Incorporate Minimum Efficiency Requirements for Heating

Mar 16, 2020 · High efficiency boilers, which have an annual fuel utilization efficiency (AFUE) of 90% and above, use condensing technology. These boilers work by recovering heat from the flue gases that simply exit a house from the flue of a conventional non-condensing boiler. They condense the water vapor from those gases and recover heat that would

FERROLI - Boilers

Non-condensing hot water boilers are the traditional commercial facility default option. These boilers do not allow combustion gases to condense in the heat exchanger, which is typically cast iron. They require a return water temperature of around 140ºF to ensure no condensation forms and that there is no thermal shock to the boiler.

How to Adjust the Water Temperature of a Hot Water Boiler

Sep 14, 2015 · Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water quality is a critical aspect of implementing and operating an efficient steam plant.
