Where the building and system design permit, photovoltaic electricity can power the heat pump and the building structure can provide thermal storage.
Explore HYPOCAUSTEN: an innovative approach to heating from below, designed to make use of the space beneath an existing floor where the building structure allows.


Where the building and system design permit, photovoltaic electricity can power the heat pump and the building structure can provide thermal storage.

The concept is designed to use accessible space below an existing floor, avoiding floor removal where the property is suitable.
For suitable properties, HYPOCAUSTEN aims to reduce the disruption associated with conventional floor replacement.
The existing marble or tile may remain in place when access and construction conditions permit.
A retrofit approach designed to limit the scope of building work; timing depends on the property.
Avoiding floor removal can mean less dust, rubble and disruption than a conventional rebuild.
A heat-pump system can be assessed alongside your solar PV installation to improve overall energy use.
Because the existing floor covering can remain in place where the building permits, you may avoid related changes to doors, sockets, windows, thresholds and room height.
Separate areas can be controlled and monitored independently, subject to the final system design.
Integration with Home Assistant, Control4 or KNX can be assessed for the selected controls and equipment.
The building structure may store heat produced by a heat pump during sunny daytime hours for later use. Actual performance depends on the property and system design.
Enjoy comfortable floor warmth and the possibility of walking barefoot in winter. Health effects are not guaranteed; suitability and surface temperatures need technical assessment.
HYPOCAUSTEN has been developed in Marbella since 2018. A demonstration installation is available to view in Marbella by prior arrangement.

Energy-renovation funding may be available for qualifying projects under applicable programmes (often described as “renovación energética”). Eligibility must be confirmed with the relevant programme before budgeting.
The floor and building structure retain stored heat during a power cut and cool gradually. The heat pump does not need to run for stored heat to remain available.
HYPOCAUSTEN is inspired by the Roman hypocaust principle. The proposed retrofit uses the available space beneath the existing floor to transfer heat upward. Every building is different, so access, insulation, floor construction and heat demand must be checked first.
Illustrative concept only. The actual design and performance depend on the building and engineering assessment.
If your villa already has photovoltaic panels, a technical assessment can consider how a heat pump and your solar generation could work together. Actual savings depend on the building, system sizing, weather and energy-use patterns.
We review the existing floor, available cavity, access, insulation and heating requirements before recommending a solution.

Integration with Home Assistant and other automation systems

A security-shutter concept combining an unobtrusive roller-box camera, integrated lighting, tamper detection and smart ventilation. The design includes a concealed anti-lift mechanism and an inflatable sealing profile at the shutter slot.

These are product concepts; the final mechanical design, safety logic and emergency operation require engineering validation.
