How long does boiler installation take?

Most like-for-like replacements are completed in a day. New piping, zoning, or venting changes can add time.

Condensing vs. standard boiler—what’s better?

Condensing (high-efficiency) boilers are most efficient with low return water temps (radiant, large radiators). Standard cast-iron units suit higher-temp baseboard loops. We size and recommend based on your emitters.

Combi boiler or indirect water heater?

Combi units save space and deliver on-demand hot water; an indirect tank offers strong recovery and longevity. We’ll recommend based on usage and space.

Do I need a chimney liner or PVC venting?

Standard boilers may require a lined chimney; condensing models use sealed PVC/PP venting. We handle venting to code either way.

Boiler Installation

Even, quiet heat starts with a boiler that’s sized to your home and piped the right way. We install high-efficiency condensing and standard cast-iron boilers with proper venting, zoning, and controls so baseboard, radiators, or radiant floors run smoothly all winter.

Which Boiler Is Right for Your Home?

Condensing (modulating) boilers. Highest efficiency at lower water temps; ideal for radiant floors and oversized cast-iron radiators. Outdoor reset control matches output to the weather for comfort and savings.

Standard cast-iron boilers. Durable and proven for higher-temperature baseboard loops. Simple controls and long service life when maintained.

Combi vs. boiler + indirect tank. Combi units save space and offer on-demand hot water. Indirect tanks pair with a boiler for excellent hot-water recovery and longevity.

Fuel, venting, and codes. We size gas piping, set regulators, and provide lined chimneys (standard) or sealed PVC/PP venting (condensing) to meet local code.

Hydronic Design That Matters

Primary/secondary piping or a hydraulic separator to prevent flow conflicts and protect the boiler.

Circulators or zone valves selected for the loop length and head; delta-T control where appropriate.

Air/dirt separation, expansion tank sizing, and proper fill/pressure reducing valve setup.

Mixing strategies for radiant floors vs. baseboard, plus domestic hot water priority control.

Installation Day — Step by Step

Protect floors and remove old equipment; verify gas, venting, and electrical.
Set and level the boiler; install venting (lined chimney or sealed PVC/PP).
Pipe primary/secondary or low-loss header; add circulators/zone valves and isolation valves.
Install expansion tank, air separator, backflow preventer, PRV, and relief valve.
Flush, purge air, pressure test; set system pressure.
Wire controls, thermostats, and outdoor reset; integrate DHW (combi or indirect).
Commission: combustion analysis, gas pressure, purge verification, and safety checks.

Controls & Commissioning

We set your outdoor reset curve, verify supply/return temps, confirm pump sizing/flow, and document combustion analysis. You’ll get a startup report and guidance on routine care (bleeding radiators, filter/strainer checks, and annual service).
