If you need a DHW tank for your boiler, the obvious choice for you is to use an indirectly heated tank. You can connect it to a stationary or wall-mounted boiler with a variety of energy sources.
Suitable for external heat sources
Indirectly heated wall-mounted storage tanks OKC, OKCV, OKH, NTR, SOL are manufactured in volumes from 120 l to 195 l. They are intended for connection to biomass boilers, stationary or wall-mounted condensing boilers with various energy sources for the preparation of domestic hot water in residential and non-residential premises.
Stationary tank ATTACK OKC NTR
High-quality indirectly heated hot water tank works with one exchanger and can be used with various heat sources. The tank has a special anti-corrosion layer, which prevents pitting corrosion. To prevent heat loss, high-quality Covestro insulation is used, which also ensures minimal operating costs. The tank is equipped with a DHW heating temperature control, a safety valve and a circulation outlet.
Ceramic heating element
With one exchanger
Heating options: electric energy, exchanger Anti-corrosion layer resistant to hard and chlorine water
Quality insulation for low heat loss and operating costs
Suitable for wood boilers
Stationary magazine ATTACK OKC NTRR/SOL
If you need a more complex tank that can also handle connection to solar panels, it is appropriate for you to reach for this indirectly heated tank, which has exchanger surfaces optimized for solar panels. It is equipped with two exchangers and a special anti-corrosion layer that is resistant to pitting corrosion. The NTRR/SOL tank achieves better water stratification thanks to its adjusted dimensions. You can use it as a main tank, but also as a preheater before the original DHW tank.
Ceramic heating element
With one exchanger
In the version with a 1 m2 exchanger, the tank is suitable for boilers for various fuels and for condensing boilers
Equipped with a circulation nozzle
Anti-corrosion layer resistant to hard and chlorine water
High-quality insulation for low heat loss and operating costs
Includes an electric heating element
Suitable for wood or gas boilers
Stationary magazine ATTACK OKC NTR/HV
The tank operating on the principle of indirect heating OKC NTR/HV has one exchanger. It is suitable for installation under wall-mounted boilers, to which the location of the inputs and outputs is also adapted. They are located in the upper lid, so their connection is simple and problem-free. The indirectly heated tank is equipped with an anti-corrosion layer, which protects it from the effects of hard and chlorinated water. With high-quality Covestro insulation, the tank ensures low heat losses and low operating costs.
