|Q:||Which is better underfloor heating or radiators?|
We get asked a lot whether an underfloor heating system is better than a central heating system with radiators. To answer this its worth understanding how each system works:
Conventional heating or central heating works on the principle of convection, allowing the heat to circulate the room in an ever-flowing current of air ie cold air sinking and hot air rising. While the hot air is rising it loses momentum due to heat loss- the energy is transferred- the air cools and sinks back down again only to be warmed again by the radiator and start the cycle again. A radiator heats the air near to the radiator so in order to heat a larger area it needs to work harder at higher temperatures. The name 'radiator' is misleading as they radiate very little. A room that is heated in this way will have higher air temperature up at the ceiling. Cold feet and a hot head!
Underfloor heating radiates heat from the floor up. Heat is lost once you have felt its benefit. Underfloor heating operates at lower temperatures and has the added benefit of being concealed so is also space saving. Underfloor heating creates a warm floor making it popular in bathrooms - a real luxury on a cold winters morning. Warm feet and a cool head.
