HydroConnect 180+75 combines a 75-litre buffer tank and a 180-litre DHW tank in a single compact unit. It features various outlets at the top for connection to the DHW system, the heating and cooling system, and the heat pump or chiller (air-source, ground-source, etc.), making installation quick and easy.
HydroConnect incorporates different Plug & Play outputs located on the top for quick and easy installation.
This combined buffer tank is specifically designed to be combined with a heat pump (air source heat pump, geothermal heat pump, etc.).
Made from high quality materials, it guarantees a long service life, maintaining safety standards at all times.
A single unit for storing water for heating, cooling and domestic hot water, eliminating the need to install multiple tanks or systems.
Unlike a conventional inertia tank, HydroConnect can store hot water and water used for heating.
Thanks to the inclusion of various outlets located at the top of the unit, it can be easily connected to the DHW system, the heating/cooling system and the heat pump or chiller (air-source, ground-source, etc.), making installation much simpler and quicker.
Discover the differences between a conventional buffer tank and Efitherma’s HydroConnect:
HydroConnect is designed to be quick and easy to install, requiring fewer connections than a traditional system with separate tanks. It also operates with an efficiency oriented approach, reducing energy consumption and the costs associated with the production of DHW and Climate
The differences with respect to a conventional inertia tank are many, some of the most notable are: it’s dual functionality and multiple applications.
It’s stainless steel tanks, together with the titanium electronic anode against impressed current corrosion, ensure greater durability and efficiency in its operation. It also includes protection against legionella bacteria to ensure the healthiness of the stored water.
