What project is the Loose Wire System designed for?

  • The Warmup Loose Wire System (also known as DWSWire) is designed to suit irregularly shaped rooms and rooms with many fixtures, since the heating cable can simply be maneuvered on the subfloor around fixtures with ease. The spacing of the cable can be adjusted to your requirements in the desired power output and to the layout of the room you are installing the system in. The Loose Wire is ideal for installation under ceramic or natural stone tiled flooring.

Qualities Of The Loose Wire Heating Cable

  • At only 1.8mm, the heating cable is the thinnest on the market – so it does not raise the floor height visibly. The small cross-section of the heating element allows it to be installed without the need for a layer of a self-levelling screed. Install a Loose Wire System with a tile adhesive layer under tiles or with a self-levelling compound under other floor finishes.
  • Since installing Loose Wire does not require self-levelling screed, you do not lose any additional time or costs related to the drying of the system. Once the cable is laid down, the floor finish can be installed on top of it.
  • The Warmup Loose Wire System is suitable for all applications providing primary or secondary heating in all rooms or projects that adhere to Building Regulations.

Loose Wire Underfloor Heating Kit

  • Loose Wire is easy to install because it comes in the form of a kit. The kit contains all the necessary elements for the installation of the Loose Wire System.
    • Ultra-thin, 1.8mm cable multistrand. The dual-core heating cable is double insulated with an advanced fluoropolymer making it exceptionally durable and easy to tile over
    • Primer (for use of wooden subfloors)
    • Tape
    • Foam Roller
    • Installation manual
