3 Domestic Water Heating Applications

Potable water

Potable water is water that is suitable for drinking. Bosch Water Heating appliances are approved to heat potable water only. Heating any other liquid other than potable water will void the manufactures warranty covering the appliance.

Introduction

This chapter covers the various application techniques Bosch Water Heating recommends. The schematics are to be used by professional contractors in designing a domestic water heating system. The applications covered range from single sink point-of-use applications to multi-appliance central domestic recirculation applications.

3.1 Point-of-use applications

Point-of-use applications cover the small applications that a large water heater would be inefficient for. Installing a smaller heater at a point-of-use puts the heater near the hot water demand and reduces the wait for hot water. Common applications for these appliances include homes, offices, warehouses, service stations, stores, conces- sion stands, and summer camps.
