A buffer cylinder ensures maximum efficiency from your pellet heating system
The heat centre
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.
Complete and versatile
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.
Clean boiler room solution
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.
Heat stratification system
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.
