Event Details

Although high-efficiency condensing boilers have been available in the residential market for many years, consumer acceptance and market penetration is low. One contributing factor is that many mechanical contractors believe condensing boilers don’t achieve their listed efficiency. For this project the team characterized existing boilers and determined practical, cost-effective steps to improve performance through retrocommissioning and improved installation.

Results show that the installed systems were energy efficient and had good performance. All systems achieved desired efficiency levels of around 90%. The team found that, while it is possible to increase boiler efficiency by a small margin through retrocommissioning and optimization, it requires a lot of work for a small amount of savings, and systems were already achieving high levels of efficiency without intervention. New installations also achieved high levels of efficiency with only basic installation requirements, such as following the manufacturer’s recommendations for outdoor reset sensor locations and setting the temperature curves based on the emitter type in the home.

Join us for a live webinar where CEE’s Director of Residential Programs, Rebecca Olson, and Senior Research Engineer Ben Schoenbauer will dive deeper into project findings and discuss quality installation and retrocommissioning best practices that can be integrated into utility conservation improvement programs.
