An installer is asked to provide a relatively simple single-zone, slab-type floor heating system supplied by a geothermal water-to-water heat pump. He’s heard that a hydraulic separator is a good component in such systems.
An installer uses an unpressurized thermal storage tank for drainback protection of a solar thermal system, and carefully slopes all the collectors and collector array piping for 1/4 in. per ft. drop.
