NYC/NY state - seeking a demo site for a new type of vacuum system.

This is a continuation of the "Vapor heating system with naturally induced vacuum" thread – I have decided to start a new thread in order to reach more audiences.

A hundred year old single–pipe steam heating system was converted into a vacuum

system which has a naturally induced vacuum. The upgraded system includes an

original Ideal boiler and 6 cast iron radiators which heat an 1100 sq. ft

apartment; the system conversion of such an apartment would cost around $450,

excluding labor (please, see my previous posts for details).

Attached is a graph of the therms per day usage of a steam heating system

before and after the conversion into vacuum system. Savings are in the 9-16%

range. I would expect more savings for a bigger system (with uneven steam

distribution and more overheating).

Comparison is done for winter months with similar average temperatures (this

winter months - after conversion and 2009-2010 -before conversion). Occupation

and heating pattern of apartment didn’t change in last 10 years.

Therms usage is from NGRID bills, average monthly temperatures are from weather

station database.

 <span style="text-decoration:underline;">I’m looking for a house or a small/mid-size building with a single–pipe steam heating system in New York or the state of NY.</span> What I plan to do with this building is to convert the heating system into a vacuum system with a naturally induced vacuum and allow this system to be observed in order to prove the savings.  Plumbing and automation will be performed by a professional NYC company with a proven record in vacuum heating system implementation. 

Changes to the original plumbing will be minimal, most efforts – on system’s

leaks fixing.

<span style="text-decoration:underline;">This is upcoming NYSERDA research project and up to 80% of the conversion</span>

<span style="text-decoration:underline;">cost will be reimbursed to the owner of the building. </span>

Please let me know if you are interested.
