Yes, Harvey is a true professional.  I am very fortunate to have him on my team.

Hi Frank

Hi Frank,

Yes, it has been awhile.  I have been busy on some big projects and I just  started a new one on the Eastern Shore.

How about lunch sometime in August?  G&M or Fells Point?  I will bring Brian, Poppy and Harvey.

I had seen this detail in books but never on a jobsite.  When Brian removed the plugs, he found that the water traps were full of crud a corrosion.  He flushed them out real good and replaced the plugs.  This, along with some bad traps and not enough "A" dimension were the primary cause of the water hammer.

Brian Golden, Harvey Youker and Fred Johnson have been busy this week installing a Burnham Independence steam boiler, replacing all the steam traps and installing a new water heater.

In addition, they had to relocate the gas pipe and water lines to accommodate a basement remodel. 

Steam Change-Out

@ July 16, 2014 9:25 PM in Steam Change-Out

This is one I looked at a month ago a block north of Glover Park in DC.  It is an old Burnham Series 4 that is about 25 years old.  It is connected to a two-pipe system with cast iron radiators and steam traps in a 1920's vintage rowhouse. 
 Most of the traps were original. The client complained of knocking and water hammer in addition to high fuel bills and reliability issues.

I got it direct from the manufacturer.

@ April 7, 2014 5:59 PM in Got my Sorbox today.

We finally got our Sorbox installed and operational.  We were waiting for the correct adapter fittings.  Hot Rod hooked us up with 1" PP adapters that did the trick.

This project in Frederick, MD was installed by my lead tech, Harvey.  The existing Rehau radiant system was installed in a concrete slab but the system had been abandoned for six+ years as a large renovation was put on hold. We are in the process of restoring the radiant system along with an entire mechanical upgrade/renovation. 
The tubing had frozen and split in multiple locations and was open to the atmosphere.  It was full of sediment , grit and biological contaminants.  Even after flushing with water and compressed air, "gunk" was still coming out of the system.

It will be interesting to see how the Sorbox will perform.  Harvey piped it on the return with a bypass that includes a 10-turn balance valve allowing for precise control of the amount of flow through the Sorbox.

ACCA - National Capital Chapter is hosting a John Siegenthaler seminar on October 3.  The title of the seminar is The Latest Trends and Technology for Hydronic Heating and Cooling.  The seminar is sponsored by Triangle Tube and will be held at Thos Somerville Co. Chantilly branch.  A flyer is attached.

Course Description:

A one-day course, taught by an expert in the field:
Hydraulic Separation
beyond primary / secondary pumping
shows how to achieve all the benefits of primary / secondary piping, with simpler, low cost approaches
Distribution efficiency & low power pumping
this topic proves that, and shows ways to significantly lower the parasitic operating cost of hyrdonics, especially in comparison to forces air heat delivery
Air-to water heat pumps
discuss how to operate and shows several ways to connect them with contemporary hydronic distribution systems
Small scaled chilled water cooling
you will learn several novel approaches using the latest hydronic design techniques and hardware options
Low mass/low temperature distribution systems
examples of hydronic heating meeting the needs of low energy use buildings
Instantaneous DHW using renewables + electricity
the methods discussed produce heated water faster than gas-fired tankless heaters, and are simple to install and maintain.

Hope to see you there!

For the Climatherm, we use a combination of Hilti strut and trapeze hangers.  The pipe is fairly stiff but will require more support than copper or steel.

Thank you for thinking of me.  Norfolk is about 3 hours away and too far for me.  I would recommend Gary Hayden @ Premier Comfort:

Hi Tim,

Looking forward to catching up with you in Providence.  I get in Monday evening.  Who else is going to be there?

Looking forward to catching up with everyone in September.  Sgn up now because it is looking like this is going to sell out as space is limted.  - DF

Hydronics Roundtable Event

@ July 31, 2012 5:52 PM in Hydronics Roundtable Event

ACCA-RHC (Radiant & Hydronics Council) is holding its fall conference in Providence, RI September 11 & 12.  Here is a link to the program:

We have a great line-up of speakers including Hot Rod, Robert Bean, Siggy, John Barba, John Abularrage, Bill Shady, Greg Jannone, Jeff Persons, and Brian Stack.  You won't find as talented a group of speakers in one place anywhere else. 

Richard Trethewey is scheduled to give the keynote address.  As a pioneer of modern radiant floor heat in North America, Rich has a unique perspective on the market.  He will candidly share his thoughts and leave you thinking.

The conference is conveniently located at the Providence Marriott.  I hope to see plenty of Wallies there.
