The Efficiency + Boiler is quietly heating more and more homes and small businesses across America and throughout the world. This quiet revolution in the light commercial boiler market is the product of years of research and development, which has resulted in a boiler that provides all the bells and whistles typically found on giant commercial boilers in a package small enough to fit in a closet. It operates on low gas pressure, doesn't require a chimney, monitors itself and does it all while saving energy and money!

The Mini-Fin Boiler combines the best of cast-iron and copper technology to create a more efficient, longer lasting boiler for residential heating applications. Plus, it's lighter than conventional boilers, so installation is easy, and it allows easy access to all major components for servicing. (Not to mention, it's competitively priced and comes standard with a 20 year Limited Warranty.) For reliability and simplicity at a competitive price, look to Mini-Fin.
