Outwardly, the house in Dornava is elegant and modern, but inside, it surprises us with vibrant furnishings, picturesque ceilings, and exceptional comfort. Let's see what hides behind the nine doors of this home.

The owner of the house in the Ptuj field travels extensively around the world, both for business and with family, visiting many houses, hotels, and industrial buildings along the way. “I professionally deal with electrical and mechanical installations, so in every building, I immediately notice lights, switches, ventilation, heating systems, but above all, I am always impressed by beautiful interiors. And I have incorporated some of that into my home,” explains Roman Zemljarič.

His house spans 200 square meters. Before starting to plan the house with an architect, the owner knew precisely which part of the plot was the most peaceful and suitable for the bedroom and children’s rooms. Roman admits that everything in the house is designed as he initially envisioned, except for the roof. “Because we are relatively close to Ptuj and Ptuj Castle, a flat roof was not possible due to spatial planning in this area. So, we made a compromise – on the accessible roof, we installed a solar power plant in the form of a gable.”




Let’s take a closer look at the interior of the house. First, a small but functional entrance hall with a practical wardrobe welcomes us. There is no hallway in the house; instead, we immediately enter a vast living room, the heart of the home.


Nine doors lead from the central part to other rooms, with frames reaching to the ceiling. Striking doors in smoked oak color also dictated the choice of furniture: a prominent dark sideboard with golden details is ordered from Portugal, while other wooden furniture, such as the dining table, is crafted in a carpenter’s workshop, in line with the owner’s ideas.


An unusual cube is a prominent element in the living area. On one side, it serves as a decorative shelf that turns into a kitchen element around the corner, while on the other side of the wall, a circular family bathroom is hidden.



Roman paid a lot of attention to lighting. “The living room is large. In this space, only three light fixtures are visible. If I had kept the ceiling flat, we would have the impression of being in a factory. That’s why I opted for architectural lighting hidden behind a dropped ceiling. In addition, we treated the ceiling with a special technique, resulting in a solution that creates a pleasant atmosphere.” Similar lighting arrangements as in the living room are repeated in the kitchen, family bathroom, and bedroom.


The house is designed as a low-energy building and equipped with the most efficient heating and cooling system. Inside the building, wall and ceiling cooling, as well as underfloor heating, are installed. The boiler room, located separately from the main building, is equipped with KRONOTERM’s ETERA heat pump, a water-to-water system. “Due to the high groundwater level in Dornava, it turned out that the water-to-water heat pump was the most logical choice. I am extremely satisfied with its operation and wouldn’t exchange it for any other solution,” emphasizes the owner.


Dr. Dean Besednjak from KRONOTERM emphasizes that the ETERA heat pump is easy to install, use, and maintain. “It looks like a white cabinet, but it hides a very complex technical soul that allows us to achieve maximum efficiency and quiet operation. In designing this device, we made sure that all installations are hidden, so an actual visitor will not notice that it is a heat pump but rather a cabinet,” explains the expert.


Besednjak further explains the advantages of the chosen water-to-water heat pump. “We achieve maximum efficiency with it. In this case, from one kilowatt-hour of electrical energy, we produce eight and a half kilowatts of thermal energy. This means that, in terms of efficiency, it significantly surpasses all other types of heat pumps.”



An advantage of the water-to-water heat pump is that it can be used for heating in winter and cooling in summer, in addition to providing hot domestic water all the time. “With one device, we cover multiple functions, which is efficient and economical,” explains Dr. Besednjak.

Roman Zemljarič also assures that the use and management of the heat pump are straightforward. “In each room, we can set our own temperature. The bedroom is cooler, and the bathroom is, of course, warmer. All these spaces have temperatures ranging from 22 to 23 degrees throughout the year. All we have to do is take the phone, open the KRONOTERM app, and switch to cooling or heating as needed.”



By the window in the living room, we noticed special shelves made by the owner from curtain rods. They conceal switches and USB outlets. The home is also equipped with a TV stand with excellent audio. The family enjoys watching good movies there and often ensures that good music resonates inside. However, the sound of nature also has its charm. Therefore, they often gather on the terrace or under the canopy at the end of the garden.


Although the garden is still young, the trees thrive due to the high groundwater, located just three meters below the surface. This precious water in the soil brings many benefits, and one of them is not just the lush growth of plants.

One of the key advantages is the added value of the property due to the implemented water borehole, serving as a source for the heat pump. With a constant source from the ground, this system not only improves the efficiency of heating and cooling at home but also represents a long-term investment. “The borehole will benefit multiple generations. When the life span of the heat pump ends, it can be easily upgraded with the latest technology,” explains the expert from KRONOTERM. This ensures that future owners and users of the property will enjoy lower maintenance and operating costs of the heat pump.

Both the garden and the water borehole are symbols of a sustainable and environmentally conscious way of life, bringing benefits to both current and future generations, carefully balanced with nature and technology.
