What are the two types of solar space heating systems?

• A. Active and passive
• B. Photovoltaic and thermal
• C. Central and distributed
• D. Mechanical and natural

Answer: (A)

Solar space heating comes in two main approaches: passive and active. Passive solar space heating uses the building’s design, materials, and airflow to collect and store heat from the sun without using pumps or fans. This relies on things like south-facing windows, concrete or brick floors and walls that absorb heat during the day and release it slowly, and well-insulated, well-sealed spaces to keep heat where it’s needed. Active solar space heating, on the other hand, uses mechanical components to collect, transfer, store, and distribute heat. Solar collectors capture heat, a fluid or air moves that heat to a storage tank, and a distribution system (such as radiant floors or ducts) spreads it through the building. The other terms listed don’t describe the standard two-type division for solar space heating—photovoltaic and thermal relate to electricity vs heat, central vs distributed refers to system layout, and mechanical vs natural isn’t the recognized pairing for this concept.
