Private Residence

Home Sweet Gigantic Home in Oklahoma City

When a local Oklahoma City family decided to build their dream home, no detail was left to happenstance. Each family member was encouraged to provide input on desired features, and the kids unanimously voted for an indoor basketball court and a gym, located in a separate building adjacent to the residence.

Hunter Mechanical & Controls, an Oklahoma City-based contractor, was in charge of the design and installation of the plumbing and the radiant heating and cooling systems. Hunter Mechanical has provided mechanical contracting services since 1986 and specializes in hydronic piping and geothermal systems.

Randy Hunter is the company’s principal and, as a radiant heating and cooling expert, also serves on Uponor’s Radiant Advisory Council. The main purpose of the Council is to help advise the industry and Uponor on market trends related to the radiant heating and cooling arena.

“The local rep in my area, Robert Reid with NSC Marketing, suggested that I get involved with Uponor’s Radiant Advisory Council, and I see it as a win-win for both of us,” Hunter said. “I believe the Council serves an important role setting high industry standards and Uponor gets to be apprised about what happens in the marketplace.”

The massive home has several energy-saving features, including radiant heated and cooled floors. The adjacent gym serves as a central plant for the mechanical room and Ecoflex® from Uponor was run underground to the main house.

“By using Ecoflex, we needed less trenching and fewer connections than we would’ve needed with a rigid system,” Hunter said. “And it provided a quicker installation time.”

The entire installation (including plumbing) took Hunter Mechanical more than a year, and the crew, sometimes as large as six installers at one time, quickly learned the ins and outs of working with Uponor’s crosslinked polyethylene (PEX) service pipe.

“In my opinion, the continuous length of flexible coils, and the ability to run Ecoflex Thermal Twin pipe underground to each manifold and associated hydronic air handler was a huge advantage,” Hunter said.

The project included 30 tons of water-to-water geothermal units (two five-ton units and two 10-ton units) to serve the central plant. When each of the seven separate zones is in need of hot or cold water, the three-way valves select the heating or cooling manifold (depending on need). The hot or cold water is then delivered to the zone through the Ecoflex pipe. The heat pumps are staged to provide the desired temperature of water — hot or cold — and each zone works independently.

The swimming pool has its own zone and can be heated or cooled depending on the time of year.

The home’s plumbing system consists of 2" Uponor AquaPEX® pipe with ProPEX® Engineered Polymer (EP) fittings, and Hunter Mechanical has many years of experience installing PEX.

“We prefer working with PEX because of the flexibility of pipe and the speed of installation,” Hunter said. “My guys love the Uponor pipe and connection system – fast and easy. And we have never have had an issue with leaks when we use PEX, and that saves us a lot of time and money in the long run.”

All in all, the home is a dream come true for this Oklahoma City family, and they look forward to making lasting memories for many years to come.
