Problem Recognition

Riverbend at Lansdowne Woods originally had four (4) 750K Btu Domestic Weben-Jarco gas boilers installed and CroppMetcalfe, an established HVAC contractor in the area, was frequently there doing repair work. “The building is 20 years old and the boilers had constant pump and system control issues, so we were cannibalizing parts from the boilers to keep at least two in operation,” said Tom Davidson, part of the HVAC team at CroppMetcalfe.

At its inception, the building had established a fund to replace aging building components. Craig Magargel, Building Manager at Riverbend knew it was time to seek a replacement. “We were spending over $10K annually  just in repair and maintenance costs to keep the existing units running,” said Craig. “We wanted to look at higher- efficiency options, and CroppMetcalfe suggested we consider ÿ�մ������ Tankless.”

Efficiency Gains

The local Commercial Technical Sales Manager for ÿ�մ������, Davis Trexler was contacted and walked the property with Tom, Craig and CroppMetcalfe Sales Engineer, Mihn Le, which resulted in a presentation to the Condo Association Board and building engineers. “Davis demonstrated how the ÿ�մ������ Tankless Rack System would provide three times more redundancy, deliver energy savings, and supply a storage tank that services our penthouse level,” said Craig. “We also loved the idea that we would never experience any downtime, even when the units were undergoing scheduled maintenance. That really was not the case with the boilers.” Davis with ÿ�մ������ adds, “I explained how our new SENSEI™ Commercial Racks have 97% thermal efficiency and easily serviceable components, greatly reducing their energy consumption and maintenance costs.”

Purchase Decision

in the Spring of 2019, CroppMetcalfe installed the 2.4m Btu system comprised of two (2) TRS06 Freestanding Racks with 6 SENSEI CU199 tankless units pre-installed on each rack. “The ÿ�մ������ Tankless Racks came pre-assembled which made them extremely easy to install, just plumb to the manifolds and connect your gas supply and you’re good to go,” said Tom of CroppMetcalfe. This ease of install makes for satisfied customers. “The installation was on-time, on-budget and made for an overall great experience.” said Craig, “We are very enthusiastically invested in our new ÿ�մ������ Racks and how they have transformed our domestic hot water system while already reducing our operating costs.”
