Based on a quick search, the typical costs for installing a vertical system to a single-family home are 15k to 25k euros in Finland. The contractors I found seem to discourage horizontal installations unless the bedrock is unusually deep. Drilling bedrock is cheap, while horizontal pipes have to be much longer, because the ground gets cold in the winter.

Horizontal systems just need a backhoe to install, as you only need to dig below the frost line (we also get down to about -40 in winter). Vertical drilling requires more specialized equipment and so is more costly. Vertical systems are about $10k more expensive than higher end horizontal systems.
