The Remeha Tzerra Ace-Matic is a boiler with guaranteed high and sustainable efficiency. This revolutionary boiler is equipped with an electronic, self-adjusting gas/air system. This ensures optimal settings and guarantees a high and lasting efficiency. Furthermore, the Tzerra Ace-Matic is future-ready.
Sustainable High Efficiency
The Tzerra Ace-Matic adjusts automatically. Not only at installation by the installer but also afterwards. The device continuously checks whether the settings are still optimal. If not, it automatically adjusts itself. This ensures that the settings are always correct.
Future-Ready
Thanks to the deep modulation of 1:8, the device is ideally suited for connection with a hybrid heat pump. Additionally, this boiler is compatible with natural gas mixed with up to 20% hydrogen. With the built-in solar boiler control as standard, the Tzerra Ace-Matic can easily be connected to a solar boiler or other sustainable solutions.
Advantages of the Tzerra Ace-Matic
