HILOflex 18 is a very thin twin conductor heating cable of 18W/m output, with high-temperature resistant conductor insulation that makes heating cable thin and strong. Made by Scandinavian traditions, heating cable has a one-point connection that makes the underfloor heating cable installation quick & easy.
HILO flex 18 is the perfect choice for all floor types in new or renovated homes. The heating cable can be directly laid in/on a concrete base or on old tiles in the bathroom, kitchen, living room, children’s room, bedroom, and other premises under tiles, marble, granite or carpet, and vinyl flooring.
HILØ heating cable as well can be used in outdoor applications for frost protection of steps under the tiles or stone directly laying cable in tile adhesive layer.
Made by Scandinavian traditions
HILØ priorities are innovative products that save energy and are easy to install. HILOflex 18 is a high-quality heating cable made by Scandinavian traditions, combining the best innovations and environment-friendly design.
HILOflex 18 heating cable is very thin, only 4.4 mm diameter, so thin and strong that it can be laid directly on the new or renovated floors and for cold zone heating by the large windows. The heating cable is so thin that it does not increase floor level and you will notice just a comfortable warmth.
HILOflex 18 ensures high reliability with innovative high-temperature resistant twin conductors’ insulation, making it very strong and durable. In addition, it is energy-efficient and delivers comfort with a quick heat up and even floor heat distribution. HILOflex 18 is highly flexible and easily placed around any area or floor layout. HILØ thin heating cable has “memory” and is used to install a heating system within thin or thick floor constructions.
HILOflex 18 heating cable is easy to install and maintenance-free. One-point connection cable installation is simple and faster using installation tape. In addition, HILOfast installation tape helps to fix the heating cable on the floor at an even distance to ensure even heat distribution in the room.
You will complete the task fast, just in a few simple steps. First, lay the HILOflex 18 on the floor, easily fix it to the HILOfast, and simply connect to the thermostat.
Once installing HILOflex 18, you can forget about maintenance costs and enjoy a warm floor at your home.
The high-quality HILOflex 18 heating cable has a 12-year warranty for your peace of mind. It is designed with protective aluminium foil and a multiwire screen, combined with twin conductor high-temperature resistant insulation technology to ensure high cable quality and better indoor climate for a long-lasting system that runs over 30 years.
HILOflex 18 is equipped with 100% protective aluminium and a multiwire screen connected to the earth of electrical installation. In case of unexpected heating cable damage, the system shuts down immediately without any risk.
We care about your safety and environment, so we made HILOflex 18 halogen-free. Safe for you and good for the environment.

The HILOfast installation tape is necessary to fix the heating cable at a C-C distance, to install the heating cable evenly in the room, and ensure even heating distribution through the area.
The distance between installation tapes should be 0,3-0,5m.
The minimal distance between the cables should be 5 cm. For example, when installing the HILOflex 10 heating cable, the distance usually is 8-10 cm, and for the HILOflex 18, the distance is 12-15 cm. The distance between heating cables depends on the installed power output per square meter.
The C-C distance between the heating cables should be calculated as follows:
C-C = Heated area (m²)/ Cable length (m)
C-C= 10 m² / 69m = 0,145m = 14,5cm.
The HILOfast tape has hooks with a distance of 2 cm, so after calculating the distance between the cables, you can calculate to which hook the heating cable should be attached.
The heating cable HILOflex 10 and HILOflex 18 differ in power output per meter. The HILOflex 10 heating cable output is 10W/m and HILOflex 18 – 18W/m.
No, the heating cable thickness does not affect the heating of the cable. Thin floor heating cables are “new generation” heating cables with temperature resistant fluoropolymer insulation. They are stronger, flexible, durable, lighter and faster, and easier to install.
The heating cable has a braided copper screen and an additional aluminium foil, so it stays in the folded position when bent. As a result, installing the heating cable with “memory” is easier and faster, also it saves installation time and cost.
Usually, one heating cable is not enough in a large area or room. Therefore, two or three heating cables can be installed and connected to one or more thermostats.
Two cables can be connected to one thermostat, but the total power of heating cables should not exceed 14 A – 16A, the power controlled by the thermostat. The total installed power should not exceed 3.2kW – 3.6kW accordingly.
A thin floor heating cable is better than a thick one. A thin heating cable is a new generation cable, where each conductor core is insulated individually with a high-temperature fluoropolymer. These cables are of high quality, durable and reliable.
Meanwhile, the thick heating cable insulation is polyethene, which maintains only lower temperatures.
Yes, it is possible to extend the connection cable. For example, the connection cable can be extended up to 20 meters with 3×2,5mm² power cable.
Yes, the floor temperature sensor cable can be extended up to 50 m with a copper cable of not less than 2×15 mm². Please contact the HILO Heat specialist if you need to extend the roof and ground sensors.
The maximum thickness depends on the surface of the flooring:
- for wood surfaces – 20-30 mm;
- for laminates – standard thicknesses according to their technical characteristics;
Usually, there are no restrictions on tile and carpeting thickness.
Please note that most laminates and carpeting are designed to use for heated floors.
