Taco's New 0015 3-Speed Family of Circulators

Taco is pleased to introduce its new "0015" family of circulators. The 0015 is an all-new family platform using single speed , 3-speed and variable speed motor options for a wide range of Hydronic, Radiant and Solar Thermal applications.

Stainless Steel casing option is now available for use on Domestic Hot Water recirculation (DHWR) and other open fresh water applications. The Stainless Steel 0015 3-Speed version is a direct replacement for the Grundfos UPS 15-35SF and UPS15-55SF.

Both casing materials come in standard in-line or rotated flange options and include an Integral Flow Check (IFC) as standard.

With the addition of Taco's Variable Speed control options, the 0015 can also be adapted to many other applications including 0015-VDT for maintaining a constant system Delta T, 0015-VR (Outdoor Reset) or 0015-VS (SetPoint) for Radiant injection mixing and 0015-VT for Solar Thermal systems.

The new 0015 circulators are available now! Look for the new box to identify the updated Taco circulators at a wholesaler near you!

New 0015 model numbers are:

• 0015-MSF2-IFC cast iron, standard in-line flange
• 0015-MSF2-1IFC cast iron, rotated flange
• 0015-MSSF2-IFC stainless steel, standard in-line flange
• 0015-MSSF2-1IFC stainless steel, rotated flange

Introducing The 3500 Series From Chicago Faucets

Chicago Faucets, a manufacturer of commercial faucets, introduces its new 3500 Series water conserving metering faucets. Made of ECAST brass, the 3500 Series provides a modern look and water savings.

The Chicago Faucets 3500 Series saves water with a 0.5 GPM (1.9 L/min) outlet. The self-closing MVP metering cartridge provides precise water flow and shuts off automatically for even greater water savings. The time-tested MVP mechanism is easy to adjust, and spare parts are readily available for quick change-outs, reducing downtime and lowering maintenance costs.

A solid ECAST brass, chrome-plated body provides durability while meeting local requirements for the reduction of lead in plumbing fixtures. Pre-installed, flexible, stainless steel hoses connect to standard water supplies. Internal temperature control is accessible above the deck for easy adjustment.

The 3500 Series fits almost any application. Get the brochure here.

Installing Radiant Under Hardwood

Hardwood floors can be used over a hydronic heating system if extra time and care is used during the installation process. Wood floors are what we call hydroscopic. That means the wood reacts to water, in much the same way a sponge does. If the wood is dry and goes into a wet environment, then the wood floor will adsorb moister and expand. Likewise, if the wood is too "wet" and is installed into a dry environment, it will dry and shrink.

Wood floors continuously move, just like the door jams in your home. In the summer they expand due to the increased humidity in the air and become harder to shut. In the winter the humidity is typically lower, and the doors shrink, becoming easier to close.

Wood floors will also experience this seasonal change in dimensions. However, there are some "tricks to the trade" that will help minimize these swings. Use a wood that is kiln dried. This helps to ensure the wood's moisture content is the same on the inside as it is on the outside.

1. Try to use a wood that is no wider than 3" to 3.5" in width. The narrower the strip, the less movement it can induce.
2. A quarter-sawn wood is better than a plane-sawn wood. Plane sawn woods tend to "grow" or expand in width, while a quarter-sawn wood will tend to expand more in thickness. This helps reduce visual cracking and gapping.
3. The wood should be around 7% - 10% in moisture content. This may require an acclimation period in order for the wood to reach this level. Sometimes, it is best to have the radiant system installed before the wood. This will help accelerate the acclimation process.
4. The wood floor should not be higher than 4% in moisture content than the floor it is being installed onto. This will allow for the subfloor and hardwood floor to move and react as a single unit. Otherwise, moisture maybe able to travel from layer to layer.
