Climate

Air- conditioner

All AC'c in the house can be connected to one system.

Heated floor

Water or electric underfloor heating — both will work only when necessary.

Radiators

You can make your own microclimate even in each separate room.

Ventilation

Fresh air is important. Local, central ventilation, or even windows that open themselves, will help you with this.

Humidity

Dehumidifier or humidifier - depends on the climate. But whatever it is — let it work without your intervention.

Air purifier

Unpleasant odors, small particles and allergens — it's much easier to breathe without all this.

Clothes dryer

Heated towel rail or the warm wall will work only when wet things are hanging on them.

Why you need this?

Comfort
The temperature no longer fluctuates around the desired value, but really supports it. This difference is difficult to explain, but it is easy to feel.
Economy
A temperature difference of even one degree can lead to overpayment for electricity and gas up to 10%.
Efficiency
Exceeding the level of carbon dioxide in an apartment can lead to fatigue, strong decrease in human performance and literal "stupefaction".
Ease of use
You need to set the desired temperature and humidity values in one place. Then everything works without your participation.
