Title: Passive solar D. H. W. performance with lower costs in freezing climates

Abstract

Simple, freeze-protected, passive solar domestic hot water (SDHW) systems for colder regions of the world are possible without sacrificing system performance or complicating the installation. The use of pumps, controls and solenoid valves result in high parasitic energy consumption. Indirect thermosiphon systems delivered performance comparable to indirect active systems operated under identical conditions when parasitic energy was considered. Standard hot water tanks can be retrofitted with jacket-on-tank heat exchangers without reducing system efficiencies below standard commercial solar tanks. Retrofitted exchange jackets performed well under thermosiphon and active collection modes. Efficient, low-cost, built-to-code systems are possible using standard water heater tanks, retrofit exchanger jackets, and standard manifold type collectors plumbed in a closed-loop configuration.
