How do ceiling heating and cooling work?

The current building regulations, with increasingly strict parameters regarding the insulation values of the envelope in new and renovated buildings, mean that today cooling a building is a more "demanding" operation compared to heating it.

Radiant floor and ceiling systems are able to meet the energy needs for heating buildings; as for cooling, it is probably the ceiling system that can cover a greater number of cases.

In any case, the HVAC engineer will check, case by case, which is the most suitable solution to meet the needs of the home.

A ceiling heating system follows the model of a floor system, always working through radiant panels that distribute heat evenly by radiation and only secondarily by convection. 

With heat exchange by radiation, heat passes from hot surfaces to cold ones, from the body with a higher temperature to the one with a lower temperature: this is the type of heating that imitates nature, because it is the same as what the sun does with the Earth.

 The fact that heat is also partially transmitted by convection is the reason why the radiant ceiling is less efficient in heating and more efficient in cooling (hot air rises while cold air falls), compared to the same system installed on the floor.
