Electric mat heating is quite cheap, economical and has very easy controls.
It is made up of 1 or more mats linked together with wires that pass a current through them until heat is omitted.
It is controlled by a thermostat linked to a probe in the floor that returns the temperature
It can be set to constant, timed or by clock

The majority of modern UFH systems are warm water systems, which integrate high tech plastic pipe either within or just below the floor.
Normally, water at a temperature of 47-62°C is circulated through this pipe and this warms the floor to a surface temperature of 25-28°C, about the same temperature as the palm of your hand.
The heat generated by radiators is transferred from a small surface area far hotter than the space it is heating. By comparison, UFH transfers heat from a very large surface area, which is only slightly warmer than the room.
Modern UFH systems are economical to run, virtually maintenance free and utilise effective controls. They provide the most comfortable all round warmth of any heating system.
In concrete floors, it is usual to set out the heating pipe or cable on top of insulation before the screed covers the pipe and completes the floor construction.
