DOMESTIC HOT WATER SYSTEM DESIGN

• Copper tubing or plastic Hep
for the domestic hot water system. Unnecessary
pressure losses should be avoided.
• The boiler may operate with a minimum supply
pressure of 0,3 bar but under a reduced flow rate.
Optimum performance will be obtained from a
supply pressure of 1 bar.

the boiler to a maximum of 12 l/min.
