Tankless Water Heaters for Kittery Homeowners
Endless Hot Water
Space-Saving Design
20+ Year Lifespan
When Kittery 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 Kittery in York 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.

Kittery Homes and What They Need
Kittery has the oldest housing stock of the York County coastal towns Aces serves, with a median build year of 1965 and about 25 percent of homes predating 1940 (46 percent predating 1960) -- fitting for a town that has been incorporated since 1647. On homes this old, a rewiring project often turns up several generations of electrical work layered on top of each other.
Water Supply and Drains in Kittery
The Kittery Water District supplies public water from a set of local surface reservoirs and ponds -- Bell Marsh Reservoir, Folly Pond, Middle Pond and Boulter Pond -- while the town runs its own wastewater treatment plant on Dennett Road. On Kittery's oldest streets, that long municipal history is worth knowing before assuming a drain cleaning call is a simple fix.
Getting to Know Kittery
Kittery was incorporated in 1647, making it the oldest incorporated town in Maine, and sits as the state's southernmost town, across the Piscataqua River from Portsmouth, New Hampshire. The Portsmouth Naval Shipyard, established in 1800 on Kittery's Seavey's Island, was the U.S. Navy's very first federal navy yard.
During the Revolutionary War, some of the first vessels ever built for the U.S. Navy, including the USS Ranger under John Paul Jones, were constructed right on Kittery's Badger's Island -- a history that still shapes the town's identity along the water.
Local & Independent — Not a Franchise
Aces Highlands answers to Kittery homeowners directly, not a franchise office somewhere else in the country. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. Getting invited back is the only metric that matters here.
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

How Aces Highlands Handles Tankless Water Heaters in Kittery
- Kittery Water District covers most of Kittery (surface-water reservoirs and ponds: Bell Marsh Reservoir, Folly Pond, Middle Pond, and Boulter Pond.) — homes still on a private well get the well and pressure tank looked at as part of the same visit.
- Unitil (Northern Utilities) reaches parts of Kittery, so a gas water heater is an option on those streets; propane, electric and heat-pump models work anywhere in town.
- We permit the replacement at the Kittery Code Enforcement Department, route the T&P relief valve to a code-compliant discharge, and handle gas hookups under our Fuel Board license.

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.
