Project Background

Back in August 2016, Superior Realty Group installed the Stealth Boiler Control and Energy Management System at 41-20 46th Street, a 66-unit co-op building with a heating system running on gas. The heating system consists of a hot water and steam combination boiler. 

Management opted in to our Entech Pro service, where the Stealth components and settings are monitored and tweaked by dedicated Specialists. Due to the involvement of shareholders and board members, with varied input from each, a co-op provides its own unique challenges. Entech was up to the task to ensure that all are satisfied.

Energy Conservation Measures

Entech Pro Specialists implemented settings to ensure that the heat runs only when indoor and outdoor temperatures warrant it. Stealth’s advanced heat cycle trigger and Smart Cycles were put in place to ensure heat is established whenever there is a heat call and cycles self-adjust based on the outdoor temperature and indoor response. Hot water settings were applied to the boiler as well, ensuring adequate hot water supply while conserving energy.

Settings were adjusted regularly to reduce energy consumption, while at the same time responding to any on-site feedback.


A usage and savings analysis based on Heating Degree Days and actual fuel bills was performed for every season the Stealth was in place, with outstanding results year after year. Significant energy reduction and cost savings were realized, with an impressive 24-29% reduction in gas usage, and cumulative dollar savings of $63,024.
