ᐅ Air-to-water heat pump – smart thermostat

Own goal! (Just to match your level! That’s all I’ll say about it). Luckily, as an IT specialist, you have the best physics knowledge.

I didn’t hear this from anywhere else; I am speaking from real experience and can compare with the other five houses in the neighborhood that were built using the same technology and have similar sizes, etc.

I am the only one among these six without an ERR, and now guess who has the lowest heating costs...

Did everyone build your house? Install your heating system? But your heating settings are based on EER?
I have significantly lower heating costs thanks to EER than my neighbors, so what?
These are all meaningless statements (including my own).
I’ll stop with the off-topic now and leave you to your opinions.

Fully agree with Mycraft. I have lived in two houses with ground source heat pumps. One had a mechanical ventilation system without a fireplace; the heating only worked properly when all the valves were fully open and, of course, the heating curve was adjusted down. The heat pump needs to run for as long as possible until the return temperature is reached.
Now in a single-family home with a ground source heat pump without mechanical ventilation and without a fireplace, it’s the same. If the sun is too strong, you just have to ventilate for longer.
The thermal mass of the floor is far too slow to react quickly.

How gracious of you.

To give you one last thought for the night and to simply turn your own statements around:

Your ever-popular solar gains—according to you, without ERR (energy recovery ventilation), lead to overheating. But that is complete nonsense, because with ERR the room is actually suppressed; it heats up. The underfloor heating doesn’t transport heat anywhere in this case; it just keeps heating up, so to speak.

Without ERR and with proper hydraulic balancing, the system transfers the heat and distributes it across the entire system. And don’t even try to say the whole house overheats—no one generates that many solar gains during the heating season.

The self-regulating effect of the underfloor heating as a slow thermal mass is responsible here. This effect is destroyed by the ERR...

But I’m just a simple IT guy who isn’t about to argue with a physicist. At least I know how to use quotes properly.

Forget it – these are just individual opinions that don’t mean anything. The practical examples are just nonsense as well.

And yes, I admit it – I am guilty. I read up on the topic – what else was I supposed to do? I didn't actually learn it...

But luckily, my heating engineer used exactly the same arguments without me having to ask. That’s how I knew I got a good one.

Saruss will probably come in soon with comments about the usefulness of a 1000-liter (264-gallon) buffer tank...
