3 Types of Radiant Floor Heating

Radiant floors are heated either with electric resistance cables or hot water flowing inside the tubing. More information here on the different types of radiant heat and which is right for you. Here’s what you need to know about the different types of radiant floor heating:

1. Electric Systems

An electric radiant heating system is a supplemental heating tool that’s not meant to be the sole heat source for a room. With this system, the cables are attached to mats and installed over a subfloor. Also, there are radiant electric floor heating pads that can be installed under laminate and other floating floors, such as engineered hardwood.

2. Hydronic Systems

With a hydronic radiant heating system, you benefit from a system that heats the whole house. This system works by heating water with a boiler and dispersing it through tubing under floors. There are several ways to install the tubing, such as it can be within a concrete slab, applied over an existing slab in cement, or stapled under the subflooring. With this kind of system, you can choose almost any kind of finished flooring to go over the installed tubing.

3. Air Radiant Systems

An air radiant system uses heated air to transfer heat – however, it’s worth noting that air radiant systems tend to be the least efficient of the three types of systems. This is due to air having less capacity to carry and retain heat.

Radiant Floor Heating FAQs

Radiant floor heating systems warm a building directly through the floor. So, instead of heating and circulating air like other methods do, this type heats the floor which then radiates warmth upward. There are two main types of radiant floor systems: electric and hydronic, with air as a third, but less efficient consideration.

Radiant heating can be expensive to operate, however, it provides many advantages. The cost of installing a hydronic radiant floor heating system depends on the size of the home, the type of installation, and the floor covering. While the hydronic radiant system described above may more expensive, it will save money due to higher efficiency.

Your HVAC company will first perform an evaluation, and then create a layout to ensure optimal heat distribution within the room or building. Once the design is set, the floor surface is cleared and cleaned in preparation for the system. For hydronic systems, tubing is installed and connected to a water source. Meanwhile, for electric systems, electric mats or cables are positioned accordingly. After laying out the system, it is typically encased using a layer of concrete or a floor leveling compound. Once the system is securely in place, the next step involves connecting the hydronic tubes to a heating source, or in the case of electric systems, linking them to thermostats and power sources. Before the final flooring is laid down, the technicians test the system to ensure it heats the space correctly and evenly.

We recommend setting your radiant floor heating at about about 65-70 degrees. Typically, around 65 degrees is the most common temperature homeowners set a radiant floor heating system at.

You will not need your radiant heating system turned on. Turning it off can help save on energy costs and reduce unnecessary wear on the system. However, you typically don’t need to turn off your boiler completely. Many modern boilers are designed to be energy-efficient during warmer months, ensuring they operate at minimal levels just to supply hot water without heating the floors. Always consult your system’s manual or a local heating professional to make the best decision for your specific setup.

We recommend using a programmable thermostat to adjust your floor heating system’s temperature. This will be most cost-effective and energy-efficient than running your heat at a constant temperature 24/7.

Depending on the circumstance, turning your boiler off is fine. For example, if you want to turn it off in the summer, overnight, or while away on vacation. However, do not turn off your boiler during the winter as your pipes can freeze. Instead, utilize your timer to turn off your boiler during periods of no use.

Typically, your radiant heating system will feel neutral or warm to the touch. However, if your floor if starting to become hot, it is a sign that it needs to be repaired. The maximum temperature of your radiant heat should be around 130-140 degrees. There are two reasons your radiant heating system has become too hot. 1.) The temperature of the water in the system is too high. 2.) The radiant heat has become trapped.

In short, yes! Adjust your temperature to your liking to see what works for your home/your family’s preferences. If done correctly, turning your radiant heating down helps you to conserve on energy and cost.

First, make sure you keep your boiler clean. Also, be sure to check the boiler flame. You will also want to run the water occasionally to check to see how the boiler processes the water, and check to see if there is blockage or a leak. If so, call a professional to come and service your boiler. Other things to check for are glycol (check your pH level), and the water pressure. If you prefer to have a technician check these for you, let them know and be sure to ask them any questions you may have about your boiler system.
