A flat-plate thermal collector converts 50–70% of it into heat. If the end use is heat, the thermal path is two to three times more efficient per square foot of roof. Water heating is typically the second-largest energy line in a home, which is why this system attacks it directly.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStorage: 120 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: 97 in H × 34 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 system: collectors, storage, heat exchanger and controls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDrainback Is The Right Freeze Protection\u003c\/h2\u003e\u003cp\u003eWhen the pump stops, the collector fluid drains back into the tank by gravity — leaving nothing in the collector to freeze. Glycol systems achieve the same end but require fluid testing and periodic replacement, and glycol degrades if it stagnates hot. Drainback has no consumable and no maintenance schedule, which is why it survives in cold climates where glycol systems get abandoned.\u003c\/p\u003e\u003ch2\u003eIt Preheats, It Does Not Replace\u003c\/h2\u003e\u003cp\u003eThis system is designed as an add-on ahead of your existing water heater, preheating incoming supply so the primary unit does far less work. You keep guaranteed hot water on a cloudy week and cut the energy bill on every other one.\u003c\/p\u003e\u003ch2\u003eTwo Ordering Notes\u003c\/h2\u003e\u003cp\u003eProfessional installation is required to maintain warranty coverage — plumbing, roof penetrations and a potable heat exchanger are licensed work. And this system ships to a freight terminal rather than to a residence. Confirm your nearest terminal and arrange pickup or final-mile delivery before ordering.\u003c\/p\u003e","brand":"SunEarth","offers":[{"title":"Default Title","offer_id":48233633218725,"sku":"1672011","price":4769.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0454\/1916\/7909\/files\/Cascade_2___65714.1775065446.png?v=1788728783","url":"https:\/\/www.urbansupplyinc.com\/products\/sunearth-cascade-2-solar-water-heating-system-120-gallon-w-3-tr-20","provider":"Urban Supply Incorporated","version":"1.0","type":"link"}
