What kind of heating system can I use?

SIP homes require no special heating system. Forced air, electric, solar, radiant and wood burning systems are all suitable, though some are more appropriate than others for a specific home design. Keep in mind that central air conditioning requires ductwork and is therefore most compatible with forced-air heating systems. Because of the home's tight construction, the fireplaces, wood burners, furnaces and any other combustion appliances should be supplied with an outside source of combustion air. No matter what type of system you choose, the home's inherent energy efficiency means you won't need as big a unit as you would with a typical conventionally framed building of equal size.
