Hello everyone,
In our future house, an air-to-water heat pump from Daikin (Altherma 3 R ECH2O 308/508 H/C (H) (Biv) 8kW) will be installed. We now want to replace the analog heating thermostats with digital ones. Since there are countless options available, I wanted to ask here if you could recommend any. They don’t need to be smart home compatible.

But I’m trying to replace the ERR with something more practical. For example, I’m looking for a system with integrated sensors (temperature, humidity, motion, etc.) that communicates via wireless protocol.What is the goal—what exactly do you want to control and how? For example, if someone moves in the room, do you want the underfloor heating temperature to increase so it’s warm three hours later? Depending on your goals, there might be different or more effective solutions.The room thermostats in our previous house also displayed temperature values. However, in the new house, the thermostats only show numbers ranging from a snowflake symbol up to 6. There is also a dot next to “4.” I asked the builder about this, and he said that temperature values are not exact anyway. So now they use numbers—you adjust to whichever setting feels comfortable.

Is it possible to control regular radiators better with smart devices? Do they respond faster? It doesn’t matter whether they’re smart or not. When you turn up a radiator, hot water immediately flows through it, and you instantly notice a measurable effect on the room temperature. Underfloor heating, on the other hand, can take several hours to warm up (and of course, it also takes time to cool down unless you open the windows) – it’s much slower to respond.
That’s why heating systems, especially underfloor heating in new buildings, are designed precisely around the occupants’ needs so you don’t need to keep adjusting the controls. Large temperature fluctuations are rare in new constructions anyway.

That’s why, in heating system installations, especially in new builds (underfloor heating), the system is designed exactly to the residents’ needs so you don’t have to adjust the controls anymore – in fact, you often don’t even need them. Large temperature differences no longer exist in new buildings anyway.I’m still a beginner in this area. But how do I solve the “problem” of wanting 25°C (77°F) in the living room and bathroom, but only 18°C (64°F) in the bedroom? And how can I have 25°C (77°F) in the living room only when I’m at home, but not during the whole day or at night? I understand that underfloor heating is slow to react. So my idea was to set the desired temperature for each room several hours in advance and then let it cool down earlier as well. Doesn’t that work?
