Hello everyone,
We are currently planning our home’s technical systems. We will be installing an air-to-water heat pump, and my husband saw these Nest thermostats at his brother-in-law’s place and now absolutely wants them. Setting aside that these devices are quite expensive… how much do typical thermostats usually cost? Of course, there are probably all kinds of price ranges, but I mean the standard white or gray control units. Does anyone have experience with Nest? Do they just look good, or are these thermostats also effective? Can you tell the heating specialist, “Hey, skip your usual thermostats and install these ones instead?”
Thanks in advance for your help.

Let’s leave your personal issues aside. I have been dealing with this topic for quite some time and have not backed down at all. You are not providing any information here, only polemics. Your assumptions about my interpretation are wrong, and it seems you are not familiar with weather-compensated control, otherwise you wouldn’t say that now.
By the way, different heating demands are also controlled by the pipe layout (spacing), not just fundamentally through valves and ERR.

Sebastian7920 Oct 2015 15:54The polemics and personal "attacks" came from you, my friend. Mycraft and I have explained quite a bit, but nothing has come from you so far—only your religious beliefs.
Not a single fact has come from you. Everyone can form their own opinion.
The way you present astonishing information bit by bit already suggests that you are dealing with the topic for the first time—which is not necessarily a bad thing.

Bautraum201520 Oct 2015 15:57That's enough now! What is this supposed to mean?
I've completely lost track. Can someone briefly explain again why an ERR for an air-to-water heat pump with a room-air-independent chimney is nonsense? And what could happen in the worst case if one operates it like that? Your jabs have caused me to lose the information.

I agree with Bautraum2015 and ask you to settle your disputes. While this is not meant to be a conflict-free forum, the tone of your conversation is gradually drifting into mutual accusations, which is not the purpose of a public exchange.
It’s one thing to have different opinions. But if you cannot even find the smallest common ground in your discussions, you should stop; at least resolve it outside the public area.
Best regards, Bauexperte

I’m completely lost. Can someone briefly summarize again why an ERR for an air-to-water heat pump with a room-air-independent chimney is nonsense? And what could happen in the worst case if you operate it anyway? Your teasing made me lose the information.As mentioned earlier, with ERR the underfloor heating fluctuates within several degrees Celsius (several degrees Fahrenheit), whereas without ERR it only fluctuates within about 1°C (2°F). There is no constant heating up and cooling down. The desired temperature is set once and maintained. Just look at the two curves I posted...
If you go on vacation, you need to set this on the heating system, which then switches to frost protection mode or setback mode depending on the setting for that period.
The chimney causes disturbances and essentially cannot be regulated, but due to the self-regulating effect, the room with the chimney does not absorb any more heat when it is on; the room will overheat. However, if there is no ERR, nothing further happens except maybe minimal gains and removal of excess heat. With ERR, the room is disconnected and isolated from the system until the air temperature in that room falls below the set value minus the hysteresis—in other words, until the floor cools down. Then the ERR switches again and reheats the room to the target temperature.
Without ERR, the room also overheats, but to a lesser degree, and does not need reheating afterwards, since it never cools below the target temperature, as it is never disconnected from the system.
I hope you understand now.
And well, another disadvantage is the unnecessary electricity consumption for all the control components.
