A floor heating system in Florence, AL warms your home from the ground up instead of blowing air through vents and registers. More Shoals-area homeowners are adding radiant heat during remodels and new builds because it kills drafts and keeps tile floors comfortable through January cold snaps. Here's what it costs, how electric compares to hydronic, and what Alabama requires before a contractor opens up your subfloor.
This guide was put together by the heating team at Hennhaa Heating & Air, licensed HVAC contractors who've handled radiant retrofits in older Florence brick homes and new-construction slabs out toward Sweetwater.

What Is a Floor Heating System?
A floor heating system, also called radiant floor heating, warms a room by heating the floor surface directly. That heat then radiates upward into furniture, walls, and the people standing on it.
There are two main types:
- Electric radiant heat uses thin cables or mats installed under tile, stone, or engineered wood.
- Hydronic radiant heat circulates heated water through PEX tubing connected to a boiler or water heater.
Both skip ductwork entirely. That's the main reason rooms with radiant floors feel warm even when the thermostat reads a few degrees lower than it would with a forced-air system.
How Much Does a Floor Heating System Cost in Florence, AL?
Pricing depends on square footage, flooring type, and whether you're heating one bathroom or an entire house. National cost data gives a realistic range to plan around before you get a local quote.
| Project Scope | Electric Radiant | Hydronic Radiant |
|---|---|---|
| Cost per sq ft (heating only) | $8 – $15 | $7 – $17 |
| Single room (bath, kitchen) | $1,500 – $6,400 | $1,500 – $6,400 |
| Whole-home system | $12,000 – $30,000 | $13,700 – $43,000 |
These figures reflect <a href="https://www.blockrenovation.com/guides/how-much-do-heated-floors-cost-in-2026">national 2026 installed pricing for radiant floor heating</a>, including labor, materials, and a dedicated thermostat. Whole-home hydronic jobs run higher because they often require a new boiler, roughly $3,200 to $9,000 on top of the tubing itself.
Adding new flooring on top of either system pushes the per-square-foot number up, since you're paying for tile or engineered wood in addition to the heating layer.
Electric vs. Hydronic: Which Fits Your Florence Home?
For a single bathroom remodel, electric usually wins. For a new-build floor plan or a whole-house retrofit, hydronic tends to cost less to run over time.
| Factor | Electric | Hydronic |
|---|---|---|
| Install complexity | Faster, simpler retrofit | Slower, needs boiler or water heater tie-in |
| Warm-up time | 30–60 minutes | 60+ minutes, but holds heat longer |
| Best use case | Bathrooms, kitchens, small additions | Whole-house heating, new construction |
| Running cost | Higher per sq ft over time | Lower per sq ft over time |
If your Florence home already has a boiler for a hot water system, extending it into a hydronic radiant zone is often more cost-effective than starting from scratch. Homes without a boiler usually come out ahead with electric mats for the rooms that need it most.
Why Radiant Floor Heating Works Well in the Shoals Climate
Florence winters are short and mild compared to the rest of the country, but the humidity doesn't take a break. Forced-air systems stir up moisture, dust, and pollen as they run, which can make a heated room feel muggy instead of simply warm.
Radiant floors sidestep that problem because they heat surfaces directly instead of pushing air around. Rooms feel comfortable at a lower thermostat setting, and there's no blower noise or draft near doorways and windows.
Because Florence's heating season is short, zoning also matters more here than it would up north. You can run radiant heat only in the rooms you're using on a 40-degree morning instead of conditioning the whole house for a cold snap that might not last the week.
Benefits Beyond the Cost Savings
Radiant heat doesn't just feel different, it performs differently.
- No duct losses. The <a href="https://www.energy.gov/energysaver/home-heating-systems/radiant-heating">U.S. Department of Energy notes that radiant heating is typically more efficient than forced-air heating</a> because no energy is lost through ductwork.
- Fewer allergens circulating. Without a blower pushing air through vents, radiant systems don't stir up the dust and pollen that collect in ducts, which matters in a climate as humid and pollen-heavy as North Alabama.
- Fewer moving parts. No blower motor, no cracked heat exchanger, no leaky plenum. What's left to maintain is mostly the thermostat and, for hydronic systems, the boiler or circulator pump.
- Even heat, no cold spots. The whole floor plate radiates warmth instead of one or two registers doing all the work.
Licensing and Installation Requirements in Alabama
Installing a floor heating system touches electrical work, subfloor modifications, and sometimes plumbing, all of which require permits and code-compliant work.
Alabama regulates this through more than one board, depending on the system:
- Contractors who install, service, or repair heating apparatus, including radiant floor systems tied to a central heat source, must hold a license from the <a href="https://hacr.alabama.gov/">Alabama Board of Heating, Air Conditioning & Refrigeration Contractors</a>.
- Electric radiant mats and cables that tie into your home's wiring fall under separate electrical licensing rules.
Ask any contractor you're considering for their license number before signing a contract, and verify it directly with the board. A properly licensed installer also knows how to size the system correctly and tie it into your existing panel or water heater without voiding manufacturer warranties.

If a floor heating system turns out to be more than your home's layout or budget can support right now, a heating system upgrade or new furnace installation is worth comparing before you commit.

FAQ
How much does a floor heating system cost in Florence, AL?
Expect $7 to $17 per square foot installed for the heating layer alone, or $1,500 to $6,400 for a single bathroom or bedroom. Whole-home systems typically run $12,000 to $43,000 depending on electric vs. hydronic and whether a new boiler is needed.
Can radiant heating be installed under any type of flooring?
Yes, with the right underlayment. Tile and stone conduct heat most efficiently, engineered wood works with the correct spacer system, and thick carpet padding slows heat transfer slightly but doesn't rule it out.
Can you add floor heating to an existing house, or only new construction?
Both. Electric mats are commonly retrofitted into a single room during a flooring replacement, since they add minimal height. Hydronic retrofits are more involved but doable, especially if a boiler is already in the house.
How long does a floor heating system last?
Hydronic PEX tubing is built to remain under the floor for decades, often outlasting the home's other mechanical systems, while electric mats and cables are typically rated for 25 to 35 years. The parts most likely to need service are the thermostat, pump, or boiler, not the tubing or cable itself.
Does radiant floor heating require much maintenance?
No. There are no filters to change and no ducts to clean. Electric systems need almost no upkeep beyond the thermostat; hydronic systems benefit from an occasional boiler and pump check.
Is radiant floor heating worth it for Florence's mild winters?
Yes, especially for tile and concrete floors that feel cold even when the air temperature is fine. Zoning lets you heat only the rooms in use, which suits a short heating season better than running a furnace for the whole house.
Does floor heating need a dedicated electrical circuit?
Electric radiant systems typically need their own thermostat-controlled circuit sized to the mat or cable load. A licensed contractor will confirm your panel has room before installation, which is one more reason to get a load calculation as part of the quote.
