The calculations and concepts behind choosing a heater or a fan.
Calculating heat output
Kcal/h = V × Δt × K. Divide by 860 for the output in kW.
Calculating ventilation airflow
Volume × air changes per hour = airflow in m³/h.
Direct, indirect or infrared
Where the combustion gases go decides the choice.
Drying out after water damage
Close the space, add gentle heat and keep the air moving.
