When it's time to replace your aging boiler or install a new hydronic heating system, Northwoods Heating LLC delivers the expert craftsmanship and honest guidance northern New Hampshire homeowners deserve. Our certified technicians specialize exclusively in oil boiler installation, bringing over two decades of focused expertise to every project.
We understand that a new boiler is a significant investment—and in our harsh New Hampshire winters, it's one you can't afford to get wrong. That's why we take the time to properly size your system, evaluate your existing piping and radiators, and recommend the most efficient options for your home. From selecting the right equipment to meticulous installation and startup, we're with you every step of the way.
Most oil boilers last 15–25 years. If yours is approaching or past this range, it's wise to consider replacement before it fails during the coldest stretch of winter.
If you're calling for boiler repairs multiple times per season, those costs can quickly exceed the value of your aging system. A new, efficient boiler often pays for itself in fuel savings and avoided breakdowns.
Older boilers lose efficiency over time. If your oil consumption has increased without a change in usage habits, a new high-efficiency boiler could significantly reduce your fuel costs.
Some rooms too hot, others cold? Your boiler may be losing pressure or struggling to distribute hot water properly—a sign it's wearing out or was never sized correctly for your home.
Banging, kettling, gurgling, or visible leaks around your boiler are warning signs of serious mechanical issues. These problems often indicate a system that's nearing the end of its useful life.
A healthy oil burner flame should burn cleanly. Excessive soot, a yellow flame, or visible smoke indicate incomplete combustion—a potential safety hazard that warrants immediate attention.
If your boiler constantly loses pressure or requires repeated refilling, there's likely an internal leak or expansion tank failure that may not be worth repairing in an older system.
Adding insulation, replacing radiators, or expanding your living space? Now is the ideal time to reassess your heating needs and upgrade to a properly sized, modern boiler system.
Step 1: Free Consultation & System Assessment
We start by evaluating your home's heating needs, existing boiler and piping, and your comfort goals. We'll assess your radiators or baseboard system, discuss your budget, and help you select the right boiler for your home—no pressure, just honest guidance from a local heating expert.
Step 2: Detailed Proposal & Scheduling
You'll receive a clear, written proposal outlining the work, equipment specifications, timeline, and cost. Once approved, we'll schedule your installation at a time that works for you, typically within 1–2 weeks.

Our certified technicians arrive on time and work efficiently to minimize disruption to your home. We handle all aspects of the installation including removing your old boiler, installing the new system, connecting fuel lines and hydronic piping, running all electrical and control wiring, setting up the expansion tank and pressure relief valve, and ensuring proper venting and code compliance.
Step 4: Testing, Balancing & Walkthrough

Most residential oil boiler installations are completed in one day, typically 6–8 hours depending on the complexity of your piping and home layout. We'll provide a specific timeline during your consultation. Our goal is to have you back to full heat as quickly as possible.
Boiler installation costs vary based on system size, efficiency rating, and your home's existing piping configuration. Most residential installations in northern NH range from $5,000 to $10,000 including equipment, labor, and permits. We provide transparent, written quotes with no hidden fees.
We perform a professional heat load calculation that accounts for your home's square footage, insulation levels, window quality, number of heating zones, and northern New Hampshire's climate. Proper sizing is critical—an oversized boiler short-cycles and wastes fuel, while an undersized one can't keep up on the coldest days.
We install quality oil boilers from trusted manufacturers known for reliability and efficiency in northern climates. During your consultation, we'll recommend specific models that fit your needs and budget. We only recommend equipment we'd install in our own homes.
Yes, removal of your existing boiler and proper disposal is included in our installation service. We'll also clean up completely before we leave—you won't even know we were there except for your new, efficient heating system.
We recommend annual maintenance, ideally in early fall before heating season begins. Regular tune-ups keep your warranty valid, maintain peak efficiency, prevent breakdowns, and extend your boiler's lifespan. We'll send you a reminder each year.
