Since the beginning of mankind, the process of heat generation has been the focus of attention. After all, warmth not only ensures survival, but also provides a sense of well-being. Nowadays, heat is only a click away, but that was not always the case.
Vienna, September 2018 - If an early ancestor was born today, he would be surprised at the development of heating solutions. It all began as a flame and became an open campfire, which served as a source of warmth for mankind until the Middle Ages. However, it only warmed if it was burning and the heat quickly escaped in all directions. Therefore, stones were used as heat accumulators. They lay in the fire and took the heat. In the 14th century in Japan, the "Kotatsu" – a hole filled with embers and stones, covered by a blanket – was created. This was mostly under the dining table, where family members could gather and warm themselves. Even today, electrically powered “Kotatsu” are still present in Japan.
With the Romans, underfloor central heating arrived. It was mainly used in public baths. Air was heated in a central kiln and routed into gaps below the floor. The floor slabs got warm. Energy efficiency was low and fuel consumption high. Energy efficiency was therefore one of the driving forces behind the development of heating technology – from brick fireplaces, iron and tiled stoves, central heating in the 18th century, to oil and gas central heating in the 20th century.
Modern heat pump: the epitome of well-being.
Nowadays heat pumps are the ideal choice for staying warm and comfortable at home. They are not only economical in the long-term but also have a positive effect on the environment. Thanks to the use of renewable energies from air, ground or water together with utilization of sun energy through solar and photovoltaic panels, heating is more sustainable than ever before. Daikin´s Altherma 3 is quick and easy to install, providing homeowners with the highest energy rated comfort – no matter how cold it may be outside, thanks to Daikin´s pedigree trademark in frost protection down to -25°C. Rated A+++* , the heat pump is equally suitable for new and retrofit installations, as well as for connecting to underfloor heating systems and radiators. With an integrated domestic hot water tank, continuously available hot water can be used with minimal electrical input. Settings can be controlled remotely from anywhere via the Daikin Online Controller smartphone app or an online controller – for consistent room temperatures at any time. It has taken a long way in history, but now heat pumps are one of the most energy-friendly heating systems on the market.
