What is comfort? Common definitions talk of a state of wellbeing for a person, caused by external influences in his surroundings. Comfort is subjective to an extent. Physical condition and state of mind are just as important as the thermal environment which most people regard as comfortable. Thus experts have determined that a constant temperature in the air and surrounding walls of 22 degrees Celsius for a person wearing average clothing, with little air movement and with moderate physical activity is regarded as pleasant.
A person’s physical or mental productivity depends to a significant extent on "thermal comfort", as the experts term it. When people feel comfortable, their metabolism and energy conversion work as required by their level of physical activity; their cardiovascular system is comparatively unstressed, their power reserves are high, and they do not tire so quickly. Viewed in this light, comfort is not a luxury but a necessity with regard to performance and health. A comfortable workplace, for example, contributes to staff productivity and a company’s economic success.

It is no wonder, against the backdrop of these research results, that people also wish to achieve comfort in their private sphere as a feeling of wellbeing at home too enables people to recover from their everyday obligations, relax and gather new strength for the tasks ahead of them. Those who work from home will also ensure that their home-based workplace is designed to provide a comfortable environment and a pleasant indoor climate.

"Warmth," states Gero Frischmann, head of Sales Documentation and Information at BBT Thermotechnik GmbH, "is one of the significant contributors to basic comfort, with hot water also having a role to play." The comprehensive product portfolio of the BBT Thermotechnik GmbH brands addresses this factor, for flats and houses of any size and style.
"People are at the heart of all this," states Frischmann, with reference to human comfort. And this is provided by technology which, as he puts it, "fully" meets the user’s requirements: hot water as soon as the tap is turned on, and room temperatures as required by the particular situation. After all, who wants to run around in the cold until leaving the house in the morning or wait for ages until room temperatures reach a pleasant level on returning home. Today’s systems engineering and control technology enables a room temperature to be planned and specified far in advance. Don’t want to think that far ahead? There are still ways of ensuring that you always achieve a pleasant climate quickly. System control enables temperatures to be raised fast – when returning from holiday, for example – as the controller can quickly mobilise all its reserves once it has been requested to do so by the user pressing the appropriate button.

The unit which triggers this differentiated control action is generally in the living room and looks just like a remote control. The head of the energy control system allows the user to define the heating situation in his house in an easily comprehensible manner, for example using symbols or icons. Solar power systems can also be connected to the energy control system.

Those who heat or draw hot water on demand ensure that no energy is wasted. It is logical, therefore, that a modern heating system offers greater convenience while also saving energy at the same time. Replacing old heating systems is therefore helping to protect natural resources, and their lower power demand is contributing to a reduction in CO2 emissions.
The system compatibility of the components is crucial in all this. Customers, according to Frischmann, therefore want to obtain everything from a single source and want all the essential elements for a domestic comfort system to fit well together as "only coordinated components are capable of creating true comfort".
