3. Appliance description
This pressure appliance heats domestic hot water electrically. The
appliance supplies one or more draw-off points.
In dual circuit operation, the appliance automatically heats up the
water content at any temperature settings when economy tariffs
apply (times stipulated by your power supply utility).
In addition, you can start rapid heating during peak tariff periods
when there is a higher DHW demand.
The internal steel cylinder is coated in special directly applied
"anticor
®
" enamel and equipped with a protective anode. The
anode protects the internal cylinder from corrosion.
Frost protection
During the economy tariff period, the appliance is also protected
against frost on the temperature setting "cold", as long as the
power supply is guaranteed. The appliance switches on in good
time and heats the water. The water supply line and the safety
assembly are not protected against frost by the appliance.
