Oil Burner Expansion Tank Purpose

To do their job these tanks must be properly located sized piped into the overall system and should be checked annually.

Oil burner expansion tank purpose.

If the tank overflowed because of excessive fill the excess water spilled into the gutter of the attic. It ensures that constant pressure is maintained within the pipes so they do not get. An expansion tank is designed to relieve pressure in both potable water and closed hydronic heating systems. A description of how the old style expansion tank provides a cushion for expanding water in a hot water boiler system.

A system that applies inert gas pressure typically nitrogen at the expansion tank to prevent oxidation of thermal oil and or to create system pressure to overcome height restrictions for an expansion tank. The expansion tank serves to provide space for water and air within the boiler system to expand and contract without damaging pipes or valves. A vessel that cools thermal oil before it enters an atmospheric expansion tank to help minimize oxidation of the oil. If the previous solutions haven t reduced the level of dust it might be time to.

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. 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. Draining water out of a waterlogged expansion tank is a common heating boiler service procedure used to replace a lost air charge. If this step is not taken when needed the waterlogged compression expansion tank will cause boiler leaks and improper even unsafe boiler operation.

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. If you notice more dust settling after running the furnace or air conditioner a leaky duct could be the problem. As the water expanded it filled the tank in the attic with the expanding fluid.
