Earlier this month we presented at the monthly meeting of the Western Massachusetts Green Consortium on the topic of solar hot water. In addition reviewing how the technology works, incentives, data-monitoring, and best practices. We also discussed how heat pump hot water heaters and PV inter-relate. In point of fact, we do not always recommend solar hot water for our clients. Occasionally heat pump water heaters make more sense. Sometimes, from an economics stand-point, making no change to the building's current hot water system makes sense. With all the variables one thing remains constant. Solar hot water is the best way to reduce our carbon foot-print. If an additional 3% of homes installed solar hot water, we would annually eliminate 43,500 tons of carbon dioxide from entering our atmosphere.
