3. Determine power required for the cascade configuration
The first step in the installation procedure for the cascade configuration is to determine the total power required
for the cascade configuration. This power is calculated based on the size of the room(s) to be heated and other
relevant variables. If the required power in kW is known, consult Table 3.1 (below) in order to determine which
combination of boilers can be applied to achieve the required power.
