Heat Load Software

I've been using Slant Fin's Heat Loss Explorer for years, in addition to an Excel spreadsheet that I put together based on John Siegenthaler's formula in "Modern Hydronic Heating".

I was recommended to Wrightsoft's Manual J software. I took a look at it. . . it seems very powerful, and worth the price, but it has a heavy emphasis towards HVAC. Furnaces, CFM, etc.

What software are you using?

Looking for a place to hang my license (NYC)

@ April 26, 2010 2:19 PM in Looking for a place to hang my license (NYC)

I have been found qualified to hold the NYC Master
Oil Burning Equipment Installer's license. I am in the process of
activating it and need to hang the actual plaque at a DOB approved
business location. I am in the start up phase of my corporation and do
not have the capital to rent a commercial shop location.




If you have an existing Plumbing/Heating or Fire Suppression license,
and would like to have access to an Oil Burning Equipment License,
perhaps we can work out a deal whereby I establish a business office at
your location, and agree to include your corporation on my tag,
allowing you to seek work that would fall under the purview of this
license.

Trust me the the supply and return water are being taken from opposite sections of the boiler.  This loop will have NO problem getting heat into it.

Sorry I don't want to give away the whole thing. . .

But I can tell you that I took the design almost directly from Dan's "How Come?" book of hydronics. 

It's a great book and well worth the purchase price.

Use a Honeywell R845A with dry contacts. . . NOT a Honeywell RA89A switching relay, which is commonly available, but only has one set of switching contacts.

The aquastat gets wired in the same way as a hydronic boiler.  When the basement thermostat calls for heat, the 845 activates the pump, and sends a LV signal to the boiler to fire.  The aquastat is set in series on the boiler fire, letting the boiler run up to about 200 degrees F, then switching off on limit.

However, the pump remains running for as long as the thermostat calls.

Because the basement zone controls are run in parallel to the standard boiler control wiring, the basement and steam settings are effectively isolated from each other.

That little manifold has solved a lot of problems for me.

Just wanted to share some photos of a neat Weil Mclain steam boiler replacement I did recently. 

This is an EG-35.  Notice the full sized steam header, with stress elbows.  Compared to the old American Standard that was in its place, this thing was whisper quiet even on first startup.  I insulated after I took the photos.

If you take a look at the second shot, you'll see a condensate hot water loop manifold that I installed into the mud leg, in preparation for a future connection.  The homeowner anticipates building a family room in his basement, and I left all the necessary instructions and fittings for him to just hook up his baseboard and fill the system.

Anyway just wanted to show off a little and share with you how I do things.
Thanks
