Weil-McLain’s WM97+ Boiler


The WM97+ wall-mounted, gas-fired, hot water boiler from Weil-McLain sets new standards for quality and efficiency. With seasonal DOE efficiency ratings of over 95 percent, the three available models waste minimal amounts of fuel. They feature a built-in primary circulator, low water cutoff, and expansion tank (WM97+ 70 and WM97+ 110 only). Convertible to propane with an included kit, the boilers contain stainless steel heat exchangers, three-zone circulator controls, and indirect water heater connections. The WM97+’s color LCD display conveniently displays text-based error codes, eliminating the need to check the manual every time a problem occurs. The boiler is designed for direct vent combustion.

Take advantage of an Aqua Logic indirect water heater to use the boiler’s energy for your domestic water needs. In addition to connecting directly to the bottom of a WM97+ boiler, the AquaLogic provides many benefits of its own. It offers a stainless steel tank, coil, and connector pieces, along with a vacation mode for energy savings during periods of extended non-use as well as personalized scheduling options. The AquaLogic minimizes temperature swings when multiple fixtures run simultaneously and includes two tank temperature sensors.

The Colors of PEX Tubing


PEX tubing normally falls into two main categories: PEX with an oxygen barrier and PEX without an oxygen barrier. PEX with an oxygen barrier is designed for closed-loop space heating systems, and will normally be either red or white. It is usually not approved for use with potable water. PEX without an oxygen barrier is designed primarily for use in potable water plumbing systems. It is available in red, blue, and white to make classification of water lines easier (red for hot, blue for cold, white for supply lines or single-color systems). The color of PEX does not change any of the tubing’s ratings. There would be no problem, for example, using blue PEX for hot water lines or red PEX for cold water lines. Other types of PEX include PEX-Aluminum-PEX, which is often orange, and PEX for reclaimed water, which is usually purple. Gray plastic pipe is often polybutylene — an older type of pipe that is similar to PEX, but that has a different inside diameter and chemical composition.

Fasco Motors


Fasco Motors have arrived at SupplyHouse.com just in time for the heating season! Fasco Motors manufactures top of the line OEM replacement Motors and Draft inducers for the biggest names in the HVAC industry. Here you can find replacements motors and draft inducers for Lennox, ICP/Heil Quaker, Trane, York, Goodman, and many more.

A draft inducer is a fan that operates when there is a call for heat. It blows air into the vent at the beginning of the heating cycle to ensure the vent to the outside is clear. If the vent is not clear, combustion gases will get inside the home and cause problems. The draft inducer starts operating before the flame is lit and continues running while the flame is burning. If the draft inducer is supposed to be running and the furnace realizes it is not, the furnace will shut off. A furnace will not run without the draft inducer, which means you will not have heat. Don’t get stuck without heat this winter. Fasco Motors are in stock and ready ship today!

Chase Away Winter’s Chill With Radiant Heating Systems


Looking for a comfortable even heat throughout your home that is both cost-effective and energy efficient? Consider the benefits of a radiant floor heating system to do the job.


Drafts got you down? If your goal is to achieve even, comfortable heat and warm floors, then you may want to look into installing a radiant heating system for your home.

Radiant heating systems are installed in or below the floor of your home, and distribute heat evenly and comfortably. The heating coils first warm up the floor, and then the heat rises gradually throughout the room, warming the air and all of the furnishings so that the entire interior becomes snug and toasty.

“Radiant heat holds many advantages over typical convective heating methods,” notes Daniel O’Brian, a tech team member here at SupplyHouse.com. “Radiant heats the whole room evenly, so there is no ‘cold at the floor – hot at the ceiling’ effect. It will even heat the surface of the objects in the room, greatly increasing comfort.”

“Because airflow is negligible in a radiant system, there is less heat loss due to drafts, and in general the thermostat can be set lower while remaining comfortable,” O’Brian continues. “On top of that, the water temperature required for a radiant system is much lower than traditional systems. A properly configured radiant system can save you big bucks on utilities.”

In addition to comfort, radiant heat is aesthetically pleasing, because all of the components are tucked away out of sight—there are no radiators, baseboard heaters or hot air returns in view. Radiant heat is also silent, eliminating much banging, whistling, creaking, popping, rattling and humming of conventional heating systems.

There are two primary types of radiant heating systems, hydronic and electric. Hydronic systems are the most common and use hot water passing through PEX tubing to heat a space. Electric radiant heat uses electric cables or mats to heat a space. Radiant heat can be installed in both new construction and in existing homes, and there are several different types of installations, depending on what type of home construction is used. Hydronic tubing can be installed in a cement foundation when it is being initially poured; or the tubing can be installed in an “over-pour” on an existing foundation. Tubing also can be installed in between the floor joists with or without plates; or it can be installed above the subfloor using a specialty product such as Quik Trak.

Radiant heat is also an energy-efficient option for many homeowners. Although the initial installation cost may be 10% to 25% more expensive than a conventional heating system, a properly designed and maintained radiant heating system can cost 25% to 50% less to run and maintain. Also, the life expectancy of a radiant heat system is typically 30 to 45 years, double or even triple the 10 to 25 year life expectancy of a traditional forced air furnace. Radiant heat also can increase the value of your home at resale, since these systems are considered a highly-desirable option among home buyers.

SupplyHouse.com offers a large selection of products and packages for installing radiant heating systems from the top manufacturers in the industry.  For more information, including a radiant heat calculator, visit SupplyHouse.com.

Sizing Bath Fans


When you’re picking a new bathroom ventilation fan, you will often come across the term ‘CFM.’ An abbreviation for cubic feet per minute, CFM quantifies the amount of air that a fan can move. Larger bathrooms require fans with higher CFM ratings.

According to Fantech, the Home Ventilating Institute recommends 1 CFM per square foot in bathrooms up to 100 square feet. Larger bathrooms should be sized based on fixtures. All standard tubs, showers, and toilets add 50 CFM each to the the total. Large tubs and whirlpools require 100 CFM per fixture.

Visit SupplyHouse.com to find a large selection of bath fans from Fantech, Panasonic, Broan/Nutone, and Air King.
