BOILER SERVICE IN CHICAGO
Space heating energy costs account for roughly 25-30 percent of the total energy costs for a typical commercial building. High-efficiency boilers can reduce heating costs by 10 percent and in many cases by as much as 20 to 30 percent. The best tip we can give Chicago homeowners is to have a tune up service or preventive maintenance performed on their heating system to keep operating cost low. When your boiler starts giving you trouble, call A Custom Services Inc for boiler service in Chicago. Our boiler repairs team responds quickly and professionally to all home heating repair calls. We enjoy our work and it shows! We look forward to welcoming you as a customer and being your preferred repair company whenever you have a boiler problem in your home.
A boiler replacement that reduces gas consumption by 20 percent could save about five to 10 cents per square foot annually.Boilers are available in two efficiency ranges: around 80 percent for standard conventional boilers, and percentages in the 90s for energy-efficient condensing units.
The dividing line between these efficiency ranges is based on the boilers ability to withstand condensing flue gases. Condensing flue gases, which occur in high-efficiency boilers, require special design considerations to tolerate the corrosive effects of the condensate. Boiler efficiency is defined as how much of the heating value of the fuel is being converted to useful heat.
Condensing boilers absorb more heat from combustion gases, allowing the water vapor to condense and therefore providing increased efficiency. Any hydrocarbon fuel burned in a boiler, whether it is propane, natural gas, or fuel oil, produces water vapor during the combustion process.
Conventional boilers are non-condensing boilers with materials that cannot tolerate the corrosive properties of condensing flue or stack gases. Conventional boilers operate around 80 percent efficiency, compared to over 90 percent efficiency for condensing efficient boilers. Other factors also influence boiler efficiency, including boiler shell losses, piping losses, and cycling losses.
FIRE TUBE AND WATER TUBE
Boilers use water to absorb heat from a burned fuel/air mixture. Boilers can produce steam or hot water. The two most common types of boilers are fire tube and water tube.
Fire tube boilers typically consist of a series of straight tubes that are housed inside a water-filled outer shell. As hot gas flows through the tubes it heats the water that surrounds the tubes.
Water tube boilers are designed to circulate hot combustion gases around the outside of a large number of water-filled tubes. Newer boilers have tubes with complex and diverse bends and fins to maximize the heat transfer area.
Because the water/steam pressure is confined inside the tubes, water tube boilers can be fabricated in larger capacities than fire tube boilers and are often preferred for higher-pressure steam applications.
