Air-to-water heat pump - Nest Thermostat

I told you - he can't do it

Own goal! (Just to get down to your level! I won't say more about that). Luckily, as an IT specialist, you have the best physics knowledge.

I didn’t pick it up anywhere but can draw on real experiences and compare it with the other 5 houses in the neighborhood that were built with the same technology and have similar size etc... I am the only one of these 6 who has no ERR and now guess who has the lowest heating costs...

Did everyone build your house? Install your heating? But your heating settings are EER? I have significantly lower heating costs with 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 opinion.

Full agreement for Mycraft. Have lived in two houses with a ground-source heat pump. One with [ERR] without a fireplace, the heating only really worked when all the regulators were fully open. And of course lowering the heating curve. The heat pump has to run as long as possible until the return temperature is reached. Now in a single-family house with a ground-source heat pump without [ERR] and fireplace the same. If the sun shines too strongly, you just have to ventilate longer. The floor mass is far too sluggish for a quick reaction.

I'm going to stop with the off-topic now and leave you to your opinion.

How gracious

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

Your ever-popular solar gains - according to you lead to overheating without ERR. That is exactly complete nonsense, because with ERR the room is throttled, it heats up. The underfloor heating doesn't transport anything here, so to speak it heats up even more excessively.

Without ERR and with the appropriate hydraulic balancing, the system removes the heat and distributes it to the overall system. And don’t you dare come up with the whole house overheating now – nobody produces that many solar gains here during the heating phase.

The self-regulating effect of the underfloor heating as a sluggish heat storage is responsible here. This is destroyed by the ERR...

But I am just a stupid IT guy who simply has nothing to oppose to a physicist. At least I know how to use quotations correctly .

Forget it - they are just individual opinions that mean nothing. Likewise, practical examples - all rubbish.

And yes, I admit it - I am guilty. I have read up on the topic - what else am I supposed to do? I didn’t learn it...

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

Saruss will surely come along soon with the usefulness of a 1000l buffer tank...
