Here water heater expansion tank insulation including end suction plan, air cooled chilled details , chilled water treatment station ,expansion tank insulation details expansion tank installed on the water supply pipe to the water heater. Its purpose is to deal with thermal expansion of water as it heats up in the water heater - to prevent water pressure from getting too high. he expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater, preventing excessive water pressure. If water pressure gets to high it can damage valves in plumbing fixtures, joints in supply pipes and the water heater itself. Thermal expansion tanks and pressure/temperature relief valves provide valuable fail safes when the pressure in the tank is too high. They allow water and pressure to escape and levels in the tank to return to safe ranges. However, if they fail to function properly, the tank can burst. for more details of water heater expansion tank insulation.
