Well, lets say the evacs are 1K each, I.E. $4000 leaving $4.000 for two 80 gallon tanks with heat exchangers and some pumps, controller maybe. That seems a bit steep. You could pick up two 80 gallon Whirlpool electric water heaters at Lowes for about $750 total (don't connect electrically), an external plate exchanger for $200 or less, two circ. pumps one cast iron and one bronze and solar diff controller for $350 or so, then fill valves, expansion tank, pressure/temp gauge, pressure relief valve, other misc for $500 or less. Then just your piping and insulation and some other small misc.. so we are at $5800 including the collectors. [ Parent ]
