The Scale Free System delivers chemical-free solutions to provide environmentally friendly water treatment products for heat transfer systems. 

The FlexCore 1.5 stainless steel, symmetrical fire tube boiler achieves 95.1 percent AHRI-certified efficiency and utilizes a precisely temperature-balanced FlexCore heat exchanger, which provides high efficiency and maximum durability. 

To figure out which efficiency improvements make the most sense, owners usually turn to HVAC professionals to conduct comprehensive energy audits, which are used to thoroughly evaluate existing mechanical systems. While energy audits have traditionally occurred on-site, some firms are offering virtual energy audits.

Long before Americans had access to natural gas, propane, fuel oil, or electricity, and long before there were automatically controlled central heating systems, wood was the most commonly used heating fuel.

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.
