Solar Compact vs Direct Systems

How does a direct solar water heating system work?

Explaining the Competition: Direct solar water heating systems pass potable water through the thermal collector that eventually flows directly to the desired application (the faucet, the showerhead, etc.).

How to design a direct solar gain system?

During the design of direct solar gain systems, it is sufficient to choose the aforementioned elements, the thermal mass of the building, and the heat-gain diversification so as to guarantee maximum heat collection during solar radiation while minimizing the risk of exceeding the target temperature level of interior air.

How can direct solar gain systems improve thermal efficiency?

One of the ways of improving the effectiveness of direct solar gain systems may be to increase the thermal capacity of the elements of the envelope of rooms not covered with lining that impedes solar energy absorption (e.g., floor carpeting) or link them with the central heat distribution system.

What is the difference between direct and indirect heat storage systems?

Traditionally, indirect systems are more successful nationwide than direct systems because of their resistance to cold. Indirect systems circulate collected heat to a storage tank in a basement or utility area. In the winter, this is a much lower threat of heat loss than an outdoor storage option.
