The reality is that almost nobody changes it. Service techs rarely warn and owners don’t know it exists. When we do a first service on a heater older than five years, the anode is almost always fully consumed. Almost nobody knows it exists, but it’s the part that adds the most useful life to the heater. It’s a magnesium rod inside the tank that draws corrosion to itself instead of letting it attack the tank walls. It wears down over time. Once it’s fully spent, corrosion starts eating the tank and from that point every year matters. It should be replaced every four or five years in hard-water territory. Reasonable cost and easily ten more years of life. Water takes longer to heat than in the first year. It comes out hot at first and cools quickly. You see an unusually high electricity bill. There are kettle-like noises that mean sediment bubbling at the bottom. The first few seconds of water look slightly cloudy. Any of these symptoms warrants a service.

30 days on labour plus the manufacturer’s official warranty on the installed unit. We always replace old flexible hoses and the safety valve to prevent later leaks. Removal of the old unit, fitting of the new one, electrical and water connection, full function test.

The reason is limescale building up inside the tank. The heating element gets coated with a thicker and thicker layer that acts as insulation. The thermostat sees the target temperature isn’t being reached and pushes more current. The bill goes up, the unit heats less efficiently, and eventually the element burns out. Sometimes the tank ruptures internally and the catastrophic leak floods the utility cupboard.
