In Eagle County, Colorado, local authorities not only promote energy sustainability, but insist on it. Any residential project that incorporates more than 200 square feet of snow melt, for example, must mitigate the load with an offset the draws upon a renewable energy source. So the county required owner to mitigate snowmelt energy draw with alternative energy or pay a hefty fee.

For Mustafa Aydin, president of American Plumbing Heating & Solar in Edwards, Colorado—an independent, family-owned plumbing and heating company that prides itself in personalized customer service—the county’s demand represented an opportunity for innovative energy planning. His client was gutting and rehabilitating a 7,000-square-foot home in the Red Sky neighborhood of Wolcott, Colo., completely redesigning its infrastructure to include radiant floor heating, 3,000 square feet of outdoor snowmelt, improved domestic hot water, and the comfort of a heated, year-round 1,500-gallon hot tub. The challenge for Aydin was to determine the loads for all the needs and design a system to support it.

 

Before Aydin had consolidated his design options, he knew immediately where he would source the core components: “I’m a Viessmann installer and have been for many years, I won’t install anything else.”

For design support, Aydin turned to Eric Anderson, a hydronics technical support specialist at Ferguson Hydronics in Denver. He was tasked with creating a system that would integrate solar thermal—the renewable energy resource—with condensing boilers to serve all four loads seamlessly and efficiently.

 

“At the highest level, we thought of the solar thermal contribution in two tiers,” says Anderson. “Its top priorities would be serving domestic hot water needs and the hot tub; at the secondary level, it would support the condensing boilers with the radiant heating and snowmelt loads.”

“When you have an involved project like this,” Anderson explains, “you start with a heat loss study to assess the loads. How much DHW do they use or need? What’s the load from the outdoor spa? Anderson ran a TSOL, a solar thermal computer simulation program that analyzes load within the context of the location’s climate and weather. The resulting analysis formed the basis for design that includes nine, 4’ x 8’ solar panels on the roof, and two Vitodens 200 wall-mounted condensing boilers. The solar system ties into two 120-gallon single-coil stainless steel tanks—one for DHW, the other to preheat water for the boilers (reducing their load)—a plate heat exchanger for the outdoor spa’s hot tub, and a 650-gallon stainless steel atmospheric tank that serves as a buffer for the solar thermal system, and as a contributing source of energy for the radiant heat and snowmelt loads.

 

This installation utilized a Caleffi hydro separator, iSolar control, a diverting valve, Z-one valves, 6762 Series thermo-electric zone valves, 132 Series QuickSetter balancing valve and a 573 Series AutoFill combination valve with backflow preventer.

In addition to supplying the panels, boilers, and tanks, Viessmann provided the panel line set and the boiler controls. The line set—prefabricated from stainless steel and pre-insulated—include sensor lines in the insulation for easy integration into the controls, and, says Anderson, “really solid, high-temperature O-ring connections for the panels, which means there’s no need for us to do soldering on the roof.”

 

Cascaded for maximum efficiency

A carefully planned mechanical room manages the flow of water, and allocation of energy, between the solar and boiler sources, using an integrated array of three-way valves and the intelligent application of the boilers’ controls. “We have the controller set for a cascading strategy that encourages the maximum amount of condensing,” says Anderson. The lead boiler usually fires at 25% to 30% of its peak modulation; when it exceeds 40% – 50%, the second boiler kicks in and the two modulate down again. “The whole goal,” Anderson says, “is to fire at the lowest rate for highest efficiency.”

While the system is complex, sourcing components from Viessmann made the project easier. “It’s the only boiler system I spec,” Anderson says. “Whether it’s solar, controls or boilers, everything’s thought out as a system. For me, that means peace of mind.”

 

American PH&S had an artist come in and paint an aerial view of a motorcycle on the mechanical room floor. Discovering that the owners are big motorcycle fans during his initial bid process, Aydin surprised them with the motorcycle design. The color just happened to match the first motorcycle the owner ever bought. They were delighted with the attention to detail. “I like to add a personal touch when finishing a project like this.  In this case, the homeowner is a Harley Davidson fan, so we added the motorcycle image to the floor.  It was a surprise gift for the homeowner and he loved it!” said Aydin.

Ultimately, the homeowner was satisfied to have an alternative energy source for his home and a snowmelt system in his driveway.

Early last month at its U.S. headquarters in Warwick, R.I., Viessmann held a two-day event in which the company celebrated its 25 years of operation in the states. The first day, September 9,  was a special VIP event where more than 150 guests attended the anniversary day of celebration with speeches, gourmet luncheon and a walking tour of the Warwick facility featuring the newly introduced Vitocrossal 300 CU3A, as well as popular products like the Vitodens family of condensing boilers. Honored guests included long-time customers and key partners, public officials from the state of Rhode Island, local academia, Viessmann U.S. staff, top management from Viessmann Canada and senior management from Viessmann global corporate headquarters in Allendorf, Germany.

 

The celebration was highlighted by speeches from Prof. Dr. Martin Viessmann, CEO and president of the Executive Board, Dr. Michael Luz, managing director of Viessmann U.S., Rhode Island’s Lt. Governor, Daniel McKee, Rhode Island Secretary of State, Nellie Gorbea, and the mayor of Warwick, R.I., Scott Avedisian.

In his keynote address, prof. Viessmann spoke about the growth and evolution of Viessmann’s investment in the U.S. market which started in the 1970s, the importance of the company’s enduring trade partnerships with its customers and Viessmann’s long standing commitments to energy efficiency and sustainability. Prof. Viessmann specifically talked about the company’s precedent-setting accomplishments such as reaching high standards of energy efficiency and German climate policy targets well before the 2050 date established by the German government.

“As a result we have increased energy efficiency by more than 20% and increased our share of renewable energy by 60%. In doing so, fossil fuel consumption has been reduced by 70%, and CO2 emissions by 80%. This shows that it is not the technology that holds up progress in the heating markets because technology is already there today.

 

“We see this in our comprehensive range of products, which are designed to respond to challenges of the future. Together with our customers we can make an important contribution to the success of the energy transition within the framework of our successful trade partnership,” said Martin Viessmann.

When talking about the future of company, Dr. Luz said, “To 25 successful years for Viessmann in the U.S. they have been successful because of you, our customers our partners, and our colleagues for that we thank you. We are looking forward to the next 25 successful years in the U.S. we are looking forward to continuing working with you, serving you and your customers. Most importantly we are looking forward to doing our share preserving the precious resources of our planet and to leaving this planet in better condition for the next generation after us.”
