Oil Burner Expansion Tank Purpose

Our heating and cooling technicians will make sure each expansion tank is correctly installed and maintained to prevent water hammer high water bills and unnecessary wear on the water heater and plumbing fixtures.

Oil burner expansion tank purpose.

If this step is not taken when needed the waterlogged compression expansion tank will cause boiler leaks and improper even unsafe boiler operation. This video is part of the heating and. When the water cooled down the tank volume decreased but still maintained a full heating system. As the water expanded it filled the tank in the attic with the expanding fluid.

Draining water out of a waterlogged expansion tank is a common heating boiler service procedure used to replace a lost air charge. The expansion tank serves to provide space for water and air within the boiler system to expand and contract without damaging pipes or valves. If you notice more dust settling after running the furnace or air conditioner a leaky duct could be the problem. If the expansion tank is missing or not operating properly pressure in the system may cause the boiler s pressure relief valve to vent water.

It ensures that constant pressure is maintained within the pipes so they do not get. The boiler expansion tank absorbs the expanding water by allowing the air in the expansion tank to compress this prevents the pressure from building and allows the boiler to heat and cool without too mush pressure building up. A description of how the old style expansion tank provides a cushion for expanding water in a hot water boiler system. To do their job these tanks must be properly located sized piped into the overall system and should be checked annually.

Expansion tanks help reduce water hammer and help protect the plumbing system from stress and damage which leads to longer tank life. If the tank overflowed because of excessive fill the excess water spilled into the gutter of the attic. An expansion tank is designed to relieve pressure in both potable water and closed hydronic heating systems. Heating boiler expansion tanks are metal tanks of varying sizes that are installed to absorb the initial pressure increase that occurs when the heating boiler system warms up.
