According to a recent industry report, growth in radiant heating sales in the first quarter of this year was largely driven by sales of floor heating cables.

WarmlyYours, a radiant heating company that specializes in electric floor heating systems, released their “Q1 2018 Industry Report ” earlier this week. Among other findings, the report showed that electric floor heating cable sales were responsible for a large portion of the 24.5% growth in consolidated sales for the company. Sales of the TempZone Floor Heating Cable grew 23.9% in the second quarter, which translated to year-to-date growth of 16.1%.

Pairing electric floor heating cable with an uncoupling membrane has become a very popular option for professionals and homeowners alike. In this picture you can see the various layers of a floor heating installation including the wood subfloor, thinset, the uncoupling membrane and heating cable, another layer of thinset, and the tile floor covering.

In addition, the Prodeso Membrane, an uncoupling membrane designed to accommodate the TempZone Floor Heating Cable product, has also increased significantly in sales in the second quarter (up 128%). When installed with the heating cable, the membrane significantly cuts down on installation time and provides long-lasting uncoupling benefits to relatively fragile floor coverings like tile. These features have helped grow the membrane from 45% of floor heating underlayment sales in the first half of 2017 to 57% in 2018.

A large part of the sales growth for both the TempZone Floor Heating Cable and the Prodeso Membrane is due to continued growth in the ecommerce channel. In fact, ecommerce now constitutes 19.4% of all WarmlyYours year-to-date sales, up from 8% last year. Most of this growth was with Amazon, which increased 349.8% in the second quarter. On Amazon, Q2 2018 sales of floor heating systems grew 427.9% and underlayment sales increased a whopping 3003.5%. The WarmlyYours report expects to see continued e-tailer sales growth well into 2019.

Despite the rapidly accelerating growth from digital avenues, Julia Billen, owner and president of WarmlyYours, stated in the report that the company will always place highest-priority on maintaining strong relationships with existing customers via direct sales.

“We’ve been in the radiant heating industry for a long time and some of our customers, from flooring installers to electricians, have been with us for nearly 20 years—in fact, they’re more like partners than customers,” said Billen. “And we will always place partners first because a website or app is never going to be able to beat the experience and knowledge of a professional.”

The Wasserman Eye Research Center is a culmination of a 50-year vision to house a world-class research and care center on the UCLA campus to preserve and restore eyesight. With offices in New York and Los Angeles, renowned architectural firm Richard Meier & Partners Architects designed the six-story, 100,000-square-foot Edie and Lew Wasserman building. Completed in April 2013, the three lower floors are dedicated to the expansion of the Jules Stein Eye Institute, making it a world-class research and treatment facility.

To accommodate for the Wasserman building, a plan was developed to demolish a seismically deficient portion of the adjacent Semel Institute building. Lead architect Michael Palladino was the principle-in-charge and Tom Goffigon, the project manager, worked closely with the Wasserman Foundation, overseeing the demolition project and design and construction of the new building. With a keen eye to detail, the architects kept sustainability top-of-mind. In fact, the University of California system recently became the first American university to have 100 LEED®-certified facilities – an impressive milestone and a testament to the university system’s dedication to responsible building practices.

Radiant System Takes Load off Forced Air

The first three floors were specified to include radiant heating and cooling, and Uponor was asked to help with design and product guidance. Working closely with Circulating Air, a Los Angeles-based mechanical contractor, Uponor helped design the system in conjunction with engineers and architects.

“The contractor had not worked with Uponor prior to this project so we helped them get trained and comfortable with our system on site,” said Jacob Ford of Keyline Sales, a local Uponor rep firm. “It didn’t take long for them to catch on, and they quickly advanced and found innovative methods to speed up installation.”

According to Ford, the building’s southern facing is a wall of glass, and the radiant heating and cooling system takes a huge load off the forced air system.

The four-man Circulating Air crew worked closely with Keyline Sales to ensure they installed the 16,000 feet of Uponor’s Wirsbo hePEX™ tubing efficiently.

“We were truly amazed at how quickly and easily we installed the piping for the radiant heating and cooling system,” Matt Fitzgerald, Circulating Air job foreman, said. “Receiving training on site really helped us, and our crew felt up-to-speed very quickly.” Also, Fitzgerald said that prior to training he was unaware how easy it was to make the connections to the manifolds and fittings. “I love how fast and easy the system is,” he said.

Uponor’s Wirsbo hePEX tubing uses ProPEX® expansion fittings which require one simple expander tool to make fast, easy connections that hold tight with up to 1,000 pounds of radial force. For contractors familiar with traditional copper or other rigid pipe connections, the ProPEX fitting system is a much easier, more reliable connection method.

The system hooked up to six manifolds and six cabinets divided between the three lower floors. “The installation was fairly straight forward,” Fitzgerald said. “And we didn’t encounter any obstacles that we couldn’t overcome.”

SunTouch launched the HeatMatrix uncoupling membrane that offers a flexible, easy-to-install solution for WarmWire underfloor electric radiant heating. Heating wire in HeatMatrix may be installed horizontally or vertically, providing professional installers and DIYers a convenient way to accommodate a variety of underfloor spaces. And because HeatMatrix has less rollback memory, it lays down flatter and faster, further easing installation.

HeatMatrix offers installers the versatility to vary wire spacing, allowing customers a choice of different heat outputs, based on floor and room heating needs.

The new membrane can be installed using modified thinset on top and bottom of the mat. The heating wire sits below the surface of the mat, providing greater protection from damage. In addition, SunTouch offers a thicker, constant diameter wire that offers increased durability and is made specifically for securement in the HeatMatrix membrane.

When Jason Ridgeway of Ridgeway Home Services, West Chicago, Ill., says he takes pride in his work because “we like what we do,” it’s pretty evident in his installations. Recently, at a new construction custom house in the trendy Wrigleyville neighborhood, the homeowner asked for a hydronic snowmelt system and hydronic floor heating.

The nearly complete radiant and snowmelt installation in Wrigleyville.

 

Ridgeway installed REHAU under floor metal plates with 1/2″ REHAU o2 barrier pipe. This allowed for the added floor radiant and even heat distribution with out adding to the floor height. The 2-man crew also added a 80-gallon indirect hot water heater and even snowmelt to the project in the front and back porch areas as well as walkways. Ridgeway custom built a hydronic panel to tie this all in.

Since this was a new construction site, the electrician had not been there to install power. “We had to get this up and running in order to heat floors so the flooring contractor could put down his floor which he would not do without floor heat running even though the furnaces have the place heated to 75 degrees. The electrical wires in the pictures are just temped in to a outlet until Sparky finishes,” says Ridgeway.

Ridgeway has a purge set up on the panel so they can purge all radiant floors from one location. “This entire system is filled with glycol so we want to switch hoses as little as possible,” says Ridgeway.

Some of the challenges were that the mechanical room was very small to begin with and now they are adding a boiler as well as piping and an indirect tank. “Things where very cramped,” says Ridgeway.

Quick Notes:

• According to Ridgeway, we have a boiler pump for the boiler on closely spaced tees. There’s a snowmelt pump not installed yet that will be over the door and a indirect pump for the indirect heater not installed yet. Then we have the one pump you can see which will actually be replaced with a Grundfos Magna series pump due to the multiple zones. We typically use the low loss headers but did not on this job.

• Balancing is done at the REHAU PROBALANCE manifold for the floor radiant. Temperatures are balanced with motorized mixing valves and HTP VISON 2 control Zones by Caleffi zone control.

• ProPress is great. I solder and braze with the best of them. I have done everything from 4″ massive boilers and chillers pipe work to 1/2 plumbing and no issues and no leaks. With a 20-year track record and 10s of thousands of fittings.

• All this and we’re allowed only 4 feet of wall in which to install. Not shown yet is the domestic hot water that’s going to be installed in front of the manifolds between boiler and panel.

• Zip ties are temporary until the clevis hangers show up; they did a great job holding pipe straight while they put it in.

IMG_8746• Snowmelt — we install tubing in the driveway, walkway and stairs and pump hot water through it from a boiler. The concrete then gets to a set-point temp above 32 degrees and melts the snow and ice on the drive turning it into water then vapor. This way no salting, plowing or shoveling is needed.
