HAMCO Heating and Cooling enhances energy efficiencies of retirement community.
St. Elizabeth Villa in Hamilton, Ontario proudly offers “care-free independent and assisted living” for up to 90 retired adults. Overlooking Canada’s Golden Horseshoe region atop Hamilton Mountain, the retirement apartment building has operated at full capacity since the early 1980s.
For several years, residents and their caregivers dreaded the thought of dealing with intermittent heating system shutdowns, often caused by leaky piping. When a new ownership group purchased the complex last year, they immediately saw the heating system problem as a major drain on operating budgets, so they gave HAMCO Heating and Cooling, of Hamilton, Ontario, the challenge of coming up with a sustainable solution.
After a thorough assessment of aging heating equipment and leaking piping in the six-story building’s rooftop mechanical room, Jordan Vasilak, shop foreman and manager of installations at HAMCO, recommended a proven and reliable solution that would reinforce the retirement community’s “care-free” value proposition.
“The new operating company of St. Elizabeth Villa is thrilled with the new Baxi high-efficiency commercial boilers and high-pressure and corrosion resistant aquatechnik PP-RCT 125 piping system we have installed,” Vasilak said.
Vasilak continued, “It is gratifying to know that this proven equipment has helped us meet all of the Villa owner’s needs for dramatic improvements in operating costs, energy conservation and efficiency and environmental impact, not to mention a healthier and more comfortable quality of life for residents.”
Dramatic savings and a more comfortable quality of life
HAMCO replaced the building’s five low-efficiency atmospheric boilers (rated at 65 percent efficient) with a cascading system of five high efficiency Baxi Luna HT 1.100 modulating, condensing commercial boilers (98 percent thermal efficiency), which generate a total of up to 1,895,635 BTU/hr (rated heat input). The heating contractor also changed out corroding storage tanks with six 106(US)- gallon insulated Baxi dual-coil indirect storage tanks made of steel, coated with a double enameling on the inside surface.
Since the boilers are staged in operation, the system provides significant efficiencies, plus built-in redundancy, ensuring continuous performance even when one of the boilers is being serviced. This reliability factor was not available with the previous system, so every time the old system went down it created an emergency situation for the apartment building community, according to Vasilak.
“Because we are trained and certified Baxi installers we were able to offer the building owners the Baxi 10-year extended parts and labor warranty,” Vasilak noted. “This protection adds further peace of mind for our customer. In addition, the local gas provider (Union Gas) is providing attractive rebates for the owner, and they project that the Baxi boilers will generate a payback of less than 10 years.”
HAMCO addressed problems associated with the leaks in the former system by changing out the failing metal piping in the mechanical room with aquatechnik PP-RCT fusion pipe and fittings, using ¾- to 4-inch diameter piping.
“Before commissioning, we pressure tested the new system, and we were amazed to find just one small leak that we resolved immediately. That just does not happen with metal piping installations,” Vasilak said. “This is our first experience with aquatechnik fusion piping, and we expect to move the majority of our work over to this proven polypropylene piping solution. We are impressed with the aquatechnik high velocity capabilities and high pressure ratings. Its wear characteristics and long life span are better than anything else we have used over the years.”
While the piping is new to North America, with authorized regional distribution throughout the U.S. and Canada, aquatechnik has been a leading manufacturer of PP-R and now PP-RCT fusion piping solutions in Europe and other parts of the world since 1985. The aquatechnik piping system is certified to NSF/ANSI Standards 14 61 51 and 372. Systems installed by trained aquatechnik contractors come with 30-year warranty and insurance protection.
Embracing new tech and a better way of doing things
“Our contracting firm has been serving the Golden Horseshoe region for seven decades, and we are always open to taking on new challenges and exploiting new technology,” Vasilak said. “There is wonderful new technology in our industry that enables contractors to generate sustainable energy savings and a whole better way of doing things.”
Vasilak believes that Baxi high efficiency heating and aquatechnik heat fusion piping solutions give HAMCO “a leg-up on the competition.”
The mechanical contractor sees himself as a student of the heating and cooling business. He studied electrical and mechanical engineering in university, and has earned licenses in gas, electrical, sheet metal and refrigeration. The Vasilak family invests in continuous learning and certification for all 24 specialists employed by HAMCO, which now serves the broader Golden Horseshoe region of Ontario.
“The most valuable belief we have all learned is from my grandfather, HAMCO chairman Lawrence Vasilak, who purchased the family business in 1946,” Vasilak explained. “He always reminds us that if you give your customers good value and meet their needs, they will be your customers for life.”
