For space heating applications, vertical collectors perform very well, and for year
long domestic water heating applications a steeply tilted collector can provide good year round performance if sized correctly.
Heat recovery from exhaust air could satisfy virtually
all domestic water heating demands.
(C) to produce no net emissions of greenhouse gases in space heating, cooling,
domestic water heating, lighting, and appliances; and
This is an unusually high Solar Fraction for
a domestic water heating system.
The system is equipped with fuel cells that generate electricity (5 kW) for the home, and is configured to recover the heat produced during power generation for
domestic water heating.
