ᐅ Which air-to-water heat pump is suitable for a new build?

Hello,

for the new build, we plan to install an air-to-water heat pump. The brands mentioned are Vaillant, Viessmann, or waterkotte. What would you recommend for an area of about 110 square meters (1,184 square feet) with low noise levels?
Oh, and it will be an outdoor installation.

First, you need to have the required heating load calculated.
