The amount of heat produced by a dehumidifier varies depending on its capacity, efficiency, and operating conditions. Generally, a dehumidifier produces a minimal amount of heat, typically around 1-2 watts per liter of water removed. This heat gain is usually offset by the cooling effect of the dehumidified air, making the overall impact on the indoor temperature negligible. However, in extremely humid environments or during prolonged operation, the heat gain may become more noticeable.
