O&G Industries, a global construction materials and services company purchased and converted a Torrington, CT post office building into office space. As part of the conversion, O&G wisely decided to remove a 40 year old, 1 million Btu/hr oil fired boiler. They called in Stafford Mechanical Services to perform the conversion.
Stafford Mechanical Services focuses on designing and installing energy saving projects. After performing a comprehensive energy audit, they determined that natural gas boilers would provide superior energy cost savings compared to oil fired boilers. Triangle Tube’s 95% efficient Prestige boilers were the best replacements for the old boiler. Gary Reviczky, of Stafford Mechanical Services noted, “I selected the Triangle Tube Prestige boilers based on my experience with them. They have proven to be both easy to install and highly reliable.”
Two Prestige Solo 399 boilers, with a total input of nearly 800,000 Btu/hr. replaced the old 1 million Btu/hr. cast iron boiler. A Triangle Tube Mini-Mod Control provides for the outdoor reset feature to modulate the system water temperature, while the full parallel modulation maximizes the system’s efficiency by operating the boilers at the minimum possible firing rate. The Triangle Tube boilers increased the heating system turndown to nearly 8 to 1, which minimized boiler cycling and optimized the efficiency.
The Prestige boilers were vented using PVC piping in the existing 30 foot chimney. This prevented the need for additional holes in the wall and visible vent piping on the exterior. The wall mounted Prestige boilers freed up the floor space in the boiler room and allowed the piping to be neatly organized.
The old boiler consumed 4,850 gallons during a normal heating season. At a price of $3.60 per gallon of heating oil, this would cost $17,460. During the 2010-11 heating season, O&G’s heating cost with the Triangle Tube system was just $7404. This is a 58% reduction. The 2010-11 heating season was one of the colder ones in recent memory, so further savings are expected in the future.
Stafford Mechanical Services selected Triangle Tube Prestige boilers helped to convert an old post office to an energy efficient office building. The building’s owners, O&G Industries will have a more energy efficient workplace for many years to come.
