Each person who receives or draws fuel or energy under the contract with the power engineering company.
It allows for commencement of heat supply to the real estate.
The set of devices or systems used for heat generation (heat sources are components of heating systems n the form of heat and power plant (in addition to heat, they generate electric power) or heat plants, whereas when they are directly located in the facility, they have the nature of local heat source).
The industrial plant generating electric power and heat in the form of high temperature medium (most often water) for heating networks in one technological process in the combined manner (cogeneration).

The set of prices and fee rates as well as terms of their application prepared by the supplier of system heat and implemented as the effective for Recipients specified therein under the Energy law act.
Heat exchanger of water-air or vapour-air type; component of the facility (rooms) heating system.
An instrument used to adjust the temperature of heating devices (heaters)
The function of relations between external temperature, delivery temperature and setpoint of room temperature. A standard heating curve is 90/70°C. It means that at the external temperature of -16°C, the temperature inside the room shall be at the level of +20 -21 °C.
The interconnected devices or systems (sometimes called heat-pipes) used for transmission and distribution of heat in the form of hot water or vapour from heat sources to heat cenres.
The industrial plant the main task of which is production of medium (most often water) with high temperature and its transmission to the heating system or for the purposes of industry.
The period in which the weather conditions result in the necessity of continuous heat supply in order to heat the buildings. However, this word is removed from dictionaries as heat from the municipal network is now available all year round.
A basic unit of energy. A billion of joules is a gigajoule (GJ), a million of joules is megajoule (MJ).

It is an intelligent solution of GPEC Group based on the weather automation built-in in the centre - the option of automatic activation and deactivation of supplied heat depending on the existence of specified external temperature, called threshold temperature. With the sensor placed outside the building, the automatics itself monitors the weather conditions and - most importantly - automatically activates heat exactly when it is needed. 12 and 14 degrees Celsius are recommended threshold temperatures for activation of heat supply and/or stop.
