What You Need To Know About Ditra Heat - Is A Dedicated Circuit Required?

With a Ditra-Heat floor heating system, you can have evenly heated rooms, but which electrical source should you use to heat the floor?

A dedicated circuit is required for a Ditra-Heat floor heating system. If your electrical panel does not have a dedicated circuit provision, you must ensure that your current circuit breaker can handle the additional power required to heat the floor.

A floor heating system requires a dedicated circuit. Continue reading to find out why and whether there are any alternatives. The advantages and disadvantages of this floor heating system are discussed, as well as whether it is safe and how much it costs to install.

Is A Dedicated Circuit Required For Ditra-Heat?

A dedicated circuit is typically used with high-power appliances such as refrigerators, dryers, and dishwashers. This category also includes the Ditra-Heat floor heating system. The energy received by the heating system should not be shared with any other appliance.

A dedicated circuit delivers enough power to the floor, at least 220 volts, without the risk of overloading the system. This is greater than the standard 120-volt wall receptacle.

A dedicated circuit ensures that the wiring on your floor does not consume more power than it should.

This is what you risk if you use a non-dedicated circuit, which can lead to wire overheating and a fire.

Can A Dedicated Circuit Be Added ?

To operate high-power appliances, the National Electrical Code requires a dedicated circuit. In this case, your heated floor is powered by high voltage. If you intend to install a heated floor, a dedicated circuit can be added.

Installing one costs around $700 on average. A ground-fault circuit interrupter (GFCI) circuit breaker, cable clamp, and electrical staples can all cost between $100 and $150.

Expect to pay $50 to $100 per hour for labor, with a total cost of $550 to $970 for the entire job.

Is Ditra-Heat Flooring Dangerous?

This is most likely a question you have. Underfloor heating systems are extremely secure. However, if the system is not properly installed, you will endanger your own safety. That is why you will require the services of a professional to install it in your home.

If you are considering purchasing an older home, you should proceed with caution. This is due to the fact that its circuitry may be incapable of handling the load of an underfloor heating system. You’ll need to replace the wiring and fuses. Otherwise, your new flooring may pose a fire risk.

Not cutting or modifying the cables is one of the installation instructions that must be followed.

A single cable cannot be used to heat more than one room. In other words, do not run the cable through the wall and into another room.

Instead, install the cable in one room and, if necessary, another cable in another. Heating cables should not be overlapping or installed beneath fixtures like vanities and kitchen cabinets.

When operating the Ditra floor heating system, you must avoid placing mats or flat furniture over the temperature sensors under the floor. Avoid putting pillows, mattresses, or futons on top of the sensors.

These items can raise the temperature, interfere with thermostat readings, and cause floor damage.

In a nutshell, Ditra floor heating should be installed correctly, so hiring a professional is recommended. You should also follow the guidelines provided by your dealer for your own safety.

The Advantages Of Underfloor Heating

Walking on a heated floor in the winter can be both comfortable and enjoyable. The following are some of the advantages of this type of floor heating system:

Room That Is Evenly Heated
Because the heating coils are evenly distributed throughout the floor, the room is evenly heated.

This differs from vent heating in that the warmest areas are those closest to the vents. This means that there will be areas of your room that aren’t properly heated.

Heating That Is Quiet
With a heated floor, you can enjoy peace and quiet. This might not be the case with a furnace that makes noise while running.

After you install your floor heating system, it should last at least 20 years with no maintenance. However, as previously stated, this is subject to proper installation.

This flooring is versatile because it is appropriate for people who suffer from allergies and other respiratory conditions. In contrast to other heating methods, dust, debris, and particles are not blown around the room, reducing allergic reactions.

Reduced Energy Bills
Heated floors can help you save money on energy bills when compared to heating systems that blow warm air through a vent.

To begin with, there is no need to increase the heat to cover the cold areas because there are none. Instead, the heat is distributed evenly throughout the room. Second, there is no ductwork that can crack or become damaged, allowing heat to escape.

The Downsides Of Underfloor Heating

The following are some disadvantages of Ditra heated floors:

The Floor Must Be Replaced
Only a new floor can have an underfloor heating system installed. So, if you want to install it on an existing floor, you’ll have to tear it up first.

The floor can then be installed. The most common is tile. As a result, the best time to install this heating system is during a home renovation.

Expensive Installation
The initial cost of installing a heated floor is higher than the cost of installing most other heating systems. You should budget between $10 and $20 per square foot. Labor for a few hours of work could cost between $200 and $250.

In addition to hiring a technician to install the floor, you will need an electrician to connect the floor to your home’s electrical system. You should expect to pay between $40 and $120 per hour for this service, with a total cost of $150 to $600.

Despite the fact that these costs are for medium or smaller projects, you will save money on energy in the long run.

The Reason For Ditra Heat’s Uncoupling

Floors experience expansion and contraction, which can cause cracking. This is why Ditra-Heat employs uncoupling technology. It prevents the subfloor from moving, which can cause the floor above to crack.

Furthermore, the system’s composition is waterproof, protecting the substrate from moisture. Moisture can escape through the spaces beneath the floor, keeping the substrate as dry as possible. As a result, the flooring above is not damaged.


Because it distributes heat throughout a room, Ditra-Heat is a one-time solution for heating your home.

This is one of several advantages of using a heated flooring system. However, there are some disadvantages that you should be aware of before installing the system.

Installing the system will necessitate the use of a dedicated circuit. If you don’t have one, make sure your circuit breaker can handle the power load required by the system. A dedicated circuit can be added as well.
