Underfloor heating is one of the most reliable heating systems, in which hot water at a temperature of 30-45oC circulates through a piping circuit that has been integrated into the floor of the room, turning the floor itself into a heating element.

The heat radiates from the floor to the heated space and from the lower layers to the higher without strong currents.

The boiler is the most important part of a heating system, since it heats the water thus transferring the heat through the water to the respective heating surface.

Oil boilers are divided into three main categories according to their construction material and their mode of operation. Specifically, these three categories are:
• Steel
• Cast iron
• Concentrates

Gas boilers are divided into LPG (liquid gas) which use a propane-butane mixture for combustion and natural gas boilers.

Electric boilers are an advantageous and smart solution for heating and hot water.
Through integrated electrical resistances, they heat the water which feeds the terminal elements of the heating.

They are the basic and most widespread type of terminal heating units.

The modern requirements for smart buildings, whether they are small installations, such as residences, or large ones, such as hotels, require the use of automation, suitable to achieve maximum comfort, ideal living conditions, speed and savings.

Circulators are electric water-cooled pumps which are used for the forced circulation of water in cooling/heating systems.
