9 Pros and Cons of Heated Floors


Spot Heating Lifestyle 2

Do you love the feeling of walking on a warm floor in winter? If so, you're not alone. A lot of people enjoy the comfort and convenience of heated floors. You are probably wondering, what are they all about, how do they work, what about the cost and maintenance? We have all the answers for you! This guide will take you through everything you need to know about heated floors and explain their pros and cons in-depth. Let's get started!

What Are Heated Floors?

Heated floors, or radiant floor heating, is a system where either electric wires or hot water pipes are installed underneath the flooring to create warmth. The heat then radiates up and warms the room evenly from the ground up. Radiant floor heating is an efficient way to heat a room since there are no bulky radiators or vents that can take up valuable space.

How does Radiant Floor Heating Work?  

Did you know that radiant heating systems date all the way back to the Roman Empire in the form of hypocausts? Traditional heating systems such as fireplaces and space heaters are inefficient when compared to radiant heating systems since they heat the air directly. This causes hot air to rise while the cold air sinks, resulting in an uneven distribution of heat in a room. Radiant floor heating overcomes this by warming the objects and people in a room directly.

The heated floors work by either circulating warm water through pipes or by passing an electric current through wires which generates electrical resistance. The heat then radiates up and warms the rest of the room evenly via radiation.

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. To see if floor heating can be a primary heat source for your home, make sure to check out our Heat Loss Calculator

Some of the most common rooms for radiant heat are bathrooms, kitchens, basement 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.

How Warm Do Heated Get?

Most floor heating thermostats allow you to either control your radiant heating system with the ambient temperature (so the temperature in the room itself) or, if your system was properly installed with a floor sensor, with the floor temperature (the temperature that the floor sensor picks up). The floor temperature will almost always be warmer than the ambient temperature since some heat is lost to transference when the floor materials are warmed up.

While floor temperature can be set as high as 104° F, the floor temperature is usually set between 80° F and 85° F, which is comfortable for most people (depending on the room and ambient temperature).

The feeling of radiant heat is very similar to what you experience on a summer day when the sun suddenly appears from behind a cloud. Except in this case, you don’t have to worry about clouds when it comes to floor heating!

Types of Radiant Floor Heating

There are two types of radiant floor heating: electric and hydronic.

Electric radiant floor heating uses electrical resistance to generate heat through mats or wires installed underneath the floor. The electric elements are woven in a serpentine pattern to ensure that the heat is evenly distributed. Many electric floor heating elements are designed to be embedded in thinset or self-leveling cement under the floor covering but some heating options, like our Environ product line, are meant to be installed without adhesives which can cut down on project costs. 

Hydronic floor heating, otherwise known as hot water heating, uses water that is heated by a boiler and then circulated through plastic pipes. The heat from the water warms the floor and radiates throughout the room.

Electric vs. Hydronic Radiant Floor Heating

Both electric and hydronic floor heating systems do the work of heating your floor to make your home more comfortable. There are, however, some differences in how they operate. Here's a quick rundown.

Electric radiant floor heating is easy to install and can be done as a DIY project. They are also more affordable up-front and are ideal for smaller areas or rooms. Additionally, they are versatile and can be used with all types of flooring. Finally, a properly installed electric floor heating system requires essentially no maintenance to run properly.

Hydronic radiant floor heating, on the other hand, can be used to heat larger areas than electric. It, however, takes a longer time to heat up compared to electric radiant floor heating, which typically takes around 30-50 minutes to heat up. This means you might have to leave them on for a couple of hours before you need the heat. Additionally, they are more expensive to install but can last for decades with proper maintenance. The installation is more complex and usually requires a professional. It also requires higher up-front costs because of the boiler and associated equipment.

Generally, both methods are effective in providing radiant floor heating. The main difference lies in the installation process, the cost, and the time it takes to heat up the floor.

If you are doing a complete home remodel or building a new home, a hydronic in-floor heating system would be ideal. On the other hand, the electric radiant floor heating system would be a better and more affordable option if you are renovating a room (or a few rooms) or looking to only add floor heating to specific areas in your home.

Pros and Cons of Radiant Heat

The epitome of luxury and comfort has to be radiant heated floors. The idea of having warm floors to walk on during those cold winters or even enjoying the warm bathroom floors while you get ready for your day is very appealing. Radiant floor heating comes with a lot of benefits, as well as some drawbacks that are important to consider before making the investment. Let us explore in more detail below.  

Pros of Radiant Heated Floors

Sure, maybe we're biased but there really is a lot to like about installing heated floors

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, underfloor radiant heating heats 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

Radiant floor heating systems do not require any maintenance. Once they are installed, they will last for 20+ years without any issues. In fact, WarmlyYours warranties its TempZone™ electric floor-heating system for 25 years (and for life if the system is installed with our SmartInstall service . If there is any cable damage during the installation process, a thermal imaging camera can be used to easily and quickly find and repair the issue. In case you need any floor heating support, WarmlyYours has you covered!

Note: Hydronic floor-heating systems do not offer this benefit.

3. No noise

Imagine trying to concentrate on your work with the sound of a furnace running in the background. It would be very difficult to focus, right? This is not an issue with radiant floor heating as they are very 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

Radiant floor heating does not move air around, meaning there is no circulation of dust or other allergens in the room. This is a major benefit for people who suffer from allergies or asthma.

5. Energy efficient

Radiant floor heating is one of the most energy-efficient ways to heat your home. In fact, they are considered at least 20 to 25% more energy-efficient than forced-air heating systems. This is because the heat is evenly distributed throughout the room, so there is no need to overheat the room to compensate for cold spots. Additionally, radiant floor heating is very efficient because it doesn't rely on ductwork that can leak heat.

Furthermore, thanks to the advanced technology, you can easily regulate the temperature of the room using a WIFI or Programmable thermostat. This means that you only heat the room when you need to and can lower the temperature when you are not using the room. As a result, you save energy and lower your energy bills.

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 of Radiant Heated Floors

Every coin has two sides, and radiant heated floors are no different. While there are many benefits, there are also some drawbacks that you should be aware of.

7. Flooring must be replaced

If you want to install radiant heated floors in your home, you will need to replace your existing flooring. This is because radiant heated floors need to be installed under the new flooring. The most popular choice for radiant heated floors is tile because it conducts heat very well. However, you can also choose from a variety of other options, including laminate, floating hardwood, nailed hardwood, vinyl (including LVT), etc.

8. Slightly elevates the floor height

Radiant heated floors need to be installed on top of a subfloor, so your existing flooring will be raised by about an inch. This can be an issue if you have doors that swing into the room, as they may not clear the new flooring. With our ultra-thin Environ heating mats and our TempZone floor heating elements (even with embedding thinset) the floor height increase will be much smaller (typically 19/64" for Environ plus CeraZorb insulation underlayment and 3/8" for TempZone heating elements embedded in thinset or SLC). 

9. Cost

The initial cost of radiant heated floors can be higher than other types of heating systems. Depending on the system you purchase, electric floor heating systems range in price from $10 to $20 per square foot. You can use our Floor Heating Quote Builder to see how much a system costs for your project. You can also check out our Operating Cost Calculator to find out how much it will cost to run the system.

However, you need to keep in mind that radiant heated floors last much longer than other heating systems and are very energy-efficient. In the long run, you will actually save money by installing radiant heated floors.

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.

Interested to know if retrofitted hydronuc radiant heat will buckle an oak hardwood floor due to expansion. Floor has mostly been in place for several decades with some sections newish (couple of years).

WarmlyYours Responds...

Thanks for the question! We'd need more information to provide you with a concrete answer so please feel free to give our 24/7 technical support team a call at 1-800-875-5285. But with that being said, we can try to provide some help based on the information you've already provided. The good news is that, generally speaking, there are rarely any issues with pairing a properly installed hardwood flooring with a radiant heating system. Overly high moisture content in the wood would be the most likely culprit to cause a hardwood floor to buckle or warp but manufacturers will typically dry their wood to a moisture level so that this isn't an issue--so if possible, you'll want to check the reported moisture content of the wood from the manufacturer and also check the moisture content in your own home. Oak itself, of almost all varieties, is generally pretty compatible as a floor covering with radiant heating. It has relatively low R-Values (meaning it doesn't significantly impede the transfer of heat) and relatively low shrinkage rates compared to other common wood flooring types: https://www.launstein.com/radiant-heating.html. There are a lot of other variables that could impact how radiant heating will interact with your floor (such as installation method, the dimensions of the wood, the grain orientation) but the biggest potential issue with the scenario that you've outlined is that there may be significant differences between the initial floor and the new sections. It's unlikely, but there could be differences in the grain orientation or the installation method that could cause issues where the new and old boards abut (the moisture content between the new and old sections should be relatively similar as they've had years to reach equilibrium with your home). Hope that helps somewhat!

Hi. Can I use rugs on a floor with electric radiant heat?

WarmlyYours Responds...

That's a great question and your answer ultimately depends on what flooring type you're using with radiant heating. We recommend limiting the use of rugs with a radiant heating system if the flooring type is laminate or engineered wood, as the rugs can trap heat and potentially discolor the floor over time. Tile, the most commonly heated flooring type, doesn't typically have this issue but you'll want to make sure the rug you select doesn't have a high degree of insulation or it can prevent the heat from radiating upward into the room efficiently.

I have heated tile in the bathroom, what temperature do you recommend so that it’s warm. I have it on a timer always 73 then 77 when I’m going to be in it. It just seems Luke warm. Is that right? Never had before so not sure. Thanks

WarmlyYours Responds...

Thanks for reading. I'll try to give you some answers based on the information you've provided. It sounds like your floor heating thermostat might be indicating floor temperature and not the room temperature, so you'll need to turn that up to improve the comfort level. Our suggestion would be to try and set that temperature at 82°F and then adjust upwards from there until it reaches the comfort level you desire. I hope that helps but, as always, feel free to call our 24/7 technical support team (1-800-875-5285).

Hello, we’re buying a home w/ a radiant floor heating system. We live in snow country and we’re wondering how much heat we should expect from the floor and how much we should plan on using the wood stove?

WarmlyYours Responds...

That's a great question but unfortunately your answer will depend on a couple of variables, including what kind of radiant heating system is installed and how much heat loss your home is likely to experience. Your best option is give us a call at 1-800-875-5285 and one of our technical support team members can help provide you with an answer. But to get a really rough estimate of how much heat your system will produce, you can take the total heat output of the radiant heating system in watts and then multiply that by 3.41 to get the BTUs per hour. For example, our TempZone Flex Roll provides about 15 watts per sq. ft. So if that's installed in a 40 sq. ft. room, the total wattage for the system would be 600 watts. Then if you multiply that by 3.41, you'll end up with 2,046 BTUs per hour. Hope that helps!

Anyone ever use these in RV's?

WarmlyYours Responds...

Our systems have been used in RVs in the past. If you have the ability to connect your system to a 120V power source, you should have no issues but please don't hesitate to give our technical support team a call at 1-800-875-5285. Using a radiant heating system for an application like adding heat to an RV is beneficial because of the low energy costs.

Do electric floor heating systems work ok in a family/dining/kitchen area, probably around 900 square feet of area?

WarmlyYours Responds...

That's a great question. While that's a large project, there shouldn't be any reason that an electric floor heating system wouldn't be able to provide at least supplemental heat for that application as long as your breaker panel has the required space. With a project that size you'd also need to use a couple of power modules in addition to a master thermostat. But as long as those conditions are met, the heating system itself will provide a consistent heat output for the room. If you have any additional questions, please don't hesitate to give our technical support team a call at 1-800-875-5285.

I have a bathroom that I will be putting a tile floor in. I only want to heat about half of the floor but not the other half, however I want the floor to stay the same height across. Can this be achieved?

WarmlyYours Responds...

That's a very good question! Yes, the type of installation you've outlined can be achieved by using self-leveling cement/compound (SLC) to completely embed the heating system in (this layer is typically about 3/8" thick). That way, the SLC will create a smooth, even surface (over the half of the floor with the heating system and the half of the floor without it) on which to install your tile.

I building a relatively small home (1000sq ft) in southern Utah. I will have concrete polished floors - is there a way to have zones for warmth with an electric system or is it a central overall control?

WarmlyYours Responds...

You can certainly set up zoned heating with an electric floor heating system. Our typical suggestion for that application is to have a separate thermostat for each zone that controls the heating elements in that zone. Using programmable thermostats for this type of application will allow you to set a similar schedule for each thermostat or to set custom heating levels for each zone.

I am building a 1485sq foot slab house what would be my best option on floor heat

WarmlyYours Responds...

If you haven't poured the slabs yet, our recommendation would be our Slab Heating Cables or Mats. These heating elements are embedded in the slab itself. However, if you're planning to install a floor covering on top of the slab, you may want to consider one of our other floor heating elements (like TempZone or Environ) combined with an insulating underlayment to help prevent heat loss to the slab.

Can radiant heat systems be used with LVT (luxury vinyl tile) flooring?

WarmlyYours Responds...

Absolutely! We always recommend using a heating element from our TempZone product line for warming LVT floors because those heating elements are embedded in a layer of self-leveling compound beneath the floor. This creates a flat, uniform surface that keeps the relatively thin LVT floor covering from conforming to the shape of the heating cables when heated. You can learn more about floor heating for LVT here: https://www.warmlyyours.com/floor-heating/luxury-vinyl-tiles

Can I heat a 1500 square foot home with radiant heat

WarmlyYours Responds...

You absolutely could heat a 1,500 sq. ft. home with radiant heating but that efficacy of that system as a primary heat source would depend on a couple of factors including the typical weather in the area and the heat loss the home experiences. We can help walk you through the process of figuring out if electric floor heating would be right for your project, give us a call at 1-800-875-5285.

Unusual application. I have a 19'x10" wall chase along an exterior wall (frame house) where plumbing will be. The space is prepared with cement board flooring over foil faced rigid foam and insulated wall to an R19-21 rating. Can I use this product imbedded in swift-set to maintain a conditioned space to retard freezing.

WarmlyYours Responds...

We would not recommend installing a floor heating element (even if it's embedded) in your wall. In fact, it's against NEC to put electric floor heating in a wall. However, we do have a self-regulating heating product called "Pipe Freeze Protection" that should be able to help prevent your pipes in that wall. Don't hesitate to give us a call (1-800-875-5285) if you have any further questions!

If I had Hydronic floor heating, and installed vinyl flooring, would the flooring put off a smell when heated?

WarmlyYours Responds...

That's a very interesting question. The new vinyl flooring might have an inherent smell (as many vinyl products do) but it shouldn't be made worse by using floor heating (electric or hydronic). We've been heating vinyl floors for many, many years and we've yet to have a customer lodge that particular complaint so we're reasonably confident that the answer to your question would be no.

We are getting ready to convert a 500 sq ft garage/shop into a small one bedroom apt. Right now there is a concrete slab - would this work well to heat the whole space? or do you also need alternate heat source? We were planning on using ductless wall mounted heat/air units. Would this system work well under a bamboo floated floor and tile in bathroom?

WarmlyYours Responds...

You could absolutely install a floor heating system under bamboo and/or tile (the exact heating elements to use would depend on how the bamboo is installed). But as to whether or not the heating system could be the primary heat source, that would depend on the amount of heat loss the room would experience. We have a tool that you can use to get a rough estimate of whether or not a floor heating system can be the primary heat source. All you have to do is enter some project details and create a WarmlyYours account (if you don't have one already): https://www.warmlyyours.com/floor-heating/heatloss-calculator

I am installing porcelain tile flooring in my N.Y. home. I don’t plan on heating the entire kitchen floor., just the main cooking area. Are there any issues with tile cracking because of differences in temperature of the tiles.

WarmlyYours Responds...

That's a great question! You shouldn't have any issues with your tile cracking from differential temperatures. In fact, we often recommend this type of heating (we call it "spot heating" where you only heat the most used areas of the floor) because it helps cut down on both product and operational costs.

Building a 2000 sq ft house in interior Alaska. The cost of electric is high. Would like to know about radiant heat (water base) price wise and can it be installed under the subfloor (in crawl space) because putting down self leveling cement is going to cost alot also.

WarmlyYours Responds...

That's a very interesting question. I wouldn't completely rule out electricity since there may be options to help reduce operation costs for your project (so please feel free to give us a call at 1-800-875-5285 so we can discuss this in greater detail). However, since you're asking specifically about hydronic systems, we would direct you to try and contact a local rep for either Rehau, Uponor, or Viega since we don't specialize in this type of heating. Those reps should be able to provide some information about cost and installation for your project. Hope that helps!

Are there any reasons that one shouldn't put a freestanding soaking tub on a radiant heat tiled bathroom floor?

WarmlyYours Responds...

As long as the weight of the tub (with water and occupants) doesn't break up the floor, the floor heating system should be fine. Another consideration is if there will be any anchoring elements (like screws) to hold the tub in place on the floor because these could damage the heating cables.

I have gotten different answers from different contractors on this question I have an outside wall where the kitchen is, this will be our primary source of heat in the kitchen (steam in rest of home) almost every contractor told me it would be ok to run a 3 3 or 3 4 configuration just to keep a level of warmth in the cabinets I have read mixed things I am installing quality cabinets that the manufacturer said it not harm if I kept the design to a minimum pattern of heat help

WarmlyYours Responds...

That's a very interesting question but we'll need more information in order to help answer it. Please feel free to give us a call at 1-800-875-5285 and one of our technical support team members may be able to help get you a clear answer.

I need to replace a Kitec in floor heat system and would prefer to do it from the basement below but cannot find what " below the floor system " would be able to penetrate the plywood and grout/ cement above it . The existing Kitec system was installed from above and appears to be a fibrous /grout combination about one half in. thick.? Appreciate help at bcbm41@gmail.com

WarmlyYours Responds...

It sounds like you might be interested in a heating system that we call "between joist floor heating". Essentially it's heating mats that are attached to your subfloor from beneath and they radiate heat upwards into the room. While we don't sell those systems, we can recommend a brand called STEP WarmFloor. They're a great company and they should be able to help.

We have a large single level home in Northern Illinois that is designed to benefit from “solar gain” (sun shining directly onto a floor) during the cool and cold months. We currently have carpet but are researching different options. It seems wood, laminate, and LVT might fade in the long term from the sun exposure. It seems ceramic tile is the only option as we want to move from carpet. Without radiant heating, the floor and home will be ridiculously cold. I like the idea of having walking zones and living zones hooked up to a “smart” control system. The east side is always colder than the west side of the home. I would be interested in knowing what this type of heating would cost and how it can save some of the forced air heating expense. Any thoughts?

WarmlyYours Responds...

We would need more information to give you an accurate estimate of the cost of the system itself however, you could enter in a few details using our Quote Builder tool and it will give you a rough estimate of how much the system would cost: https://www.warmlyyours.com/floor-heating/quote-builder. But we can say that you could certainly set up a system with zoned heating (it would require the use of power modules in addition to a primary thermostat). We'd love to discuss this in greater detail along with going over how an electric floor heating system can help you save money on operating costs, so please feel free to chat us on the site or give us a call at 1-800-875-5285!

Is there any concern of damage with radiant heat under tile in a kitchen with very active children running and jumping around? My husband is concerned this will eventually lead to damaged tubes.

WarmlyYours Responds...

That shouldn't be an issue at all. Floor heating, when properly installed, is designed to withstand the rigors of family life no matter how active your kids are. We specialize in electric floor heating as well so there's even less chances for that to be damaged in the scenario you've outlined. Hope that helps!

I was wanting to have bare concrete floors. Is there something to put in while concrete is being poured to keep from having to install flooring on top?

WarmlyYours Responds...

Absolutely! Check out our Slab Heating Cables and Mats which can be embedded in your finished concrete floor! https://www.warmlyyours.com/floor-heating/concrete Send us an email at info@warmlyyours.com or use the chat tool in the bottom of your screen if you have any questions.

Would electric radiant heat make sense in an unheated sun room. I'm in NJ and was hoping it would allow us the extend the use of the sun room into early spring and late fall.

WarmlyYours Responds...

Generally speaking, electric floor heating can indeed be used to help extend the use of a sunroom by providing supplemental heat. There's a lot of variables to consider (like the size of the room and the level of insulation already in the room) but this is definitely a common use of electric floor heating. We even have a page of our website dedicated to it: https://www.warmlyyours.com/floor-heating/sunroom

I have an electric radiant heat system installed over a tile floor. Is it more or less efficient to keep it at a constant temperature or to schedule it to be low and only increase the temperature for the 4 hours we use it?

WarmlyYours Responds...

It will almost always be more efficient to use a programmable thermostat to turn the floor heating system on and off based on your schedule instead of running it at a constant temperature 24/7. When you use a programmable thermostat in this way, there will be a "warmup" period for a radiant heating system but it's very short for electric systems and is often built into the thermostat's programming. For example, if you want your floor temperature to be a certain temperature at 8 a.m., a good thermostat will actually turn the system on a bit before then to make sure the floor temperature is where it needs to be by the scheduled time.
