Case Study: Large 1930 colonial home Nutley NJ

For this job the challenge was to find out why an 11 year old steam boiler failed and rotted out.
Our approach was to do a complete system analysis, from piping, venting, properly measuring the connected radiation to be sure the new boiler was sized correctly.
After system analysis it was clear the boiler was oversized and the near boiler piping was way undersized, on top of which being plumbed in copper, a no no on steam systems. All main venting in the basement was upgraded. All radiators received new vents and the system was balanced to provide total comfort throughout the home.
