These heat exchangers can also be used as a stand alone heat source by simply attaching a fan or squirrel cage to one side of the unit.
They can be installed in either the hot air side or the cold air return of a furnace. Please note that if installed in the cold air return you will need to install a 3 way zone valve in order for the fan to operate properly.

Water to Air heat exchangers, often called duct coils or furnace radiators, are used for installing into forced air furnace to provide heat from hot water. They are usually installed into the cold air side of the furnace if that is the best option. They work in much the same way as the central air conditioning unit.
The following things should be taken into consideration when installing a duct coil. (1) Size the coil so that the fins take up the maximum amount of the plenum as possible. (2) Securely fasten the unit so that it doesn't rattle. (3) Make sure there are no foreign objects are touching the fins or the tubes. (4) Duct tape any air leaks.(5) Do not bend the fins. If you do, straighten them as best you can. A tool called a "Rake" is available for straightening the fins. (6) If you are going to run your outside heat in the summer install a bypass valve. (7) A duct coil installation kit makes installing the heat exchanger easier.
