Radiant & Hydronics

RSS

A hydronic system is 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. The system is designed using primary/secondary piping.

The hydronic system shown above was created to connect three gas-fired, cast-iron boilers to a low-temperature distribution system that supplies 12,000 ft. of 3/4 in. PEX tubing embedded in the floor slab.The installer spends several frustrating hours attempting to get the air out of the system. He finally gets it purged to the point that the distribution circulator is at least moving some water through the floor-heating circuits.

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.

A panel of solar industry judges chose Free Hot Water for its innovative and cost-effective design of a solar hydronic heating, hot water and photovoltaic system that was shown to be cost-competitive with a natural gas system.

The Propane Education and Research Council recently released seven new fact sheets for using propane in the residential market.

Organizations, businesses and residents are encouraged to donate new and gently used tools, as well as cabinets, sinks,building materials and appliances, to the Sonnhalter Tool Drive to benefit Habitat for Humanity's cause of eliminating housing.

An installer is asked to provide a system that supplies two zones of fin-tube baseboard and two zones of floor heating. The system also supplies domestic water heating. He selects a mod/con boiler because it’s lighter than a conventional boiler.

Alkalinity in steam-generating boilers is a problem because under heat the alkalinity breaks down to carbon dioxide, which passes with the steam.
