Lake Anna home features Uponor radiant heat and chilled water cooling

June 19, 2012 By

This new home on the shores of Lake Anna, Virginia, features radiant heat and chilled water cooling.

We designed and installed the mechanical system in this new home on the shores of Lake Anna, Virginia.  The house was designed by architect David Peabody, whom we’ve worked with on multiple projects over the last five years.

The project features Uponor radiant floor heating, two Lochinvar Knight boilers, DHW through an HTP stainless steel tank, chilled water cooling through two Unico chillers, tekmar and Taco controls, Nortec steam humidifiers and ventialtion through two Renewaire ERV’s.

Since this project is about a 1-1/2 hour drive from our shop, I designed redudancy into the mechanical system to minimize the chance of no-heat or no-cooling.

Registration opens for ACCA’s first Hydronics Roundtable

June 12, 2012 By

The first ACCA Radiant and Hydronics Council (RHC) Rountable will take place September 11 – 12, 2012, at the Providence Marriott Downtown in Providence, RI. Early bird registration is now open for the event, and attendees can save $100 by registering by August 1.

The Hydronics Roundtable is the only event that is created by contractors, for contractors, featuring many of the nation’s leading radiant and hydronics professionals. Whether you are a seasoned radiant veteran or new to the field, you won’t find a more useful, friendly, and engaging program anywhere else.
Kicking off the two day event will be Rich Trethewey, president of RST Thermal, who is best known for his service as the mechanical systems expert on the popular PBS show, This Old House, since 1979, and Ask This Old House since 2000. During his keynote address, Threthewey will talk about the future of radiant and hydronics contracting, the changes it faces, and the opportunities that contractors can capitalize on to grow their businesses.
There will also be 12 breakout sessions covering both advanced and basic topics running concurrently throughout the two days. Sessions include:
  • The Tube Installation Boogie with Bob “Hot Rod” Rohr of Caleffi North America
  • Distribution Efficiency: An Inherent Advantage with John Siegenthaler, P.E. of Appropriate Designs
  • Estimating Fuel & Electrical Consumption with John Barba of Taco Inc.
  • Mega-Homes and Light Commercial Parts 1 & 2 with Dan Foley of Foley Mechanical and Greg Jannone of William Jannone & Sons
  • Cost Estimating for Radiant Floor Heating with Bill Shady of Sustainable Design & Product Management
“This inaugural event is going to be packed with information from some of the best speakers in the industry, many of whom taught me radiant and hydronics and always know what’s on the cutting edge,” said Dan Foley, president of Foley Mechanical in Lorton, VA, and chairman of the RHC Advisory Committee. “The entire committee is excited to be providing so much quality information in one place to our peers. We look forward to seeing and networking with the many contractors that who work in the hydronics market segment and are moving the industry forward.”
Registration is open for this event at http://hydronicsroundtable.com/ or by calling 703-824-8856. Early bird registration, with a $100 discount, is available through July 31, 2012.
ACCA has secured a special rate of $169/night plus applicable fees and taxes at the Providence Marriott Downtown for Hydronics Roundtable attendees. This rate is only good through August 21, 2012 or until the block is full, whichever comes first. To make your reservation, call 866-807-2171 and mention ACCA, or visit www.hydronicsroundtable.com/hotel-info/ to book online.
Limited sponsorship opportunities are also available for the event; for display and sponsorship info, contact Tom Murphy at 703-824-8875 or tom.murphy@acca.org.

The ACCA is a non-profit association serving more than 60,000 professionals and 4,000 businesses in the HVACR community, who work together to promote professional contracting, energy efficiency, and healthy, comfortable indoor environments for all Americans.

Seymour Krieger House enjoys second generation of radiant along with complete mechanical update

April 3, 2012 By

This house, located in Bethesda, MD, was designed in the 1950s by internationally renowned modernist architect Marcel Breuer.  It is known as the Seymour Krieger House and is listed on the National Register of Historic Places.

The Seymour Krieger House currently is owned by an architect, and he wanted to restore the mechanical system while keeping the architectural integrity of the structure intact.

The house was originally heated by a radiant floor heating system.  The original boiler was still in place and operational, but the wrought iron radiant piping has corroded and was leaking in multiple locations.

We discussed multiple alternatives but in the end, the owner decided to go back with radiant floor heat.

The bluestone floor tiles were painstakingly numbered and removed.  The concrete overpour, along with the original wrought iron radiant tubing, was removed.

Old radiant pipe, torn out to make way for the new tubing.

The flagstones were carefully labeled so they could be returned to their original positions.

We installed the new Rehau PEX radiant tubing system, and a new concrete slab was poured.  The flagstones were carefully placed back in exactly their original positions.

We updated the entire mechanical system by installing a new Triangle-Tube boiler, HTP DHW tank, Viessmann solar heat and DHW system, and new Carrier high-efficiency AC system.

Four Viessmann flat panel solar collectors were mounted on the flat roof along with a Carrier 17 SEER AC unit.

We re-piped and re-controlled the radiant system to allow for multiple zones.  The Viessmann solar system will contribute to space heat when the DHW load is satisfied (see mechanical flow diagram and radiant floor heat plan).

The clients were a joy to work for and appreciated the hard work done by my crew on this difficult and challenging project.
