Alternative air-water heat pump to Weishaupt WBB 12-A RMD-AI?

We are looking for an alternative air-to-water heat pump to Weishaupt WBB 12-A RMD-AI. Which manufacturer and model are comparable? We want to use the heat pump with a hot water storage tank and buffer storage.

Thank you very much!

Hi,
You need a lot more information for a recommendation.

What additional information is needed? I have the complete offer. I am interested in which manufacturers are recommendable in terms of price/performance for the above model, e.g. Viessmann, Vaillant, Wolf, etc.

New building, old building, size, NAT, heating load, people, which buffer exactly for what. Hydraulics... etc

It is a new apartment for 2 people (130 m2 living space) through a complete additional floor. The heat pump will be only for this apartment. The other apartments will keep the current heating situation.

It is really sad. All relevant information is still missing. Not even irrelevant ones have been mentioned for any kind of advice. Should we also google the heat pump model for you?

Do you go to car forums in the buying advice section and ask: "DS 7 E-Tense 225 Performance Line+ Auto - good?"
