A buffer tank is used in heat pump and boiler hydronic systems to prevent equipment short-cycling, reduced system efficiency, and reduced equipment life due to a mismatch between the equipment output (BTUs) when operating and the system load (BTUs) at any point in time. A buffer tank “de-couples” the heat pump flow requirements from the hydronic system flow requirements.
Geo-Flo’s HCT Buffer Tanks are used with geothermal water-to-water heat pumps, air-to-water heat pumps, boilers, and other hot- and chilled-water hydronic systems requiring a buffer tank. These HCT’s feature a composite tank that will never corrode, and factory installed brass union fluid connections. The tank is insulated with a high R-value urethane foam and covered with a high-impact plastic jacket that resists scratches, dents and condensation formation.
