Geothermal Buffer Tank Options
What are the latest thoughts on buffer tank options combined with geothermal water to water when used for radiant heating? We have a large install that requires flow that exceeds the Rheem Marathon 3/4" outlets for radiant supply/return. Has anyone used the storage tanks offered by Bradford White, or similar, for a buffer tank? They appeal as the tapings are very large. The concern is the port location on such a tank, will it affect overall system performance? The price point is very attractive on these tanks. Siggy's geothermal with radiant schematics all show a buffer tank with the ports located 2 on top, 2 on bottom. the Lochinvar buffer tank matches this port layout but the pricing is in the stratosphere.
