MODERN HYDRONIC HEATING

Unrivaled Radiant Warmth with Up to 96% AFUE Efficiency

If your old boiler is over 20 years old, it operates at roughly 60–70% efficiency — meaning 30 to 40 cents of every dollar spent on gas is wasted up the chimney.

Upgrading to a modern condensing boiler or wall-hung combi unit eliminates cold spots, provides whisper-quiet heat, and drastically lowers your winter utility bills while qualifying for local gas rebates.

  • Up to 96% AFUE gas efficiency — save 20–35% on winter heating
  • Combi boilers eliminate separate water heaters & free up basement space
  • Modulating gas burners automatically match outside temperatures
  • Qualifies for up to $1,000 in Peoples Gas & Columbia Gas rebates
  • Custom near-boiler piping engineered for quiet, even heat

PRECISION ENGINEERING

Our 6-Step Boiler Installation Process

Every hydronic boiler installation requires exact near-boiler pipe geometry, water chemistry protection, and digital combustion calibration.

01

Hydronic Heat Loss & EDR Sizing Audit

We perform a comprehensive thermal assessment. For hot water systems, we calculate room heat loss. For steam systems, we measure every cast-iron radiator to calculate total Equivalent Direct Radiation (EDR), ensuring perfect steam delivery without short-cycling.

02

System Selection & Utility Rebate Verification

We help you choose between standard cast-iron, high-efficiency modulating condensing (Mod-Con), or wall-hung combi boilers from Weil-McLain, Navien, and Burnham. We pre-qualify you for up to $1,000 in Peoples Gas or Columbia Gas rebates.

03

Safe Removal & Code-Compliant Disposal

Our team disconnects gas, water, and electrical connections, safely drains the existing hydronic system, and removes the heavy cast-iron boiler from your basement with complete respect for your property and floors.

04

Near-Boiler Piping & Zone Valve Upgrades

A boiler is only as good as its piping. We build clean black-iron headers for steam systems (to guarantee dry steam) or primary/secondary copper loops with isolation flanges, expansion tanks, and backflow preventers for hydronic systems.

05

Precision Venting & Gas Connection

We install dedicated PVC/polypropylene direct venting through an exterior wall for 95%+ high-efficiency units or install stainless steel chimney liners for atmospheric models. Gas lines are pressure-tested for absolute safety.

06

Combustion Analysis & Radiator Balancing

Using digital combustion analyzers, we calibrate the gas-to-air ratio for peak AFUE efficiency. We fill, purge all air pockets, bleed radiators, test low-water cutoffs, and walk you through system operation.

WHY CHOOSE US

Pittsburgh's Hydronic Installation Leaders

Master Pipefitters

Boiler piping requires exact header geometry and primary/secondary loops to prevent boiler thermal shock. We build clean, professional mechanical rooms.

EDR Steam Sizing

We measure all radiators before ordering steam boilers. Sizing steam boilers by square footage causes banging and boiler cracking. We calculate exact EDR.

Rebate Paperwork Handled

We complete and submit all utility rebate paperwork with Peoples Gas and Columbia Gas so you get your rebate check without hassle.

10-Year Workmanship Warranty

In addition to manufacturer heat exchanger warranties up to 20 years, our near-boiler piping and installation labor is backed for 10 full years.

FAQ

Boiler Installation Questions

How much does a new boiler cost to install in Pittsburgh?
A standard cast-iron residential gas boiler installation typically costs $6,500 to $9,500. High-efficiency condensing (Mod-Con) boilers or wall-hung combi units range from $8,500 to $14,000+ depending on home size, near-boiler piping, and venting configuration. Rebates from Peoples Gas or Columbia Gas can save up to $1,000.
How long does a boiler installation take?
A standard cast-iron or high-efficiency boiler installation typically takes 1 to 2 full days. We isolate the work area, disconnect and remove the old unit, build the new near-boiler piping headers, connect gas and venting, and test all radiator zones.
What is the difference between a hot water boiler and a steam boiler?
A hot water boiler pumps heated water through pipes to radiators or baseboards under closed-loop pressure (12–20 PSI). A steam boiler heats water into steam, which expands and travels up through pipes at low pressure (0.5–2 PSI) to cast-iron radiators, condensing back into water. They require completely different sizing and near-boiler piping.
Can I replace my boiler with a combi boiler to save space?
Yes. Combination ('combi') boilers are wall-mounted and heat both your home radiators and your domestic hot water on demand. This frees up significant floor space in your basement by eliminating your old standalone water heater tank.
Do you install chimney liners with new boilers?
If you install a standard-efficiency atmospheric boiler venting into a masonry chimney, a new stainless steel chimney liner is typically required by Pittsburgh building code to prevent corrosive condensation from deteriorating your chimney mortar.
