Energy Star certification is an important distinction for HVAC manufacturers’ products to achieve. The designation recognizes highly efficient performance, and 2017’s list of the most efficient boilers delivers a bevy of products from a wide range of manufacturers.

The Noritz Residential Combination Boiler (NRCB) allows for simultaneous residential domestic hot water and space heating and performs at 95 percent AFUE. Unlike traditional combination boiling systems, which can provide only space heating or hot water at any given time, the NRCB’s simultaneous capabilities are easy to control and especially beneficial for applications that do not store or deliver heat energy efficiently.

The Free Flex Ultra-High Efficiency Commercial Condensing Boiler offers a thermal efficiency of 95 percent and features Bryan’s weld-free design. The Free Flex permits field access to the heat exchanger for cleaning and an unprecedented tube replacement.

Anytime you conjure up a new idea about how a heating or cooling system might work, test it against the laws of thermodynamics.

The Sierra Club, a grassroots environmental organization, announced it would be joining nonprofit public interest law organization, Earthjustice; the Consumer Federation of America; the Natural Resources Defense Council (NRDC); and a coalition of state attorneys general in filing a lawsuit against the Trump administration over the U.S. Department of Energy’s (DOE) delays in issuing new energy-efficiency standards for ceiling fans, freezers, boilers, and commercial and consumer goods.

The ClearFire-CE (CFC-E) condensing boiler can achieve up to 99 percent efficiency due to its enhanced AluFer^® firetube heat exchanger and dual temperature returns.

Many of the products central to everyday aspects of American life — from homes to cars to electronic gadgets — are no longer made to last.

In 2008, my wife, Dorian, and I moved to Albuquerque from Colorado to establish Outlaw Mechanical. Colorado taught me a few things about the need for tough, durable HVAC systems, so, today, about 40 percent of Outlaw’s work is hydronic.

With failing boilers and an inefficient heating system, the historic Zion Episcopal Church needed guidance and help. The latest high-efficiency condensing boilers from Weil-McLain provided the answer to solve their heating woes.
