Did you know? I've taken the time to research how these older central heating systems worked and found the #1 reason connected to problems with efficiency, water hammer noise and unbalanced operation, is improper service and maintenance. Whatever problems you are experiencing could be easily corrected with minor adjustments. I can provide you with a clear explanation and solutions for these problems. I'm currently working on a vacuum based update, that can be easily connected to any central steam system this system is able to mechanically remove the air from the steam piping, reducing the time it takes to fill the system so your heating faster, balancing the system and the distribution of heat throughout your home.
