Met with the contractor last week. Our bathrooms are at the other end of the house from the water heater (electric). It takes a long time to get hot water to them as I watch gallons of clean water go down the drain. He will also install a recirc line so that hot water will be available instantly. The savings on the water bill will probably eventually pay for it. All approx $5,300, installed:
We are pleased to offer a closed-loop drainback type solar water heating system for $5,300, installed, capable of producing an average of around 75 GPD of 120 degree F hot water. The system includes: 1. 80 gal integral exchanger HW storage tank w/ a 10-gallon drainback tank located in your laundry room 2. One 4’ x 10’ solar collector roof-mounted with stainless steel and aluminum hardware 3. Bronze circulating pumps, differential temperature controller, anti-scald valve, sensors, copper and PEX piping 4. Dial temperature thermometers in circulating loop return line and HW outlet line 5. Recirculating line and timer-controlled pump from far end of house back to solar tank 6. Documentation and familiarization 7. Rearrangement of your laundry room and tie-in to your HW tank I expect this solar HW system to repay your investment in about 4-5 years (with tax credit factored in) and have a lifetime of 20 - 30 years. We will provide invoice documentation showing it being in service in 2008 for the 30% federal tax credit.
