Illustrative rendering. The selected model’s instructions set the complete floor build-up.
Floor heating
AvailableDry film under wood. Wet film under tile. One thin layer that warms its whole surface at once, planned with the floor and the suite’s electrical design.
Floor construction
A floating finish, heating film and supporting layers, separated to explain this construction.
The finish sits above the heating film, insulation and supporting floor. The model, flooring and project determine the construction and its build-up height.

The layer view separates film, insulation and the supporting floor. Review electrical connections and controls with that assembly.
Heating panels, supply leads, floor sensing and controls are planned with the chosen finish and electrical design.
Illustrative views. Construction follows the selected model; connections and protection follow the project’s electrical design.
Build from the floor up
Dry and wet installations use separate floor-film products. Start with the finish, supporting floor and available height; then specify the heating model and complete assembly.
Dry installation
The dry film lies straight beneath a floating wood or laminate floor, above the specified insulation. No mortar, no pour, no waiting.
Plan space for the supply leads and sensor. Finish compatibility and operating limits follow the selected model and flooring instructions.
Wet installation
A separate wet film is built into the covered floor beneath tile and stone, for bathrooms, kitchens and entrances. Its own construction and instructions apply.
The dry film’s construction and handling instructions do not carry over to this system.
The selected model’s instructions and project design establish the complete build-up.
Connections and control
The film’s supply leads and the floor sensor do different jobs. Plan both routes before the floor is closed.
Power and sensing take separate paths
Individual panel leads carry power to the film. They are not a routed heating cable.
The panel leads meet the planned electrical connections.
Sets temperature and a programmed schedule for the selected control arrangement.
A separate sensing lead provides floor-temperature feedback.
Connection overview. Circuit, protection and routing follow the project’s electrical design.
Panel sizes, coverage and individual lead routes are set out for the room. Junction-box locations and any conduits belong to the electrical design.
A compatible relay can extend a thermostat’s controlled load. It follows the thermostat; it does not create another independently programmed zone. Capacity is checked from electrical ratings, not the number of panels or wires.

Thin, electric, silent and hidden. Here is how the film sets up against the systems people ask about most, then all five side by side.

Illustrations show where heat starts in each system. Colour is not a temperature reading, and the pictures are not to scale.

| Where the heat starts | A conductive film beneath the floor finish. | An electric cable routed beneath the floor finish. | A furnace heats air; ducts and registers distribute it. | A wall-base element warms passing room air. | Heated water circulates through tubing beneath the floor. | ||
| What gets installed | Dry film: beneath a compatible floating floor. Wet film: a separate, covered assembly. | Cable and compatible floor layers. Some systems use mortar and an uncoupling membrane; a new slab is not always needed. | A furnace, supply and return ducts, registers and controls. Existing ductwork needs assessment. | Wall-mounted heaters, electrical circuits and controls, with clear space for airflow. | Floor tubing, a heat source, circulation equipment and controls. Embedded and retrofit panel systems exist. | ||
| Equipment & space | No boiler, pumps, manifolds or ducts. A supply circuit, thermostat and floor sensor per room or zone. | No central plant. A supply circuit, thermostat and floor sensor per room or zone. | A furnace or air handler in a mechanical space, plus supply and return ducts through the building. | No central plant. Each heater takes wall space and needs clear airflow around it. | A boiler or heat pump, pumps and manifolds, usually in a mechanical room, plus tubing in each floor. | ||
| What you hear | Nothing from the film. No fan, no pump, no moving parts in the floor. | Nothing from the cable. No fan or pump in the floor. | The blower and air moving through registers when the system runs. | Usually quiet; some units tick as they warm and cool. | Quiet in the room. Pumps and the heat source run in the mechanical space. | ||
| What shapes energy use | Electric resistance heating. Consumption depends on the room’s heat loss, floor assembly, controls and use. | Electric resistance heating. Consumption depends on the room’s heat loss, floor assembly, controls and use. | Fuel or electricity for the selected furnace, plus the blower. Equipment and duct losses matter. | Electric resistance heating. Consumption depends on the room’s heat loss, controls and use. | Energy for the selected heat source and circulation pump. Boiler or heat-pump performance matters. | Both use electric resistance heating. Consumption depends on the room’s heat loss, floor assembly, controls and use. | |
| Access & maintenance | Controls and connections need planned access. Work on concealed film depends on the floor and fault location. | Controls are accessible; a concealed cable repair can involve the floor finish. Follow the selected system’s repair procedure. | Filters, blower, furnace and ductwork need service access. Maintenance follows the equipment instructions. | The heater is accessible at the wall. Keep airflow openings clear; electrical repairs need qualified service. | Service pumps and the heat source as specified. Access to concealed tubing depends on the floor assembly. | ||
The film and cable CG show system layout. Descriptions explain the other systems. Neither establishes measured heat output. Floor layers and connections depend on the selected product.
GreenCitizen’s assembly descriptions follow its supplied product documents. Dry and wet films are separate products. The references below describe other system types; none tests GreenCitizen’s performance. Drawings do not replace model-specific installation instructions.

From plan to installation
Confirm the room plan, construction and electrical design together. Installation and checks follow the selected model’s instructions.
What to ask before specifyingDesigner and project team: room dimensions, heat requirement, supporting floor, insulation, finish and available height.
Electrical contractor: supply, panel leads, junction boxes, sensing, controls and protection, with the applicable model records.
Owner and installer: control locations, supported scheduling and the operating limits of the floor finish.
A little more clarity
No. The dry-installation product is planned beneath compatible floating flooring. The wet-installation product has its own concrete or screed-covered construction. Each has separate model instructions; neither assembly is a template for the other.
Start with your chosen finish, then select the appropriate dry- or wet-installation product. The heating model’s instructions and the flooring manufacturer’s requirements determine compatibility, construction and operating limits.
Both. In a new build the floor is drawn around the heating layer from the start. In a renovation the available build-up height, the insulation and the electrical supply set what the floor can take.
A project can be planned around one room. Confirm its heat requirement, available heating area, circuit and controls with the project team.
That is a calculation for your building, not a figure we publish. The room’s heat loss, the climate, the electrical tariff and the schedule set it. Ask for an estimate for your project.
