Nationwide Home Solar Power Contractors and Information
Most homes use some type of active thermal heating system. By far the most prevalent are gas furnaces and boilers. Furnaces heat air directly, while boilers heat water for space heating via radiators, baseboard radiators, radiant floors or air. Other burgeoning types of thermal space heating are active solar heating systems and geothermal heat pumps.
The traditional forms of thermal heating - furnaces and boilers - are by far the least efficient. Even with newer and more efficient models available (a considerable upgrade indeed), they cannot compete in energy efficiency with low-power, low-maintenance options like solar and geothermal heaters. Yet the classic models tend to be the most inexpensive up front, although energy savings and durability will over time make the renewable options more economically rewarding.
So far, we've described the types of active thermal heating systems by their driving force - either gas, solar or geothermal. Interwoven within and throughout those categories are several other types of thermal heating systems, such as absorption heat pumps, which are unique in their own right but can be powered by any of the above sources. And of course, there is radiant heating, which can be electric or thermally driven. Below, you will find informative write-ups on the many different ways to actively heat your home using thermal energy, including potential deciding factors like cost, climate, and energy consumption.
Flat-plate collectors are actually quite simple. They consist of an insulated metal box covered with a glass or plastic cover called glazing. Within the box, is a dark-colored absorber plate that is made out of a metal heat conductor and painted black to… Read more »
Flat-plate air collectors are simpler than liquid collectors and are used for space heating. Heat evaporates from air faster than liquid, making air collectors less efficient than the liquid models. Air collectors work fine for smaller applications, but p… Read more »
Solar thermal space heating can be either an active or passive process. In this article, we are going to focus on the active form of liquid based space heating. In passive systems liquid, such as water, is heated in barrels by sunlight absorbed by solar g… Read more »

I am very happy that I chose to work with this company. They did a great job, and just as important, they were nice people. They were very accommodating of my requests. Mid-project, I decided to change the location of the panels, and they happily adjusted. The changes were addressed right away and without any problems. Great work. A fine company.
The work is extemely well done & on time. Very courteous & accomadating. Cleaned up every day. They did such a beautiful job building an 800 SQFT addition to our home, you would think it had always been part of the original home.
