Solar Heating For Your Home: Active vs. Passive Systems

You might be searching for a solar heating system. If you are, then you will have many choices. For example, you will need to choose between passive systems and active systems.

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. A Passive Solar Heating System can lower your current heating costs, or even replace your home's current heating system.

What are the most important parts of Passive Solar Heating System?
Windows are the heart of Passive Solar Heating Systems. The windows' function is to increase how much heat and sunlight a home can store during the daytime. Usually the windows are made from a special type of glass that can absorb a significant amount of heat, and then retain that heat for a significant timeframe.

In addition to the windows, trombes are also important in Solar Heating Systems. A trombe is a special variety of wall. A piece of glass sits in the walls' front. That creates a space between the wall and glass, for collecting heat. To increase the heat-absorption of the concrete walls, one could also paint them black. That will attract more heat, creating the same effect as wearing a black shirt on a summer day in the desert.

What are the advantages of Passive Solar Heating Systems?
Typically, this is the right choice if you are selecting a solar heating system for a new building. A Passive Solar Heating System is founded on issues such as the quantity of insulation in a building, the location of a house's windows, the position of the building, and so on. These factors can be difficult to alter in homes that are not new. That could create several logistical problems and make the project quite pricey.

What is an Active Solar Heating System?
Such systems involve stockpiling and storing heat from solar energy. Various objects such as fans distribute the heat that has been collected. The most common type of heat collector from solar energy is silicon solar cells. Usually the cells are positioned on solar panels, which themselves are usually located on the roof of a home.


There are two main types. The difference is in the material that collects and transfers the solar collector's heat. Typically, a liquid or gas is the material. A liquid-based system frequently involves antifreeze or water to collect and transfer the heat. Meanwhile, an air-based system typically includes air room heaters or transpired air collectors.

How much power can you get from Active Solar Heating Systems?
Typically, the objective of such systems is to heat a maximum exceeding 75% of a building's interior. If a home produces excess solar energy, then a homeowner can sell the excess energy back to her or his regional utility company. Additionally, you should also consider heating both water and air in your home. That will allow your Active Solar Heating System to operate during the whole year.

The above information will help you to choose between Active and Passive Solar Heating Systems.
