9 Pros and Cons of Heated Floors


Spot Heating Lifestyle 2

What is electric radiant floor heating? Radiant heated floors have been around since the Roman Empire in one form or another. In the United States, electric floor heating has become a popular trend for both new and retrofit projects. Nevertheless, there’s still a learning curve among many homeowners. How do heated floors work? What are the pros and cons of radiant floor heating? How do you know if in-floor heating is right for you? Those are the questions we’ve set out to answer to reduce the learning curve.

How does Radiant Floor Heating Work?  

Traditional heating systems heat the air, which then warms up the people in the room. Radiant heating systems work by directly warming the people and objects in a room. How warm do heated floors get? The floor temperature can be set as high as 104° F but users will typically set it to a more comfortable range of between 80° F and 85° F and control it from a thermostat from there. This type of heating often feels like the warmth of the sun, because radiant heat warms via heat radiation. This allows people to feel warm even when the ambient (air) temperature in the room is actually cooler. It’s the same concept as standing in direct sunlight vs. standing in the shade.

Can Radiant Floor Heating Benefit your Home?  

Have you ever walked into a room in your house that was noticeably colder? Or have you ever stepped out of the shower or tub and felt a chill? Most homes have these “cold spots” due to tile flooring, which is inherently cold, or other factors like a cement slab, unheated crawl space and unheated garage. If you're wondering, "Can radiant floor heating heat an entire house?" The answer is that while nearly all homes can benefit from radiant floor heating, floor heating won't always be enough to serve as the only heat source.

Some of the most common rooms to heat are bathrooms, kitchens, basements and bedrooms located over a garage or unheated space. To decide which radiant floor heating system is right for your project, you should first be familiar with the different types of radiant heating systems.

Electric Floor Heating vs. Hydronic

What is the best floor heating system? The two main types of radiant heat are electric and hydronic. Both function the same way — they create warmth under the flooring and radiate it upward into the room above — but the way they do it is different.

Electric floor heating systems use electric heating elements woven in a serpentine pattern to heat the floor. They’re known for being easy to install (you could even do it yourself if you’re pretty handy) and ideal for remodeling projects. They also heat up in 30-60 minutes, so homeowners can turn them on and off as needed to keep costs down.


Hydronic floor heating systems use hot water pumped through plastic tubing laid out in a serpentine pattern to heat the floor. They’re ideal for whole-house heating, but professionals suggest installing them during the home’s construction because they can be difficult to retrofit if the home isn’t already outfitted with the proper equipment. The upfront cost of a hydronic floor-heating system is typically higher because it requires a boiler, a pump and gas lines. However, the cost of operation is generally lower when the square footage is greater (i.e. when heating multiple rooms or an entire house). Hydronic systems also take a greater amount of time to heat up, requiring most homeowners to leave them on around the clock, resulting in more energy usage.

Overall, if you’re remodeling a bathroom or want to add supplemental heat to small areas of your home, an electric floor heating system is right for you. But, if you’re building a new home and wish to have heated floors throughout, you should consider either electric slab heating cables which can be installed directly in a concrete slab or a hydronic floor heating system.

Pros and Cons of Radiant Heating

Whether you choose electric or hydronic radiant heat, there are pros and cons. This list will break them down while noting any exceptions between the two types.  

Pros

1. Uniform heating

The biggest benefit of floor-heating systems is their ability to uniformly heat a room and floor. Forced-air heating systems use vents to distribute warm air throughout a room. The location of the vents determines which parts of the room will be warmer than others. In contrast, radiant floor heating systems heat the entire floor, which leads to an evenly heated room and for an even ambient temperature around a person's body. This means that you will feel more comfortable at a lower ambient temperature level because you won't experience cold drafts. 


2. No maintenance

Electric floor-heating systems do not require maintenance. In fact, WarmlyYours’s TempZone™ electric floor-heating system is warrantied for 25 years. If damage does occur to the cable during installation, a professional can use a thermal imaging camera to locate the issue and make the repair. Hydronic floor-heating systems do not offer this benefit. WarmlyYours offer Floor Heating support.

3. No noise

Radiant floor heating systems are known for being quiet. Unlike forced-air systems, there isn’t a loud furnace that kicks on. Therefore, you won’t hear anything while they’re on.

4. Non-allergenic

Because floor-heating systems directly warm the people and objects in a room via radiant heat, they do not disturb any existing dust and allergens. This is a major downfall for forced-air systems, which blow around dust and other particles while they distribute heat.

5. Energy efficient

Electric floor-heating systems are at least 25 percent more efficient than forced-air systems. That’s because they do not provide an escape route for the heat they produce. Therefore, virtually all of the heat that’s produced is retained. In contrast, forced-air systems use ductwork that is susceptible to leakage. 

Is whole house radiant floor heating effective? Yes, under the right circumstances, a properly designed system can act as a primary heating source in the room or whole house.

Electric floor-heating systems also are energy efficient because they only take 30-60 minutes to heat up, thus allowing homeowners to use a programmable thermostat, WiFi thermostat, or to manually turn them on and off (or up and down) as needed in rooms that are in use. This allows you the ability to "customize your comfort" on a room-to-room basis. Hydronic floor-heating systems aren't typically able to do that and they take much longer to heat up, requiring homeowners to leave the system on continuously, thus using more energy. However, they are still efficient in terms of retaining heat.

Generally speaking, the radiant floor heating cost to operate is very low. In fact, for a typical bathroom, it will cost you less than a dollar a day to run the system. 

6. Easy to install



Electric floor-heating systems are so easy to install that a handy DIYer can even do it. Which electric in floor radiant system do you recommend? It depends on a large number of variables including project budget and installation capabilities but the good news is that floor heating systems can be used under almost any flooring type. They’re available in rolls that already have the heating cable attached to mesh in a serpentine pattern. Therefore, all the installer has to do is roll them out and cut and turn them where necessary to fill up the room. They’re also available in loose cable with an installation membrane that features square-shaped “studs” to hold the cable in place. This option also offers crack prevention benefits for a heated tile floor. In contrast, hydronic systems are not as easy to install. They require a professional for installation.  

Another advantage of radiant floor heating installations is that they require no additional duct work, which can be both costly and time consuming. 

Cons

7. Flooring must be replaced

Whether electric or hydronic, floor-heating systems require any existing flooring to be removed before the radiant floor heating can be installed. That’s why these projects are ideal to complete during a remodel or new-home construction. This would be one of the main disadvantages of radiant floor heating.

8. Slightly elevates the floor height

Depending on the system you choose, the height of the floor will be elevated. WarmlyYours offers floor-heating systems that are only 1/8 inch thick, resulting in very minimal floor elevation. However, whether you choose to use an installation membrane or underlayment will also factor in to the floor height. Overall, the height of the floor is typically only raised about ½ inch in most electric floor-heating projects. On the other hand, hydronic floor-heating systems require the floor height to be raised significantly more.

9. Cost

Depending on the project, radiant floor heating can be costly. Electric floor-heating systems typically cost between $10 and $20 per square foot, depending on the system you buy. However, if the cost of electricity is high in your area, the cost of operation will be higher. Usually this is not an issue because the systems can be controlled with a thermostat to save energy, but it’s something that’s important to look into before you start your project. Does radiant floor heating raise or lower your energy costs? The answer is pretty simple. You will see an increase in your electricity bill but it will most likely be offset by significant savings from reductions in your heating bill.  

Contrary to electric systems, hydronic floor-heating systems are typically more expensive upfront because they require a boiler, a pump and gas lines to operate. However, if they are being used throughout a house, their cost per square foot goes down because multiple rooms share the cost.
