What is the ideal temperature for underfloor heating?

Electric underfloor heating systems can reach higher temperatures than hydronic (wet) systems but for both types of systems, a thermostat setting of between 21°C and 25°C is usually ideal. To achieve these temperatures, the actual heat output from the underfloor heating system will be approximately twice that number.

Does underfloor heating warm the whole room?
