[Equest-users] Is it possible to disable PSZ heat pump hot gas reheat dehumidification and enable PSZ electric coil dehumidification?

[Sharad Kumar]

Hi Kathryn,

As per me there is no system such as heat pump hot gas reheat
de-humidification system.
The de-humidification system mainly consists of a cooling system (cooling
coil) which can form condensate to reduce the moisture content of air and
segregate it from air.
In your case the gas reheat de-humidification can be considered as
electrical coil humidifier which can bring good enough savings.
In the electric coil humidification the heat source for latent heat of
vaporization is electricity or in case of furnace, gas or fuel is the
source of heat for water to be vaporized and so on.

Thanks,
