An installer plans to replace an outdoor wood-fired furnace with a new cordwood-gasification boiler with a rated output of 150,000 Btu/hr. The outdoor furnace is located about 100 ft. from the indoor mechanical room where the 1-in. PEX insulated underground piping joins the thermal storage tank. The installer plans to use the existing underground piping.

An installer wants to achieve hydraulic separation between three zone circulators. He also wants to have the same supply water temperature to each zone, so he pipes up what he calls a “modified primary/secondary system.”

A designer needs to connect an indirect water heater to a multiple boiler system. He selects a hydraulic separator and connects the piping of the indirect water heater on the same side as the boilers.

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.

The piping strapped to the bottom of the floor joists is supposedly part of a primary loop.

A designer needs to tie in an indirect water heater to a multiple boiler system. He selects a hydraulic separator for the project and connects the piping of the indirect water heater on the same side as the boilers.

Due to the high price of fuel oil, a contractor is hired by a building owner to install a wood-gasification boiler to supplement the oil boiler. The building’s distribution system consists of a three-zoned air handler with hot water coils.

The system was intended to supply one high-temperature heating zone, a couple of medium-temperature zones and two zones of floor heating for a garage and breezeway where antifreeze protection was needed.

Joe Wrenchturner gets a call to install solar water heating for a longtime customer. He buys some flat-plate collectors through an online source and decides to assemble the remainder of the system using hardware he installs for other hydronic systems.

An installer plans to use a geothermal heat pump to supply warm water to a multizone radiant ceiling panel system.  Having heard that radiant ceiling panels also can be used for cooling, he decides to pump chilled water through the same radiant ceiling distribution system.
