Meeting the ultra low NOx requirements of California and Vermont, Therm models C 1210 ESC, C 1210 ES, C 1050 ES, and C 950 ES are condensing tankless water heaters.
Even though the first cost of hydronic equipment is usually more expensive than forced-air units, customers often remain willing to pay the premium for the constant, even temperatures a properly designed hydronic system can provide.
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently announced its new certification program for variable refrigerant flow (VRF) equipment. “It’s the first certification program for this type of equipment in the world,” said Bill Tritsis, AHRI vice president, certification.
There are several types of radiant heating systems available, including hydronic, electric, and infrared. The products described here illustrate all these types of radiant heating, including the components and accessories that are commonly associated with these systems.
The boiler header manifolds are available 1¼ and 1½ diameter and come in two, three, and four-zone units. The manufacturer’s boiler header manifolds are a prefabricated header for hot-water boilers and can be used on the supply and return.
Condensing commercial boilers — the PF-850 (850,000 Btu) and the PF-1000 (1 million Btu) — have been added to the Peerless PureFire® line of products, part of the Peerless Boilers brand.
New technology in the HVAC industry stretches past equipment breakthroughs and component enhancements. Ancillary software and communication elements are often keys to making advanced heating and cooling solutions run correctly.
While manufacturers continue to look at ways to make HVACR equipment as energy efficient as possible, just as much attention is being paid to finding ways to get that equipment off the electric grid and powered as much as possible by such alternative energy sources as solar, wind, photovoltaic (PV), and geothermal.
