Condensing Boilers | Building America Solution Center

Today, systems using condensing boilers should be designed with the lowest hot water supply and return temperature feasible while still adequately heating the space. It should be noted that hot water return temperature is the driving factor that dictates boiler efficiency, so optimizing the hot water return temperature with this consideration should be the goal.

Condensing boiler - Wikipedia

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted., which would otherwise have been wasted.

Condensing Hot Water Heaters from Automatic Heating

Condensing Boilers and Water Heaters offer several significant advantages: The "Greener" boiler technology utilised in condensing systems recovers latent heat from flue gases and uses that additional energy to preheat return water which can lead to gross operating efficiencies of up to 98%. By using Condensing Technology, operating costs
