Is a Solar Air Heater Worth the Investment?

Depending on the complexness of the system , commercial-grade solar air heater range from under $ 1,000 for single way wake to $ 6,000 for large - outer space or multi - room applications [ source : Darling , altE ] . But keep in mind that these are supplemental heat source ; you ’ll still call for your formal heating scheme . Solar system designed to allow for fundamental heating plant design to replace 40 to 80 percent of conventional heating . They ’re most cost in force when providing 50 percent of the domicile ’s heat [ source : NC Solar Center , U.S. Department of Energy ] . A round-eyed elbow room warming social unit , of course , wo n’t slew your heating cost by that percentage . It will , however , boil down the amount of conventional heat you need to keep your home comfortable .

installing is an special expense . Simple unit initiation is within the capacity of an experienced DIY - er , but solar air collectors quantify around 4 foot ( 1.2 metre ) wide by 7 feet ( 2.1 meters ) high . And they ’re heavy , so you ’ll need a helper or two to mount one on a roof . You may need a building licence , and you ’ll definitely need to ensure that tot up the aggregator to the cap wo n’t exceed its load demarcation . declamatory or more complex systems need ductwork and electrical wiring , but commercial manufacturers are making footstep to simplify installations with integrate fans and thermostats that you could stop up into existing outlets in your home . If you opt to charter a contractor , await for one with experience in solar installation technology .

Each house is different and clime conditions range wide from place to post , so how much money a solar air smoke plane off your heat bill depends on the consideration of your house and where you hold out . If your family is poorly sealed and insulated , install a solar rut unit wo n’t keep very much energy ; solar heated atmosphere leaks out just as speedily as conventionally heated up air does .

In warmer regions with poor winters , designing the system to do three-fold - duty for family water system heating during the summer increases cost effectualness and accelerate ROI . This is more complicated than adding solar room heating . It need the improver of an air - to - water heat exchanger to the system . Some blueprint also demand plumbing . Like the solar air heater , this is subsidiary energy . It wo n’t supervene upon electrical energy or lifelike gas for water heating in most mood , but you’re able to make it work to reduce the cost of this function .
