Burnham Hydronics
www.burnham.comThe Revolution® II cast iron boiler is designed for easy installation in condensing and non-condensing applications and features annual fuel utilization efficiencies of over 90 percent, the company says. Using a stainless steel heat recovery unit, system water is recirculated through a coiled heat ex-changer and reheated, extracting heat from the gases before they leave the home. The secondary heat exchanger, combined with a diamond pin configuration on the left-end cast iron section, makes the system even more efficient, the company says. The unit is prepiped with a primary/secondary loop to save time and simplify installation, states the manufacturer.

Rehau
www.rehau-na.comIdeal for retrofit and new construction applications, the Raupanel system is lightweight, efficient, and easy to install, the company says. Consisting of Rehau's 3/8-inch RauPEX® cross-linked polyethylene (PEXa) pipe, aluminum panels, and wood return bends, the system's 5/8-inch profile has minimal impact on overall floor height, requires less jobsite preparation and installation time, and its lighter weight eliminates the need for added structural support, the company says. Featuring an aluminum-intensive construction, the Raupanel system provides heat transfer characteristics that allow for reduced water temperatures and more efficient operation. In addition, its low thermal mass equates to quicker response times. The system provides a method of installing radiant heating over new or existing subfloors or concrete slabs. Flexible pipe spacing (6 or 8 inches on center) makes it suitable for a variety of installation applications. The system is compatible with commonly used floor coverings, the company says.

Roberts-Gordon
www.rg-inc.comThe company introduces Roberts Gordon® Ultravac™ controls for the company's CoRayVac® infrared heaters. The company says it is the first to patent true modulating infrared systems with these controls. Ultravac controls modulate the burner input rate with the outdoor air temperature to match the heating system's input to the building's heat requirement. Modulation of the burners in series occurs by varying the vacuum and adjusting gas and combustion air. The multifeature zone temperature sensor provides localized control, which improves convenience for building occupants, the company says. In addition, a PC-based software package offers heating system management from a desktop location. An optional modem for remote system management enables building owners to monitor multiple heating systems, in any location throughout the country, from their desktops, the company says.

Schwank Heaters
www.schwankheaters.comThe STS-JZ commercial-industrial infrared radiant tube heater offers quick installation, easy-access servicing, and uniform heat distribution for warehouses, industrial plants, service garages, loading docks, schools, retail stores, and other buildings, the company says. Eight firing rates range from 45,000 to 200,000 Btuh; unit lengths range from 10 to 70 feet long. The company offers a 10-year warranty on the Whisper Quiet burner cup and heat exchanger tubes, plus a three-year warranty on all other parts. The heater distributes heat uniformly because of newly developed webbed hanger plates that promote free passage of entrapped convection heat, resulting in higher tube temperature along the length of the tube system, the company says. The heaters save up to 10 percent in installation labor with a one-piece hanger system that doesn't require multicomponent joinery during installation, the company adds. Serviceability is assisted with a quick-latch, drop-down burner enclosure that allows access and test firing even while open, the company says. If outside air is needed due to poor combustion air quality or negative air pressure conditions, a fresh air intake collar is standard with the burner.
