explained simply.

All about heating. From A to Z.

When it comes to heating, there are a few technical terms that need to be explained. You can find everything you need to know here. In alphabetical order.

Flow temperature

The temperature of the Heating circuit  water flowing to a radiator. As a rule, the flow temperature in radiator heating systems is up to 70 °C (up to 40 °C in underfloor heating systems). The temperatures are only that high, however, when outside temperatures are low. If the outside temperature increases, then the flow temperatures decreases.
