High Efficiency Duct Furnace

Primary applications are for building heating cooling and make up air systems.

High efficiency duct furnace.

In this type of furnace 20 of the energy produced by natural gas is expelled as exhaust. These days 95 afue is a common rating among new gas powered furnaces. Power vented furnaces with a balanced flue design ensure complete combustion at all operating conditions. Energy efficiency upgrades and a new high efficiency heating system can often cut your fuel bills and your furnace s pollution output in half.

Both models offer high effciencies that achieve annual fuel savings of up to 25 over conventional duct furnaces. The qved bottom burner access with ceiling mount and qves side access non combustible floor mounted are power vented indoor duct furnaces. Like a conventional furnace it takes in cold air from the house and runs it through an air filter. Upgrading your furnace or boiler from 56 to 90 efficiency in an average cold climate house will save 1 5 tons of carbon dioxide emissions each year if you heat with gas or 2 5 tons if you heat with oil.

Duct furnaces separate their combustion air form the air in the heated space. Mrcool 70 000 btu 95 afue upflow horizontal multi speed low nox gas furnace with 17 5 in. While the condensing furnace is different in its design and repair needs it does have some similarities to a conventional furnace. This means that 10 percent or less of the possible energy found in the natural gasthat can be used for heat is lost during the combustion process due to venting.

Duct furnaces modine s gas fired duct furnaces are designed for both indoor and outdoor installations. High efficiency furnaces offer 90 or more afue. The hastings istd indirect gas fired duct furnace high efficiency tubular design heat exchanger has a wide range of mbh inputs from 100 mbh to 400 mbh with an output efficiency rating of 80 with selected airflows required to meet selected application. High efficiency furnaces these furnaces are also known as 90 percent furnaces because they have an afue rating of 90.

How a high efficiency condensing furnace differs. And it has a gas burner with electronic ignition although condensing furnaces may have more electronic controls. A standard efficiency furnace provides 80 annual fuel utilization efficiency afue. Separated combustion duct furnaces are specifically designed for buildings with hostile atmospheric conditions such as high humidity or negative pressures.
