We use American Aldes to supply the majority of our ventilation system components, including hardware airflow controls, duct, fittings, exhaust fan units and more! Their high-quality components and know-how help us to provide fresh, clean air to residential construction clients of all kinds.

Grundfos pumps have proven to us over time to be nearly bulletproof, as well as affordable, with a wide range of products for all of our applications. These little guys have given us years of trouble free, reliable operation on hundreds of systems. Plus, as a very popular pump manufacturer, if you do ever need a replacement and can't wait for us to ship, it's probably available at half a dozen local supply houses!

On many projects, lightweight aluminum plates are used to facilitate heat transfer between the radiant tubing and the floor, such as in many joist installs, radiant ceiling or walls, or above the floor sandwich installs. When expensive heavy gauge plates are not required, we use locally manufactured, high quality Newland Lightweight Plates. We stock two widths for most jobs, or we can have plates made to order in custom widths and configurations for each project's needs, Newland gives us a nice snug "omega groove" channel around the tubing, allowing for nearly 360 degrees of contact between the plate and the tubing with no silicon or other additives necessary. This gives us great contact for conduction and great performance at a very, very competitive price!

For many applications, or by customer preference, we often use high-quality RauPEX and its associated components as well, especially when visible flow rate monitoring is desired in a contractor-friendly preassembled manifold package. Rehau also makes the best over-the-subfloor radiant panel on the market, Raupanel, which we recommend whenever a prefab panel is desired for labor savings and high performance output, and it's too late to use Warmboard.

NRT prefers Runtal radiant panel baseboard, custom radiant panel emitters, and towel warmers to provide attractive and efficient supplemental heat options for our clients. Runtal provides us with top quality stock and custom services, and allow us to design around a wide range of water temperatures to get that extra boost when we need it.

With superior workability, excellent manifold accessories, and a great price, NRT now favors Mr. Pex in most of our systems. In fact, we thought it was good enough to start stocking it! Formulated by one of the key former engineers for Wirsbo, and with years of excellent performance in the field, we finally decided after years of deliberation that others had done the "beta testing" and this tubing was ready for us to put in our systems.

NRT uses Tekmar's radiant controllers to provide top notch performance in our systems, with features such as constant circulation, variable speed injection, indoor and outdoor reset control, boiler purging, staging heat sources or emitters, setback capabilities, soft starts, DHW integration and more! Tekmar's microprocessor controls help us minimize water temperatures, maximize efficiency and comfort, and address a wide range of potential radiant problems such as expansion noise and short cycling.

In some applications, lightweight plates are simply not adequate or desirable. When we need to drop water temperatures or increase output in over or under floor applications, we often turn to the Thermofin product line, created by Radiant Engineering, Inc., the industry leader and pioneers of extruded aluminum plate design.

In our ventilation systems, we often use high-quality Venmar heat and energy recovery ventilators, which are especially well suited for use in colder climates. Quiet, efficient, easy to use, with built in filters to provide fresh, clean, tempered air to your home and guarantee good indoor air quality, year-round!

When it comes to low-mass, high performance aluminized subfloor panels, Warmboard is king of the heap, providing a subfloor and a radiant panel all in one, that is installed just like the subfloor decking in 4x8 sheets! If prefab panels are the way to go for your project, we say that Warmboard provides the best value overall; a competitive starting price compared to other prefab panels (don't forget to subtract that 3/4" subfloor you won't need!), excellent service, the least overall install labor and extremely powerful output all in one; it's a pretty compelling package with years of proven performance behind it. It's even easier with our Mr. Pex systems' PEX-AL-PEX pipe!

NRT often uses Wirsbo tubing in our designs. Hepex, non-barrier Aquapex, Pex-Al-Pex Multicor, all industry benchmark tubing products with fantastic quality assurance at the factory and more than 30 years in the field help us to be sure that every foot of tubing in our systems is reliable now and for years to come. Each tubing type is suitable for different applications, so Wirsbo gives us a "tubing palette" for all our needs.
