Modern units are well protected, but that protection depends on installation and maintenance being right. These are the points that matter.
Proper earthing is not optional
A geyser must be connected to a genuine earth, not just a three-pin socket that happens to have an earth pin. If your bathroom circuit has no verified earth, that needs correcting before anything else. Fit an RCD or ELCB on the circuit: it disconnects the supply within milliseconds of a leakage current, and it is the single most effective safety device you can add.
Give it its own circuit
A 15 to 25 litre geyser typically draws 2,000 to 3,000 watts. Running it on a shared lighting circuit or through an extension lead is a fire risk. It should have a dedicated line from the distribution board with an appropriately rated MCB and an isolating switch outside the bathroom.
Do not leave it on continuously
Leaving a geyser switched on all day relies entirely on the thermostat never failing. Thermostats do fail, and the backup is a thermal cut-out that is only there for emergencies. Switch it on twenty to thirty minutes before you need hot water, and off afterwards. Your electricity bill will thank you too.
Check the pressure release valve
Every storage geyser has a temperature and pressure relief valve. If it is blocked or has been sealed by scale, pressure has nowhere to go. Once every few months, lift the lever briefly and confirm water discharges freely, then reseats. If nothing comes out, or it keeps dripping afterwards, have it replaced.
Descale annually in hard-water areas
Hard water leaves scale on the heating element and inside the tank. Scale makes the element run hotter than designed, which is how elements burn out, and it eats into the magnesium anode rod that protects the tank from corrosion. An annual service should include descaling and an anode-rod check — a corroded anode is the reason older tanks start leaking.
Warning signs to act on
- A mild shock or tingle when touching the tap or the shower fitting — switch off at the MCB immediately and call an electrician.
- Water that will not get hot, or gets far too hot.
- Rust-coloured water from the hot tap.
- Any water dripping from the body of the unit.
- A burning smell, or discolouration around the electrical connection.
Never attempt to open a geyser yourself while it is connected. The tank holds water under pressure and the element terminals stay live until the circuit is isolated at the board.
