Thermal storage is an integral part of most hydronic systems that have renewable energy heat sources. Systems with solar thermal collectors or biomass boilers are prime examples.
Last month, we covered the concept of combining heat pumps with hydronic distribution systems. We also discussed the specifics of an air-to-water heat pump supplying multiple zones of radiant panel heating.
The RainCycle from Watts is a commerical rainwater harvesting system that captures, stores, pumps and treats rainwater for use in irrigation, toilets, washing and other applications.
With nearly all government-related energy programs focused on carbon reduction, fossil fuels are increasingly viewed as the past, somewhat resentfully as the present and highly unlikely as the future.
