Electric underfloor heating kits may be an excellent choice for heating your house, especially if you are remodeling. It is typically easier to install and smaller than standard water underfloor heating, so you won’t have to dig up your floor to place it. This can help you save both time and money.

While electric in-floor heating systems provide many advantages, there are certain disadvantages to consider before picking which type of underfloor heating system to employ in your house. This will depend on the sort of project and even the area where you intend to install underfloor heating.

Our comprehensive reference to electric underfloor heating kits will assist you in determining whether it is appropriate for your project.

What Are Electric In-Floor Heating Kits?

Depending on the system you choose, electric underfloor heating kits will normally include cables that may be hooked to a mat. Additionally, priming could be used to get the substrate ready for the mat to adhere to. Moreover, use tape to secure the mat or wires.

A thermostat will also be provided to control the system. Some systems will include backing boards for the wires to be laid on.

How Electric Underfloor Heating Kits Works

Electric underfloor heating kits heat an area by placing a thin heating wire beneath the surface of your floor. When turned on, the wires heat up and radiate through your floor surface, warming a room. The floor will also feel heated underfoot.

A separate underfloor heating thermostat is normally required to manage the system’s temperature as a whole or in zones.

Where Do Electric In-floor Heating Kits Work Best?

Kitchens and bathrooms are often the ideal sites for electric underfloor heating kits. These rooms often feature hard flooring, which can be chilly to the touch, especially while walking bare feet. Kitchens and bathrooms sometimes have a lot of fixtures, so space for extra radiators is restricted.

It is feasible to have electric in-floor heating kits with carpet, but you must install a certain type of carpet for the heat to radiate through adequately. Another alternative is wood flooring with underfloor heating; however, some varieties of wood flooring enable heat to seep through better than others.

One advantage of electric underfloor heating kits over water is that it heats up faster. As a result, it may be turned on just before entering the room. The temperature rises much more slowly in water systems.

To maximize the effectiveness of the underfloor heating kits, devices such as timers, light relays, motion sensors, and hot water sensors can be employed.

Additionally, these kits are also used for electric snow melting systems.

Advantages and Disadvantages of Electric Underfloor Heating Kits

As with every piece of equipment, electric underfloor heating kits have pros and cons.

Advantages of electric underfloor heating

  • Electric underfloor heating is substantially thinner and takes up much less area than wet underfloor heating. A supporting board is likely required for insulation to minimize heat loss downwards, but the wires are considerably thinner, and the entire system can sit closer to the surface.
  • Because the system is closer to the surface, it can react much faster.
  • This might be excellent if you only require a tiny amount of heat for a short time, such as in an ensuite bathroom.
  • With electric underfloor heating, there is no need for a manifold. This implies that it is simple to install in a single room without causing any interruption to adjacent areas.

Disadvantages of electric underfloor heating

  • Electric in-floor heating kits may cause hot patches in a room with a second heat source, such as a range stove or wood fire, or in a south-facing room that might benefit from solar gain.
  • Electric underfloor heating kits can also be costly to operate if not properly maintained. Whatever heat you try to generate on your floor, the electric system will cost more if left on for extended periods.
  • If you want short bursts of heat and are not attempting to heat the fabric of the structure, an electric solution may be the best alternative.
  • In the case of a system failure, such as a wire breaking, determining the location of the break to fix it is extremely difficult. The leak would be visible on a wet underfloor heating system, and while it would be inconvenient, it is repairable.

What Is the Price of Electric Underfloor Heating?

There are several forms of electric underfloor heating, each with its own set of expenses for systems and installation:

  • Thin mesh systems: $72/m2 to $80/m2
  • Quick matting system: $90/m2 to $100/m2
  • Budget systems: $24/m2
  • Foil systems suited under the carpet: $60/m2 to $80/m2
  • Loose wire system: $80/m2 to $90/m2

What Does Electric Underfloor Heating Cost to Run?

Electricity now costs roughly $0.11 per unit, and a unit is one kilowatt (kW) for one hour; hence it is referred to as a kilowatt per hour (kWh).

If your electric underfloor heating is 125W per square meter, you will consume $0.11 every hour the system turns on for every eight square meters of floor.

However, remember that the system is not on all day because the thermostat only calls for heat when needed, making it simple to keep your expenses under control.

Best Electric Underfloor Heating Kits

Electric underfloor heating kits come in various forms; here’s how to find the best one for your needs.

Best Electric Underfloor Heating for Tiled Surfaces

Choose a thin electric underfloor heating system, which is less than 2mm thick overall and includes wires coupled to a fine mesh. Since the tile glue is subsequently placed directly to the mesh and the heater essentially rests in the adhesive layer, the floor levels are not elevated.

Best Electric Underfloor Heating for Fast Installation

A matting system that decouples the tiles from the flooring can be employed. The wires are placed into prefabricated cut-outs in the matting set on the floor.

The glue is then applied to the matting, and because it is not put directly into the flooring, the possibility of subsequent seasonal cracking is reduced.

Best Electric Underfloor Heating Kits on a Budget

The most affordable electric underfloor heating kit solution is a cable embedded in a screed. This system includes larger cables and allows you to alter the floor finish without breaking the wires. The system reacts slowly and should be built for long-term room heating rather than immediate job heating.

Best Electric Underfloor Heating for Finished Rooms

Soft finishes, such as vinyl, carpets and laminate, and other floating floors, may be difficult to install, and foil-type systems are meant to address this issue. This approach doesn’t necessitate the use of a screed.

Best Electric Underfloor Heating for Irregular Rooms

A loose wire system is suitable if the space has irregular forms or permanent fixtures. The heater is a long-lasting flexible cable that is adhered to the backing boards and immersed in leveling compound or glue.

The installation is a little more complex, but the product offers flexibility for a lot more creative arrangement.

Should I Leave My Underfloor Heating System On?

Electric underfloor heating is typically left on all of the time. Still, it is not truly active all of the time since the thermostatic controller manages when and how much heat is necessary.

You may also program timers into the system to ensure that the controller does not seek heat when the room is empty.

How Hot Does an Electric In-floor Heating Kit Get?

The floor’s surface temperature will be measured to evaluate the heat presented by an underfloor heating system. The surface temperature of a hard surface, such as ceramic tiles, will be roughly 29°C.

Softer floor coverings, such as engineered wood or specialty flooring coverings, will only reach about 27°C to avoid cracking and discoloration. This element must be planned; therefore, it is critical to determine the surface materials early on.

What Flooring Works With Electric Underfloor Heating Kits?

With any underfloor heating, the tougher the surface of the floor finish, the better. As a result, polished concrete and ceramic tiles are excellent flooring options for electric underfloor heating kits. Additionally, engineered flooring is acceptable (Avoid using solid wood since it will shrink as it dries in the heat.).

Carpets may be difficult to clean. Carpets must have a tog value of less than 2.5 to operate, but they may also serve as a breeding habitat for house mites and dust mites due to the lengthy periods of background heat.

Underfloor heating kits may be put under both suspended and wooden floors, but a specific backing board must be used to ensure that the wires do not damage any of the timbers in the floor and that any movement does not harm the wires.

What Flooring is Unsuitable for Electric Underfloor Heating Kits?

Any flooring that prevents heat from entering the room should be avoided, and any floor surface that contains heat-sensitive adhesives or dyes must be avoided or, at the very least, monitored. It’s important to buy from companies offering warranties and guarantees, which can help with problem-solving if a failure occurs.
