While the new efficiency standards do not require manufacturers to use any specific technologies to achieve the new EF (energy factor) ratings, they’ve already necessitated a significant redesign effort from manufacturers. Additionally, the increasing unit sizes pose transportation and installation challenges that have yet to be fully understood.

Industry figures are estimates that are derived from the best available figures supplied by a sample of AHRI member companies. 

Lochinvar LLC introduced three new CREST condensing boiler models with 750,000 to 1 million and 1.25 million Btuh inputs during the AHR Expo on Tuesday. 

Superior Holding Inc. announced that it has opened Oklahoma Boiler Equipment, a sales support company. The new Oklahoma City sales arm joins Superior Boiler Technologies Inc. and Superior Boiler Works Inc. under the Superior Holding company umbrella.

A study released by the U.S. Department of Energy (DOE) confirms the M2G intelligent boiler control from Greffen Systems produces significant savings for heating buildings using hydronic boilers. The DOE’s “Building America Case Study,” which installed and monitored the controllers in Chicago, reported fuel savings up to 14 percent.

The standards, which were set by the Energy Independence and Security Act (EISA) in 2007 and implemented Sept. 1, 2012, required residential gas hot water boilers to meet a minimum AFUE of 82 percent; gas steam boilers, 80 percent; oil hot water boilers, 84 percent; and oil steam boilers, 82 percent.

Immensely popular in Europe, radiant cooling is steadily gaining popularity in the U.S. because of its potential to reduce energy consumption. About half of net-zero energy buildings use radiant cooling to help them achieve the balance between energy consumption and renewable energy creation.

Here's how wet heat technology helped a large college apartment building reach LEED-Silver certification, a Kentucky high school save up to 35 percent in monthly utility costs, and a local pizza restaurant go green.

My daughter Erin, along with her three sisters, grew up listening to me talk nonstop about hydronic heating. Erin recently bought a house with a furnace.

Inside the 15,000-square-foot house, the state-of-the-art heating system — complete with Wi-Fi and remote programming capabilities — is powered by a Bell & Gossett (B&G) pump system.
