AirTec Air Diffusers

Adam

New to SupplyHouse.com, AirTec air diffusers. AirTec from Rectorseal is a leading manufacturer of HVAC specialty products for minisplit and central air conditioning systems. AirTec is widely known in the HVAC industry for its line of uniquely designed air diffusers.

An air diffuser is an outlet for air distribution, and is usually located on the ceiling or the sidewall. They discharge the supply air in various directions, and are intended to mix the supplied air with the existing air in the room.

AirTec’s MV Classic air diffusers are strong, versatile and quiet. The one piece design eliminates the need for tedious mastic and external sealers, saving time and making installation simple. There are five grille patterns to choose from to allow optimum air flow for any room.  The stylish MV Retro design offers a simulated cast iron grille, and it has an authentic style handle which turns easily for full flow of airflow adjustment.

AirTec also offers limited clearance diffusers for side or top entry applications, and are perfect for when you find yourself in a tight squeeze. It utilizes the same construction as the MV diffusers just without the boot. We also sell AirTec’s TuffBox Register Boxes. Molded from polymers the adaptable one piece boot design of the TuffBox is flexible enough to conform to drywall backing eliminating leakage between the grille and the box.

You can find our range of Airtec Air Diffusers in our Sidewall/Ceiling Registers and Grilles section containing hundreds of products designed for supplying heated or cooled air to the room via sidewall or ceiling mounted grilles.

The Ultra-Fin Radiant Heating System

Tom

PEX pipe suspended in joist bays below a subfloor can be used to create convection currents in the bays if installed with proper air gaps and insulation. Its affordability and compatibility with relatively high fluid temperatures make the suspended pipe installation method popular for retrofit in-floor hydronic heating systems.

The Ultra-Fin system enhances suspended-pipe installations. Ultra-Fin plates attach to 1/2” PEX or 1/2” PEX-AL-PEX, with their louvers creating even convection in the joist. Use 3” tube hangers to hang tubing in standard joist cavities and 2” hangers in short cavities or when heavy insulation needs to be put in under the pipe.

Ultra-Fins provide greater water temperature flexibility and the opportunity to use significantly less tubing than other radiant heat installation methods. Additional benefits include reduced labor time, the ability to integrate with baseboards or radiators, and the chance to run tubing parallel or perpendicular to the bays.

Check Webstone First for Any Valve Needs

Tom

The name Webstone is synonymous with valves. SupplyHouse.com carries the full selection of Webstone valves for plumbing and heating applications. Standard ball valves can be purchased almost anywhere, but Webstone ball valves are available with features such as drains and T-handles. The T-Flow Ball feature on many drain valves allows handles to be reversed so that flow to the drain can come from either side of the valve.

Installing a tankless water heater? Webstone’s Isolator E-X-P tankless water heater service kits can be a great choice at a fraction of the price of similar kits sold by heater manufacturers. All kits include hot and cold drain valves for isolating a tankless water heater so that maintenance can be performed without draining the plumbing system. Most kits also include a pressure relief valve, and “Complete” kits also come with a gas ball valve and 3/4″ flexible gas connector. All Webstone items with a “W” suffix meet 2014 United States lead-free requirements.

Webstone is perhaps best known for their circulator pump flanges. Standard flanges work with almost all residential circulator pumps from any brand. Webstone flanges include shut-off valves to simplify circulator maintenance and replacement. Most flanges come with optional T-handles. Some models include a drain, and others include flow-check valves for preventing thermosiphoning to zones that do not need heat. Webstone’s Expansion Tank Pro Service Valve (part 41672) greatly simplifies hydronic heating installations. It links an expansion tank to an air eliminator and make-up water supply, while also providing drainage and isolation.

Control Honeywell Thermostats Online

Tom

Remote access to thermostats gives users the ability to monitor HVAC equipment and make adjustments when they are away from the home or building. This can be ideal for vacation homes, landlords, or simply people who want the ability to change heating and cooling settings before arriving home.

Honeywell’s RedLINK Internet Gateway works with any of their RedLINK-enabled thermostats. The gateway wires to an internet router and communicates wirelessly with thermostats using RedLINK signals (which tend to be as reliable as wires and have been successfully tested in homes up to 10,000 square feet). The Internet Gateway allows users to control thermostats online with Honeywell’s Total Comfort Connect website and apps, which require no additional usage fees. These resources give authorized users the ability to modify system (heat, cool, off, etc.) and temperature settings for multiple zones and buildings, while allowing them to provide up to six email-alert contacts. Each Internet Gateway can handle up to four thermostats, but multiple gateways can be accessed from the same online account. RedLINK thermostats work with several other wireless accessories including indoor and outdoor sensors, the Portable Comfort Control, and (on IAQ models) humidification equipment. For line-voltage applications, Honeywell offers the RedLINK-ready EConnect system.

Honeywell also offers several Wi-Fi thermostats, including select VisionPRO and FocusPRO models. Select Wi-Fi 9000 thermostats also allow voice-command adjustments to temperature settings. These Wi-Fi thermostats do not require an Internet Gateway. Instead, they connect to a building’s available Wi-Fi network. Honeywell’s Wi-Fi-enabled thermostats are accessible from the same Total Comfort Connect website and apps. They can serve as a more affordable way to gain remote access and can frequently be wired in place of existing low-voltage thermostats (note that a common wire is needed for operation).

Methods of Heat Transfer

Tom

Although many people assume that heat simply rises, it actually travels from warmer areas to colder areas in one of three ways: conduction, convection, and radiation. Conduction transfers heat through physical contact, as warmer molecules shift their energy to colder ones. Convective heat transfer occurs in fluids (liquids and gases), including air. Warmer air is less dense than cooler air and rises above it continuously, creating ongoing convection currents. In radiant heat transfer, waves of heat energy travel through space from a warmer surface to a colder surface. Radiation occurs on a daily basis whenever the rays of the sun heat people or objects on the earth. Forced air and baseboard heating systems take advantage of convection currents, which allow rooms to heat up more quickly. Systems that include radiators or in-floor tubing (radiant heat) primarily use radiation, which warms surfaces rather than only the air.

Freeze-Protecting Garage Thermostats

Tom

SupplyHouse.com carries sophisticated thermostats that offer features including programmability, remote access, wireless sensors, and high-definition touchscreens. While these features can greatly enhance residential and commercial HVAC systems, more affordable basic thermostats probably make more sense for simpler jobs. Among these are garage or storage heating systems, where freeze protection, rather than comfort, is the primary goal. We offer a few different thermostats that are ideal for low-temperature/freeze-protection applications. Honeywell’s TH1100DV1000 (vertical) and TH1100DH1004 (horizontal) PRO 1000 Series thermostats feature a selectable “garage mode” that allows temperature settings as low as 35°F. These heat-only low-voltage models can be battery powered or hardwired, and have simple backlit displays. ICM Controls Frost Sentry Garage Thermostats can also be set down to 35°F and, like the aforementioned Honeywell thermostats, have a positive off switch. These thermostats can also lead to cost savings when buildings remain go unoccupied for extended periods, as they can be set 5°F to 10°F lower than standard thermostats and can be shut the system down completely.

Expansion Tanks: What Are They and Why Are They Important?

Kristine

When water is heated, it expands, increasing the pressure in closed heating systems. Over time, these pressure fluctuations can damage the system’s components. An expansion tank is designed to alleviate this pressure and extend the life of your system. Here’s how it works.

ExpansionTanks-OverallDiagram1

Homeowners looking to maximize the efficiency and life expectancy of their heating and cooling systems may want to consider installing an expansion tank as an easy and inexpensive means of regulating water pressure and preventing costly damage to other components, including pipes.

An expansion tank is designed to relieve pressure in both potable water and closed hydronic heating systems. It ensures that constant pressure is maintained within the pipes so they do not get damaged from excess pressure. “An expansion tank in a heating system is an invaluable component that protects the entire system from the increased pressure and volume caused by heating,” asserts Daniel O’Brian, a member of our Tech Team at SupplyHouse.com.

“When water is heated, it expands,” O’Brian explains. “In a closed heating system there is only so much space in the pipes and the boiler. If the water is taking up more space and has nowhere to go, the pressure will increase and possibly damage the system, generally at its weakest points, until a leak or even a burst pipe results. An expansion tank is designed to relieve the stress, thereby increasing the life of the components in your entire heating system.”

Expansion tanks work by equalizing pressure throughout the system. An expansion tank is a small tank divided in two sections by a rubber diaphragm. One side is connected to the pipes of the heating system and contains water. The other side is dry and contains pressurized air, set at approximately 12 psi. As hot water enters the heating system, the pressure in the system increases. As pressure increases, the diaphragm in the expansion tank is pushed down. This compresses the air in the tank, creating more space for excess water to enter. This relieves excess pressure in the system and prevents pipes in the system from being damaged.

102-1-4

Installing an expansion tank is a relatively simple process that can typically be completed in less than an hour by a handy do-it-yourselfer. Some local building codes may require installation by a licensed plumber, however, so you should check with your municipal building department before proceeding with any installation.

Expansion tanks vary in capacity, ranging from tanks that hold as little as two gallons to large tanks that hold several hundred gallons. To determine the size needed for your system, SupplyHouse.com offers a handy Expansion Tank Sizing Calculator. Use it to determine the size and model of the expansion tank that’s best suited for your system.

Prices for expansion tanks start at about $30 for small residential tanks and climb up to $800 to $1,000 for larger, commercial tanks. Leading brands include Extrol expansion tanks, manufactured by Amtrol, which are used for hydronic heating systems; the Watts ET series and Bell & Gossett HFT expansion tanks, both designed for use with closed hydronic heating systems; and Therm-X-trol expansion tanks, for use with potable water open systems.

If your home already has an expansion tank in place, you may want to check it periodically to make sure that the tank is functioning. To check if the expansion tank is working properly, simply place your hand on the tank and feel its temperature. The top portion of the tank should feel warm to the touch, and the bottom portion of the tank should be room temperature. If the entire tank is warm, it is likely that the tank has completely filled with hot water, which occurs only if the diaphragm fails. If this happens, the tank must be replaced immediately.

SupplyHouse.com offers a large selection of expansion tanks and accessories from the top manufacturers in the industry. To learn more, watch the video below or visit SupplyHouse.com.
