Energy efficiency and indoor climate comfort are among the key challenges of contemporary living. Upgrading existing buildings, hospitality facilities or holiday homes often means dealing with technical constraints, architectural limitations and high installation costs. It is precisely within this context that Pisolo, the new climate control system developed by Deltacalor, finds its place. Designed to provide both heating and cooling, Pisolo eliminates the need for invasive building works or pre-existing HVAC systems.
Compact in size yet technologically advanced, Pisolo integrates a self-contained heat pump within a single unit capable of generating both warm and cool air using only a standard electrical outlet and two openings on an external wall. The absence of an outdoor unit and its slim 16-centimetre profile allow the system to blend discreetly into interiors, preserving the building’s aesthetics while minimizing installation impact.
The project was conceived to simplify climate control in existing spaces, where the installation of a traditional system may prove either technically challenging or economically impractical. Thanks to its integrated heat pump technology, outdoor air becomes the energy source required to ensure indoor comfort, while specially designed grilles with retractable shutters guarantee visual continuity and protection from external elements.
Beyond its ease of installation, Pisolo encourages a broader reflection on the relationship between building services and architecture. The possibility of heating and cooling a space without invasive construction works, external units and with a noise level of just 35 decibels makes the system particularly attractive for renovation, refurbishment and energy retrofitting projects.
Designed to respond to different needs, Pisolo is available in three versions. Pisolo Comfort focuses on efficiency through Inverter technology and an A+ energy rating. Pisolo PureAir incorporates an electrostatic filter capable of improving indoor air quality by significantly reducing PM2.5 fine particulate matter. Pisolo Hybrid, meanwhile, combines the heat pump with an integrated radiator that can be connected to an existing hydraulic heating system, offering a solution that provides both heating and cooling within a single device.
Particularly noteworthy is the attention paid to sustainability and the enhancement of existing building stock. The possibility of installing the system in hotels, apartments, bed & breakfasts or holiday homes responds to the growing demand for flexible, low-impact solutions within the built environment. At the same time, the use of R32 refrigerant and compliance with the latest European energy-efficiency regulations demonstrate Deltacalor’s commitment to developing products that help reduce both energy consumption and environmental impact.
More than a simple air-conditioning unit, Pisolo interprets comfort as an integral part of contemporary living. It offers a technology that engages in dialogue with existing architecture, enhancing spaces without altering their identity.
