Under Tile Heating dominates the market in terms of warming hard flooring (most flooring types). Pre-programmed control warms the room before you arrive. The Investment is small and operational costs are low because it is installed close to the surface and therefore responds quickly.
In-Concrete Electric Storage Heating is recommended for larger areas (>50 M²), especially for finished concrete flooring. Off-peak electric night tariffs (If available) can be used to store heat overnight in the concrete foundations (new build), or an overlay to an existing substrate (> 25mm) to be released during the day.
For very large areas and if budget allows you can consider Hydronic water Fed Systems.
