Can a constant-temperature water bath with a steam coil maintain a constant temperature? If there is a steam coil, isn’t it unnecessary to use an electric heating device?

There is a constant-temperature water bath; according to the customer’s technical requirements, a steam coil is used to heat 180 kg of water to 95°C within 20 minutes, after which an electric heating device is used to maintain this temperature. It seems that those in charge of automation believe that a steam coil can achieve a precision control of ±1°C within the range of 0–95°C. Question: Regarding the question raised by everyone, when designing a constant-temperature container, if there is already a steam coil, shouldn’t an electric heating device be used?

It is not necessary to use electric heating; a temperature control valve on the steam side is sufficient.
