Flow temperature

Temperature of the heating water which flows to the radiator. As a rule, the flow temperature in the case of radiator heating systems is 70 degrees Celsius (ca. 40 degrees in the case of floor heating systems). The temperatures are only that high, however, when the outside temperatures are low. If the outside temperature increases, the flow temperatures are less.

Fuels

Heating oil, natural gas, liquefied gas, and biogas are used as fuels and are essentially hydrocarbon chains. Their energy content is made usable by burning with air.
