Vacuum tube collectors

Reference: C.1.1

LEME Mitigation

Produce hot water from solar energy for sanitary or industrial uses

When domestic hot water is needed (hotels, hospitals, private houses)

International certification of panels for energy saving (test by certified bodies with EN norms)

Estimated pay back time short term : 2-4 years, medium term: 4-6 years, long term : 6-8 years (*)

Medium term

Install solar water heaters . Replace fuel or electricity ; Energy saving : 800 kWh /m2/year. Evacuated tube collectors offer temperatures of hot water appreciably higher than flat plate collectors, which have however a better global efficiency.
