Important features that the operator has to consider in order to choose the ideal gas heater which best suits his requirements according to the room that has to be heated up.
- Dimensions of the area that has to be heated up[V].
- The ideal temperature [ΔT] that has to be reached.
- Room thermal insulation [K].
High thermal insulation: k = 1
Medium levels thermal insulation: k = 2
Low thermal insulation: k = 3
No thermal insulation: k = 4
Therefore, the heat requirements can be also calculated by using the following formula:
V x ΔT x K [kcal/h]
V = 4 mt width, 12 mt length, 3 mt height, room volume = 144 m³
ΔT = outdoor temperature -5ºC, room required temperature +18ºC, room temperature = 23ºC
K = 4 not-insulated room
The formula above mentioned brings to the following result: 144 x 23 x 4 = 13 248 kcal/h, which has to be compared with the data written on the machine label, which highlights this gas heater functionality being able to produce larger volumes of instant heat compared to that one needed.
