The life expectancy of the average hot water cylinder is eight to twelve years. In order to get the most out of your cylinder, here are a few maintenance tips that can increase the efficiency and cleanliness of your water cylinder.
Check the temperature – It should be above 60°C at the cylinder (to prevent the growth of Legionella bacteria) and no more than 55°C at the tap (so you don't get burnt). Depending on your cylinder, you may need to call Maxey Plumbing to adjust your thermostat. Even an extra 10°C on the thermostat of your hot water system could be costing you $30 a year.
Insulate your cylinder – depending on the age of your cylinder having a properly insulated water cylinder can dramatically improve the efficiency of the unit. If the unit is not already properly insulated, we recommend considering having the insulation put in. It will definitely save you money in the long run.
Flush the system – This can be a relatively complicated procedure, so be sure to give Maxey Plumbing a call to flush the system once in a while (about every 1 to 3 years, depending on what type of water cylinder you have). Flushing the cylinder cleans out built-up sediments that decrease the efficiency of the unit.
Check the Expiration Date – Many people are unaware of the average life expectancy of their home water cylinder. If your hot water cylinder is more than eight years old, it is time to consider changing the unit. If it is older than twelve years, it more than likely has to be changed not just for energy efficiency, but for your health and safety.
By following these five simple suggestions, you will be able to make sure that your water cylinder is running as smoothly and efficiently as possible. You will also be able to ensure that the water you are drinking and cleaning with is clean.
