Efficiency Standards for Boilers. Boiler efficiency ratings start at 82 to 84% for gas or oil systems that meet federal minimums and go up to 95% for high-efficiency condensing units. As a general rule, natural gas has a slight edge overheating oil. Efficiency also depends on the system's design.
For example, if the input rating is 100 MBH and the DOE heating capacity is 80 MBH (80% efficient) and the boiler is installed at an elevation of 9000 ft then the derating process should adjust the input to 64 MBH, i.e. 9000 ft = 100 - (100 * (9 * .04)) = 64.
So "efficiency" in a practical not textbook reference is a much broader subject than just the AFUE. I chose to put in Smith boilers because the AFUE is very good, the boiler is very servicable, life span is exceptional and the initial cost to install is the same or less than any other American cast-iron boiler. Dave Mayer Sr.
Boiler Efficiency Ratings (SEDBUK) Why is Boiler Efficiency Important? Boilers account for around 55 per cent of your yearly annual energy bills, so improving your boiler's efficiency could make a big difference to your household costs. Efficient boilers produce less C02 and use less fuel, which in turn helps to cut your heating bills.
efficiency. Boiler efficiency, in the simplest terms, represents the difference between energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units will result in substantial fuel savings.
Companies use fuel efficiency ratings to determine whether a boiler is standard-efficiency or high-efficiency. Fuel efficiency ratings also tell you about how much a boiler will cost to operate during the year. This will give you an idea of the cost of your boiler over time. Standard-Efficiency Boiler. A standard-efficiency boiler means the
