Boiler Installation for Bath Homeowners
High-Efficiency Systems
Proper Sizing & Design
Clean Copper Piping
Bath sits in Sagadahoc County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for boiler installation gets a technician who already knows the local housing and codes, not a first-timer.
Aces Highlands installs high-efficiency boiler systems designed to keep your home warm through the toughest Maine winters. Every installation is properly sized, cleanly piped, and thoroughly tested before we leave.
We install oil, propane, and natural gas boilers from trusted manufacturers including Viessmann, Buderus, and Weil-McLain. Our installations feature clean copper piping, properly insulated lines, and professional workmanship that speaks for itself.
Every boiler installation starts with a heat loss calculation to determine the right size system for your home. An oversized boiler wastes fuel and short-cycles, while an undersized system cannot keep up in cold weather. We get the sizing right. Pair your new boiler with a radiant floor heating system for the ultimate in comfort.
We handle complete system installations including boiler placement, piping, zone controls, expansion tanks, and all necessary safety devices. Our work meets or exceeds all applicable codes and manufacturer specifications. Ask about our financing plans for new boiler installations.
Why Bath Calls Aces Highlands
- Based just outside Bath and out on Sagadahoc County calls every day
- Diagnostics come first, upsells do not — the invoice matches the quote
- Most requests land a visit within days, not the following month
- Licensed, insured, and background-checked; Google reviewers back up the work
Bath Homes and What They Need
Bath has the oldest housing stock among the Sagadahoc towns Aces serves, with a median build year of 1938 and 57.5 percent of homes dating before 1940 (66.5 percent before 1960). That history traces straight back to the city's shipbuilding boom, and it means downtown and the surrounding historic district carry plenty of original wiring and cast-iron plumbing. Exterior changes in the historic district need Planning Board review under the city's Land Use Code, so a heat pump installation here often starts with figuring out where the outdoor unit can go.
Heating and Cooling in Bath
About 47 percent of Bath households heat mainly with fuel oil, with bottled or tank propane at 20 percent and electricity at nearly 20 percent, and the city sits within Maine Natural Gas's service territory. With so much of the housing stock this old, a boiler repair call is just as likely to turn up a decades-old cast-iron boiler as a newer high-efficiency unit.
Getting to Know Bath
Bath was incorporated as a town in 1781 and chartered as a city in 1847, named after Bath, Somerset, England. Since 1743, roughly 5,000 vessels have been built along its Kennebec River waterfront, including the Wyoming, widely considered the largest wooden ship ever built, launched from the Percy & Small Shipyard.
Bath Iron Works, founded in 1884 by Thomas W. Hyde, has built hundreds of Navy vessels and given the city its 'City of Ships' nickname, one that still fits given how much of the local economy still runs through the shipyard. The Abenaki called the river itself 'Sagadahoc,' meaning the mouth of the big river, which is also where Sagadahoc County gets its name.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Bath gets treated. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. We show up, fix the actual problem, and let the work speak for itself.
How a Boiler Works
- Burner — ignites fuel to heat the exchanger
- Heat exchanger — heats the water circulating in the loop
- Circulator pump — pushes hot water through the loop
- Expansion tank — absorbs pressure as water heats and expands
- Baseboard loop — hot water out, cooler water returns

Boiler Installation: Sizing, Piping & the Details That Matter
A boiler replacement is one of the few HVAC jobs where reusing the existing piping layout without checking it can quietly undercut the new equipment's performance.

Codes & Permits for Boiler Installation in Bath

- Chimneys and vents serving fuel-fired appliances, including hydronic boilers, are governed by NFPA 211, the standard for chimneys, fireplaces, and vents. maine.gov
- State law requires a carbon monoxide detector in each area within or giving access to a bedroom wherever a fuel-burning heating appliance like a boiler serves a covered dwelling. mainelegislature.org
- Installing or servicing an oil-fired boiler in Maine requires a Maine Fuel Board Oil Burner Technician license (Apprentice, Journeyman, or Master), and apprentices must work under a licensed technician. maine.gov
How Aces Highlands Handles Boiler Installation in Bath
- Where Maine Natural Gas (MNG), a Unitil company serves the street in Bath, gas equipment is usually the simplest boiler installation option; elsewhere we quote oil, propane and heat-pump alternatives side by side.
- About 47% of Bath homes heat with heating oil today. Oil equipment is installed to NFPA 31, gas and propane to NFPA 54/58, and every vent or chimney tie-in to NFPA 211.
- We don't close out a boiler installation without confirming CO detectors are installed near sleeping areas, which Maine requires wherever the heat comes from burning fuel.

I've had three HVAC issues over the past two years. Each time I call, Elija or the office picks up the phone, and my problem is fixed in 24 hrs. Their solutions always feel correct and honest. I cannot recommend them more.

Elijah and Highlands Heating & AC were super helpful! Boiler failed over the weekend and Elijah was very responsive and helpful, getting us up and running right away. I would recommend him at HH&AC highly!

We highly recommend Highlands Heating & AC. They are extremely responsive, knowledgeable and do great work. Our boiler stopped working and Elijah was quick to respond after hours on a Friday. He installed a new boiler and heat pump hot water heater.

He was very friendly. He gave me an honest explanation on why I shouldn't recharge my A/C unit and what he suggested made much more sense. He really took care of everything. He is very professional, always called me with updates. 5 stars is not enough — I give this company 10 stars.

This team was called in by my property management company for where I rent. Elijah and his team were professional, clear speaking. Good communicators gave me the real deal. Didn't give any runaround. I trust them and want to use them for my own projects.

Boiler Installation FAQs
How long does a boiler last in Maine?
A well-maintained cast-iron boiler commonly runs 20–30 years; high-efficiency condensing boilers typically last 15–20. Annual maintenance is the biggest factor — a neglected boiler gives up years early, a serviced one keeps going.
How much does boiler replacement cost?
Most full residential replacements in Southern Maine land between $7,000 and $12,000 installed, depending on fuel type, efficiency class, and the piping and venting work involved. We provide a firm written quote before any work begins, and financing is available.
How long will I be without heat during the swap?
Most replacements are completed in one to two days, and we plan the changeover so your home is without heat for the shortest window possible — usually just part of one working day.
Should I convert from oil to propane or natural gas?
It depends on fuel availability at your address, your current equipment’s age, and long-term fuel pricing. Conversions unlock quiet, compact high-efficiency boilers, but they carry added venting and fuel-line costs. We install oil, propane, and gas systems, so our recommendation is not biased toward any one answer.
What boiler brands do you install?
We install trusted manufacturers including Viessmann, Buderus, and Weil-McLain, and we match the brand and model to your system design rather than pushing a single house brand.
