Emergency Power Consumption - Dražice OKC 100 NTR Operation And Installation Manual

Advantages of using indirect heater
−
Easy installation and connection to heating water supply,
−
very fast HSW heating,
−
enamelled steel tank ensures all hygienic requirements on the quality of HSW,
−
built-in Mg anode increases resistance to corrosion,
−
good quality polyurethane insulation ensures minimum thermal losses,
−
continuously adjustable temperature of HSW up to 74°C,
−
connection of multiple withdrawal points,
−
the type with two heat exchangers can use two heating water supplies, or double heat
transfer surface can be obtained if those are combined,
−
heater operation control light,
−
accurate check of HSW temperature,
−
possibility of connecting HSW circulation.

1.2.3 EMERGENCY POWER CONSUMPTION

If no heated water is taken from the tank, a small amount of heat leaks. This loss is
measured for a period of 24 hours at the temperature of 65°C in the heater, and at 20°C in
its ambient area. The resulting value is expressed in [kWh/24h] and indicates the amount of
power needed to maintain the set temperature. Data Sheet pursuant to Directive No - see
Table 1.
