A fireplace heat exchanger works by drawing in cool air from the home and heating the air before discharging it into the home as hot air. There are two different ways to upgrade an open fireplace to use heat exchangers.Know More
Fireplaces vary as far as efficiency, but most are in the minus 20 percent to plus 10 to 20 percent. This means most of the heat is going up the chimney, instead of into the home.
The tubular grate type is made up of a series of steel tubes that are curved to go around or behind the fire and then exit out of the top. A blower fan is used to draw in cool air from the bottom and blow hot air out the top into the home. It is important when buying these types that the steel tubes be high-quality and able to handle the high temperature and corrosive effects of a fire. This type of upgrade can be done for less than $1,000. The cost is usually around $400 to $500 for a quality-made product that lasts.
One can also buy inserts which are basically metal boxes that fit into existing fireplaces. The inserts have heat exchange chambers built into them and usually have glass doors so the fireplace does not pull in cool air, which would force the heat up the chimney, according to HowStuffWorks. These types are a lot more expensive and require a steel flume, which could mean having to install a new flume. A person can expect to spend thousands if going with the insert.Learn more about Heating & Cooling
Water to air heat exchangers can be purchased on the Internet from eBay and Alternative Heating & Supplies. The price usually depends on the size of the heat exchanger.Full Answer >
An air exchanger is a ventilation and climate control system that swaps the air, inside a building with fresh air from outside. It provides fresh air and also helps in saving energy by reducing heat and cooling requirements. It is added to the duct work of tightly built houses.Full Answer >
An air conditioner coil is the part that turns a liquid chemical such as Freon into a gas and absorbs heat while creating cool air. The coil functions as a heat exchanger, because it draws out heat and creates the cool air that blows out of the air conditioner.Full Answer >
To install a heat exchanger, you need a new heat exchanger, wrench, screwdriver, hardware, pen and paper. Make sure that the power is off at the main breaker before beginning the installation process.Full Answer >
