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.
