Passive Solar Heating Works Even In The Winter

by Ryan McCall

Unfortunately for those of us who don't live in Southern California, the price of keeping our homes warm during the winter can be enormous. It can easily become a waste of power and savings. Going green in home heating can be effective in saving you money and helping out the environment- so why not consider passive solar heating when you're looking for alternative home heating options?

Even on the coldest winter days, the sun's heat can be significant. It's only the shortness of the days that keeps the snows from melting. What if you could harness that heating power, even for the short time you get it, without making huge changes to the structure of your home?

Enter the Trombe wall. It's a wall of material used for thermal mass (concrete or stone, for example) to store the heat of the day and release it slowly through the day and night. It's insulated on the outside by a pane of glass and an airspace to prevent heat loss to outside at night. Above the glass is a shade that allows direct exposure to the low winter sun, but shades the glass from the prolonged heat of the high summer sun, helping to keep summer cooling bills low as well.

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.

Ideas that circulate in the mainstream today do work, but people have been looking for money saving opportunities for a long time now. It's due now to the increase in environmental consciousness and rise in heating costs that is leading people to look to the solutions of yesteryear, such as passive solar heating, that were used effectively by our ancestors to save resources, to use as solutions to help save the world.

Our winter heating costs can be astronomical. Who doesn't want to save energy and money? You get the cachet of energy efficiency in these green-conscious times and you save a little extra money to use however you want. One thing people seldom consider when it comes to alternative home heating is the effect of passive solar heating. Enter the Trombe wall. It's a wall of material used for thermal mass (concrete or stone, for example) to store the heat of the day and release it slowly through the day and night.
