Choosing the Right Expansion Tank

Need help determining what size expansion tank you need? Whether you need a tank for your heating system, plumbing system, or a system that uses a well, our new Extrol calculator can tell you which model you need with just a few simple questions. For a heating system, you will need to provide the BTU load of your boiler and information on what type of heat you have, such as baseboard, radiators, or radiant heat. With this information, we can calculate which Extrol tank you need. For a plumbing system, you will need to know the size and temperature setting of your water heater to find out what Therm-X-trol tank will fit your system. Well-x-trol tank size depends on the GPM and horsepower of your circulator pump.

A large selection of Amtrol expansion tanks can be found at SupplyHouse.com. Feel free to try out our calculator in the Resource Center if you need help making your selection.
