The thermal expansion tank is certified to nsf ansi 61 dhot 140 f and pressures to 150 psi.
Water heater thermal expansion tank.
Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering.
The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater preventing excessive water pressure.
At the top it has an air valve like the one seen on most tires called schrader.
The expansion tank serves as a backup system to prevent overworking your plumbing.
The water heater expansion tank serves as an overflow receptacle by absorbing excess water volume that occurs when water is heated as well as absorbing fluctuations in the incoming water supply pressure.
The excess water volume instead of causing too much pressure on the plumbing rushes into the expansion tank and lowers the pressure in the water heater to safer levels.
This ultimately protects it from damage.
A water pressure gauge sizing expansion tanks for water heaters can be a complex engineering challenge but residential expansion tank sizing has been simplified through the use of calculators.
We offer a range of expansion tanks for potable and non potable applications.
Water expands by roughly 2 as it heats up from 50 f to 120 f.
You install the expansion tank down the line from the inlet valve that sends hot water into your home.
A water heater expansion tank is another small tank that is attached to the water supply pipe of the water heater.
At the bottom there is a threaded pipe connection.
With a properly installed tank the system pressure will be maintained and will help prevent added stress to various components saving you headaches and money down the road.
This water heater expansion tank stops hot water from backflowing into the cold water line and prevents hot water from escaping through the pressure relief valve and onto the floor.
New or larger expansion tanks may be needed due to pressure reducing valves check valves and backflow preventers added to the community s water system.
They are used to absorb excess water pressure which can be caused by thermal expansion as water is heated.
When your water thermally expands a water heater expansion tank prevents unwanted increases in pressure.
Water heater thermal expansion tanks.
Common residential expansion tank looks like a small propane tank.
The sizing chart will allow you to choose the correct size expansion tank for your application.
Do not use a standard tank.
Thermal expansion tanks eliminate this wasteful costly and dangerous practice.
A thermal expansion tank is designed to help protect potable drinkable hot water systems helping to maintain them and keep them working efficiently.
What is a thermal expansion tank like.
Constant fluctuations in water pressure can be dangerous and they can damage the water heater properly installing a thermal expansion tank can solve all these issues.
Expansion tanks when water is heated it expands due to a phenomenon known as thermal expansion.
