Is it still hot after the water in the separator is pumped out?
Yes, but it will affect the temperature. When the water separator is running, it needs to use a lot of low-temperature water, so it can be recycled normally. However, after the radiator is connected, if the water supply is insufficient, it will easily affect its heating effect. If half of the rotary core valve on the water separator is closed, the temperature of the corresponding heating position will be reduced. Poor quality of water separator will affect indoor water supply, thus affecting heating temperature.
