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.

The sun's power to heat is high, even on the very cold winter days. If the days were longer during this time the sun would melt the snow. Wouldn't it be great to use the sun's power to heat your home without having to redo your home completely?

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.

It is not very easy to retrofit your home, and you would might need to do a major renovation. Custom designed homes are also expensive. Retrofitting your home for other energy efficient heating systems such as radiant heating is also expensive. However, with passive solar heating, after you pay for installation, it costs nothing to heat your home.

Consider also the fact that the concept of the Trombe wall is a 19th century invention that was popularized in the 1960's and so has been designed into a number of existing homes. So when you're looking for that new, energy efficient home, know that designs of yesteryear can still be green.

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.
