 # :volcano: Heating system
 
-Since beginning of winter 2021, Kanthaus is powered by an air heatpump heating system which is partly installed in the garden next to K20 garden door (actual heater), in K20 "water storage room" (some connections, valves, filters, meters) and the rest of the house (pipes, radiators).
+Since beginning of Winter 2021, Kanthaus is powered by an air heatpump heating system. It is installed in the garden next to K20 garden door (actual heater), in K20-B water room (some connections, valves, filters, meters) and the rest of the house (pipes, radiators).
 
 ## User guidelines
 
 What is special about a heatpump heating system is that to be efficient, the heating system's water temperature has to be as cold as possible, while still keeping the house warm. That means:
 
-* You can not heat up a room quickly - turn on the radiator at least 4 hours before you want to notice some warmth, expect a room to becomme "warm" only 2 days after turning on the radiator
-* The maximum reachable temperature in a room is given by the settings of the central heating systems, normally should be around 19.5 °C in Kanthaus
-* To keep the efficiency of the system high, we actively decided that "badly heatable rooms" (e.g. with too small radiators for the specific room) stay colder. An incomplete list (generally notice badly heatable rooms by looking at the 6 surfaces of the room: The more cold rooms are on the other sides, the worse heating works)
+* <div style="color:red;">You can not heat up a room quickly</div> - expect a room to become really warm only 2 days after turning on the radiator
+* Much of the temperature control is set centrally. Thus, turning the knobs on the radiators doesn't do much more than switching on or off.
+* <div style="color:red;">The maximum reachable temperature is usually around 19.5 °C in Kanthaus.</div> 
+* To keep the efficiency of the system high, we actively decided that "badly heatable rooms" (e.g. with too small radiators for the specific room) stay colder. Here's an incomplete list of those rooms:
     * The Private (~13 degrees)
     * Freeshop Lounge (~13 degrees)
     * Cloud room (~14 degrees)
     * Hipster room (~13 degrees)
     * Sleep kitchen
     * Dragon Room
+    * Ex Food Storage
 
-Additionally, a heatpump works very differently from a gas heating system and likes to run continously, as well as needs a minimum water flow through the radiators to work at all. This means at least 6 radiators need to be turned on all the time.

 The heating system is normally running all day, heating power is slightly reduced during nighttime. It is normal and wanted that the heatpump outside is working all the time.
 
 When it is warm outside (> 5 degrees), we might turn off the heatpump during nighttime.
 
+### Hot water
+
+The heatpump is also responsible for hot water being available in the Main Bathroom, the Main Kitchen and the Snack Kitchen. We have a hot water tank in K20-B water room for that purpose. When full and freshly heated, it holds 200 liters of 50°C water.
+
+<div style="color:red;">Heating water for showering and water for radiators is not possible simultaneously!</div>
+
+Usually the heatpump switches to water mode once a day at some point when it's sunny. If the hot water tank in K20-B water room is empty, however, it immediately starts heating it up again.

 A heating controller program is running on `kanthaus-server`. It maintains comfortable temperatures in the house while minimizing energy usage. It does this by reading room temperature sensor data from InfluxDB and adjusting the heating water target temperature via Heishamon. Also, it can switch the heating on or off based on temperature thresholds.
