Radiant Floor Heating for Kennebunkport Homeowners

Kennebunkport sits in York County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for radiant floor heating gets a technician who already knows the local housing and codes, not a first-timer.
Radiant floor heating delivers warm, even comfort from the ground up — no drafts, no noise, and no dust blowing through ducts. Aces Highlands installs hydronic radiant floor systems for new construction and renovations.
Hydronic radiant floor heating works by circulating warm water through PEX tubing installed beneath your floors. The heat radiates evenly across the floor surface, warming the room from the bottom up for consistent, draft-free comfort.
We install radiant systems in concrete slabs, under wood subfloors, and in staple-up configurations. Each system is designed with proper tube spacing, zone controls, and manifold sizing to ensure even heat distribution throughout your home. A new high-efficiency boiler is the ideal companion for a radiant floor system.
Radiant floor heating pairs perfectly with high-efficiency boilers and can also work with heat pump water heaters for an all-electric solution. We design each system based on your home, your floors, and your heating goals. Reach out for a consultation on radiant floor heating for your home.

Kennebunkport Homes and What They Need
Kennebunkport's median home was built in 1982, with about 13 percent of units predating 1940 and 29 percent predating 1960 -- a mix of early-1900s shingle-style cottages in the Cape Arundel Summer Colony Historic District alongside newer coastal construction. Those older cottages are prime candidates for a heat pump retrofit that extends comfortable use into the shoulder seasons.
Heating and Cooling in Kennebunkport
About half of Kennebunkport households heat mainly with fuel oil, with bottled or tank propane at 27 percent and electricity at 20 percent; there is no piped natural gas in town. With propane this common, a tankless water heater on propane is a popular upgrade for a seasonal cottage being used more of the year.

Getting to Know Kennebunkport
Kennebunkport was first incorporated in 1653 as Cape Porpus, renamed Arundel in 1701, and finally took its current name in 1821 to reflect a growing shipbuilding and trading economy. Walker's Point, the Bush family's summer estate here, has hosted world leaders including Margaret Thatcher and Mikhail Gorbachev.
Cape Porpoise remains a working fishing harbor village within the town, keeping its own restaurants, church, library and commercial fleet. The Cape Arundel Summer Colony Historic District, running from Chick's Creek to Walker's Point, is full of early-1900s shingle-style summer cottages that still define much of the town's coastline.
Local & Independent — Not a Franchise
We are an independent, Portland-based company, not a franchise chain routing your Kennebunkport job to a call center. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. Getting invited back is the only metric that matters here.
How Radiant Floor Heat Works
- Boiler — heats water for the loop
- Manifold — splits and balances flow to each loop
- PEX tubing — embedded in the floor slab
- Radiant floor — warms the slab evenly
- Heat rises — gently warms the room above

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.

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.

Radiant Floor Heating FAQs
Does radiant floor heating work under wood and tile floors?
Yes. Tile and stone are the best conductors and feel warmest; engineered wood and many hardwoods work well when water temperatures are designed for them; even carpet can work with the right pad. We design the tube layout and water temperature around your specific floor covering.
Can radiant floors heat my whole house?
Yes — with a properly done heat-loss calculation and design, hydronic radiant can be the sole heat source for a Maine home. In retrofits, many homeowners run radiant in key rooms and keep baseboard or a heat pump elsewhere, all off the same boiler with separate zones.
Is radiant floor heating efficient?
Very. Radiant runs low water temperatures that let condensing boilers operate at peak efficiency, distributes heat without duct losses, and keeps warmth at occupant level — so most homes feel comfortable at a lower thermostat setting than with forced air.
Can you add radiant heat to an existing room?
Often yes. If the subfloor is accessible from below (an unfinished basement under a kitchen, for example), staple-up radiant installs without disturbing the finished floor. Bathrooms and kitchens being remodeled are the other classic opportunity.
How long does a radiant floor system last?
The PEX tubing itself is typically rated for 50+ years — it generally outlives the boiler feeding it. The system has no moving parts in the floor; circulators and controls at the boiler are the only components that ever need service.
