What Is The Ideal Temperature For In-Floor Heating?

Have you recently installed in-floor heating and wondered what the ideal temperature to set it at is? Or are you someone thinking about getting in-floor heating but wants to learn what temperature the best setting is? Look no further! Continue reading below to get a definitive answer and learn more about different aspects/features of in-floor heating.

The ideal temperature for in-floor heating is 75° F (24° C). For a little range, anywhere between 74° F and 77° F sits in the sweet spot temperature-wise for in-floor heating. 

Some people will accept that for what it is, but for those curious as to why specifically 75° F is the ideal temperature, keep reading. We've looked into why this is the temperature to set your in-floor heating to so that you're comfortable and not too hot or cold.

Why Is 75° F The Ideal Temperature?

When you think of 75° F, you're probably thinking of peak summer temperatures, and for those that prefer fall/winter, you may be thinking that this is going to be too hot to handle. Fear not!

Seventy-five degrees Fahrenheit is a little below our skin temperature, which is just about 91°F. This means that the floor won't feel hot; it will feel comfortable to people. And ultimately, comfort is what one is seeking with in-floor heating. You don't want to be cold, and you don't want to be too hot, you want it just right.

Continue reading below to learn how warm the warm will feel with in-floor heating because, while the ideal temperature is 75°F, that isn't what the room is going to be.

How Warm Should In Floor Heating Feel?

So, as mentioned above, the ideal temperature for in-floor heating is 75° F, but rest assured that the whole room won't feel this way. As learned in a science class growing up, heat rises. So your feet will feel the hottest, but the temperature won't be as hot at eye level or above.

From the ground up, the temperature won't be as hot as it is from the source. So around eye level, people can expect a seven to ten-degree drop from the source. Going off of the ideal temperature, people will feel like it is about 68°F or a little more at eye level. Ceiling-wise, it'll be around 60°F. Again, you lose heat as it rises, and it will never be as hot as it is on the ground with in-floor heating.

Overall, you will feel the temperature assigned to the floor. But in the air, it should feel like a nice warm day at 68–70°F in the room itself.

How Long Should It Take In Floor Heating To Warm Up?

Although in-floor heating is known for quick heating up times, a few factors make it hard to give an exact amount of time it will take. Factors that affect this time are:

  • Size of the room
  • The insolation of the room
  • The floor finish used
  • The type of system and heat source

These four main factors impact how long it will take for a room to warm up.

Room Size

Obviously, if you installed in-floor heating for a smaller room such as a bathroom, it won't take as long as a decently sized living room. For example, a small to the medium-sized room may take 20 to 30 minutes to heat up, while a medium to large size room may take 40 minutes to an hour. These are not exact times but are used as examples to showcase there is going to be a difference based on size.


Insulation is how well your house retains heat. Do you find that you're cold often and feel like your heating is going to waste? Then you have a poorly insulated house. So, if you're in a poorly insulated space, it will take longer for the space to feel properly heated.

You should consider fixing the insulation in your house if this is a worry for you. On the other hand, if your house is well-insulated, then you won't have to worry about the room taking longer to heat up.

Floor Finish

Depending on what type of floor you have in the room you plan to have in-floor heating, the amount of time will vary. Tile and stone have proven to be the floor type that heats up the fastest due to their high thermal conductivity. This means that the heat from the in-floor heating system will transfer quickly to the surface of the floor.

On the other hand, one type of flooring to be aware of is carpets. If you have a carpeted room, you have to make sure that the material of the carpet doesn't act as an insulator. This will block the heat.

Type of System and Heat Source

The two types of heated floors are hydronic and electric. Hydronic simply means the floor is being heated by water, whereas electric is being heated by electricity.

The hydronic system circulates water from a boiler or water heater through tubing on the floor. This method is efficient for heating the entire house. For the electronic system, resistant wiring is zigzagged throughout the floor and is typically confined to one room/space.

What Is The Maximum Temperature For In Floor Heating?

While making the floor a little warmer isn't harmful, it is important to note the maximum temperature for in-floor heating. Looking through multiple sources, the top range to not go over is between 80° F and 85° F. But, a safe bet is to stay below 85°F, especially to avoid any unnecessary damage. At this point, you don't want to get too close to 90°F because our skin temperature is 91°F.

If you think about it, your feet are going to feel whatever temperature you set the floor at, so going above 85°F is going to be hot, and anything above could come too close or exceed our skin temperature.

Does In Floor Heating Need To Be Serviced?

Generally, in-floor heating is maintenance-free, but it is always recommended to get regular service maintenance so that the system stays top-notch. So, to keep everything in check, it is wise to get it serviced. This will ensure that you avoid any potential issues that could arise. Overall, though, you really shouldn't need to get it serviced.

Does In Floor Heating Heat The Entire Room?

Simply put, yes. In-floor heating covers the entire floor of the space chosen and heats consistently across the surface. You will not experience any cold spots due to the efficiency of in-floor heating; you'll even save money on your heating bill by utilizing in-floor heating.

As stated earlier, heat rises. Knowing this, you can expect the whole room that has in-floor heating to be warm. The heat will rise and make the room feel cozy and comfortable. Look above to the chart in this article to gain a visual.

Enjoy Your Heated Floors!

Armed with this information, you should feel at ease setting the temperature for your in-floor heating. If you're still someone on the fence about installing it in the first place, please note that it is safe and cost-efficient.
