PELLAQUA stratification cylinder

 
Pellaqua stratification cylinder

Increases the efficiency of the heating system

  • Increases the annual output of the heating system

  • Saves heating costs by improving fuel usage

  • Ensures a long pellet boiler service life

The stratification cylinder developed in-house by ÖkoFEN is the optimally coordinated interface between your pellet boiler and solar collectors.

 

In contrast to conventional stratification cylinders, the Pellaqua has an intelligent stratification pipe system. All hydraulic and control components are already integrated. Three available cylinder sizes of between 600 and 1000 litres enable selection based on individual requirements.


The versatile, powerful ÖkoFEN stratification cylinder is also delivered ready for connection. You can begin to heat immediately after an extremely short installation on site.

Why use an accumulator tank?

Why use an accumulator tank?

The accumulator tank is the storage heart of your heating system. It balances out differences between energy generation and energy consumption, which has the duel benefits of controlling costs and reducing wear and tear on your boiler.


The number of burner starts is kept to a minimum by storing the energy you have already generated, leading to less pellet consumption, lower stresses on the boiler and less impact on the environment.

Complete and versatile

Complete and versatile

The Pellaqua is far superior to conventional accumulator tanks. It accomplishes an number of functions as the interface between your solar system and pellet boiler.


All of the pumps for the heating distribution circuit are contained within the Pellaqua, as are all of the heat exchangers for solar energy input and domestic hot water from your boiler. It is fully integrated into the Pellematic control system and ready-wired for swift connection into your installation. It can even be retrofitted with a solar heat exchanger if you add solar collectors at a later date.

Clean boiler room solution

Clean boiler room solution

All of the components needed for heating circuit distribution are installed under the Pellaqua’s insulation hood, avoiding costly wall installations and complicated cable and pipe routing.


This self-contained solution, including all of the controls and control wiring ensures the boiler room remains clean, tidy and uncluttered.

Heat stratification system

Heat stratification system

The Pellaqua is designed in such a way that the heat from both the solar thermal system and the heating system enters into the accumulator tank via two ideally matched stratification pipes. 

 

This ensures the most effective stratification of the hot water and leads to more efficient and cost-effective use of the heat you have produced.

From a single source

From a single source

Great care was taken during the development of the Pellaqua accumulator tank that the heating circuit, distribution system and controller would work seamlessly together. Achieving this has enabled the creation of the most efficient product possible.

 

It’s a simple principal of production that is also reflected in the personal service we strive to provide to all OkoFEN customers, ensuring you have a single, competent contact for all of your questions and needs.

Correctly sized

Correctly sized

The ideal cylinder size for the combination of a pellet boiler with solar collectors can be calculated using the following rule of thumb: 1 m² collector surface area = 100 litres cylinder capacity.

 

For a detached house accommodating a family of four, which uses a solar thermal system with 10 m² of collectors for central heating backup, this means: 10 m² x 100 l = 1000 l cylinder capacity. The recommended cylinder would be the Pellaqua 1000.
