A radiant heating system was chosen to complement the HVAC system. During the evening hours when heating may be required, the system makes use of excess hot water produced by our home's solar thermal hot water system to heat the house. The HVAC heating unit will only come on if the radiant system fails to maintain the target temperature, thereby reducing energy consumption. Solar thermal systems have energy efficiencies in the 50 to 60 percent range, much higher than the 10 to 15 percent efficiencies of typical solar photovoltaic systems.

After extensive study and numerous heat load calculations, our team chose a thirteen- linear foot floor heating system produced by Runtal North America Incorporated.
