Commercial

Gas Boiler Systems Initiative


Overview

The objectives of this Initiative include increasing quality installations operating in the condensing range, as well as optimizing existing systems to operate at the highest efficiencies allowable. Also, members explore ways to educate building contractors and design engineers about the importance of optimal maintenance protocols. The goals of addressing energy savings opportunities encompass:

  1. increasing the number of quality installed and maintained high efficiency commercial boiler systems
  2. educating building owners, design engineers, and contractors on what constitutes high efficiency in a given system, along with options for maintaining high efficiencies throughout the life of the boiler
  3. educating contractors on the importance of—and methods for—conducting quality installations and maintenance for high efficiency commercial boiler systems
  4. encouraging the creation of an enhanced efficiency metric for commercial boiler systems, in place of the current steady state boiler metrics, which better captures the infield operating efficiency of the boiler system throughout the year
How to participate

Initiative members demonstrate a comprehensive strategy for capturing savings through system optimization. They are required to:

  • Incorporate the CEE Equipment and Functionality Specification for boiler systems in an educational or incentive program
  • Undertake awareness and system optimization measures related to quality installation and quality operations and maintenance

Accomplishments

Members continue to view hybrid boiler systems and expanded use of controls as the paths to maximizing gas savings. CEE worked with members and industry to identify savings opportunities through retrofit controls and boiler sequencing. In addition, we established hybrid boiler systems as a path to rightsizing and leading to cost-effective energy savings.


Increasing the availability of efficient products in the marketplace and encouraging consumer uptake of those products are important strategies for realizing energy savings. CEE Commercial Boilers Initiative has helped guide the marketplace. Nearly all hydronic natural gas boiler manufacturers are now producing efficient products (See Hydronic Natural Gas Boiler Manufacturers by Product Efficiency). The efficient models they produce represent a growing share of the active products in operation (Active Natural Gas Hydronic Boilers by Thermal Efficiency).
