Boiler Seasonal Efficiency
ARCHIVED - Energy Efficiency in Buildings
Both Aerco and Viessmann, the manufacturers of the condensing boilers reviewed here, claim seasonal efficiencies as high as 95 percent. The cost for a 1000-MBtu/hr boiler ranges from $25,000 to $35,000, not including installation. Mid-efficiency boilers have a much lower initial cost ( i.e., $10,000 to $20,000 for a 295- kW [1000-MBtu/hr] boiler).

Annual or Seasonal Efficiency Seasonal efficiency cannot be tested in the field, nor can it be described with a simple equation. In addition to stack losses and jacket losses, seasonal efficiency accounts for heat loss during periods that the boiler is "idling" to maintain its internal temperature while the building is not calling for heat.

BOILER EFFICIENCY DEFINITIONS An oversizing factor, which means the boiler does not run at full capacity, even on the coldest day. Seasonal efficiency is the closest approxima on of the boiler's actual performance in a par cular build-ing. The AFUE ra ng system makes simplifying as-sump ons that may not apply to a par cular instal-

AFUE much more closely represents peak efficiency, and the energy wasted when the boiler shuts off really cuts down the annual efficiency. Comparing the 83.5% AFUE tankless coil boiler at right, System 2000 will cut fuel bills by over 43%…although there is only a 4% difference in AFUE ratings. This means the tankless coil boiler will burn 77%

Oct 25, 2016 · SEDBUK once stood for Seasonal Efficiency of Domestic Boilers in the UK, and it was a great way of seeing, at a glance, how efficient a boiler was and exactly what you were getting for your money! This simple rating system was first introduced in 1999, by boiler manufacturers and the government. Since it's introduction, the system has been

Seasonal efficiency is how well the boiler uses fuel over the entire heating season. It is the ratio of the total seasonal heat output used by the facility to the total seasonal fuel input. The seasonal efficiency depends on the boiler's steady-state efficiency, standby …

Comparing the efficiency of electric, gas and oil boilers side-by-side can be challenging because despite being 99- efficient, electric boilers tend to have an ErP rating of D. On the other hand, all condensing gas and oil boilers must reach a minimum efficiency level of 92%, yet this is enough to award them an ErP A-rating. Manufacturer.
