Total System Efficiency with Condensing Boilers

Condensing Boilers

In condensing boilers, there is a direct correlation between increasing condensation of the flue gas and boiler efficiency gains. Boilers are closed pressure vessels that are used to heat fluids -- either water or steam. They range in size, fluid to be heated, temperature of fluid and design configurations. This paper is the first in...

Gas Technology: Condensing Hydronic Boilers

hydronic boilers

The key to 99% efficiency is having incoming feedwater below 140° F and modulating the boiler — or having sufficient redundancy to achieve the “sweet spot.” Getting the most for your energy dollar It’s a clever idea. Condensing hydronic boilers can operate at efficiencies in the mid‐90s and above. The key to these fantastic efficiencies...
