**) Water flow rate is specified at heating
water temperature of 85 °C and the
temperature gradient of domestic hot
water of 35 °C (hot water input
temperature10 °C, hot water output
temperature
45 °C). As far as a boiler with the power
other than 26.5 kW is used for the
heater, then water flow rate is being
changed at equal above mentioned
input conditions as follows:
0

Characteristics of OV 100 L water heater
The specified times of water heating and flow rates are only valid in case that a Grundfos pump is connected into the system and its rmp switch
is in the position 3 (corresponds to the flow rate of 650 l/hour). As far as the pump is operated with lower rpm value (i.e. with lower supply rate),
the heating time of domestic hot water will be longer.
***) Important warning!
Set the heater thermostat at the maximum temperature of 60 °C (remark: Regulations in Czech Republic do not allow to distribute water at
temperature higher than
60 °C).
Once a week, set the heater thermostat at the temperature of 65°C to avoid the creation of legionella (bacillary bacteria originating in water.
They die between 60 and 65 °C temperature within several minutes and at 70 °C temperature they die within several seconds.).
7.2 Heater construction
To the VIADRUS GARDE G42 ECO boiler, you can also order VIADRUS OV 100 L separate stack heater for a preferential domestic hot water
preparation. The reservoir is thermally insulated with polyurethane and its internal surface is coated by double enameled layer which
guarantees a long service life. The operation and installation manual is enclosed to the heater.
The boiler standard electric connection is adjusted to Honeywell V 4044 F three-way valve connection ensuring the domestic hot water
preferential heating. The thermostat is a part of the heater.
