3.2 Whole house applications
Whole house applications cover the typical home applications up to
a 2 or 3 bedroom house. See the sizing guide (Section 2.1) to
determine the best Bosch water heater model for your application.
An enhanced design including an Ariston mini tank in line to the hot
water source will reduce the wait time for hot water and improve
temperature stability.
3.2.1 Powerstream Pro whole house applications
The RP17PT and RP27PT must be hard wired directly to the breaker
