An installer decides to use a four-way motorized mixing valve to interface between a gas-fired, cast-iron boiler and a low-temperature radiant panel system.
A hydronic system is to be designed to supply four
panel radiators, each with its own thermostatic radiator valve, and an indirect
water heater from a gas-fired sectional cast-iron boiler.
An installer is asked to build a system to
supply both radiant floor heating and a “hydro-air” zone. All heat will be
supplied from a gas-fired cast-iron boiler.
