When Gray 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 Gray 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.

  • Diagnostics come first, upsells do not — the invoice matches the quote
  • Scheduling that moves quickly, because a home without heat or water cannot wait
  • Properly licensed and covered by insurance, and reviewed by real customers on Google

Gray Homes and What They Need

Gray's roughly 4,600 homes are younger than much of Cumberland County. Census estimates put the median year built at 1983, and only about one in eight predates 1940. Those older houses cluster around Gray Village and along the old roads out toward Dry Mills. The bigger story is the building wave of the 1970s through the 2000s, when capes, ranches and colonials went up on wooded lots within reach of Turnpike exit 63; about a quarter of homes date from 2000 or later. Roughly one in twenty is a manufactured home, and around 670 units are held for seasonal use, many of them camps on Little Sebago, Crystal and Forest lakes. Houses from the 1980s and 1990s are now reaching the age where original boilers, furnaces and electrical panels with no spare breaker space come due, while a lakeside camp raises questions about insulation and year-round use.

Water Supply and Drains in Gray

Water in Gray is a patchwork. The Gray Water District runs mains through the village and along roads such as Shaker Road and Lewiston Road, but the town has no public or district sewer, even where a water line passes the door, so every home relies on a septic system. Outside the district, households drink from private wells, and bedrock wells here deserve testing: in a USGS review of 2005-09 lab results, about 27 percent of Gray wells sampled exceeded the federal arsenic standard, among the higher rates in Cumberland County. East Gray also carries the history of the McKin Superfund site, where solvents from a 1960s-70s waste facility reached private wells and nearby residents were offered public water. The practical upshot is treatment equipment matched to the well, pressure tanks kept in working order, and tank water heaters chosen with the water chemistry in mind.

Getting to Know Gray

Gray holds one of Maine's most unusual Civil War stories: in 1862, the body of an unknown Confederate soldier was mistakenly shipped to Gray instead of a fallen local Union lieutenant. The women of the town buried the stranger in Gray Village Cemetery and paid for his headstone — marked simply "The Stranger" — and the grave is still tended today. Gray is also home to the Maine Wildlife Park, the state's refuge for animals that cannot return to the wild.

From the village center out to Dry Mills, Gray's homes range from 1800s farmhouses to newer builds off Route 26 — and we service heating, plumbing, and electrical in all of them.

Local & Independent — Not a Franchise

Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Gray gets treated. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. Earning the next call, not hitting a sales target, is the entire business plan.

How a Tankless Water Heater Works

  1. Flow sensor — detects water flow and triggers ignition
  2. Burner — fires on demand, no standby tank
  3. Heat exchanger — heats the water as it passes through
  4. Hot water out — instantly, only when it's needed
  5. 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 Gray

In Gray, plumbing permits come from the Local Plumbing Inspector at the Gray Code Enforcement Office (Henry Pennell Municipal Complex, 24 Main Street, Gray, ME 04039, (207) 657-3339). With 8,269 residents, Gray is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Gray includes frontage on Little Sebago Lake, Crystal Lake and Forest Lake and is drained by Collyer Brook — all relevant to well/septic siting and shoreland zoning outside the water district's service area.

  • 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

How Aces Highlands Handles Tankless Water Heaters in Gray

  • Most Gray homes are on Gray Water District water from Libby Brook aquifer wells at 80 Shaker Road (primary) plus a secondary well on Yarmouth Road; about 1,100 connections, not the whole town; on a private well, we check the pressure tank and water quality alongside the tankless water heaters.
  • Where Unitil has a main nearby, gas is usually the lowest-cost tankless water heaters option in Gray; off the main, propane, electric and heat-pump units all work.
  • The swap is permitted through the Gray Code Enforcement Office, the relief valve gets a proper gravity discharge line, and any gas connection is made under our Maine Fuel Board license.

    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.

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.
