This system is over 30 years old and part of Arcata's pilot program for [[renewable energy]] systems. It had a slow leak from both of the dribble valves which are necessary for an open looped system. The advantage of an open looped system is added efficiency from not having a heat exchanger. The old valves were replaced after draining the collectors into a bucket from the drain outlet shown in the next picture. After being drained we replaced the dribble valves with minimum leakage and the problem was resolved.\n\n== System overview ==\n\n* 80 gallon storage tank\n* 50 gallon gas back up\n* Open loop system\n* Energy produced: 50,000 BTUs per day\n* Cost: Undetermined\n* Efficiency: 85%\n\n{{Page data\n| keywords = dribble valves, efficiency, heat exchanger, open looped system, renewable energy systems, repair, Solar hot water heater, storage tank, 50 gallon gas back up, 80 gallon storage tank\n| sdg = SDG06 Clean water and sanitation, SDG07 Affordable and clean energy, SDG09 Industry innovation and infrastructure, SDG12 Responsible consumption and production\n| published = 2009\n| license = CC-BY-SA-3.0\n| language = en\n}}\n\n[[Category:Solar]]\n[[Category:Repair]]"}
