Tankless Water Heaters for Auburn Homeowners
Endless Hot Water
Space-Saving Design
20+ Year Lifespan
Auburn homeowners call Aces Highlands for tankless water heaters because we are close by, based at 508 Riverside St Unit 1 in Portland, and out on Androscoggin County roads every day — we know this area's housing, weather and permit process cold.
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.

- Based just outside Auburn and out on Androscoggin County calls every day
- A straight diagnosis and a clear price before we touch anything — no upsell
- A short wait for a truck, not a long one — most jobs move fast
- Fully licensed, fully insured, and reviewed by real customers on Google
Auburn Homes and What They Need
Auburn's median home was built in 1954, with 38 percent of housing dating before 1940 and 57 percent before 1960 -- slightly older on average than Lewiston's stock, concentrated in the shoe- and mill-era neighborhoods that grew up after the city's 1848 rail connection went in. That vintage of housing is exactly where rewiring work tends to turn up knob-and-tube remnants and undersized panels.
Water Supply and Drains in Auburn
The Auburn Water District draws from Lake Auburn and supplies both Auburn and Lewiston, with the city coordinating on development near the source through the Lake Auburn Watershed Commission. Wastewater goes to the same joint Lewiston-Auburn regional treatment authority that handles Lewiston's flow. On older Auburn properties, that shared infrastructure is worth knowing before a sewer line repair traces back to the main.
Getting to Know Auburn
Auburn once had one of the largest shoe industries in the country -- by 1917 the city's factories were turning out roughly 75 percent of the world's supply of white canvas shoes, before the industry faded after World War II. That manufacturing boom is a big part of why Auburn's older neighborhoods look the way they do today.
Auburn sits across the Androscoggin River from Lewiston, and the two cities share more than a border: they draw water together through the Auburn Water District, and the Little Androscoggin River cuts through Auburn as well. Auburn also runs its own municipal Electrical Department, which both maintains the city's traffic signals and streetlights and handles the city's electrical code inspections.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Auburn under its own name. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. That is how we keep customers calling back, one honest job at a time.
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.

Codes & Permits for Tankless Water Heaters in Auburn
In Auburn, plumbing permits come from the Local Plumbing Inspector at the Planning, Permitting & Code, City of Auburn (60 Court Street, Auburn, ME 04210 (Auburn City Hall), (207) 333-6600). With 24,061 residents, Auburn is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Auburn grew as a mill town after the railroad arrived in 1848, powered by falls on the Androscoggin and Little Androscoggin Rivers; its shoe-manufacturing industry once produced a majority of the world's white canvas shoes (1917).
- 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
- A propane or natural gas-fired water heater installation or connection requires a Maine Fuel Board Propane and Natural Gas Technician license. mainelegislature.org
- Maine's adopted plumbing code (2021 Uniform Plumbing Code) requires every water heater's potable-water connections and temperature/pressure relief valve to meet UPC installation requirements, including a proper gravity discharge line. up.codes
- Every Maine municipality must annually appoint at least one Local Plumbing Inspector (LPI), who does not have to live in that town, to issue plumbing permits and enforce the state's plumbing rules and Subsurface Wastewater Disposal (septic) rules locally. mainelegislature.org

We have called Samuel for our electrical needs over the last few years and have always been impressed with professional and courteous attitude — installing extra outlets, installing new lights and ceiling fans, our whole house generator, charger for the electric car, even the hot tub!!! His price was fair, and never disappointed when work was completed.

I've had an excellent experience working with them for both electrical and HVAC work as I remodel my 1785 home. I highly recommend them.

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!
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.
