Electric floor heating
Electric floor heating is the modern and clean way of heating.  
WebHeat systems meet today’s requirements with regard to comfort and energy efficiency. The heating mat is laid just under the (tile) floor, so that the heating time is minimal. The heating capacity of 160 W / m² guarantees a quick and even heating of your floor. WebHeat Floor is excellent for use under tile floors, natural stone, laminate and wooden floors. Discuss the installation of WebHeat Floor in advance with your floor supplier for optimum coordination of your floor finish. 
You must order the clock thermostat separately.
