What can affect immersion heater performance?
Something that can affect their performance is limescale in hard-water areas. A lining of calcium carbonate (limescale) grows thicker over time on the heating elements of the immersion rod. If this becomes too thick, the heat generated by the heater element can’t be transferred into the surrounding water. This trapped heat builds up in the immersion heater rod causing it to burn-out and ultimately fail.
What can affect the cost of electric water heating?
Check that your immersion heater is thermostatically controlled – this is very important – otherwise it will be overheating your water which will cost more. If your water is scalding hot, then it may not be working correctly. Having an insulated cylinder is important too, most modern hot water cylinders are pre-insulated. If yours isn't, consider buying an insulated jacket to keep the water warmer for longer, so you’ll use less kilowatts (money!) to bring the water back up to the required temperature. Remember you need to heat the water in your immersion heater to above 50°C to kill off bacteria.
