That makes the choice purely about household size and draw pattern. A two- to three-person household rarely exhausts 80 gallons of preheated water in a day, and the smaller tank loses less standby heat overnight. Four or more people, or a household with a soaking tub and back-to-back showers, wants the 120.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStorage: 80 gallon · three TR-20 collectors\u003c\/li\u003e\n\u003cli\u003eMaximum collector area: 96 ft²\u003c\/li\u003e\n\u003cli\u003eMaximum power input: 195W (pump and controls)\u003c\/li\u003e\n\u003cli\u003eDimensions: 95 in H × 32 in W\u003c\/li\u003e\n\u003cli\u003ePotable plumbing diameter: 3\/4 in\u003c\/li\u003e\n\u003cli\u003eDrainback freeze protection\u003c\/li\u003e\n\u003cli\u003eComplete pre-engineered system: collectors, storage, heat exchanger, controls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eStandalone Or Preheat\u003c\/h2\u003e\u003cp\u003eThis size can serve as a standalone system for a small household in a sunny climate, or as a preheater ahead of an existing water heater. The preheat configuration is the safer choice almost everywhere — you get the savings on sunny days and guaranteed hot water on the fourth cloudy one.\u003c\/p\u003e\u003ch2\u003eThe Off-Grid Case\u003c\/h2\u003e\u003cp\u003eOn an off-grid property this is the highest-value single purchase after the array itself. Electric water heating is the largest load most off-grid systems face, and moving it to thermal collectors frees enormous battery capacity for everything else — often more cheaply than adding the equivalent kilowatt-hours of storage.\u003c\/p\u003e\u003ch2\u003eTwo Ordering Notes\u003c\/h2\u003e\u003cp\u003eProfessional installation is required for warranty coverage.
