Hello,
we are building a city villa with 230 sqm (2,476 sq ft), KFW 55 standard. We are planning the following technology:
- Air-to-water heat pump Waterkotte Eco Touch DA 5010, series DA 5018
- with a 225-liter (60-gallon) buffer tank for the heat pump, 390-liter (103-gallon) hot water tank
- Ventilation system Waterkotte Eco Vent
- Photovoltaic system 8.1 kWp “Silver Line Heckert STP8.000TL” with E3/DC S10 E 2Z, 4.6 kWh battery storage
- All underfloor heating, all windows with electric blinds
- Piping prepared for a future water-based pellet stove
Construction site is in Schleswig, 24837.
What do you think, does this setup make sense? It’s difficult to get good advice here, so we would like to ask some “regular” consumers about their experiences.
Thank you very much

I don’t think this combination is very well planned—it sounds like a standard maximum profit setup by the general contractor or plumber.

The buffer tank has nothing to do with the fireplace and is too small for that purpose. It will need to be replaced later with a minimum capacity of 500–900 liters (130–240 gallons), depending on the fireplace output.
Why doesn’t the buffer tank fit or work well together? I’m not familiar with that.
The building services come from a different company than the rest, since they want all devices from one manufacturer and the other company couldn’t provide that.
I would like to move toward a hybrid system to keep the power consumption of the heat pump low, using the fireplace for support in winter and my own electricity in summer.
@nordanney are you satisfied with the device?

You already have 8 kWp of solar panels on the roof (which is the most effective way to support heating with a heat pump)... so what heating costs are you expecting?! Without anything else, they are usually only around 500-600 € per year... with solar probably about half... none of this will pay off in 100 years.
(just a rough guess)
