I am installing my first solar heated / water heater this summer.
and am building my first solar collector to connect to my water heater.
I expect that the electricity that was used to heat my water with will only be needed on cloudy days.
also I intend to install a circulation pump to circulate hot water from the water heater to heat my house with this next winter.
also I will be installing a ground water cooling system this summer.
hopefully these improvements will reduce my energy footprint and save a few hundred dollars to boot.
I am not removing any of the already installed heating or cooling equipment , only adding heat exchangers , a few collectors and a better water heater that has three inch insulation vs the normal 1/2 inch insulation.
hopefully everything goes well and I wont end up soaking the attic with water from a missjudgement.
I believe that this is a start , and a good one , in the war on warming.
well not really a start , I started when I changed ALL the light bulbs in the house to the CFL bulbs , and switch them off when not in use...
