I have a tarm solo 60. IS 740 gallons of storage enough for a 2300 sq/ft home with good insulation, a 1200 sq/ft shop with infloor tubing and a forced air modine. The reason I ask is because I have two pressurized 370 gallon tanks , but I found another one that I could obtain for a reasonable cost is it worth it? That would give me 1110 gallons.
