    About AMTROL

    AMTROL was founded in 1946 on the premise that innovation, quality and service will be rewarded with customer loyalty and support. In 1954, we revolutionized the hydronic industry when we introduced EXTROL, the world's first pre-pressurized diaphragm expansion tank. This was followed in 1963 with the invention of the first pre-pressurized well tank and in 1967 with the invention of the refrigerant gas cylinder. AMTROL went on to invent the indirect fired water heater in 1980 and the thermal expansion tank in 1991. More recently the company introduced the first composite metal LP gas tank in 2005 and has since sold over 1 million of these tanks around the world. Throughout our history, AMTROL has been the world leader in the design and operation of the vital mechanical systems that are used to control hydronic heating and to store potable water.

    Today, that same spirit of innovation is part of every water heater, pressure booster, well tank and chemical container we manufacture. Over the years, we've continuously raised our stringent quality standards to even higher levels, to keep pace with the industry's rapid technological advancements, and to help us achieve ISO 9001:2008 certification.

    AMTROL products include water system solutions for storage, treatment, heating, expansion and flow control, along with a host of related HVAC products serving the residential, commercial, and industrial markets. Our subsidiaries include AMTROL Alfa, in Portugal, specializing in heating and refrigerant gas cylinders. AMTROL employs 1700 people worldwide.

    Our corporate headquarters are in West Warwick, Rhode Island; our products are manufactured in Rhode Island, Maryland and Kentucky and internationally in Portugal. To meet the international demand for our products, we operate a sales office in Canada as well as sales offices in Latin America and Europe.
