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.

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.

The overlooked benefit of hydronics.

Although this is a pretty simple objective, it’s not a routine installation.

An efficient hydronic system is more than just a high-performance boiler.
