The high water contents vertical body boiler has two returns (high temperature and low temperature) to ensure the best operation in
condensation.
The high temperature water stratifies in the upper part of the body while the cold water accumulates in the lower part, where
condensation takes place. The boiler electronic board, with a user-friendly interface, allows to optimize the combustion, to manage a
possible remote cylinder for the production of DHW, and to manage the flow temperature in climatic mode.
The built-in electric board can be expanded by means of the RIELLOtech controls range both for cascade applications (up to 16 boilers)
and for the management of multiple systems, both high and low temperature ones.
All models are provided with an outdoor probe as standard.
The whole range is suitable for operation by means both of natural gas and LPG (the model TAU Unit 110 needs a specific LPG conversion
kit in addition).
- High quality and accuracy of the finishing
- Possibility to install directly in the boiler the hydraulics of an additional mix/direct zone by means of specific kits
(only model Tau Unit 35)
- Ease of maintenance thanks to the complete access to the internal components
- Reduced dimensions
