Heat accumulator Pellaqua

The buffer cylinder balances out differences between energy generation and energy consumption. This extends the service life of a pellet boiler, with positive side effects:
The number of burner starts is lower, fuel consumption and costs are reduced and the environmental impact is lessened.

The Pellaqua system cylinder is one step ahead of standard buffer cylinders.
The space-saving multi-functional solution makes elaborate wall installations, troublesome cable routing and complex piping a thing of the past.

All pumps for heating circuit distribution can be mounted together with the controller on the buffer cylinder.

Not only does this simplify installation and assembly for the heating engineer, it also creates space and establishes order in the boiler room.

The Pellaqua is designed in such a way that the heating water is stratified by temperature level into the buffer cylinder.
This optimised stratification leads to best possible, efficient, cost-reducing heat utilisation.

The ideal cylinder size for combination with solar collectors can be calculated using the following rule of thumb:
1 m² collector area = 80 litres cylinder capacity.

For a detached house accommodating a family of four, with 12 m² of solar collectors (for central heating backup), this means: 12 m² x 80 l ~ 960 l cylinder capacity.

During development of the Pellaqua, the buffer cylinder, heating circuit system and controller were coordinated perfectly with one another. Consequently, the system achieves a higher efficiency.
