Zien Mechanical Contractors No. 2 is a single-family residence in Milwaukee, Wisconsin. The home has approximately 1304 square feet of conditioned space. The solar energy system consists of two independently controlled systems: one system is used for domestic hot water (DHW) preheating, the other is used for space heating and cooling. Only the DHW system is described here. The solar energy system has an array of flat-plate collectors with a gross area of 77.6 square feet. Distilled water is the transfer medium that delivers solar energy from the collector array to a conventional 120-gallon DHW tank. The distilled hot water flows through a tube-in-shell exchanger assembly normally stores the distilled water when it drains from the collector after each collecting cycle. This drain-down feature protects the collectors from freezing damage. Unheated city water is fed directly to the DHW tank, and is supplied, on demand, to the DHW load. When solar energy is insufficient to satisfy the DHW load, an electrical resistance heater in the DHW tank provides auxiliary energy for DHW. No antifreeze additive is required. (MHR)
