Panel vs. Evacuated tube cost benefits
Can any one explain the cost benefits of Evacuated Tube verses Flat Panel for Domestic Hot water only. We are proposing either 2 flat panel or 2 sets of evacuated tube and are only going for domestic hot water, The location is Midwest about 40 miles north of Chicago. I am undecided if the cost of the tube is going to outperform the flat panel and if the cost upgrade is going to pay off.
