MODERN HEATING INSTALLATION.

Typical Problems We Resolve in Heater & Boiler Installation.
New York residential and commercial properties require specialized mechanical diagnostics. Here are the most common challenges our licensed master technicians handle every day.
Old Cast-Iron Boilers Operating at Under 65% Efficiency
Antique boilers send more than a third of your expensive natural gas straight out the chimney flue.
Modern modulating condensing boilers (up to 96% AFUE) that extract every ounce of heat from combustion.
Bulky Equipment Consuming Entire Basements
Old atmospheric tanks and cast iron sections occupy valuable living or storage space.
Compact wall-hung units (like Navien combi-boilers) that free up dozens of square feet while producing endless domestic hot water.
Cracked Cast Iron Sections Leaking Water
Thermal shock and sediment buildup eventually crack thick cast iron blocks, making repairs impossible.
Modern dual stainless steel heat exchangers designed for high thermal durability and longevity.
Unbalanced Heat Delivery Across Multi-Story Properties
Old single-pipe steam systems leave lower floors roasting while upper-floor tenants freeze.
Conversion to modern multi-zone hydronic manifolds with dedicated circulating pumps for each floor.
NYC Department of Buildings Permitting Violations
Unlicensed handymen replacing gas boilers without NYC DOB work permits risk shutoffs and liens.
Every installation is signed and sealed by an active NYC Licensed Master Plumber with full city sign-offs.
Chimney Relining Requirements for Modern High-Efficiency
Condensing boilers produce acidic exhaust that will destroy old brick chimney flues.
Direct-vent PVC/polypropylene sidewall venting or certified stainless steel chimney relining.

Frequently Asked Questions
How long does a boiler replacement take in NYC?
A typical residential boiler installation takes 1 to 2 days. In winter emergency situations, our team works continuously to restore heat to your property on day one.
What is a 'combi-boiler' and should I get one?
A combi-boiler (combination boiler) is a single, wall-mounted unit that heats both your home radiators and provides endless domestic hot water on demand. It completely eliminates the need for a separate bulky water heater tank.
Are your boiler installations permitted with the NYC DOB?
Yes. All boiler and gas work in New York City legally requires an NYC DOB Licensed Master Plumber. Agape pulls all required work permits, coordinates city inspections, and delivers official sign-offs.
How much can I expect to save on gas bills with a high-efficiency boiler?
Upgrading from an old 60–65% AFUE boiler to a 95%+ modulating condensing unit typically reduces natural gas consumption by 25% to 35% each winter.
