| SOLAR SPACE HEATING/COOLING |
Solar hot water systems can be custom engineered to provide heating for many homes. While systems are ideally planned during new construction, systems can be designed to integrate into a home's existing heating system. In the case of traditional forced-air heating, radiant coils can be placed in ductwork allowing supplemental heating as air is forced over hot coils. In radiant heating applications, solar can provide a primary energy source as solar heated water is circulated through the radiant tubing under floors or elsewhere.
Solar almost always requires a backup energy source for heating applications. In fact, in many instances solar is a secondary energy source for heating. Forced-air heating systems, for instance, are generally designed to provide around 20% of the energy required for home heating. System design and cost are very case specific. |

Solar Air Conditioning |
|
New technology is becoming readily available to allow residential scale solar cooling. Product availability is expected in early 2009. This technology will allow absorption chillers to provide chilled air to the home. Solar air conditioning systems in conjunction with solar heating systems will allow for year-round use of solar collectors, making both investments more reasonable
