Hello everyone,
I have been living in my new house for 4 months.
Our house (16cm aerated concrete precast walls + insulation) has underfloor heating upstairs and downstairs as well as a heating system (air-to-water heat pump) from Vaillant.
In all rooms, I have individual controllers for the room temperature as well as a separate control unit from Vaillant at the location (utility room) of the heating system, where I can, among other things, set the general desired temperature and time-limited temperatures (e.g., reduce the desired temperature at night by 4 degrees).
Initially, I had set a temperature of about 21 degrees in many rooms. In the bedroom 19 degrees and in the bathroom 22 degrees. On the central control unit, I had set a desired temperature of 23 degrees.
Since it was almost always warmer than the room setting temperature in the rooms due to good insulation and the outside temperatures, the heating was almost never activated. Only in the utility room did heating seem to be continuous during the day. As a result, the temperature there was around 24-25 degrees. That was clearly too warm for me, as food is also stored there. Both the separate room controller (set to 18 degrees) and the central control unit of the system (with the central desired temperature of 23 degrees) in the utility room were set lower. Therefore, I spoke to the heating technician.
He explained the following to me: The central control unit is like the gas pedal of a car, and the individual room controllers are like hand brakes.
Therefore, I was always driving with the handbrake engaged (lower value in the individual room than on the central control unit in the utility room). As a result, the warm water of the underfloor heating accumulated in the utility room.
He advised me to set all controllers in the rooms to a higher temperature (e.g., 25 degrees) (i.e., release the handbrake) and slowly reduce the central desired temperature setting (i.e., gas) until this produces the desired effect. As a result, the air-to-water heat pump would run continuously because the temperatures in the individual rooms never correspond to the setting, and the utility room would no longer suffer from such increased heat. Also, it is good in a house with insulation and an air-to-water heat pump if it runs continuously.
Is this explanation with gas and handbrake correct?
