Types of Boilers We Install

We install a range of modern, reliable boilers to fit different homes and heating needs in Leominster, Fitchburg, and Central Massachusetts. Our team will assess your home and recommend the right system for efficiency and comfort.

Gas Boilers (Natural Gas)
  Ideal for many Massachusetts homes with gas service. Gas boilers offer reliable heat, fast response, and excellent efficiency when properly sized and installed.

Oil Boilers
  Common in older Central MA homes that don’t have natural gas. Modern oil boilers are much more efficient than older units and remain a good option where oil heating is the norm.

Combi (Combination) Boilers
  Compact systems that provide both space heating and on-demand domestic hot water. Great for smaller homes or when you want to eliminate a separate hot-water tank.

Condensing Boilers
  High-efficiency boilers that recover extra heat from exhaust gases. If you want the best fuel economy and lower heating bills, a condensing model is an excellent choice.

Electric Boilers
  A good solution where gas or oil isn’t available. Electric boilers are simple, quiet, and low-maintenance, though running costs depend on electricity rates.

Not sure which boiler is right for your home? Our licensed technicians will evaluate your house, insulation, and heating demands and recommend the most efficient, cost-effective option.

Our Installation Process

What to Expect

(Step-by-Step)

Below is a clear simple walkthrough of how a new boiler installation with Leominster Boiler & Heating typically goes. It’s written so you know the timeline, the steps we take, what we need from you, and how we handle the entire process start to finish.

What happens


  •  We visit your home, inspect your existing heating system, review fuel type (gas/oil/electric), measure rooms, check piping and venting, and discuss your comfort goals and budget.

Why it matters: Proper sizing and system selection prevent short-cycling, poor comfort, and higher bills.


You get: A written quote outlining equipment, labor, timeline, and any required permits.


We arrange a convenient install date most residential installs are scheduled within 1–3 weeks depending on parts and calendar.


 If a municipal permit or inspection is required, we handle permit submission for Leominster/Fitchburg and coordinate inspections. This may add a few days depending on local turnaround.


We confirm arrival window, parking/access instructions, and any homeowner concerns.


At this point we ask you to get your house ready for us, clear the working area around the boiler and the path to the installation location and to move any small items from nearby walls or benches.

Description Title

1. Removal & Rough-In


Old unit removal: Safely disconnect and remove the existing boiler, piping, and old flue components. We dispose of the old unit (ask about recycling options).


Site prep & rough plumbing: Install new fittings, base/stand if needed, and modify piping/fuel lines. If structural or flue changes are required, we complete the rough work.


Electrical & controls: Run wiring for the new controls, thermostat hookup, and zone integration if applicable.


2. Final Install, Start-Up & Testing


Connect system: Final plumbing, fuel, venting, condensate drains (for condensing boilers), and controls.


System fill & purge: Fill, bleed, and pressure-test the hydronic system.


Start-up & calibration: Fire the boiler, adjust combustion, set thermostats, and calibrate controls for efficiency and comfort.


Safety checks & testing: Verify combustion, ventilation, leak-free piping, and operation of safety devices.


3. Walk-through: We explain basic operation, thermostat settings, and maintenance tips.


Notes: Simple like-for-like swaps often finish in one full day. Complex installs (new venting, flue relocation, switching fuel types, or multi-zone upgrades) can take 2–3 days.
