Fittings for PEX-Aluminum-PEX


PEX-Aluminum-PEX, or PEX-AL-PEX, is PEX tubing with an embedded layer of aluminum. The aluminum serves as an oxygen barrier and keeps the tubing rigid. PEX-AL-PEX offers the additional advantages of less linear expansion and a larger diameter than standard PEX.

Due to the tubing’s different dimensions and aluminum layer, few options exist for fittings with PEX-AL-PEX. Standard PEX-Aluminum-PEX (i.e. the Uponor MLC MultiCor and Rifeng PEX-AL-PEX available on only works with compression fittings designed PEX-AL-PEX and Uponor’s MLC press fittings. PEX-AL-PEX compression fittings generally have male threads opposite the compression end, and must be connected to additional pieces in order to create couplings, elbows, tees, etc. MLC fittings require a costly tool and may not be a viable choice for small projects. Make sure to use a chamfering tool to prep PEX-AL-PEX prior to making a connection with either of these methods. Doing this creates a beveled edge on the inside of the tubing, which allows the o-ring to set properly.

Viega’s FostaPEX PEX-AL-PEX is not sized the same as standard PEX-AL-PEX. FostaPEX only works with Viega’s PEX Press fitting system. PEX Press fittings are also compatible with standard PEX tubing, but not standard PEX-AL-PEX. FostaPEX has its own prep tool, which peels the outer layer before the fitting connection can be made.fittings

Stay Cool With Art Cool


A little while back, Tim from receiving and I put together a video on LG’s “Art Cool” mini-split air conditioning systems.  These units can help you stay cool in this current heat, and they also look awesome.

With LG’s Art Cool systems, you can transform your air conditioner into a piece of art. Art Cool offers all the advantages of standard mini-split systems while giving users unmatched design flexibility.

Like all ductless mini-split systems, Art Cool installations include indoor evaporator units connected to outdoor condensers with refrigerant line-sets and electrical wire. This set up eliminates noise, wiring, and ductwork from the living space.

There are 3 options in the Art Cool line. Single-zone picture frame models, with 9,000 and 12,000 BTU options, display a painting or photograph of your choice. You can use their customizable art panel to enhance the appearance of any room.

Another single zone option is the Art Cool mirror units that provide a more traditional look and are a stylish alternative to the standard white.

Finally, Flex Multi Split Art Cool units work as part of multi-zone systems. They come with a black mirror front panel but are customizable with the ability to change the panel if desired. The extra panels are sold separately and come in a variety of styles to match your room or décor.

All three units come in air conditioning and heat pump models. Heat pump mini-split units can provide heating as well as cooling, but are generally not capable of serving as the sole heat source.

All the units also come with mounting brackets and a wireless remote control.  Check out the video below for some pictures of these units in action!

NOFP’s Solex


NOFP’s Solex is a cost effective, high-performance reflective foil radiant barrier and vapor retarder, designed to reflect radiant energy and retard moisture migration in a building.  The core of Solex LT is 1/8″ thick while Solex comes standard at 1/4″ providing additional insulation value and durability.  Both Solex LT and Solex are available in multiple facing combinations which are thermally bonded in a unique process that provides a long-term quality finish.  This unique core has state-of-the-art reflective polymeric film laminated to both sides.

Solex reduces the radiant heat gain of the sun under roofs into the building envelope when used in conjunction with a minimum of 3/4” airspace.  Installed in this manner, Solex can reflect up to 97% of the radiant energy thereby reducing the heat buildup/loss as compared to a non-insulated metal building.  Solex’s lightweight, easy to use, and energy saving material helps reduce the energy consumption of your building enclosure. It is tear-resistant, moisture-proof, bug-resistant, and uses non-toxic materials that can be safely installed without the use of protective clothing.  All that is needed for installation is a utility knife, tape, and safety glasses.

The Solex and SolexLT range of products can be used for new construction as well as retrofit in a variety of applications, such as post frame, horse, dairy or livestock buildings. It can be used for finished walls, building insulation, condensation control, and as a thermal break and vapor barrier.  Solex and SolexLT can be perforated for applications where a vapor barrier is not needed such as behind siding or in an attic.solex

Dual-Approved hePEX from Uponor


Most oxygen-barrier PEX does not have the appropriate approval codes for use with potable water and should not be installed in domestic plumbing applications. Uponor’s hePEX recently received NSF approval, making it one of the few types of oxygen-barrier PEX on the market that can also handle domestic water.

Fresh oxygen causes ferrous metal components (cast iron circulator pumps, boilers, etc.) to rust in hydronic heating systems. Since oxygen from the air can penetrate PEX tubing (even when the PEX is embedded in a concrete slab), an oxygen barrier is needed in most heating systems. The aluminum layer serves as the barrier in PEX-AL-PEX tubing, while a layer of ethylene vinyl alcohol (EVOH) is applied to the outer layer of standard oxygen-barrier PEX.  This layer normally makes the tubing unsafe for potable systems, but this is no longer the case with hePEX tubing.

Current hePEX tubing carries cNSFus pw-rfh ASTM F876/877 and PEX 5006 ratings stamped on the tubing. Older hePEX was manufactured with the same formula and would be safe in potable systems. Now you can use extra hePEX tubing from a heating job on your next plumbing project or buy hePEX coils to meet all your PEX tubing needs. As always hePEX carries the PEX-A grade, making it more flexible and easier to work with than PEX-B and PEX-C pipe. PEX-A pipe also offers added freeze-resistance, compatibility with expansion-style fittings, and the opportunity to fix kinks by applying heat.

“Which Line Set Do I Need?”


I recently spoke with Nicole from customer service and she told me that a number of people call and ask about Line Set sizing.

A line set is used to connect an indoor evaporator unit to the outdoor condenser in a ductless mini-split air conditioning system.  A line set includes a supply and return line, which runs cooled R410-A refrigerant between the outdoor compressor and the indoor cooling unit to push cold air into the room.

You size these units based on specs from the Indoor unit.  We put together a video where Nicole explains how to do this on our site.  Check it out.

QuikSEER+ WattSaver


With summer upon us, the QuikSEER+ Wattsaver from Mainstream Engineering is an innovative and cost-saving electronic control that operates in the cooling mode of an existing air conditioner or heat pump.  By varying the airflow of the blower motor, this technology optimizes the airflow of the air conditioner, thus reducing the total energy consumption and improving humidity and mold control.  As the blower speed is operated at slower speeds, the humidity removal is also greater.

The QuikSEER+ does not provide a continuously variable speed selection, instead it only provides the speeds already available on a blower motor (up to 3 speeds).  The QwikSEER+ board simply decides which one to use every time the unit cycles on, rather than the installer selecting one of the speeds during the install.  This minimizes power consumption, resulting in savings.

Back in January 2013, the QuikSEER+ was rated by the U.S. Department of Energy as a cost-effective A/C solution that increases energy efficiency, and stated that, “Simply installing the QwikSEER+ WattSaver control board in line with the existing PSC blower motor now allows homeowners to increase the A/C energy efficiency rating (EER) by 8%–14%.”  Some Deluxe systems can also provide similar savings, but will cost thousands of dollars, whereas the QuikSEER+ will leave you with change from $154 at
