Understanding Residential Boiler Efficiency Ratings | Weil-McLain

Understanding Residential Boiler Efficiency Ratings. Boiler efficiency is measured by annual fuel utilization efficiency (AFUE), for units under 300,000 BTUH input. The Federal Trade Commission requires new boilers to display their AFUE so consumers can compare heating efficiencies of various models.

Steam Accumulators and Steam Boiler Response to Load Changes

Boiler Response to Sudden Steam Demand Steam boilers seem to operate efficiently with good steam quality when subjected to a steady steam demand at a rate matching the output of a boiler. Consequently, when a steam system valve opens quickly, a rapid steam load demand occurs, and the boiler will depressurize. When

Forbes Marshall > Knowledge > SteamPedia > Boiler Efficiency

The indirect efficiency of any boiler is specified at 100% load. But practically no boiler operates at 100% load. Hence in actual the committed efficiency will never be achieved. In reality the efficiency of the boiler falls down at lower loads. Since boilers rarely operate at full load conditions the actual efficiency figures achieved are

Condensing Boiler - Air Conditioning, Heating and

Condensing boilers can achieve greater efficiencies because they capture more heat from the exhaust gases than a conventional boiler. To do this, a condensing boiler has a larger heat exchange surface to enable it to transfer as much heat as possible from the boiler's burner into usable heat, thereby allowing less heat to escape as exhaust gases.

Best Value/Most Reliable boiler? | Terry Love Plumbing

But really, the heat load on the boiler is about 36-37K, not the contractors' calculated 50K- 58K. If you project down to -10F for 70F heating degrees (base 60F), the heat load at -10F is 70F x 737 BTU/degree-hour- 51,590 BTU/hr finally hitting the range of their calculated numbers at much higher temps. While it might hit -10F during a Polar

Efficient Boiler for Small Heat Load and Multiple Zone Types

By using a HW heater as the heat source it's inherently buffered, and can't short-cycle no matter how small the zone/heat-load, and there are NO modulating burners (mod con or combi) out there that will modulate below even the design-condition heat load of the smallest zone, let alone the zone's average heat load.
