Features
- USA Made
- All SX thermal expansion tanks are made in the USA.
- Heavy Duty Tank
- From the deep drawn steel tank to the water-tight reservoir for expanded water, this thermal expansion tank is constructed for maximum strength and efficient energy consumption.
- Eliminates Wasted Energy
- Expanded water caused by thermal expansion is collected by the SX tank which returns the water back to your system which preventing faucet drips, intermittent toilet fill, and pressure relief valve discharge.
- Protection for Your System
- SX thermal expansion tanks are designed to protect your water heater, fixtures, and appliances by preventing dangerous pressure build up.
In 1954, Amtrol invented the first expansion tank to control pressure build-up and energy consumption in heating and chilled water systems. More than 50 years later the SX is still the one of the world?s leading floor-standing expansion tanks and is proudly made in the USA! The SX vertical boiler system expansion tank collects expanded water as system temperatures rise, reducing potentially dangerous pressure build-up. Equipped with a 100 percent tested sealed air cushion, water-tight reservoir, air stem for pre-charge adjustment, and a deep drawn steel tank, the SX is reliable and built to last. The SX-30V is ideal for large residential and light commercial applications and can be used with high output boilers.

Amtrol SX-30V Reviews & Ratings

Review Posted 11/13/2018
I’m happy, happy, happy, and warm. I bought from eComfort a boiler system in August 2018 to replace a 60 year old Hot Water Gas Boiler for a house I purchased in Western Pennsylvania.
I am thrilled with the performance for efficiency, quietness, and instant heat to CI Radiators in a 3 story house with 6,200 sg/ft of living space.
There were no issues ordering online and having it delivered to my doorstep from the trucking company with a tailgate. It is heavy but my son and I were able to dolly it into the house fairly easy.
I was able to install myself without any difficult issues. This included removal of old furnace and then plumbing in the new furnace, fitting the exhaust/damper into the existing chimney work, and installing a must have ¾ gas line for maximum delivery of natural gas to furnace.
