Electric Underfloor Heating Mitchells Plain | Bathroom, Kitchen, Living Areas

About Underfloor Heating (Electric) in Mitchells Plain

Electric underfloor heating provides luxurious, even warmth from the floor up, making cold tiles comfortable underfoot during the Western Cape winter months. Unlike radiators and heaters that create hot spots and cold zones, underfloor heating distributes warmth evenly across the entire floor surface for consistent, comfortable temperatures throughout the room.

Abacas Solution installs electric underfloor heating systems in Mitchells Plain for bathrooms, kitchens, living areas, and bedrooms. We install both heating mat systems (pre-spaced cables on a mesh for quick installation under tiles) and loose cable systems (for irregularly shaped rooms or areas with obstacles). Both types are installed beneath the floor finish and are completely invisible once the floor is tiled.

Our installation includes laying the heating elements on insulation board to direct heat upwards, connecting the cables to a dedicated circuit with a programmable thermostat, installing a floor temperature sensor, and testing the system before tiling. The programmable thermostat allows you to set heating schedules, so the floor is warm when you wake up and when you come home, without running 24/7. For bathrooms, we typically install a mat covering 60-80% of the free floor area (avoiding under fixtures). Our registered electricians ensure all wiring complies with SANS 10142-1 and the heating system manufacturer's installation requirements.

This is one of several specialist services we offer under commercial & specialty electrical in Mitchells Plain. As part of our Mitchells Plain electrical team, we bring over 25 years of hands-on experience to every job.

When to Call for Underfloor Heating (Electric)

Call if you are renovating a bathroom or kitchen and want underfloor heating installed before tiling, if you are building a new home and want to include heated floors, if you want to add warmth to cold tile floors in existing rooms (requires retiling), or if you need the electrical connection for an underfloor heating system that has been laid by your tiler.

Our Underfloor Heating (Electric) Process

1

Floor Area Measurement

We measure the floor area to be heated, identify fixture positions to avoid, and select the correct heating mat or cable system for the space.

2

Preparation

We install insulation boards, plan the cable layout, and run the thermostat cable and sensor cable to the wall-mounted thermostat position.

3

Heating Element Installation

We lay the heating mat or cable in the planned pattern, secure it to the subfloor, and connect the floor temperature sensor.

4

Electrical Connection and Testing

We wire the heating circuit to a dedicated breaker with earth leakage protection, install and programme the thermostat, and test the system before tiling begins.

Property owners in Mitchells Plain often combine underfloor heating (electric) with three-phase power installation in Mitchells Plain and prepaid meter installation. We handle everything, so you only need one call.

Safety & Compliance

Electric underfloor heating must be installed on a dedicated circuit with earth leakage protection (RCD) per SANS 10142-1. The heating cable must not be cut, crossed, or overlapped, as this causes hot spots and cable failure. A floor temperature sensor is mandatory to prevent overheating. The system must be tested before tiling, as cable damage during installation cannot be repaired once tiles are laid. Only a registered electrician should make the electrical connections.

Underfloor Heating (Electric) Cost in Mitchells Plain

Electric underfloor heating costs depend on the floor area and system type. Heating mats for a standard bathroom (4-6m2) cost R3,000-R6,000 for the mat and thermostat, plus R2,000-R4,000 for electrical installation. Larger living areas (15-25m2) cost R8,000-R15,000 for mats and R3,000-R5,000 for installation. Running costs are approximately R3-R5 per square metre per month with a thermostat-controlled schedule.

Frequently Asked Questions

How much does electric underfloor heating cost to run in Mitchells Plain?

With a programmable thermostat, a typical bathroom costs R50-R100 per month to heat. A larger living area costs R150-R400 per month. The thermostat ensures the system only runs when needed, keeping costs manageable.

Can underfloor heating be installed under any floor type?

Electric underfloor heating works best under tile, stone, and engineered wood floors. It is not recommended under solid hardwood or thick carpet, which insulate the heat and reduce efficiency. We advise on compatibility with your chosen floor finish.

Is underfloor heating installed before or after tiling?

Before. The heating mats or cables are laid on the subfloor, tested electrically, and then the tiles are laid on top. This is why underfloor heating is best installed during a renovation or new build. Retrofitting requires removing existing floor tiles.

How long does the floor take to warm up?

Electric underfloor heating reaches comfortable temperature in 20-45 minutes depending on the floor type and insulation. This is why a programmable thermostat is valuable: set it to turn on 30 minutes before you wake up, and the floor is warm when you step out of bed.

Can underfloor heating replace other heating in Mitchells Plain?

In well-insulated rooms, underfloor heating can be the sole heat source. In older, less-insulated properties, it works best as supplementary heating for tile floors, combined with other heating for the room. We assess your room and advise on the best approach.
