Do you have a need to install water to air heat exchanger in your home or building? We have a water to air heat exchanger for sale, and we can help you find the right unit of heat exchanger according to your need. The first thing to do is to know what a water to air heat exchanger is.
A water to air heat exchanger used to be installed into a forced air furnace to function as a heat provider. It is commonly installed into the furnace’s cold air side. A heat exchanger works the same way as a central air conditioning unit does. The water to air heat exchanger affects the transfer of hot water heat through seamless copper tubes that have high density aluminum fins. The furnace fan blows through the water into the water to air heat exchanger, which in turn will heat up the air in the duct and bring heat to your home.
Water to air heat exchangers are able to be used for apartment buildings and condos, residential heating, air conditioning, hybrid systems and dehumidification.
When making a decision as to what size of water to air heat exchanger is needed, you have to measure the plenum at the top of the air conditioning coil and buy the size that is smaller than the measurement. For example, if the measurement of the plenum is 21 x 21, you should buy an exchanger measuring 20 x 20. The exchanger should be able to slip inside the duct work. The next thing to do is to install a piece of metal at a 90-degree angle by screwing it inside the duct. This should be installed on the right and left side of the duct. One piece can also be installed at the back of the duct. In doing this, the heat exchanger will be strongly held in place for long time.
The following is basic information about water to air heat exchangers:
- The water to air heat exchanger is available in various sizes depending on individual needs.
- The frame is provided on the opposite end of the outlets to cover the copper elbows. The area inside the plenum must be longer.
- The exchanger housing is manufactured using galvanized steel. The headers, on the other hand, are made of copper.
- The water to air heat exchangers should include flat front face mounting for convenient installation and to increase the plenum strength.
- The aluminum fins and copper tubing are essential parts of heat exchangers.
- Installation of copper outlets can be done with either push fit type or sweat fittings.
Here are some things to take into consideration for water to air heat exchanger installation.
- Sizing the coil is essential for the fins to take up the maximum amount of plenum.
- Fasten the unit securely to avoid rattling.
- Ensure that no foreign objects are in contact with the fins or tubes.
- Duct tape any possible air leaks.
- Never bend the fins, but if you do, you should straighten them the best you can. A special tool is available for use.
- If users intend to run outside heat, installation of a bypass valve is necessary.
- All the coils should be packed in foam during shipping in order to avoid damage.
- The use of an installation kit will make installing easier.
The water to air heat exchanger can be employed as a stand-alone heat source by attaching a fan or a squirrel cage at one side of the exchanger. Owners can choose to install it in either the hot air side or cold air return of furnace. If it is installed in the cold air return, a 3-way zone valve must be installed for proper operation of the fan.
When using the exchanger, it is crucial that the nipple on the exchanger that is nearest to the fan must be the cold water return to outdoor wood furnace. On the other hand, the top nipple that is farthest from the fan should be the hot water feed. This is of utmost importance because when the cool air enters, the bottom nipple will pre-heat the air that enters the exchanger, and as the pre-heated air exits, the top nipple will affect heating of the air. The effect is reversed if the hook-up is backwards. The exchangers can work with chilled water as well.
The newer designs of water to air heat exchangers can be installed easily by slipping the unit into the plenum and attaching it with the use of self-threading screws. Installation will not require any special tools. The unit will be easier to install because it will be attached from the front.
