High-Efficiency Boiler Installation for Radiant & Hydronic Heating

Once we understand your heating needs, we recommend the exact boiler capacity (measured in BTU output) your home requires. Our primary brands are Burnham, US Boiler, New Yorker, and Bradford White—all offer high-efficiency condensing boilers with excellent warranties and robust parts availability across Lancaster County. We explain AFUE ratings (Annual Fuel Utilization Efficiency) and the long-term operating cost difference between a 95%-AFUE condensing boiler and older 80%-AFUE models.

We design the complete hydronic system: where the boiler will sit, how supply and return piping will run, what size expansion tank is needed (critical for safety under pressure), which circulation pump will provide adequate flow without noise, where baseboard radiators or radiant loops will connect, and how the system will drain safely for winter shutdown or maintenance. We select the right pressure relief valve, low-water cutoff, and temperature/pressure gauges so the system operates within safe limits.

• Calculate exact boiler capacity (BTU output) needed for your home’s heating demand
• Select circulation pump sized for your system’s flow rate and pressure requirements
• Specify expansion tank volume to safely manage thermal expansion as water heats
• Design complete piping layout: supply main, return main, radiator branches or radiant zones
• Plan radiant tubing layout if installing underfloor heating (spacing, loops, manifold location)
• Specify baseboard radiator sizes and quantities if using that distribution method
• Select pressure relief valve, low-water cutoff, and temperature/pressure controls
• Identify any piping upgrades needed and plan installation sequence
• Review financing programs and research available rebates and incentives
• Provide written estimate with equipment specifications, labor, timeline, warranty, and total cost

Boiler installation in Lancaster County requires gas, plumbing, and sometimes electrical permits. We pull all necessary permits, coordinate with local building authorities and utility companies, and ensure inspections are scheduled at the right times. We notify you of any special preparation—clearing access to the boiler installation area, ensuring water and gas line access, protecting furnishings from construction dust—so installation proceeds smoothly.

• Pull required gas, plumbing, and HVAC permits from Lancaster County and local jurisdictions
• Coordinate inspection scheduling with local building officials
• Contact utility company if gas meter relocation or gas line work is needed
• Verify equipment delivery dates and schedule installation appointment
• Arrange safe disposal of your old boiler through responsible recycling partners
• Plan water system flush procedures and obtain any water treatment chemicals needed
• Notify neighbors if work may cause temporary service disruptions

Installation day begins with safe removal of your old boiler. We drain the system completely, disconnect the gas supply at the meter or tank, remove all electrical connections, and disconnect supply and return piping. Old boilers are hauled away same-day through our recycling partners. We protect your basement or utility room—laying drop cloths, containing debris, clearing pathways—and inspect the installation area for any structural issues the new boiler must accommodate.

• Safely drain the boiler and distribution system, disposing of water according to code
• Shut off gas supply and verify it’s isolated at the meter or tank
• Disconnect electrical power and test that no current flows to the old boiler
• Disconnect all supply and return piping connections
• Safely remove the old boiler using proper lifting techniques and equipment
• Clean up all debris and haul away old equipment same-day
• Inspect the installation area for structural issues, water damage, or clearance concerns before placing new boiler

We position the new boiler in its designated location—basement, utility room, or attic—ensuring adequate clearance for servicing, air intake, and vent routing as required by code. We connect the expansion tank, circulation pump, pressure relief valve, and all controls before connecting the boiler to the supply and return mains. Each connection is pressure-tested to confirm no leaks.

If radiators or radiant loops need upgrades or new installation to match the boiler’s output, we make those modifications and balance the system so every radiator receives adequate flow. Unbalanced systems overheat some rooms while leaving others cold.

• Position new boiler securely in its installation location with proper clearance for service access
• Install expansion tank sized for your system’s thermal expansion
• Connect circulation pump with proper inlet/outlet orientation for reliable flow
• Install pressure relief valve, low-water cutoff, and temperature/pressure gauges
• Pressure-test all connections to confirm no leaks before running water through system
• Connect supply and return piping from boiler to distribution system (radiators or radiant loops)
• Verify circulation pump moves water at correct flow rate through all radiators
• Balance radiator valves so each reaches setpoint temperature without overheating or underperforming

We connect the new boiler to your home’s gas supply using properly-sized pipe and approved connections. All gas lines are pressure-tested to ensure no leaks—gas leaks are hazards and must be detected early. We install a new gas shutoff valve at the boiler and verify that the safety controls—low gas pressure switch, high limit switch, and gas burner ignition system—are functioning correctly.

Gas combustion inside the boiler produces carbon monoxide (CO), which must be safely exhausted outside. We verify that the boiler’s draft safety controls operate correctly to ensure CO never backs up into your home.

• Connect boiler to gas supply with properly-sized pipe per code requirements
• Pressure-test all gas line connections using nitrogen gas to confirm no leaks
• Install gas shutoff valve and verify it operates freely
• Install and test safety controls: pressure switches, flame detection, burner ignition
• Perform combustion analysis on the boiler to confirm proper gas mixture and heat output
• Test boiler draft to confirm safe exhaust venting and no CO backup risk

Boiler electrical installation must meet local code and include proper circuit breakers, disconnect switches, wire sizing, and connections. We test all electrical connections for proper voltage and continuity, and verify that the thermostat communicates correctly with the boiler controls. We also install safety devices—high-limit switches that prevent dangerous overheating, low-water cutoffs that prevent dry-firing—and test their operation before powering up the system.

• Install electrical circuit breaker and disconnect switch per local code
• Run properly-sized wire and conduit from electrical panel to boiler
• Verify proper voltage (120V or 240V depending on boiler type) at all connections
• Test electrical continuity and grounding integrity
• Install and test safety control devices: high-limit switch, low-water cutoff, flame rollout protection
• Connect thermostat control wiring and verify communication with boiler controls
• Test all safety interlocks to confirm system shuts down safely if problems develop

Boilers require safe venting of combustion exhaust to the outside. We inspect the existing chimney for damage, blockages, or improper sizing and clean it thoroughly if suitable. If we’re installing a power-vent or direct-vent system, we run new venting pipes from the boiler to the exterior, ensuring proper slope and secure fastening. We test draft to confirm that boiler exhaust safely exits to the outside and does not back up into your home.

• Inspect existing chimney or plan new venting route for safe exhaust
• Install or connect boiler vent pipe with proper slope to prevent condensate pooling
• Secure all vent connections and inspect for leaks
• Perform draft test to confirm positive venting and no CO backup risk
• Test boiler draft safety controls to confirm reliable operation

Before we leave, the boiler is powered up, cycled through heating mode, and tested for proper operation. We measure boiler output temperature, confirm the circulation pump circulates water properly, verify the thermostat controls temperature accurately, and test all safety controls. We show you how to use the thermostat, explain water pressure maintenance, discuss seasonal maintenance, and walk you through the warranty so you understand coverage and exclusions.

You’ll receive complete documentation: boiler model number and serial number, warranty cards, installation completion certificate, gas and electrical inspection reports, system commissioning records documenting water chemistry, and our emergency contact information. Any questions during your first heating season are answered by the technician who installed the system.

• Perform system startup and confirm boiler powers up and cycles properly
• Measure boiler output temperature to verify proper heat output
• Verify thermostat communicates with boiler controls and adjusts temperature correctly
• Test circulation pump flow rate to confirm adequate water movement through all radiators
