What is Floor Heating Called? (5 Types You Should Know!)

What Is Floor Heating?

I want to start by talking about something that’s become a big part of my work and home life: floor heating. You know how sometimes you get out of bed in the morning, and your feet hit the freezing cold floor? Well, floor heating puts an end to that. It’s a system installed beneath your flooring that gently warms every step you take.

Floor heating is often called radiant floor heating because it warms the floor surface and then radiates heat upward throughout the space. Unlike traditional heating systems that blow hot air around, floor heating makes the entire room feel cozy and evenly warm without any hot or cold spots.

One thing I really appreciate about floor heating is how eco-friendly it can be. Since it heats from the ground up and works efficiently at lower temperatures, it saves energy. For anyone trying to reduce their carbon footprint or cut energy bills, this is a smart choice.

But there’s more than one kind of floor heating. Let me walk you through the five types I’ve worked with most, sharing stories, data, and tips that will help you figure out which might work best for you.

1. Electric Radiant Floor Heating

Electric floor heating is probably the first type most people think of when they hear “floor heating.” It uses electric cables or mats installed just under your flooring surface. When the system is turned on, electricity flows through these cables or mats creating heat that warms the floor.

Personal Experience

I installed an electric radiant floor heating system in my own bathroom a few years back. It was a game-changer during the winter months. I remember stepping out of the shower onto a warm floor for the first time — it felt luxurious yet simple. No more cold feet in the morning!

On a recent project, I helped a client install electric mats under their kitchen tile floor. They had been hesitant due to cost concerns but were thrilled with how quickly the system heated the space and how even the warmth felt.

Installation Insights

Electric systems are great for retrofits or small areas because the mats are thin and easy to install under tile or laminate. You don’t have to raise your floor height much, which helps keep renovations manageable.

The installation involves laying out mats or cables in a pattern, connecting them to a thermostat, and then securing your flooring over top. If you’re doing a DIY project, electric mats can be more straightforward than water-based systems.

Cost and Efficiency

Electric radiant floor heating has a moderate upfront cost — usually between $8 and $15 per square foot installed — but running costs depend heavily on your local electricity rates.

According to data from the U.S. Energy Information Administration (EIA), average electricity prices vary from about 10 cents per kWh in some states to over 30 cents in others. So if you live in an area with high electricity costs, electric radiant heat can get pricey to run.

However, because it heats quickly and directly, you often don’t need to keep it on all day. Using programmable thermostats can save you money by heating floors only when you’re home or using certain rooms.

Flooring Compatibility

Electric systems work well with tile, stone, laminate, and engineered hardwood floors. However, I usually don’t recommend them under thick carpet because carpet insulates heat away from the surface.

Pro Tip:

When installing electric floor heat under tile or stone, use a tile backer board to protect cables and ensure an even surface before laying your flooring.

2. Hydronic (Water-Based) Floor Heating

Hydronic floor heating circulates warm water through small tubes embedded beneath your flooring. This system is often used for whole-house heating because it’s highly efficient at warming larger spaces.

My Story With Hydronic Heating

A couple of years ago, I helped renovate a historic home where the owners wanted to keep old aesthetic charm but upgrade to modern comfort. We installed a hydronic system beneath new oak floors.

What amazed me was how gently and evenly the heat spread throughout their living areas. They told me their energy bills were noticeably lower than before despite heating a big house.

In another project, we combined hydronic floor heating with solar water heaters. The homeowner saw remarkable savings—nearly 40% less on winter heating costs compared to their previous gas furnace system.

How It Works

A boiler heats water that’s pumped through flexible plastic tubes laid out in loops under the floor slab or between joists on upper floors. The heated water warms the floor above, which then radiates heat into the room.

Because water holds heat so well, hydronic systems maintain warmth longer than electric systems after turning off. This means less frequent cycling on and off and better energy efficiency.

Installation Considerations

Hydronic systems require careful planning and professional installation. You’ll need space for a boiler or water heater, pumps, tubing manifolds, and control valves.

They’re ideal for new construction or major renovations since the tubing must be embedded into concrete slabs or installed beneath subfloors.

Energy Sources and Eco-Friendliness

Hydronic systems can be powered by natural gas boilers, electric boilers, or renewable sources like solar thermal panels or heat pumps.

I’ve noticed that pairing hydronic systems with solar thermal water heaters or geothermal heat pumps takes their efficiency and eco-friendliness to another level.

Cost Perspective

Hydronic systems tend to have higher upfront costs — around $12 to $20 per square foot installed — but they usually save money over time through lower operating costs especially if combined with renewable energy sources.

3. Air-Heated Floor Systems: What You Need to Know

Air-heated floors use warm air circulated through ducts beneath flooring surfaces. While they exist, I rarely recommend them for homes because of their inefficiency compared to water or electric systems.

Why I Steer Clients Away From This Type

When I first came across air-heated floors early in my career, I installed one in a commercial building as an experiment. The system was noisy and struggled to maintain consistent warmth.

Air doesn’t retain heat well—it loses temperature quickly as it moves through ducts—so these systems often require more energy input to keep rooms comfortable.

In residential projects I’ve consulted on since then, I’ve found better results using hydronic or electric solutions unless there’s a specific industrial or commercial need for air heating.

4. Radiant Floor Panels

Radiant floor panels are prefabricated panels containing embedded heating elements that you install under your flooring. They offer a modular approach to radiant heating.

Why Radiant Panels Work for Some Spaces

I recently used radiant panels in a commercial office renovation where speed was critical. The panels were easy to install over existing subfloors without raising them too much.

They distribute heat evenly across their surface area and can be integrated with various floor coverings like vinyl, laminate, and engineered wood.

Installation Tips

Radiant panels can be snapped together or laid side-by-side like tiles under your floor covering. Make sure your subfloor is level and stable for best results.

Panels come in different thicknesses; thinner options are best when you don’t want to raise your finished floor height too much.

5. Infrared Floor Heating: An Alternative Approach

Infrared heating uses far-infrared radiation to warm objects and people directly rather than just heating air or floors.

Where Infrared Shines (Literally)

In wellness centers and spas I’ve visited or worked with, infrared floor heating creates gentle warmth that feels very natural and comfortable without drying out the air.

It’s also popular in spaces where direct warmth on feet is desired without raising overall room temperature dramatically.

Benefits I’ve Seen

Infrared systems offer quick warm-up times and targeted comfort zones — great for small rooms or areas where you want heat only underfoot without heating everything else.

How To Choose The Right Floor Heating System For You

I get asked this question all the time: “Which system should I pick?” The honest answer is—it depends on several factors like your budget, home size, flooring type, climate, and lifestyle.

Here are some questions I ask myself or my clients when selecting a system:

• What kind of flooring do I have? For example:
  • Tile/stone floors pair well with both electric and hydronic systems.
  • Wood floors require careful moisture control; hydronic systems are often better.
• How big is the area?
  • Small rooms can be heated efficiently with electric mats.
  • Whole-house setups usually benefit from hydronic.
• What’s my energy source availability?
  • Gas boilers support hydronic well.
  • Electricity availability favors electric mats.
• What’s my budget for upfront costs versus long-term savings?
• Am I renovating or building new?
  • New builds allow easier installation of hydronics.
  • Renovations may favor electric mats due to minimal disruption.

Real Case Study: A Whole-House Hydronic Heating Setup

I want to share a detailed case study about a recent project that highlights how hydronic floor heating can save money and improve comfort.

A family hired me to upgrade their old forced-air furnace system in a 3,000 sq ft home in Vermont—a cold climate state where efficient heating matters most.

We designed a hydronic radiant floor system combined with a high-efficiency gas boiler. Tubing was embedded in concrete slabs downstairs and installed over wooden subfloors upstairs.

Results after one winter:

• Energy bills dropped by nearly 35%.
• Homeowners reported no cold spots or drafts anywhere.
• The even warmth made living spaces feel more comfortable.
• The quiet operation was appreciated compared to noisy forced-air vents.

This project convinced me that for colder climates and larger homes, investing in hydronic radiant floors pays off both financially and comfort-wise over time.

Maintenance Tips From My Experience

Floor heating systems don’t require much ongoing work but keeping them running efficiently is important:

• Electric Systems: Check thermostats periodically and inspect cables if you notice cold spots.
• Hydronic Systems: Annual boiler servicing is essential. Also inspect tubing manifolds for leaks.
• General: Clean sensors regularly and avoid heavy furniture blocking heat distribution.

I once had a client call me about uneven warmth in their hydronic system—it turned out some tubing loops had trapped air pockets. Bleeding those loops fixed the issue quickly.

Troubleshooting Common Issues

If your floor heating isn’t working as expected:

• Cold spots: Could indicate damaged cables (electric) or air trapped in tubing (hydronic).
• High energy bills: Check thermostat settings; programmable thermostats help.
• No heat: Verify power supply for electric systems; check boiler/pump operation for hydronic.

If in doubt, call a professional rather than trying DIY fixes that could cause damage.

How FloorTally Helps Me Stay On Budget

Estimating costs has always been one of my biggest challenges when advising clients about floor heating options. That’s where FloorTally comes into play for me.

With FloorTally, I input project details like room size, flooring type, labor rates in my area, and preferred heating system type. It calculates:

• Material costs
• Labor expenses
• Waste factors
• Total project cost estimates

This helps me give clients transparent numbers upfront so they can make decisions without surprises later on. It’s especially handy when comparing electric versus hydronic system costs side by side because it accounts for local price variations too.

I find this tool saves hours of manual calculations while improving accuracy — something every contractor needs when bidding jobs or planning budgets.

Energy Efficiency: Why Floor Heating Can Save You Money

One thing people often overlook is how floor heating improves overall energy use:

• Radiant heat warms objects directly rather than just air.
• Lower thermostat settings still feel comfortable because of warm floors.
• Zoned controls allow you to heat only occupied rooms.
• Systems paired with renewable energy sources cut fossil fuel use significantly.

For example, my clients who switched from baseboard heaters to radiant floors reported average savings of 20% on winter energy bills within the first year.

Final Thoughts: Is Floor Heating Right For Your Home?

After working on dozens of projects involving various types of floor heating, here’s what I believe:

Floor heating adds real comfort that lasts long after installation day. It’s especially worth considering if you:

• Want even warmth without drafts or noisy vents
• Have tile or stone floors that tend to feel cold
• Are planning new construction or major renovations
• Care about energy efficiency and reducing utility bills
• Enjoy walking barefoot indoors without freezing toes!
