When designing the heating system, does the number of pumps in the boiler room need to correspond to the number of boilers?
Not necessarily; generally, the load and number of feed water pumps are determined based on the boiler load. However, backup feed water pumps must be available, and they should be switched in periodically to ensure a steady water supply to the boiler.
Generally, no – pipelines are also not allowed, but a backup is necessary
Generally, the load and number of feed water pumps are determined based on the boiler load, but spare feed water pumps must be available and switched in periodically to ensure a steady water supply to the boiler.
There are usually 2 units, and the load capacity must be sufficient. The two units can be switched regularly, or they can be used as a backup in case of failures that require repair or replacement
No correspondence is required; at least 2 circulation water pumps are needed, with one serving as a spare
