When it comes to heating costs, most of us are not lucky enough to live in a temperate area with a constant year-round climate, and instead have to contend with winter heating bills that can be exceptionally high. When evaluating alternative home heating, an option that is often overlooked is passive solar heating. You not only save money, but energy as well.
Even on those truly frigid days in the dead of winter, the sun still emits a noticeable amount of heat. The only factor that precludes the accumulated snow from melting is the long night and short daylight period. Wouldn’t it be nice if you could use the sun’s heat when it’s available without needing to significantly modify your house?
For passive solar heating in a home, two elements must be present: a transparent southern exposure that allows the sun’s energy to enter the home, and a material that will absorb heat to be released slowly into the home.
Here is where the Trombe wall comes in. This wall is made of a thermal mass (such as concrete or stone) that can store the heat built up during the day, and then release it slowly throughout both the night and day. On the outside the wall is insulated by a glass pane and an airspace, thus preventing the loss of heat to the outside during the night. A shade rests above the glass that allows direct light exposure during low winter sun, but acts as a protection during prolonged high summer sun heat, this dual action helps keep cooling bills in the summer low also.
It is also possible to use a waterfall instead of masonry which will deliver heat more quickly. This is because heat is transferred much more quickly because of the convection currents in the water.
Many of us are interested in pursuing more energy efficient heating alternatives such as passive solar heating. Whatever alternative you choose the cost of installation may be expensive. Whether you are seeking a custom designed home or renovating an existing structure you have options. One advantage of passive solar heating is that once installed continued use expenses are nominal.
Even though it became popular in homes built in the 1960′s, the idea behind the Trombe wall actually originated in the 19th century. In shopping for that new, energy efficient home, you should keep in mind that you can still go green by using past, proven design techniques.
The commonly presented traditional views are viable, but we have all been searching for a long time for ways to economize. Finally nowadays, we have become more ecologically aware and, given the high prices of our usual heat sources, we have begun to think about clever answers found by our forefathers, such as passive solar heating. That allows us to preserve precious, dwindling resources and utilize them alternatively in our struggle to save our beleaguered planet.
Two important ideas to consider when it comes to alternative home heating is the use of passive solar heating and Trombe walls.
