Radiant heating Types of Radiant Heating Underfloor heating Electric systems
 Electric systems are made of electric cables that are laid underneath the floor. Electricity is then used to heat the cables, and this type of system can be turned on or off much faster than a hot water system. However, these systems are often more expensive than hot water systems because of the high prices of electricity, especially if the hot water system includes the use of solar thermal energy. The high cost of an electric heating system can be reduced if the floor can be set to heat during non-peak hours, such as late at night, and is left turned off during the day. Electric systems are also less environmentally friendly because electricity is usually produced by burning fossil fuels, which increases carbon emissions.
