ASK THE EXPERT


warm the floor covering. It’s a common misconception that electric systems can be used as a primary heat source and will heat an entire room and often it will be installed with this intention, only to not perform as epected. n reality, its only intended to keep surfaces warm and add comfort to the floor covering.


hile the majority of floor coverings can be used with underfloor heating, it is important to take care with certain coverings. or eample, not all carpet is suitable for all underfloor heating, particularly thicker carpets with high tog ratings.


Another key consideration is the type of project where the underfloor heating is required. If a renovation or retrofit project, where height build-up plays an important role in the decision, electric underfloor heating can be more suitable as a secondary heat source. It is additionally more suited where it is only being installed in a few select areas. On the other hand, for new builds or where the entire home is being heated, opt for a hydronic system.

hile electric underfloor heating systems are cheaper to install, water-fed systems have lower running costs.


ARE THERE DIFFERENT OPTIONS BASED ON THE TYPE OF FLOORING MATERIAL USED? Different floor heating systems are suitable for different types of flooring. Electric and hydronic systems work well with a variety of floor finishes such as tile, laminate, hardwood and vinyl. owever, some floorings, like carpet and polished concrete, reuire specific heating systems that are designed to accept those floor coverings.


CAN IT BE RETROFITTED INTO EXISTING HOMES?


Electric underfloor heating systems are ideally suited for renovation or retrofitting into an eisting property. Due to the low construction height, there is minimal build up requirements, with many systems being as low as just a few millimetres. These are perfect for scenarios where you may just want to add a bit more comfort to the room by warming the surface of the floor covering.


WHAT ARE THE MAINTENANCE REQUIREMENTS, AND ARE THERE ANY POTENTIAL CHALLENGES TO BE AWARE OF? aintenance reuirements for floor heating systems may vary depending on the type of system installed. Both electric and hydronic systems generally have lower maintenance needs. During the installation phase of electric systems, it is important to check the cables are tested before, during and after installation. Afterwards, ensure the thermostat works accurately and that it’s been set up to your requirements.


The main challenge associated with either system is identifying and repairing faults. Since both systems will be installed underneath a floor covering, fault finding should be carried out to identify any fault within the system, with removal of the floor tile being the last resort. It is recommended to consult with the manufacturer’s guidelines and seek professional advice for ongoing maintenance.
