Flexibility for Complex Spaces

The Loose Wire System’s unique advantage is the ability to easily install the cable where mats cannot go, providing customized heat output.

• Irregular Rooms: It is ideal for irregular-shaped rooms, such as bathrooms, where the cable can be easily installed around fixtures.
  
• Variable Power: The variable spacing of the cable allows the system power and heat output to be tailored to your property requirements.
  
• Energy Saving: By warming up and cooling down faster, before and after you use the room, the room is cooler when not in use, losing less heat and saving energy.

Note: For regularly shaped rooms, the Sticky Mat system offers a quicker and more precise installation alternative. Alternatively, for floor finishes other than tiles, the Foil Heater System utilizes a completely dry construction that does not require a levelling compound.
