how does a condensing gas furnace work

Burners inside the furnace ignite creating heat thats captured by the heat exchanger. Modulating gas furnaces A modulating gas furnace regulates the gas that is burned to maintain thermostat temperatures.

Then cooled flue gas is vented out of the flue system.

. After the gas enters your furnace from a storage tank LPG or the local gas supply network natural gas the burner lights it. The condensing furnaces primary heat exchanger operates similarly to a conventional unit removing the bulk of the heat from the flue gases generated by the gas burner. Todays condensing furnaces use a secondary heat exchanger.

Ventless Condenser Dryer - How It Works. Here more heat is extracted resulting in the gases that are cooled to the. That water vapor is next sent to the second heat exchanger where it is condensed and turned into a liquid.

Exhaust from the combustion is piped out of the furnace through the vent and exits the home via an exhaust pipe. A pipe connects the furnace to a natural gas pipe network and the burner lights the gas after it enters. Here are the steps in the drying process.

The secondary heat exchanger removes more heat from the combustion gases which then condense to produce water vapor. The function of a condensing furnace is similar to a regular fuel-based forced-air furnace. A condensing boiler takes water from the pressure supply mains.

Contact Allbritten for Furnace Maintenance. A condensing gas furnace combats the issue of wasted energy through the use of a second heat exchanger. Gas burners deliver heat into the first heat exchanger and the combustion process leaves a byproduct of hot water vapor.

The water is heated in the heat exchanger until it reaches the correct temperature. Cold air from your house enters the furnace where the burning gas warms it within the heat exchanger. How does a furnace heat my home.

In condensing furnaces there is a secondary heat exchanger made up of small tubes that receive the exhaust gases once they have gone through the primary heat exchanger. The heating cycle begins with the thermostat which detects when temperatures drop inside your home. Condensing furnaces These units use a heat exchanger to heat the cold air from the condensed exhaust gases.

Gas burners deliver heat into the first heat exchanger and the combustion process leaves a byproduct of hot water vapor. When a gas turns into a liquid it releases heat. The thermostat activates the furnace.

At the beginning of the heating process a condensing furnace works similar to a traditional furnace. A condensing boiler takes water from the pressure supply mains. At the beginning of the heating process a condensing furnace works similar to a traditional furnace.

This makes a condensing boiler a better option than a combi boiler especially for a large home. Click to see full answer Herein what is a condensing furnace. At the beginning of the heating process a condensing furnace works similar to a traditional furnace.

Exhaust from the combustion is piped out of the furnace through the vent and exits the home via an exhaust pipe. In this episode of Repair and Replace Vance explains how a gas furnace works. The thermostat activates the furnace.

When a gas turns into a liquid it releases heat. Then you pump it to the hot water tank where it can stay hot for some time until you need it. Process air heated wet enters the condenser is cooled releasing moisture.

Then you pump it to the hot water tank where it can stay hot for some time until you need it. And it has a gas burner with electronic ignition although condensing furnaces may have more electronic. Process air heated enters drum to absorb moisture and dry load.

Ambient air inside the unit is heated by a heating element. Well in a condensing gas furnace there is more than one heat exchanger. These furnaces use two.

Gas burners deliver heat into the first heat exchanger and the combustion process leaves a byproduct of hot water vapor. This is why units produced today can reach staggering efficiency levels nearly 100 AFUE. A pipe connects the furnace to a natural gas pipe network and the burner lights the gas after it enters.

This episode also covers AFUE furnace effic.
