The types and configurations of heat exchangers used in liquid-type, solar-assisted domestic hot water heating systems are discussed. Failures in heat exchangers are attributed to corrosion, thermal stresses, mechanical stresses, or pressure drop in the potable water. The types and designs of the heat exchangers discussed include tube in shell, double tube in shell, tube on shell, tube on shell (separated), shell on double tube, and triple wall (tube). Other heat exchanger designs on the market include tube and fins, shell and pressure (cascade), and double shell and tube. Common sources of contamination of the heat transfer fluids include antifreeze additives, chemical additives, impurities in the plumbing networks, and decomposition products formed in the heat transfer fluid. Definitions of toxicity ratings and toxicity test reports on ethylene glycol, propylene glycol, silicone fluid, and paraffinic oil are listed.
