The Aqua-Therm Coal-One boiler is designed to provide the reliability, durability, increasing heat output and reduced emissions of our Aqua-Therm Eco-One boilers while allowing you to use coal in areas where wood burning is not allowed.

If State or local regulations have made burning wood impossible or too costly to afford an EPA compliant boiler, cheap easily sourced coal may be the answer for you!

Our Coal-One model boilers features a rear mounted and door mounted fan and our redesigned, 2-stage baffle.

Solid, reliable design and construction, great performance, affordability, and a Limited Lifetime Warranty have made these boilers a hit with our customers.

Aqua-Therm Coal-One boilers are available either Unsheltered or Sheltered and in two sizes to provide lots of hot water for a wide variety of residential and commercial applications.
