Given energy concerns these days, most homes are now designed to take advantage of passive solar heating concepts. Solar thermal is a big part of this process.
How Thermal Mass Works In Your Home
Getting a little free heating can go a long way on your utility bill, particularly over the life of a structure. Passive solar heating is the methodology used to achieve this goal. It is a process wherein a home is built or upgraded in such a way as to catch and contain as much of the sunlight in the form of heat as possible. To effectively use solar for heating, thermal mass is a subject you need to understand.
Thermal mass simply refers to any material that absorbs and stores heat. In this case, we are obviously talking about material that stores the heat inherent in sunlight and disperses it at a later time once the sunlight is no longer hitting it. You may not realize it, but your home already has thermal mass producing heat. Any material exposed to the sun, furniture, floors and such, acts as thermal mass. Unfortunately, it is usually on a pretty small scale.
Often called intentional thermal mass, a passive solar home will have strategically placed...
