  • Condensing Steam Boiler: Are they worth it?

    According to GSA, the combustion temperature for condensing boilers is 130 degrees Fahrenheit. On the other hand, non-condensing boilers perform at 356 Fahrenheit!! Using a condenser boiler over a non-condenser will do the job in less amount of heat. In non-condensing boilers, the combustion or exhaust gases go into the flue, and some heat is Get Price

  • Best Condensing Boiler Reviews 2022

    Dec 31, 2021 · Condensing boilers are water heaters fueled by gas or oil.
