12 best radiant underfloor heats

Radiant underfloor heating is a modern and efficient method of heating indoor spaces, primarily used in residential and commercial buildings. This type of heating system is often associated with comfort, energy efficiency, and evenly distributed warmth throughout a room. Here's what you need to know about radiant underfloor heating:

How It Works: Radiant underfloor heating systems work by installing heating elements, usually electric wires or water pipes, beneath the floor surface. These elements emit heat, which then rises and warms the room from the floor up. This radiant heat transfer is more efficient and comfortable compared to traditional forced-air heating systems.
Types of Radiant Underfloor Heating:
- Electric Radiant Heating: Electric systems use heating cables or mats installed beneath the flooring. They are relatively easy to install and are suitable for retrofitting into existing structures.Electric systems are often used in small areas like bathrooms or kitchens.
- Hydronic Radiant Heating: Hydronic systems circulate heated water through a network of pipes installed beneath the floor. They are typically more energy-efficient than electric systems and are commonly used for heating larger areas or entire buildings. They can be connected to various heat sources, including boilers and solar panels.
Benefits:
- Even Heating: Radiant underfloor heating provides consistent warmth across the entire floor, eliminating cold spots and drafts commonly associated with forced-air systems.
- Energy Efficiency: Hydronic systems, in particular, can be highly energy-efficient, as they can be powered by various heat sources, including energy-efficient boilers and renewable energy systems.
- Space Savings: Radiant systems don't require the installation of bulky radiators or vents, which can free up space and provide more design flexibility.
- Comfort: Walking on a warm floor can be very comfortable, and radiant heating minimizes the circulation of dust and allergens compared to forced-air systems.
- Zoning: Radiant systems can be divided into zones, allowing for precise control of heating in different areas of a building. This can lead to further energy savings.
Installation: Installing radiant underfloor heating requires careful planning and is typically done during construction or major renovation projects. The type of flooring material and insulation used can affect the system's performance.
Maintenance: Radiant underfloor heating systems are generally low maintenance. Electric systems may require occasional inspections for damaged cables, while hydronic systems may need periodic maintenance of boilers and pumps.
Cost: The cost of installing radiant underfloor heating can vary depending on factors such as the type of system, the size of the area to be heated, and the complexity of the installation. However, over time, energy savings and increased comfort can offset the initial investment.

Radiant underfloor heating is a popular choice for homeowners and building owners looking for efficient, comfortable, and space-saving heating solutions. It's important to consult with professionals experienced in installing these systems to ensure they are properly designed and installed for optimal performance.

User questions & answers

Question:	Can thos be cut to fit room size
Answer:	No, they have a special termination at the end and the cable can not be cut, it would be useless.
Question:	I'm looking for something to put actually under the floor, between the joists. will this work
Answer:	I’m not sure why you would do that, but if you are installing under subfloor NO.
Question:	How hot do the wires get
Answer:	The wires do not get very hot they are insulated also the heat is radiant so when the Floor gets warm it stays warm
Question:	Will this work with peel and stick laminate flooring? I want to put this in truck camper
Answer:	Stick in peel is the glue so it will not stay glued to it and it will want to move it is only good with ceramic tile
Question:	I need 24" x 60".. Can I route the last one feet wire along the side to increase the width to 24" and keep the length to
Answer:	You can loosen the heating element from the mesh and put along side the mat keeping it at 3" spacing.
Question:	I am planning to install wooden floor (hardwood or laminate) in my bathroom. Can I use this system to heat wooden floors or is is for tiles only
Answer:	The floor heating system can be installed under laminate or engineered wood floors, but not a traditional wood floor in which you are nailing down the floor because of the risk of putting a nail through the wire. Regardless of the flooring type, the floor heating system must be completely embedded in a polymer modified cement based mortar.
Question:	I have a concrete slab that I would like to add electric floor heating and tile over it. How do I avoid moisture build up with this product
Answer:	You need to seal your concrete floor! Theres a great product on amazon here that gets down into concrete and seals up everything--it even pushes dirt and moisture out as its sealing! and you just spray it on. Its advertised to block radon, but its all the same different of sealing concrete (will make moisture barrier, block radon, etc.) I think its just called "Radonseal" and its in a big bucket; you'll also need a 1 gallon sprayer, they run about ten bucks. I would seal it before installing this product, as you'll get a lot more out of it. You'll still want to cover it with something so it can distribute its heat (like put in thinset or something like that) it doesn't have to be fancy tile. I did mine in thinset and threw a rug over it to make a warm place for my pets while i'm at work.
Question:	Can this be used when installing a drop-in tub to keep bath water warm
Answer:	No, but Kohler has a tub that has a built in heating element on the portion where you lean up against. I don't know how well it would heat the water, but I bet it would be nice.

Floor Heating Mat

The Electric Floor Heating Mat consists of a mat with the cable heating elements pre-spaced 3" within the mat. Simply unroll the floor heating mat with the cold lead running up the wall to the electrical box. These heating systems are ideal for rectangular or square areas with right angles. You can manipulate the mat to fit the desired heating area by using the turning techniques shown below. The white fiberglass mesh may be cut to flip and turn the mat. The RED HEATING ELEMENT CAN NOT BE CUT, so be sure to accurately measure the space you are heating.

Installation Monitor

The Installation Monitor can help give you peace of mind while installing the floor warming system. Connect the system leads to the monitor prior to installation. The monitor will "scream" a warning in the event the heating element is cut or damaged allowing you to make any necessary repairs before the heating system is embedded in mortar. If the alarm sounds, stop work and consult the operation manual. We still recommend checking the ohms of the floor heating system with a multimeter before, during, and after installation.

Red light and alarm indicates lead wires have come loose from the terminals or damage has occurred to the heating system
A white light indicates the monitor is operating
Can monitor up to 3 systems at one time when they are temporarily connected in series

User questions & answers

Question:	Do you have installation instructions you can send
Answer:	Wouldn't be the same thickness as if with two other filters? I don't see much choice if you want to use this or other pouches. Buy it on Amazon and return it if it does not suit your needs.
Question:	I need a 25sqft and a 20sqft. Do you have any 20 sqft systems? 120 volt similar to the 25 sqft system you have here
Answer:	2.25" maximum; a little less if it's a thick belt. (The other answer here of 2.5" is a bit off -- it was probably a measurement of the outside rather than inside of the loop. See photo in my review with ruler.)
Question:	Can the end of the heating wire be cut if I don't need all of it
Answer:	No. It works with 1/2 inch pvc/pipe thread
