Boiler Installation & Replacement in New Jersey
Replacing a boiler is a specialized job, and the difference between a system that runs quietly for 25 years and one that short-cycles and leaks comes down to the installer. Heating Cooling NJ installs steam and hot water boilers in homes throughout New Jersey, from traditional cast-iron units to wall-hung condensing boilers that cut fuel use dramatically.
Every boiler project begins with a free estimate, a heat loss calculation and an inspection of your existing piping, radiators and chimney.
Boiler Types We Install
Cast-iron gas boilers remain a reliable, long-lived choice for homes with chimney venting. High-efficiency condensing boilers reach 95 percent AFUE, vent through PVC and modulate output to match the load. Combination boilers provide both heating and domestic hot water from one compact unit, which frees up basement space and eliminates a separate water heater. Steam boilers for radiator systems and oil boilers for homes without gas service round out the options. We install Weil-McLain, Burnham, Navien, Lochinvar, Bosch, Viessmann, Peerless and more.
Sizing and System Design
Oversized boilers are the most common mistake we see. We calculate the actual heat loss of the house, measure the connected radiation, and size the boiler accordingly. For hydronic systems we evaluate zoning, circulator sizing, expansion tank capacity and whether outdoor reset or an indirect water heater makes sense. For steam we measure the radiator EDR and ensure proper near-boiler piping so the system makes dry steam.
Installation Day
We drain and remove the old boiler, update near-boiler piping, install new isolation valves, air separation and expansion tank, set the new boiler to code with proper clearances, run new venting and condensate neutralization for condensing models, install gas piping and controls, fill and purge the system, and fire test the boiler while verifying combustion, pressure and temperature. Most replacements take one to two days, and we handle the permit and inspection.
Efficiency and Rebates
Upgrading from an old atmospheric boiler to a condensing model can reduce heating fuel use substantially, and high-efficiency boilers often qualify for New Jersey Clean Energy Program and utility rebates. Combining the boiler with an indirect water heater improves hot water efficiency as well.

How long does a boiler last?
Cast-iron boilers often last 25 to 35 years. Condensing boilers typically last 15 to 20 years with annual maintenance.

Converting is a large project. In most cases a properly installed new steam boiler is the better value. We will advise based on your home.
What is a combi boiler?
A combi boiler supplies both space heating and on-demand domestic hot water from one unit, which saves space and energy.
Can you convert my oil boiler to gas?
