Read this information in conjunction with Bosch Continuous Flow Gas Heaters Installation & User Handbook, and pump manufacturers operating instructions handbook. • The Accumulator design has exceptional thermal insulation to meet Australian Standard AS 1056, and the gas units have no heat loss when burners are off. As a result, this system is highly efficient with almost no "standing or waste" heat losses and of course absolute minimum heat wastage in storage to meet peak use.
PAGE 3
The "Primary Circulation" Circuit - causes water to flow through the gas heating process. The Primary Circulation Pump sources its water from the Accumulator cylinder or the mains supply or both. (This will depend on the flow rate through the mains pressure circuit). Because heated water is always discharged to the Accumulator the delivered temperature is very stable. Diagram 2 shows the Mains Pressure + Primary circuits.

COMBO System Capability The following chart will assist in the selection of the COMBO System that meets with your specific requirements. Even if you have specified a basic COMBO System with a single Bosch Continuous Flow Water Heater and the Everlast Accumulator and then your hot water delivery requirements increase; or if the hot water demand is not immediately known; this is a System where, if required, a further Bosch Continuous Flow Water Heater may be added.
