Yes
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.

IF BLOWER MOTER IS RUNNING CHECK FOR PLUGGED: FILTER BLOWER WHEEL OR MOST LIKELY (IF A 90+ FURNACE) THE SECONDARY HEAT EXCHANGER lc
depends on whether you have to pay for the wood... if the wood is free then you can't beat the costs.
Heat exchangers are not indentical to furnaces. However, they do serve a similar purpose. Both heat exchangers and furnaces serve important individual purposes. They also aee ulilitzed for different devices.

All the parts are critical, each part depends on the other part to operate efficiently and safely.
air handler
furnace highest rating is 97 % efficient for a residential model. This is known as a condensing furnace.
The fan delay is designed to allow the heat exchanger to warm up before the fan blows air into the ducts. This helps increase efficiency and prevents cool air from being circulated initially. Once the heat exchanger reaches the set temperature, the fan will turn on to distribute warm air throughout the home.
increase the efficiency of the system
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.
Yes,It depends if it is gas fired or electric.
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.
The efficiency of a Luxaire PBNU LD16N080D furnace is around 80% AFUE (Annual Fuel Utilization Efficiency), which means it converts 80% of the fuel it consumes into heat for your home. This is a standard efficiency rating for many mid-range furnaces.
Yes, you can melt the heat exchanger and start a fire that way
Its because air is forced into the furnace to increase temperature. Steve.
