ENERGY STAR Certified Boilers | EPA ENERGY STAR

Lifetime energy costs - Values represent the sum of the discounted value of annual energy costs, based on an assumed boiler life of 25 years. Condensing boiler annual energy use - Adjusted for an assumed boiler operation of 50% condensing mode versus 50% noncondensing mode.

Boiler Efficiency: Which Boilers Are Most Energy Efficient

• Condensing heat recovery is a proven, commercially available cost effective technology • Offers significant un-tapped energy saving potential for boiler applications. Could be applied to recover latent heat from paper machine hoods, dryers and gas turbine/HRSG exhaust. • Natural gas prices above $5 per MMBtu offer attractive payback

How to improve the energy efficiency of boiler systems

Mar 19, 2021 · The gas condensing boiler has the characteristics of energy saving. It adopts the condensing recovery device to recover the heat discharged from the tail gas of the boiler and reuse the heat energy. This not only improves the thermal efficiency of the boiler, but also reduces fuel consumption and achieves the effect of energy saving. 3. Environmental pollution is small

The Best Condensing Boilers In 2021 - HomeSage

Feb 10, 2021 · Modern boilers are more efficient for several reasons, but their main advantage is that they are all condensing boilers. A condensing boiler has a larger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient. Sometimes the flue gases get so cool that the water vapour in the gas condenses out, and even more energy is recovered from the condensing vapour.

Jan 08, 2016 · If all vapor could be condensed, approximately 10,100 Btu/therm of gas consumed would be released resulting in 10 percent energy gain. The amount of latent heat recovered depends on the flue gas temperature. The lower temperature the more latent heat is released.

Maximize Boiler Heat Recovery with Condensing Economizers

Feb 08, 2019 · For condensing boilers, you need a return water temperature of 80°F or lower in order to achieve 97% efficiency. (Look at the efficiency curves from any common condensing boiler manufacturer to see this.) Put another way, you start gaining efficiency only when your return water temperature is approximately 135°F or lower. See the graph below.
