Comparison Vitals EH-37 vs Grunhelm PTC-3000R

The maximum amount of air that an industrial heater can pass through itself in a certain time.

This parameter is associated with an increase in air temperature (see above): at constant power, higher performance usually corresponds to a smaller temperature difference. Accordingly, a more efficient industrial heater will heat the entire volume of the room faster, but the heating temperature will be lower. So, it is worth choosing according to this parameter, taking into account what is more important for you — a large temperature difference or a high heating rate.
