Radiant Floor Heating for Winthrop Homeowners

When Winthrop homeowners need radiant floor heating, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Winthrop in Kennebec County — so we respond quickly and know the homes, the weather, and the codes in your area.
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.

Winthrop Homes and What They Need
Winthrop's median home dates to 1977, per Census estimates, with about 24 percent of housing built before 1940 and 35 percent before 1960 -- newer than neighboring Augusta or Gardiner, which fits a town that grew as a lakes destination rather than around an old mill or river port. That newer stock still means plenty of 1970s- and '80s-era systems reaching the end of their service life. Water heater repair calls on those original units are common.
Heating and Cooling in Winthrop
About 59 percent of Winthrop households heat mainly with fuel oil, 16 percent with wood, and 12 percent with electricity, and there is no natural gas utility in town. Winthrop's population roughly doubles every summer as seasonal camp owners return to its lakeshores, which drives a predictable spring rush of startup and shutdown plumbing work. For a camp that is slowly becoming a year-round home, a cold-climate heat pump paired with the existing oil or wood setup is a common upgrade path.

Getting to Know Winthrop
Winthrop started out in 1765 as a scattering of lakeside homesteads known informally as "Pondtown," then took its current name at incorporation in 1771, honoring Massachusetts's first colonial governor. For roughly 150 years, the Winthrop Mills Company was one of the country's largest woolen-blanket makers and the town's biggest employer -- a scale of industry that is easy to forget looking at Winthrop's lake-town feel today.
One of the more unusual local landmarks is the 'Ladies Delight Light' on Cobbossee Lake, a small lighthouse built in 1908 that is thought to be the only active inland lighthouse anywhere in Maine. The town has also been growing steadily for over a century, from about 2,088 residents in 1900 to 6,121 at the 2020 count, making it the largest town, as opposed to city, in Kennebec County.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Winthrop gets treated. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. That is how we keep customers calling back, one honest job at a time.
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

Radiant Floor Heat: Installation, Manifolds & Troubleshooting
Radiant floor heat is one of the most comfortable systems we install, and one of the least understood — most homeowners have never seen the manifold that makes the whole thing work.

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.

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.

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.
