Proper hot water heater service annually, by a professional plumbing company, will keep your appliance operating efficiently for years. There is not much to do when it comes to maintaining the unit but it is a maintenance area that is the most overlooked in the home. There are different types of units which require different maintenance.
While performing water heater service the maintenance technician will check for potential or existing leaks, rust or corrosion. He or she will make sure that the temperature pressure relief valve, in tank types, is firmly connected to a pipe that reaches within 6 inches of the floor. The temperature adjustment will also be checked to be 120-130 degrees Fahrenheit. These simple steps will give you the 10 to 14 years of service expected from your tank type unit and 20 years from your tankless heater. To make your heater more efficient, wrap any exposed hot water pipes with insulation. This will keep your unit working less and producing more and will also add to its life expectancy.
