In 1992, Thomas Pekonen started the company Pinnab Inneklimat which today is a well-respected company within energy efficient indoor climate solutions.
“I then made contact with one of the world’s most respected research
teams within indoor climate, Dan Nordbäck and his team at Uppsala University,” continues Thomas Pekonen. “Our knowledge and expertise in indoor climate has inevitably led to the kind of solutions that are now being installed in a villa in Sigtuna. Here we are combining displaced floor mounted ventilation with radiant heat from the ceiling. Loggia heating panels are an excellent product even for a project as small as a regular house.
The result is not only a highly energy efficient solution, it is above all a solution that provides an extraordinarily agreeable indoor climate!”
The ventilation system works using a conventional FTX system that recovers the heat from the room’s air, but otherwise works without heating.
The heat instead comes from the Loggia heating panels installed in the villa upstairs floor and the basement. Today’s thin radiators no longer deserve the name radiators as they function more as convectors. Heating panels, on the other hand, are radiators in the proper sense because they really radiate heat and create a completely ideal room climate with pleasant comfortable warmth and good air circulation.
With this system’s time constant (= the system’s ability to respond to changes in the room’s climate) it also means an energy-efficient system. Often, conventional radiators and under floor heating keep going long after the temperature has increased, while this system responds instantly and gives a pleasant radiant heat when it is really needed.”
