95 Efficiency Furnace In Attic

Standard efficiency furnaces work a bit differently than high efficiency one.

95 efficiency furnace in attic. Unlike a lot of other furnace models the mrcool 95 afue furnace wastes a minimal amount of fuel. You need to invest in a powerful high quality and energy efficient heater like the 95 afue multi positional gas furnace by mrcool. A 95 efficiency furnace uses sealed combustion where the heating unit pulls air in from outdoors instead of using air. After the first heat exchanger is heated the second stage begins.

High efficiency furnaces aren t usually recommended for an attic. A furnace can suffer from a drop in energy efficiency if it s in an unconditioned space such as an attic. Trane 95 and 90 gas furnaces deliver at least 90 efficiency far exceeding the government minimum standard of 80 afue for new furnaces. It turns out that for many homes a very convenient place to place a furnace is in the attic.

These days 95 afue is a common rating among new gas powered furnaces. In the second stage the secondary heat exchanger extracts heat out of the hot. If that s the boat you re in you need to make a change. A standard efficiency furnace provides 80 annual fuel utilization efficiency afue.

If you have a furnace that is at least 10 years old it probably has an afue somewhere between 60 and 70 meaning up to 40 cents of every dollar you pay for fuel is wasted. There is a common misconception that this is not possible for high efficiency furnaces. Most of the issues that furnace might experience in an attic are due to extremely cold weather in this poorly insulated space. If you want to purchase a mid efficiency furnace for your home then the price profile for the equipment is similar with a downflow model compared to an upflow one.

As long as you have a fully insulated attic there are rarely instances when we would advise against an attic installation. The cost profile for a furnace in the attic is competitive. So a 95 furnace is more efficient than an 80. In the first stage gas is burned to heat the first heat exchanger.

High efficiency furnaces offer 90 or more afue. Conventional furnaces use only one they use a two stage process. In this type of furnace 20 of the energy produced by natural gas is expelled as exhaust. In this video my hvac contractor gilbert rosipal from airrite shows us the inner workings of a 95 efficient gas furnace.

You ll see the concentric pipe used.
