Passive Solar House Design

With regard to solar water heating systems, the tech is pretty widely known at this point, so I won’t spend too much time on it — I’ll just note, though, that there are both passive solar water heating systems and active solar water heating systems available. The difference in such systems is that passive systems are designed so as to not need pumps, whereas active systems utilize electricity to provide on-demand pumping action. It’s argued by many that passive systems aren’t well suited to regions where temperatures drop below freezing regularly, due to the potential for freeze damage from stagnant water (active systems can heat the water to above freezing to avoid this).
