Tankless Water Heaters for Brunswick Homeowners

When Brunswick homeowners need tankless water heaters, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Brunswick in Cumberland County — so we respond quickly and know the homes, the weather, and the codes in your area.
Tankless water heaters heat water on demand, providing endless hot water while saving space and energy. Aces Highlands installs propane and electric tankless systems properly sized for your household needs.
A tankless water heater heats water only when you need it, eliminating the standby energy loss of keeping a tank of water hot around the clock. This can reduce your water heating costs by 24-34% depending on your usage.
We install tankless units from trusted brands and ensure proper gas line sizing, venting, and water flow for optimal performance. Electric tankless models may require an electrical panel upgrade to support the higher amperage draw. Not every home is a good candidate for tankless — we evaluate your situation honestly and recommend the best option.
Tankless water heaters last 20+ years with proper maintenance, compared to 10-12 years for tank models. While the upfront cost is higher, the longer lifespan and energy savings make tankless a smart long-term investment for many homeowners. We offer financing to help spread the cost over time.

Brunswick Homes and What They Need
Brunswick has the most mixed housing in this part of the coast. Census estimates count about 9,500 homes with a median build year of 1982; roughly 20 percent were built before 1940 and nearly half before 1980. Only about half are detached single-family houses, since the town also has apartments, college housing and mobile homes, about one in eight units. The Federal and Victorian streets near Bowdoin and downtown are the oldest, while the McKeen Street neighbourhood, built for Navy families in the 1950s and 60s, was sold off as some 230 homes after the air station closed. Each era brings its own wiring: knob-and-tube and fuse boxes can still turn up in the old core, and base houses carry services sized for 1950s loads. A panel upgrade in a Brunswick home is often needed before adding heat pumps or an EV charger.
Water Supply and Drains in Brunswick
Most of Brunswick's developed area is on public water and sewer. The Brunswick and Topsham Water District, incorporated in 1903, pumps from sand-and-gravel aquifer wells and has long treated some wells to remove naturally occurring iron and manganese. Part of its Jordan Avenue well field has been kept offline and treated because of PFAS contamination linked to a storm drain on the former naval air station. The Brunswick Sewer District runs the treatment plant on the Androscoggin with roughly 85 miles of pipe and nearly 40 pump stations; the farther rural roads rely on wells and septic. In the old downtown, cast-iron stacks and aging clay laterals are common, and professional drain cleaning is often the first step before a camera inspection.

Getting to Know Brunswick
Brunswick is home to Bowdoin College, chartered in 1794 as Maine's first college. Harriet Beecher Stowe wrote "Uncle Tom's Cabin" while living on Federal Street in 1851, and Joshua Chamberlain — the Bowdoin professor turned Civil War hero who accepted the Confederate infantry's surrender at Appomattox — later served as Maine's governor and Bowdoin's president. The former Naval Air Station is now Brunswick Landing, one of Maine's largest business and technology campuses.
Brunswick's Federal-era and Victorian homes around the college are beautiful — and demanding. Panel upgrades, careful rewiring, and heating systems that respect historic construction are everyday work for our crew here.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Brunswick — not a national franchise. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. We show up, fix the actual problem, and let the work speak for itself.
How a Tankless Water Heater Works
- Flow sensor — detects water flow and triggers ignition
- Burner — fires on demand, no standby tank
- Heat exchanger — heats the water as it passes through
- Hot water out — instantly, only when it's needed
- Compact — mounts on the wall, saves floor space

Tankless Water Heaters: Sizing by Flow Rate, Not Gallons
A tankless water heater is sized completely differently from a tank, and misunderstanding that is the most common reason a homeowner ends up disappointed with one.

In Brunswick, plumbing permits come from the Local Plumbing Inspector at the Planning & Codes Office, Town of Brunswick Dept. of Planning and Development (85 Union Street, Brunswick, ME 04011, 207-725-6660). With 21,756 residents, Brunswick is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The town contains multiple National Register historic districts (e.g., Brunswick Commercial, Federal Street, Lincoln Street), where exterior/mechanical work can face added design review (Wikipedia).
- Replacing or installing a water heater is plumbing work that falls under the town's Local Plumbing Inspector permitting and inspection process. mainelegislature.org
- Maine's 2021 energy code (IECC, part of MUBEC) requires insulation with an R-value of at least R-3 on 3/4-inch and larger hot-water piping inside conditioned space, and on recirculation piping, piping outside conditioned space, and buried piping. maine.gov

How Aces Highlands Handles Tankless Water Heaters in Brunswick
- Most Brunswick homes are on Brunswick & Topsham Water District water from sand-and-gravel aquifer wells; on a private well, we check the pressure tank and water quality alongside the tankless water heaters.
- Where Maine Natural Gas Corporation has a main nearby, gas is usually the lowest-cost tankless water heaters option in Brunswick; off the main, propane, electric and heat-pump units all work.
- We permit the replacement at the Planning & Codes Office, Town of Brunswick Dept. of Planning and Development, route the T&P relief valve to a code-compliant discharge, and handle gas hookups under our Fuel Board license.

Tankless Water Heaters FAQs
Does a tankless water heater really provide endless hot water?
Yes, within its flow capacity. A properly sized unit will run a shower indefinitely without going cold. The limit is simultaneous use — run three showers and a dishwasher at once and you can exceed its flow rate. That is why honest sizing for your household matters more than the brand.
How much does tankless water heater installation cost?
Nationally, installed costs typically run $2,500-$5,500 depending on fuel type, venting, and whether gas lines need upsizing — higher than a tank swap. The offset is a 20+ year lifespan and lower operating costs. We quote your exact price in writing before any work begins.
How long do tankless water heaters last?
Twenty years or more with annual descaling and basic care — roughly twice the life of a tank water heater. The heat exchanger is the key component, and keeping it free of scale is what gets you the full lifespan.
Does Maine’s cold groundwater affect tankless performance?
Yes, and it is the most important local factor. Winter inlet water in Maine can be 30+ degrees colder than in southern states, which reduces a unit’s effective flow rate. We size for Maine winter conditions so your system performs in January, not just on paper.
Will you talk me out of tankless if it is wrong for my home?
Yes — and we do it regularly. As a local company with no sales commissions, we have no reason to push the more expensive option. If your usage, fuel situation, or budget points to a quality tank heater instead, that is exactly what we will recommend.
