Drazice OKC 500 NTR / BP indirect heating boiler

newest series of enamelled floor heaters of indirect heating with a volume of 500 liters enamelled vessel and powerful one heat exchanger for heating the domestic hot water from an external source or combination of sources. When connecting two heat exchangers can receive the source of hot water for heating the total capacity up to 59 kW. The heater is equipped with hot water temperature controller (thermostat for controlling the three-way valve and circulation pump) with the power supply 230 V / 50 Hz.

In the lower part of the heater flange is viewing hatch for cleaning the inner surface of the tank and for installation if necessary, auxiliary electric heating TPK series elements. When applying a water heater system with solar panels, water heaters volume of 200 liters equipped with spigot 6/4 "heating element TJ, is placed above the solar heat exchanger

Application:. Heat water to hot water (heated by the coolant system heating / solar)

Description:..
Floor, vertical, circular
equipment protection IP44
polyurethane insulation without freon 65 mm
Lantseva connector for mounting an electrical heating element series R, which may be purchased as an option.
Energy «B» class.
tubular spiral heat exchanger area of ​​2.0 m² at model OKC 500 NTR / BP
The inner surface of the tank is covered by enamel without high nickel content, which in combination with a protective magnesium anode ensures durability of the heater.
Protective magnesium anode.
tank vodonagr evatelya including flange lid, made of the same material (steel), which prevents galvanic action and electrochemical corrosion. This solution is one of the main advantages heaters Drazice.
Service hatch allows to work inside the tank in order to eliminate scum, limescale and sludge, in the event of their occurrence.
Nozzle recirculation.
threaded hole .... 6/4 "for mounting additional electric heater TJ series, which is available as optional equipment
