Water quality. If you haven’t spent a good deal of time thinking about it and the impact it has on your hydronic heating system, think again. In fact, it’s so critical to the performance of the system that the installation and maintenance of the system should never be done without consideration of how to maintain the water quality that keeps the system running.
Any untreated system with iron pipework is susceptible to the perils of corrosion, which can sap as much as 15% from heat-transfer rates and up to 6% from boiler efficiency rates after only three weeks. These declines are not only unexpected, but also unacceptable to building and homeowners who expect their high-efficiency equipment to consistently save them money over the long run.
