In order to raise the temperature of air with volume A [m³] and temperature B [°C] to C [°C] in D [hours], a Power of G [W] is required.

G [W] Power is required to raise the temperature of air with mass A [kg] and temperature B [°C] to C [°C] in D [hours].

In order to raise the temperature of water with mass A [kg] and temperature B [° C] to C [° C] in D [hours], a Power of E [W] is required, of which F% is the heat dissipation loss.

The heat loss depends on the heating conditions, the results should be used for reference purposes only.

Conditions for simple calculation

• The room temperature remains constant before heating, and the effects of wind are neglected.

• The container is a metal cubic one with its top exposed to air.

• The container is covered with insulation material.

• The thickness of the insulation material is 50mm.
