Choose the indoor arrangement for your system
Your heat pump, hot water requirements and available space all influence the indoor installation. Explore the options, then confirm the correct combination for your selected equipment.
HYDRO C2
HYDRO S2
Wall-Mounted Hydraulic Unit
A compact wall-mounted option for installations where separate hot water storage and a flexible equipment layout are preferred.
HYDRO B
Domestic Hot Water Module
A dedicated hot water module designed for integration with compatible ETERA geothermal heat pump installations.
A complete system approach
Give the indoor installation proper consideration
Choosing a heat pump also means planning the equipment inside the building. Hot water storage, hydraulic connections, controls and maintenance access all need to fit the proposed installation.
Kronoterm’s indoor units provide coordinated options for different system arrangements. Some combine hydraulic components and hot water storage, while others allow equipment to be positioned separately.
KronoHP helps installers and project teams explore the available combinations, with attention to compatibility, practical space requirements and the way the building will be used.

Layout and installation
Find the arrangement that fits the building
A combined floor-standing unit can keep equipment together, while a wall-mounted unit allows a different approach to positioning and storage. Look beyond the cabinet dimensions. Delivery routes, connection positions, service clearances and access to surrounding equipment all need consideration before the installation layout is agreed.
Discuss Installation Requirements
Hot water planning
Choose storage around everyday demand
Consider hot water requirements alongside the hydraulic arrangement. Household size, bathing routines and periods of concentrated use can influence the storage and recovery capacity needed. Compare the options within the proposed heat pump system, including integrated storage or a separately selected cylinder. Stored cylinder volume and usable hot water at the tap are different measures, so assess each specification on the same basis.
