Home Systems: Active Vs Passive Solar Heating Systems

Are you interested in using a solar heating system? If so, then you will have several options. One of the main ones is whether to choose an active or passive system.

What are Active Solar Heating Systems?

This type of system involves harnessing and storing (in the form of heat) solar energy. It uses fans and other objects to dispense heat that has been harnessed. Solar cells constructed of silicon are the most common type of solar heat collectors. Typically, the cells are contained on solar panels, which are located on the roof of a home.

What are its main types?

There are two primary types. Their difference lies in the material that captures and moves the heat that is located in the solar collector. Usually the material is a gas or a liquid. For instance, an air-based system usually involves transpired air collectors or air room heaters. On the other hand, liquid-based systems usually involve water (or antifreeze) to capture and move heat.

How much power does it provide?

Usually the goal of such systems is to heat up to three-fourths of a home's interior. When more solar energy than a house needs is produced, the homeowner could then sell excess power back to his or her local utility company. Also, it is advisable to heat both the air and water in your home, so your system can function throughout the entire year.

What Are Passive Solar Heating Systems?

This type of system is a low-technology method of capturing solar energy. It functions by directly capturing the sun's warmth, and then retaining it within the house for the function of heating. This is mainly achieved through methods such as quality insulation and windows. This type of system can lower your current heating costs, or even replace your home's current system.

What are its components?

Windows are the primary components of such systems. The goal is to maximize the amount of sunlight and heat that one can collect during the daytime. Typically, the windows consist of a special variety of glass that absorbs as much heat as possible-and then keeps it indoors for a maximum amount of time.

Besides windows, another common component of Passive Solar Heating Systems are trombes, which are a special type of wall. There is a pane of glass in front of the wall. The mission is for the space between the glass and wall to collect heat. Another method is to paint the concrete walls black, so they will absorb sunlight more.

What are its benefits?

This is generally an ideal option when you are looking for a solar heating system for a new home. The reason is that Passive Solar Heating systems are based on factors such as the location of the windows in the home, the location of the building itself, the amount of insulation in the building, and so on. These issues can be quite challenging to change within existing homes-and especially the location of the home!

After learning the basics of Active and Passive Solar Heating Systems, it is time to determine which one is best for you.
