VERT / GREEN
Estimate hot-water demand, orientation/shading and roof condition before choosing a system.
Solar thermal water heating
Coordinate collectors, roof, heat exchanger, storage, freeze/overheat protection and backup water heating for Canadian climate.
JAUNE / YELLOW
Year-round operation requires real freeze and overheating protection plus heat-transfer-fluid/exchanger maintenance.
ROUGE / RED
End-of-life roof, uncertain structure, unknown pressurized loop or failed freeze protection: correct/design before installation.
