Standard accumulation tank AK and AS

ATTACK AK is a basic type of storage tank that accumulates excess energy from the heating source and then uses it later according to your needs. The AK tank is used only for the accumulation of heating water. The ATTACK AS storage tank model is equipped with one exchanger compared to the basic AK tank which can be easily connected to the solar system.

Where to buy

Standard accumulation tank AK and AS

We produce both types of AK and AS accumulation tanks with a wide choice of volume from 204 to 4940 liters. The accumulation tank is welded by a robotic welding machine which extends its service life, increases the performance and efficiency of the boiler. With full power and optimal efficiency you use less fuel and make heating greener. Another advantage is the minimum amount of tar and acids during combustion and consequently the high lifetime of the boiler and chimney.

Accumulation tank AK

This type is inteded for normal water heating.

Accumulation tank ATTACK AK

Accumulation tank AS

This type of accumulation tank is also suitable for heating water. It also allows connection to a solar panel or heat pump.

Standard accumulation tank and way of heating

The accumulation tank can be combined with various heating devices (storage electricity, solar devices or heat pumps) and also with radiators and underfloor heating.

Connection of accumulation tank in heating system

Thermal insulation

Each standard ATTACK AK and AS accumulation tank is also supplied with a soft removable insulating layer to better keep your storage tank warm. Insulation with a thickness of 100 mm of polyester fibers with imitation leather cover is installed on tank.

More effecitve combustion with biomass boilers

For protecting boilers DPX, DPX Combi Pellet, SLX, SLX Combi Pellet, Pellet30 Automatic Plus against damage and ensuring its long life-time we recommend to install the accumulation tank in combination with the mixing device Oventrop. For regular service it is very important to buy the boiler in the country you live in.
