The renovation of this 1956 apartment, located in a quiet part of Ljubljana, was more than just a visual upgrade – the owners wanted to create a modern, comfortable, and energy-efficient home for a student. Before the renovation, the apartment was in poor condition, with outdated installations, an inefficient layout, and an obsolete heating system. Additional constraints came from the building’s energy renovation, which prohibited the installation of outdoor units on the facade.
The existing electric boiler and radiators were inefficient and unsuitable for long-term use. The owners needed a solution with low operating costs, minimal construction work, and no visible external components. They also sought independence from district heating systems, allowing them full control over the start of the heating season.
The owners wanted a system that was quiet, efficient, and compatible with the building’s facade regulations. Since external units were not allowed, the ideal choice was the VERSI-I indoor heat pump – a system specially designed for indoor installation in houses and apartments.
It allows discreet installation and performs exceptionally well in tight spaces. In this case, the unit was placed in the basement directly beneath the apartment, which enabled optimal pipe routing with no impact on living space.
The VERSI-I is an air-to-water heat pump that uses discreet air vents instead of an outdoor unit, blending seamlessly into the building’s structure. It’s perfectly suited for apartment renovations where exterior units are not permitted.
Key advantages of the VERSI-I heat pump:
In addition to heating, the apartment needed an effective cooling and dehumidification solution. With enough space for underfloor heating, the owners ensured optimal comfort during winter. For summer, they added low-temperature fan coil units for active cooling and improved air circulation.
Thanks to a well-thought-out system choice, the apartment now provides quiet, automatic, and energy-efficient heating, with no visible external parts and significantly reduced heating costs.
