Benefit on your new heating system with sealed combustion efficiency.
Many brand name manufacturers today provide over 95% AFUE ratings or efficiency model units.
Eliminating your old gas furnace from possible back drafting within your home. Safety is Priority #1.
Most importantly, newer furnaces of today provide a built-in safety factor reducing possible carbon monoxide poisoning through any draft opening and/or open burner type system caused by unwanted and possibly dangerous negative pressure imbalance from within your home. The enclosure of the burner compartment is sealed from within your home for its combustion process.
With two-pipe, direct vent type systems, combustion air intake/exhaust comes directly from outdoors rather than from within your home. For example, combustion air, is air required to replace “indoor air” for the combustion or burning process of any fossil fuels such as gas or wood burning appliance. This combustion air enters your home from an opening to the outdoors.
Your application will vary depending upon its contractor. HVAC contractors in Minnesota are not required to have any formal training from an accredited or approved educational vocational institution related to their field of work. Always research your application based on quality of workmanship, performance of operation and experience of its installer.
90%+ efficiency natural gas furnaces are condensing units, on average, when operating, will drain up to 5 gallons of water on a cold winter day. Due to its featured design, the condensing chamber or secondary heat exchanger will be positioned below your primary heat exchanger and above your main blower fan motor. Hence, dropping its rate of temperature below its dewpoint causing a temperature conducive to saturation, moisture or water. This process raises its efficiency factor by recovering more btus or heating capacity available for your home. Over .95 cents of every heating dollar is spent heating your home rather than thrown away up your chimney to the outdoors as with many older less efficient models.
Always remember that HOME PERFORMANCE is a key factor to optimum heating and cooling efficiency. This includes sufficient attic insulation (up to R-50), non obstructive soffit and roof ventilation, sealed vapor barrier, etc. Replacing an older furnace, without these key factors may compromise your overall performance and optimum long term energy savings.
Two pipe vent (direct vent) dedicated to outdoors are highly recommended. An operable floor drain or water drain outlet is highly recommended for proper condensate removal when in operation. If no floor drain is accessible, a water (condensate) pump w/safety switch will be required.
There is no need to apply additional combustion air as required in many states for furnace only operation. Other gas appliances may require combustion air within your home. There is no further need for a “chimney” for venting purposes such as with any 80% AFUE type furnaces. Therefore, minimizing any rust, corrosion and maintenance of vent pipe including downdraft problems within your existing chimney.
In conclusion, on average, for every heating dollar spent, .90 cents will be spent heating your home. Many furnace manufacturers also provide additional energy savings with an energy efficient ECM or Variable Speed Blower Fan Motor. Savings upward of 70% on your furnace fan blower operation. On average, the cost of operating a 100w light bulb annually. 2013 Best Buy. For more information visit http://tcheatingair.com/Home.html
