Wasted energyFindings/Observations

Saved $212 by getting increasing thermostat setting during winter

Eliminated the room electric heaters Some savings might have come from improving

insulation in the attic The payback from replacing the existing water heater

with tankless water heater is in excess of 20 years 2kW solar panel payback is in excess of 10 years Parasitic/scavenging loads cost $0.20 – 0.50 per night.

Is it worth saving this money and at what cost?
