1 TECHNICAL SPECIFICATION OF PRODUCT
1.1 FUNCTION DESCRIPTION
Indirect stationary heater OKC 250 (300, 400, 500, 750, 1000) NTR / HP is designed for water heating in
conjunction with a heat pump. Reheat can be carried out by the electric heater TJ 6 / 4".
1.2 DESIGN AND GENERAL HEATER DIMENSIONS
1.2.1 PRODUCT DESCRIPTION
The heater vessel is welded from a steel plate and as a whole is protected by enamel resistant to hot water.
Magnesium anode is added in the vessel as an additional protection against corrosion, which regulates the
electric potential of the inside of the vessel and thus reduces the effects of corrosion. Inside the vessel
there is a welded heat exchanger made of steel pipe with enamelled outer coating, and connections of hot
and cold water, circulation and thermostat tank.
The pipe heat exchanger is only intended for the heating circuit.
On the side of the heater there is a cleaning and inspection aperture ending with a flange of 110 mm
diameter, the pitch of eight M8 bolts is 150 mm. The heater is equipped with a G 1 ½ " aperture for
screwing an additional heater. This option is used, if the heater is connected into the system with a heat
pump, for water reheating at the top of the heater to the desired temperature. The tank is insulated by 50
or 60 mm of polyurethane foam not containing CFCs and the casing of the heater is made of plastic.
