Solar Air Heater Install - North Pole, Alaska 

solar air 





The install went great, and may I say the units are EVERY bit as you said, as for their quality of construction.   I was not expecting to see the quality of construction that you have!!

Several of the units had bent attachment flanges, from shipping, but were easily straightened.  It would have been much worse if not for your great packaging.  I AM TOTALY SATISFIED!  Because of the shop at a few degrees off, I will probably get a couple more to put on another wall.

I have been amazed at how much less the oil heater runs.  The shop is super insulated, but the oil usage has dropped since the install. 

It is an absolute that I am changing the design of the house that will be built next to the shop, to accommodate 2 large units, aprox 20 feet, of panels.  

I am at work now,  I will talk again later.  Regards  Tony

Solar Air Heater Model SAS1548 Shutters  

An evolution in design, Solar Air Systems breakthrough patented passive solar air heating shutter system looks just like a vertical house window shutter – but does something no other window shutter can do - generates heat!

Use the power of the sun to help generate free heat and reduce your heating bills with solar heating technology. The unique Solar Air Heater shutters passive solar heater is capable of reducing heating bills by as much as 45% per room. This breakthrough shutter design, passive solar heating shutter application generates clean, renewable heat without changing the look of you home.  It's an easy, affordable and a cost effective way to bring passive solar heating into your home, apartment, office or building to reduce heating bills.


When installed side by side next to your south-facing windows (sunny side), the Solar Air Heater shutters generate free heat from the sun.  Air temperatures leaving the Solar Air Heater shutters and recalculating into your home can reach 160 degrees.


How can Solar Air Heater Shutters help reduce your monthly heating bills?


During the fall and winter the sun is low in the sky. South-facing rooms receive the majority of the sun’s direct rays. When Solar Air Heater shutters are installed along side of your existing windows, these rooms have more exposure to the sun energy from outside your house.  The sun heats the inside of each shutter using the Patented energy absorbing aluminum core of each heating shutter surface area. As your inside room air travels through the shutters heated insert cores,  it is heated up to 160 degrees and exits the top to re-circulate into your room as free heat.


That means you can turn your thermostat down during a sunny day and let the Solar Air Heater shutters help keep temperatures up. Even if no one is home during the day, the Solar Air Heater shutters will provide heat to your home for free. And when you return home your furnace won’t have to work as hard to raise the temperature to the level you desire. The less your furnace works means there’s money being saved on home heating bills.


Not only do Solar Air Heater shutters generate free solar heat, but they are aesthetically appealing. Solar Air Heater shutters look like existing house shutters and are the smart, simple way to bring solar heat into your home while lowering your heating bills and reduce dependence on fossil fuels.

Solar Air Heater True match airflow based on panel temperature ensures maximum efficiency.


Airflow matching is critical when designing a solar air heater. Our controller uses a thermistor to constantly monitor inside panel temperature while adjusting fan speed (RPM).

heater fan 

We designed the solar air heater true match airflow system back in 2009.


Our solar air heater programmable circuit design enables preset temperature settings. Multiple temperature set way points enable the fan to either ramp up or down depending on your inside panel temperature.

Examples: If a cloud passes between the sun and the panel, the temperature drops. The fan will automatically ramp down. If it’s a hazy day, one of the preset temperatures will control CFM output to accommodate the panel temperature. A bright sunny day, the fan will ramp up to full CFM output.

Solar Air Heater
Adding a solar air heater system to your home is one way to offset increasing energy costs. A Solar air heater works by circulating air from inside your home through the system mounted on the exterior wall. The room air can gain up to 30 - 40 degrees before being vented back into the room. Our module system design allows a multiple array to accommodate maximum outside surface area. Two 4-5" holes are required to be drilled through the exterior wall to accommodate the intake and exhaust ducts. These solar air heaters are used to supplement an existing home heating system and can save up to 30% to 40% on home heating costs annually.

 Older Style Solar Air Heaters

  • Most solar air heaters work on the same principle as a greenhouse wherein sunlight is converted to heat within a glass or plastic covered enclosure. The heat is then trapped in the enclosure by the glass or plastic. Solar heating is an economical way for persons to augment the heating of homes and other buildings. The devices can be economical to build or buy and energy from the sun is free. Still, older style devices are not as efficient as homeowners or other building owners would like. The reason for this, at least in part, is because cold incoming air is allowed to mix with the heated air in the solar air heater. Such mixing decreases the average temperature of the air in the heater and, thus, reduces the overall efficiency of the heater.


  • Solar air heaters have tried to increase efficiency by one or more of, for example, increasing the size of the heater, increasing the surface area for radiant energy absorbance within the heater without increasing external surface area or increasing the layers of clear, transparent or translucent material covering the device. One older style solar air heater is described in the book "Solar Air Heater" (Ray Wolf, Rodale Plans, 1981). This solar air heater tries to increase efficiency by increasing the surface area of the heater. This heater is described as a 4 foot by 8 foot enclosed space covered with translucent fiberglass cloth where cold room air is forced into the device at the base, heated by solar energy and then expelled from outlets at the top back into the room. The enclosure is one large area where cold air can mix with warmer air thereby bringing down the average temperature of the air within the device and, thus, lessening the temperature of the air being expelled back into the room. Additionally, the device is designed to permanently mount on an external wall of the building. Many homes may not have such an expanse of wall space conveniently located for both best sun exposure and best room air exchange.


  • Our 1500 Series relates to a solar air heater wherein the enclosed space within the device housing is divided into several essentially isolated sections by a partition. The partition(s) of the 1500 Series solar air heaters are parallel to each other and to the top and bottom panels of the enclosure. The partition(s) of the enclosure contact the side panels perpendicularly and contact the front and back panels at a non-perpendicular angle. Furthermore, the partitions of the 1500 Series comprise a plurality of channels allowing adjacent sections to be in fluid communication with each other. The channels are small enough in diameter to prevent any significant back flow of air. This design not only solves the older style solar air heater problem of incoming cold air mixing with the heated air within the heater but also provides the unsuspected benefit of increased heater efficiency by heating the air in a step-wise manner. This step-wise heating of the air, where the heated air of one section provides the starting air of the next adjacent section, results in a greater temperature gain as compared to a similar sized device not incorporating the step-wise heating technology of the 1500 Series. Additionally, the partitions of the solar heater of the 1500 Series also aid in the heating of the air. The partitions of the 1500 Series, in one embodiment, are made of materials and or colors which are known to absorb solar radiant energy thereby proving additional heating of the air as it passes through the channels of the partitions.


Return on Investment:

The return on investment (ROI) for a solar air heater purchase is relatively short. Your energy savings will equal the cost to buy and install the system in 2 to 4 years.  Unlike conventional heating systems, solar air heaters require very little maintenance and they keep working decades beyond the initial cost. "A greener energy solution for the world" is our company slogan and purchasing our solar air heater modules will decrease Propane, Electricity, Natural Gas, and Oil consumption. The energy source to power your solar air heater module system is sunlight, and it’s free from day one. 


Installation is inexpensive and easy:


Our solar air heater systems design is simple and within the capacity of any DIY-er. Other solar air heaters measure between 4 to 5 feet wide by 7 to 8 feet high. They're heavy, so you'll need a helper or two to mount one on a roof or side of your dwelling adding a considerable installation cost. The freight can easily run between, $300.00 to $600.00 per panel.

Our Solar Air Heater 1500 Series Modules have been specifically designed to be both easy to install (1 person installation) and easy to remove in the event of relocating. Easy under the arm handling makes this a safe, and easy installation. Shipping and handling of each Module is between 22.00 and 35.00 per module, saving hundreds of dollars when calculation your initial cost over other available solar air heater systems.


How it’s made:


All of the materials used in the fabrication of our Solar Air Heater 1500 series module are made in the United States of America.  The thermal absorbing insert are protected by a United States Patent. The proprietary design of the 1500 series manufactured by Solar Air Systems is manufactured under a license agreement.

The Patented Solar Air Heater Technology includes a built in angle over 22 degrees when mounted to the side of a structure. The advantage of this built in angle over all other solar air heaters will be obvious when using the NREL Solar calculator.

The U.S. Department of Energy (DOE) for renewable energy and energy efficiency research, development and deployment has a wonderful new research tool.

This research tool enables consumers to view energy savings and efficiency by geographical location including angle array.

Users can select a location and choose to use default values or their own system parameters for size, electric cost, array type, tilt angle, and azimuth angle. In addition, the PVWatts calculator can provide hourly performance data for the selected location.

You can see the efficency of our advanced "Step-wise Heating™” technology when determining solar gain angle. After your report is generated, simply change the array angle to 22.5 degrees and click on calculate. 

Compare flat plate solar air heaters to our built-in angular system! 


Solar Air Heater Technology


The 1500 Series is a module array heater assembly with step-wise heating technology™ providing heating of air in a step-wise manner.  The housing, comprising of a front panel of light-transmitting 3/16" low iron clear glass, one or more air inlets and one or more air outlets for establishing a flow path for the air to be heated, and a series of several partitions. The partitions being essentially parallel to each other creating essentially isolated sections within the housing between the partitions. Each partition has a longitudinal axis and a normal axis, the normal axis being perpendicular to the glass of the partition, each partition comprises a plurality of parallel channels permitting adjacent essentially isolated sections to be in fluid communication and said fluid communication is through each partition. The fluid communication between the adjacent essentially isolated sections and through the partitions is along a route perpendicular to the normal axis of each of the partition and perpendicular to the longitudinal axis of each partions.

The partition(s) of the enclosure contact the side panels perpendicularly and contact the front and back panels at a non-perpendicular angle. Furthermore, the partitions of the 1500 Series comprise a plurality of channels allowing adjacent sections to be in fluid communication with each other. The channels are small enough in diameter to prevent any significant back flow of air. This design not only solves the older style solar air heater problem of incoming cold air mixing with the heated air within the heater but also provides the unsuspected benefit of increased heater efficiency by heating the air in a step-wise manner. This step-wise heating of the air, where the heated air of one section provides the starting air of the next adjacent section, results in a greater temperature gain as compared to a similar sized device not incorporating the step-wise heating technology™ of the 1500 Series.
