Venting & Combustion Air

As modern-day heating systems have become progressively more efficient, the necessity to provide proper venting has become critically important. By venting, we mean the removal of exhaust gases from the heating system through a traditional chimney, or a sidewall venting system. Today’s high-efficiency heating systems are a marvel of technology, and provide energy savings up to 50% greater than old-fashioned heating systems, but one thing that all high-efficiency heating systems have in common are fairly low flue gas temperatures.  This makes sense because we’re trying to extract every ounce of energy from the heating system, and not send it up the chimney! While these systems provide high-efficiency, the lower flue gas temperatures can cool and condense and cause a traditional venting system, such as a masonry chimney to prematurely fail. To accommodate today’s high-efficiency heating systems, we offer stainless steel chimney liners, as well as a variety of sidewall vented options (system dependent).


 

Chimney liners

Chimney liners are a great solution for solving many venting problems while still utilizing an existing masonry chimney. The chimney liners provided by Sippin Energy Products are high-quality, and professionally installed. They are also sized properly to accommodate the type of heating system in the home, with the design goal of achieving the best possible venting efficiency.

As stated above, the main reason chimney liners are required for masonry chimneys is to protect them from low flue gas temperatures. Because high-efficiency heating equipment extracts all of the available heat and sends it into your home, there is very little remaining heat left in the exhaust/flue gases. When the flue gases are vented through the chimney, they cool quickly, causing water vapor to condense within the chimney. In the case of a masonry chimney, this will quickly deteriorate any mortar joints, causing the chimney to prematurely fail.

 


Combustion Air Supply Systems

Today’s high-efficiency boilers and furnaces not only need to be properly vented, but they also need an adequate and consistent supply of fresh/combustion air. A furnace, boiler, or water heater all need to mix air with fuel to provide proper combustion, very much like your automobile. When a burner system is starved for air, it will run inefficiently, and unreliably. In many cases, heating systems are installed in spacious areas where there is adequate combustion air to accommodate safe operation, however if the space is compromised or reduced, combustion air must be provided to the heating system directly from an outdoor source. Not only does this ensure safe and reliable operation, it adds a tremendous energy savings by simply not consuming the warm ambient air that has already been heated by the system. Many homes also require combustion air systems due to variations in draft caused by a variety of forces acting upon the home, such as bathroom or kitchen exhaust fans, or attic exhaust fans. These devices will inadvertently affect the draft and combustion air quality on a home heating system.

Sippin Energy Products provides a number of quality solutions for combustion air systems, both motorized and non-motorized depending upon the application.
