Will replacing the heat exchanger prolong the life of your furnace?
The heat exchanger in a furnace is the primary component in a furnace. That said, their are circuit boards, motors and other components that can also fail regardless of the age of the heat exchanger. In my opinion, if you can afford to replace the furnace, you would be much better off. The cost of the heat exchanger with labor is probably not too much less than replacing the entire furnace. ...
What are other critical parts of a high efficiency furnace exclude the heat exchanger?
All the parts are critical, each part depends on the other part to operate efficiently and safely. ...
How do you plumb a water line to a coal furnace to preheat the water prior to going into a electric hot water heater?
Is the furnace a hydroponic system? If it is you only need to get a heat exchanger (As you don't want the water to your heater flowing through the furnace) and plumb it as another zone in your house. If not you need to find a device for heating water that fits your furnace. and plumb the heat exchanger to that. I believe an heat exchanger is required by code in either case. ...
How do replace a heat exchanger on a furnace?
Your really are better off replacing the whole unit, there was a reason for the heat exchanger to have cracked or malfunction, ether for age or or a mechanical anomaly , you may have not addressed, as of yet. ...
What is a high efficiency furnace I should look into buying in order to keep my 5000 square foot home warm?
a high efficiency furnace is a furnace that uses less electicity and saves on heating expences. they are very useful in the winter and great to lower your central heating bills. ...

How do you convert a propane furnace to oil?
I have never heard of a way to do this without changing the whole furnace. Propane furnaces are usually thin steal walled heat exchangers with many burners. Oil Furnaces have a large burner chamber and then a small heat exchanger above it. If there is a way, you will need to change the heat exchanger and all electrical components. It may be cheaper in the end to just change the whole furnace. ...
Is it dangerous to run a gas furnace without the blower motor working?
Yes, you can melt the heat exchanger and start a fire that way
What is a gas furnace heat exchanger?
The heat exchanger is the metal wall or tubing that is heated up when the burners are ignited. The inside of the heat exchanger allows the toxic flue gases produced from the burners to exhaust out through the furnace flue. The outside of the heat exchanger is where the cold air passes over, becomes warmed, and is blown throughout the ductwork of the home. The heat exchanger is the only wall separating the toxic flue gases from the supply air. If a crack...

How To Replace Your Heat Exchanger When Its Not Performing Up To Par?
The heat exchanger is very important to the operation of your boiler or furnace system within your home. This is the part that takes the heat and disperses it into the air or water for distribution of your home. If your current heat exchanger is not performing correctly, here is a simple guide to help you install a new one on your boiler or furnace unit. Step 1. When you are planning on installing a new heat exchanger, the first thing that...

What forced air furnace qualifies for tax credit?
It's a matter of efficiency. Many makes have different models that have up to 98% efficiency. Generally, if you're replacing an older furnace ( fifteen years or more) with a new one, it will qualify. ...
What is the efficiency rating of a high efficiency furnace?
The efficiency rating is called annual fuel utilization efficiency or afue. For residential systems in the USA, the minimum is 80%. There is no standard for what is considered "high efficiency". The range of efficiencies goes up to about 96% for gas furnaces. ...
What are the risks of using a gas furnace?
The most important risk in using a gas furnace is carbon monoxide. If the heat exchanger in a gas furnace is damaged, carbon monoxide could leak into the air, causing a health hazard. A carbon monoxide detector and regular inspections would greatly reduce the risks and your worries in using a gas furnace. ...
When operating a high efficiency nat gas forced air furnace and heat pump at what cost ratio or percent of gas therms to kilowatt hours does it make more sense to use the high efficiency furnace only?
There are 3413 btu per kWh and 100,000 btu per therm of natural gas, these are constants. In order to give a correct answer the exact efficiency rating of the high efficiency furnace and the energy costs per kWh and therms would need to be known. ...
How hot does a gas fired heat exchanger get?
There are specific values for heat rise across a furnace heat exchanger given in all installation/operation manuals for all furnaces. As long as these limits are adhered to by the installer the heat exchanger will not overheat. I know this does not answer the question but there is no one blanket answer for all furnaces. Basically the more airflow through the furnace, the lower the HX temp and to determine when the airflow is correct a heat rise test is done and...
If a furnace is cycling every 15 minutes as soon as the flame goes out the fan stays on for a long period of time and as soon as the fan goes off the furnace starts up again what could be the problem?
Sounds like the burner is cycling on a limit switch. Check the temp. rise across the unit and compare with nameplate rating. Usually reduced airflow caused by plugged filter or secondary heat exchanger, (in the case of a condensing furnace). Fan motor not at rated capacity, registers closed or blocked, reducing airflow too. Restricted a/c coil, if fitted with a/c. lc ...
Why does your dad's gas flame and or pilot light go out when the side door gets closed?
I'm assuming you mean the furnace? If the pilot light keeps going out on the furnace, you probably have a rusted through or cracked heat exchanger. Unfortunately the only way to fix the problem is to replace the furnace. IM THE ONE WHO ASKED THE QUESTIONN THIS IS NOT A FURNACE IT IS A GAS HEATER THAT HE PUT IN HIS DINNING ROOM ...
Can you vent your Trane XE80 furnace out the side of the house using plastic pipe?
If it is an 80% efficient, non condensing furnace, No. The flue gases are too hot and will melt the pipe and pose a fire hazard where it passes thru the house wall. ...
