DIY solar heating
Proper use of passive solar heating techniques can reduce energy consumption by 30% or more.
Some basic principles of passive solar heating
- In the northern hemisphere you maximize your solar capacity by orienting the house south, perpendicular to the high point of the sun on the winter solstice.
- Windows angled to receive the maximum sun
- Mass (e.g. a wall) absorbs heat from the sun and holds it
- Mass releases or "radiates" the heat at night when the temperature drops
- Mass acts a battery for heat that can be used for trapping and distributing heat
diy passive solar heatingA sun room on the south side of the house, or a "void space" will act as a regulation chamber. This room will have strategically placed south facing windows with temperature intake regulated by blinds. This void space is an area to trap heat which can be radiated throughout the house at night when the temperature drops. Windows, skylights, even chimneys allow for good air circulation so that the heat can be emptied from the chamber when it is not needed. Diy solar heating provides cool ways to reduce the energy use in your home.
Another important fact to remember for diy solar heating enthusiasts is that most heat is lost through the roof. Insulating your roof is absolutely crucial to maintaining heat in your home while skylights offer a way to release heat. What's right for you depends on your environment.
