Domestic Hot Water Heating vs Efficiency of Air-to-Water Heat Pump

That is certainly honorable, but outside the specific boundary conditions of your BV, not at all usable!!!! There is a lack of comprehensive, responsible professional competence here! In other words, what is quite reasonable and purposeful for you might, under other specific boundary conditions, possibly be an economic money pit! Are you aware of this and can you also classify and take responsibility for this professionally?

Hello Wastl, hello Perlenmann,

Thank you for the numbers as a reference point. Regarding the set temperatures, these are the values that the installer from the heat pump manufacturer has set. We are currently reaching about 45 °C maximum temperature in the shower water, so it is certainly possible to reduce it by another 5 °.

Best regards

That is certainly honorable, but outside the specific boundary conditions of your construction project, absolutely not applicable!!!! There is a lack of overarching, responsible professional expertise here! In other words, what makes sense and is effective for you might, under other specific boundary conditions, possibly be a financial disaster! Are you aware of this or can you professionally assess and take responsibility for it?

Sorry €uro, for such an unproductive "babble" my time is too precious.

I am capable of looking beyond my own horizon and do not limit myself to my own field when I share experiences as a client.

The purpose of my posts in this forum is definitely not to threaten other forum members with financial catastrophes in order to secure lucrative contracts for myself.

Nor am I a candidate for yellow and red cards in other forums.

Find someone else who lets you get involved in pointless discussions.

which is equipped with an air-water heat pump that also heats the domestic hot water. For this purpose, there is a buffer tank maintained at 50 °C and a fresh water station that then heats the hot water.

I am too stupid, I don't understand it.
What is the purpose of the fresh water station if there is a buffer tank for domestic hot water heated by the heat pump??

Regarding the question of consumption for hot water: 1.3 kW, with two people and a flow temperature of 43° during summer heating operation. However, brine.

Hello, The buffer tank is not for domestic water but for a closed circuit. The fresh water station is, as far as I understand, a heat exchanger that then takes heat from this buffer. The advantage is supposed to be that at lower temperatures you have fewer problems with legionella. Best regards Christian
