Furnaces operate with relatively low efficiencies (as low as 7 percent) compared to other combustion equipment such as the boiler (with efficiencies higher than 90 percent. This is caused by the high operating temperatures in the furnace. For example, a furnace heating materials to 1200 oC will emit exhaust gases at 1200 oC or more, which

A little under sizing or over sizing is fine, just don't over size by more than about 20% of your heating requirement, or short cycling can occur which wastes energy and reduces your comfort. If you're still unsure which system size is right for you, please e-mail us or call our toll free number at 1-866-862-8922.

Step 5. Divide the result from Step 4 by 12,000 to determine the tonnage requirement of the furnace. In the example, you would divide 35,000 by 12,000 and get 2.92. This home would require a furnace that has a tonnage of approximately 3. Tip. Furnaces are not 100-percent efficient, which means that you'll need a furnace with a higher tonnage

Then, to calculate the output on a given gas furnace, multiply it's efficiency rating by it's listed input rating to determine the actual Btu output of heat. For example, if a furnace has a listed input rating of 90,000 Btu's and an efficiency

system capacity by 1% for R-22 and 0.6% for R-410A per psi. This can be a serious problem if suction lines are not sized properly and pressure loss is 8 or 9 psi. Therefore, in order to minimize capacity loss and maximize efficiency, suction pressure loss must be minimized. This is achieved by increasing the size of the suction line.
