ALONE CONFIGURATION
The setup of the boiler system depends on the type of boiler selected:
- EWD tanks have a patented mixing device inside, which mixes cold fresh water with hot water from the
tank to provide feed water with the right temperature to the boiler. The setup is shown in 8.1.3, figure 1
- When other tanks are used, it is necessary to mix the cold fresh water with warm water from the tank,
outside of the tank. The mixed water will serve as input to the boiler.
The setup is shown in §8.1.4.
