Due to high efficiency furnaces having their own fresh air intake no air is drawn from inside your home.
Sealed combustion duct furnace.
Primary applications are for building heating cooling and make up air systems.
Where the furnace draws this air is the difference between standard atmospheric.
The sealed combustion furnace.
They are designed for use within a building s duct work with upstream air mover by others.
As we already mentioned this is one of its biggest benefits.
Finally going with.
These types of furnaces have a dedicated pipeline that runs directly from an outside vent into a sealed combustion chamber of the furnace and a sealed vent to the outside of the home for venting the toxic fumes from the combustion process.
Sterling introduces the nexus unit heater a leading edge condensing heat exchanger delivering up to 97 efficiency.
The separated combustion furnace is designed for use in building areas with negative pressure and or extremely dirty or mildly corrosive atmospheres.
Modine s gas fired duct furnaces are designed for both indoor and outdoor installations.
Both models offer high effciencies that achieve annual fuel savings of up to 25 over conventional duct furnaces.
Featuring a single stage two stage or full modulation firing rate this durable 316l stainless steel heat exchanger is available with both natural gas and lp gas flexibility also field.
The combustion chamber loses less heat to the outside making the furnace cost less to run.
The highest efficiency furnaces today combine sealed combustion with a second condensing heat exchanger.
Install the highest performing furnace that project funding will allow to meet the heating load of the project.
For combustion to occur the furnace needs to draw in air to mingle with the gas from the burners.
Duct furnaces separate their combustion air form the air in the heated space.
Sealed combustion also makes a furnace more energy efficient.
Indoor separated combustion duct furnace modine indoor separated combustion duct furnaces are designed and engineered to deliver superior performance in a variety of applications.
In furnaces that are not sealed combustion units backdrafting of combustion gases can be a big problem.
The highest performance combustion furnaces are sealed combustion direct vent condensing gas furnaces with an annual fuel utilization efficiency afue exceeding 94.
Also featured is the factory installed power venter and sealed flue collector that controls combustion and excess air during on cycles.
Reznor s sc separated combustion gas fired duct furnaces are designed to separate their combustion air from the air in the heated space.
