Residential Solar Heating Retrofits

Residential Solar Heating Retrofits

Adding (retrofitting) a solar space heating system to your home is one way to combat increasing energy costs and to raise your home's market value. The two major types of solar retrofits are active systems (requiring mechanical energy and hardware such as pumps and fans to distribute heat) and passive systems (which depend on the natural circulation of a fluid for heat movement).

Sizing Residential Heating And Air Conditioning Systems

Sizing Residential Heating and Air Conditioning Systems

Older space conditioning systems (more than 10 years old) are often unreliable and much less efficient than a modern system. When it's time for a new replacement, choosing one of the correct size (heating and/or cooling output) is critical to getting the best efficiency, comfort, and lowest maintenance and operating costs over the life of the new system. Some national surveys have determined that well over half of all HVAC contractors do not size heating and cooling systems correctly.

Heating Your Home With An Active Solar Energy System

Heating Your Home with an Active Solar Energy System

Active solar heating systems consist of collectors that collect and absorb solar radiation and electric fans or pumps to transfer and distribute the solar heat in a fluid (liquid or air) from the collectors. They may have a storage system to provide heat when the sun is not shining. An active system may be more flexible than a passive system in terms of siting and installation.
