All PEX tubing carries one of three grades: PEX-A, PEX-B, or PEX-C. PEX stands for polyethylene (PE) cross-linked (X), and the grades are based on the various methods that manufacturers use to cross-link polyethylene molecules.

PEX-A represents the highest grade. Cross-linking occurs while the polyethylene is in a liquid form, resulting in even cross-links throughout the tubing. Known as the Engel or Peroxide Method, this production style yields PEX that has superior shape memory. PEX-A’s shape memory gives it several advantages, including added freeze resistance and flexibility. Kinks in PEX-A can be fixed through the application of heat from a heat gun, and only PEX-A tubing works with expansion-style fittings.

The Silane Method creates PEX-B tubing, with cross-linking occurring in solid-state polyethylene following pipe extrusion. The PEX-C Irradiation Method forms cross-links in PEX using beams of electrons after it has been shaped into tubing. This is the least common method of PEX manufacturing. PEX-B and PEX-C may be a bit stiffer than PEX-A, but are just as durable and reliable. See for more information.f1040500-1

Sizing a Gas Regulator


Gas regulators control the flow of natural gas (NG) and liquid propane (LP) to appliances and equipment that use them as fuel. The pressure of incoming gas is often unstable and excessively high. Regulators ensure that sufficiently-low constant pressure is maintained and sent to appliances. Proper sizing for an NG or LP regulator depends on several key factors which differ by application. Correct sizing is important due to the safety issues related to gas appliances. carries the Maxitrol brand of gas regulators. Maxitrol offers a regulator sizing calculator for free on their website. Use it to learn the relevant sizing factors and select the appropriate gas regulator for your next job.325-5a-1-1

How to Size a Tankless Water Heater


Tankless water heaters only heat water on demand, eliminating the standby losses associated with traditional tank-style water heaters. A Tankless water heater can provide hot water indefinitely – as long as demand does not exceed the heater’s flow capacity. There is a limit to the amount of hot water every tankless unit can produce in one minute. This gallons per minute (GPM) rating will be small for units designed to supply only a sink or two, but much larger for whole-house heaters. A heater’s GPM capability fluctuates based on the “temperature rise,” or the number of degrees by which the heater must increase the temperature of incoming water. 55°F ground water and a 105°F setpoint on a heater, for example, would require a 50°F temperature rise.

Tankless water heaters provide more hot water in warm climates and during warmer times of the year. See below for a chart from A.O. Smith that includes standard ground water temperatures across the United States.  Use this information along with anticipated output temperature settings to calculate your temperature rise. Always size based on the coldest incoming water temperatures if the heater will be used year-round. Make sure that the heater you choose can provide sufficient flow to meet peak demand at the required temperature rise. Typical showers use between 2 and 2.5 GPM, so a properly-sized heater would need to be able to provide 4 to 5 GPM at the necessary temperature rise in order to handle two such simultaneous showers. Specification sheets for tankless heaters display charts that indicate the maximum flow rates across the range of possible temperature rises.

Honeywell’s New Lyric Thermostat


A thermostat is nothing more than an on/off switch, activated automatically based on temperature settings, for a heating and/or cooling zone. Nevertheless, thermostats have evolved significantly over the years, including two relatively recent advances: programmability and internet connectivity. Honeywell’s new Lyric thermostat makes the most out of these features, offering users an efficient, smart thermostat.

The Lyric resembles the Nest thermostat and shares many of its features. Both the Lyric and the Nest allow remote access via the internet and smart phones while giving users the ability to view detailed energy reports. The big difference between the thermostats lies in their respective methods of efficiency maximization. Out of the box, the Nest operates like a standard, non-programmable thermostat. Occupants change the temperature as they normally would, and within a week the thermostat learns their habits and creates a customized program schedule.

Lyric thermostats rely on “Geofencing,” a non-battery draining feature of Android and Apple iOS smart phones. The geofence represents a selectable radius of either 500 feet or 7 miles (depending on your lifestyle) around the thermostat. During heating season (for example), the thermostat will reduce its setpoint temperature (“away mode”) when your smart phone moves outside your geofence and increase it (“present mode”) when it moves back inside the geofence. Multiple occupants of the same building can have their own geofences, and mode changes will always be based on the last person to leave and the first person to return. The Lyric targets tech-savvy people. You must own a smart phone and always have it with you to take full advantage of geofencing. Installation requires a smart phone along with an app geared toward do-it-yourselfers.

The Lyric’s Fine Tune feature ensures that ambient air temperatures feel as occupants would expect them to, using online weather data to access current conditions (including outdoor temperature and humidity levels) in order to incorporate them into system operation. Weather forecasts can conveniently be viewed on the thermostat at any time. Easy Comfort shortcuts allow homeowners to create custom temporary settings to override program schedules. Possible shortcuts include settings to be used during a workout in a home gym or during a large gathering in a particular part of a house. Another feature, Smart Cues, can be used to alert users to maintenance recommendations or link them to local professionals.

Additional features/benefits offered by the Lyric include multi-stage compatibility, IAQ terminals for devices such as humidifiers and ventilators, and the ability to operate without a common wire. The thermostat features a lighted ring that turns orange in heating mode, blue in cooling mode, and green in energy-saving mode. Its circular design was inspired by Honeywell’s famous “Round” thermostat that was first introduced nearly 70 years ago.

Art Cool Mini-Splits For Comfort—And Décor


Making a room cool doesn’t have to involve loosing a window. Today’s mini-split air conditioning units are the smart alternative to traditional window units, delivering comfort and decor all in one.ArtCool-LG-LAN096HNP_2-crop

Summer has arrived, and with the inexorable heat comes the inevitable hunt—for the perfect air conditioner, that is. Homeowners in search of a functional and fashionable alternative to conventional air conditioning units may want to consider a mini-split.  Mini-split air conditioning systems eliminate the need for the extensive wiring and ductwork required for central air systems, making them perfect cooling devices for older homes and new additions.  They also alleviate many of the problems associated with standard window units, namely they are quieter, don’t have to be removed “off-season,” and don’t present a bulky and unattractive appearance in the window. And, if it’s appearance that you are concerned with, LG’s Art Cool Mini Splits were made for you.

ArtCool-LG-LAN096HNP_11“The Art Cool series is a unique take on the tried-and-true mini split air conditioning formula,” explains Daniel O’Brian, a tech team member here at “While being functionally the same (and in the same price range as standard mini split systems), they offer a more visually pleasing indoor unit that can actually enhance room decor,” he adds.

LG’s Art Cool line basically consists of two options, both of which come in either air-conditioner-only or heat-pump models: Art Cool Mirror units feature a flat panel surface with smoked charcoal mirror finish, creating a sleek, contemporary silhouette; and the Art Cool Gallery unit provides a 20-by-20 inch square panel that works like a picture frame—allowing the consumer to insert their own artwork or photograph. Both units mount securely on a vertical surface with screws.

Mini-split air conditioning systems typically consist of two separate units: an interior evaporator with a fan and cooling coil, and an outside condenser unit; the two pieces are connected by a refrigerant line set. Mini-split systems are available in single room configurations, which consist of one indoor unit and one outdoor condenser, as well as multi-room configurations, which have two to four indoor units connected to a single outdoor condenser. Most mini-split indoor units are mounted on the wall, although there are some ceiling-mounted versions.artCool-LG-Mirrorfinish-b

The LG Art Cool Gallery unit is available as a single zone system in either 9,000- or 12,000-BTU sizes; the Mirror units are available in either single- or multi-zone systems. Choosing the appropriately sized unit is dependent on several factors, including the regional climate, whether the mini split system will operate as a cooling unit only, or a combination of cooling and heating, the number and type of rooms, the number of windows per room and the average number of people occupying the room at a single time. features a useful air conditioner sizing calculator to help consumers determine the correct amount of air conditioner BTUs needed for a given room, or set of rooms.

Typically, mini-split air conditioners will require professional installation by an HVAC (heating, ventilation and air conditioning) contractor, because the outdoor unit must be hard-wired to a dedicated circuit breaker and the correct amount of refrigerant must be used in the lines. offers a large selection of mini split air conditioners and accessories from the top manufacturers in the industry.  To learn more about the LG Art Cool systems, view the video below, or visit
