Cold mains water hitting the element at the start of the heat cycle puts thermal stress on an already-corroded element and a tired thermostat. Anode rods that have been depleted for two summers finally let go in mid-July when the geyser is working twice as hard. A pre-winter PIRB inspection (anode, P&T valve, element resistance) catches most failures before the burst, which is the cheapest possible outcome.

Yes — replacing a fixed-installation geyser requires both a SANS 10254 plumbing CoC from a PIRB-registered plumber and an electrical CoC from a Department of Labour-registered electrical contractor. Insurance claims for water damage post-burst routinely fail when these certificates are absent or out of date. Insist on both at handover and store them with your house file.

A 150L geyser comfortably runs two short showers back-to-back plus a basin and dishwashing cycle; a 200L gives you three showers plus a bath without lukewarm complaints. For a family of four with morning peak demand, 200L is the right answer unless ceiling space or load-bearing limits push you back to 150L paired with a heat-pump booster or solar pre-heat.

A like-for-like swap on an accessible geyser is typically 3–5 hours including drain-down, mounting, plumbing, electrical and the CoC sign-off. Water is usually off for 2–3 of those hours. A relocation or a first-time install (new geyser tray, new circuit, new trip switch) is a full day's job; the plumber should give you a written window before starting.
