SPACE HEATING OVERVIEW
Note: Solar space heating is complicated and while SolarRoofs.com offers the easiest to install collectors available, a qualified HVAC contractor is usually needed to design the system. SolarRoofs.com offer some prepackages systems as shown below but beyond that it does not design systems. Please have your HVAC contractor contact us if our prepackaged systems do not meet your needs. Remember, most cost effective solar option is usually solar water heating.
Because of its ThermaFin “Crystal Clear” all copper absorber, well insulated box, “double-glazed” performance and ease of installation, many homeowners and dealers use our Skyline® collectors for their space heating systems. Space heating systems are much more complicated than water heating systems. They also cost more, can be prone to over-heating and need the most energy when the least is available. That said, properly designed glycol drainback closed loop systems have performed well and have made many customers very happy.
A rough rule of thumb is that 10 to 15% of the living area in a home is required to provide 50% of the space heating in sunny winter areas like Colorado. More area is required in cloudier areas like New England and most other northern states. Naturally the more efficient a house, the less area is required. In areas like San Diego where light space heating is required, as little as 4% of the living area in a home is required to provide 50% of the space heating.
Remember, the best savings are initially gained by the conservation measures you take such as increasing insulation and reducing infiltration.
The larger the system, usually the lower the cost per square foot. Many times the actual size of a system is dictated by budget, rather than ideal performance.
Air and radiant floor heating systems are a good match for solar space heating because they usually require heat at around 100 degrees F for good performance.
We provide the system basics but you may need to seek out a good heating specialist to design the integration of the solar system with your space heating system, or use our easy to connect Chill Chaser.
We recommend at least 160 square feet of collector area to make a reasonable contribution to space heating needs but smaller systems can make a good "area" contribution.
A solar space heating system is much more sensitive to tilt and orientation than a solar water heating system. For space heating the collectors must be facing (oriented) within 15 degrees of TRUE South, and need a tilt within 10 to 15 of latitude, usually the steeper the better to face the low winter sun.We recommend a 50 degree to vertical tilt.
Note: Latitude is the elevation angle of a point above the equator.
Systems mounted on vertical South walls have had excellent results because they collect the low winter sun and usually do not over-heat in the high summer sun. Snow on the ground can increase performance by actually reflecting solar rays onto the wall-mounted collectors. The long, light weight collector Skyline® is excellent to mount on a wall or as an "awning" mount tilted off the wall.
Do not use solar with baseboard or radiator heating. The 150 to 180 degree F temperatures required for convection are much too high for the solar collectors to operate efficiently during the winter. If you have baseboard heat consider using a "Fan Convector" such as the Turbonics Chill Chaser or Myson unit. They are great for solar space heating as they have the fan, heat exchanger, thermostat and pump all in one attractive unit. The Lo-line or the Slim-line are the ones we have used in the past.
People often make the mistake of thinking the solar will "preheat" the baseboard water when the baseboard water is actually in a closed loop leaving the boiler at usually 160 F and returning at 150 F.
A solar water heater can save a lot of money by preheating the domestic water going into an oil or gas boiler and by allowing the boiler to be turned off during the summer.
A trend we have seen is to turn off the boiler in the summer and use the upper electric element of the Rheem Heat Exchanger tank for the small amount of backup required during the times the boiler can be turned off.
On a sunny cold winter day, a flat plate collector can provide from 400 to 700 BTUs per square feet of collector area. Your heat loss needs to be determined for proper sizing. An example of a typical size array is 8 collectors for 160 square feet. This array would provide the energy of about what one gallon of propane in an 80% efficient heater would produce per day.

5. Radient Slab used as storage by directly feeding solar heat into the slab after domestic water has been satisfied. Please see: Direct Solar Radiant Floor Storage.
The Silver Skyline4 Drainback system includes the basic parts you need to add solar water heating. As with other typical solar water heating kits, no fittings or tank connections are included so soldering and technical skills are required to finish these systems.
Silver Skyline4 High Value Drainback system includes:
Skyline 20-05 AIR COLLECTORS
SolarRoofs.com Exclusive Air Collectors are very light weight and comparitively easy to install.
We are currently developing the systems so balance of system components such as fans, ducts etc. will need to be purchased separately. The pictures below show some details.
SolarRoofs.com's low cost Skyline 10-05 (10 s/f, 20" x 6') and 20-05 (20 s/f, 20" x 12') Air Collectors are a new generation of light weight, easy to install air collectors that are very effective and delivering Btu's directly into the home, office or warehouse.
General Sizing Guidelines
Systems should be sized to have a minimum of 1 sq /ft. of collector area per 10 sq/ft of floor area, it can be less in warmer areas, more in very cold climates. These collectors can be custom configured with holes cut, seals and racks supplied to fit your specific needs. 4", 5", or 6" holes can be made at the center of either end and 1" by 6" air slots can be made at each corner to facilitate series air flow through multiple stacked collectors.
Always insure that fan pulls air through collector, never push air through collector(s).
Standard Color is Musket Brown (CO101), with a Free option of Dove (Medium) Gray (C109)
(Other color options are available at an extra cost)
