High Efficiency Duct Furnace

Energy efficiency upgrades and a new high efficiency heating system can often cut your fuel bills and your furnace s pollution output in half.

High efficiency duct furnace.

It moves the air with a circulating fan. Both models offer high effciencies that achieve annual fuel savings of up to 25 over conventional duct furnaces. Duct furnaces modine s gas fired duct furnaces are designed for both indoor and outdoor installations. 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.

Hastings duct furnaces feature our patented airfoil shaped heat exchanger with horizontal radiation. And it has a gas burner with electronic ignition although condensing furnaces may have more electronic controls. In this type of furnace 20 of the energy produced by natural gas is expelled as exhaust. 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.

Primary applications are for building heating cooling and make up air systems. How a high efficiency condensing furnace differs. Mrcool 70 000 btu 95 afue upflow horizontal multi speed low nox gas furnace with 17 5 in. These days 95 afue is a common rating among new gas powered furnaces.

Like a conventional furnace it takes in cold air from the house and runs it through an air filter. 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. Duct furnaces separate their combustion air form the air in the heated space. The qved bottom burner access with ceiling mount and qves side access non combustible floor mounted are power vented indoor duct furnaces.

High efficiency furnaces these furnaces are also known as 90 percent furnaces because they have an afue rating of 90. High efficiency furnaces offer 90 or more afue. Separated combustion duct furnaces are specifically designed for buildings with hostile atmospheric conditions such as high humidity or negative pressures. A standard efficiency furnace provides 80 annual fuel utilization efficiency afue.
