There is a project for deep geothermal heat in Finland. They specifically chose to do it here as it is one of the worst places to do it (have to drill really deep to get anything useful also the first 4 to 5km is just pure bedrock instead of some softer material).
So they ended up making 6.4km deep holes where they got 121 degree (celcius) water. Once pumped up to ground level it cools down to 110 degrees but it is more then hot enough for district heating.
The original plan was to got 9km deep but it was already hot enough at 6.4km so they stopped there to save money.
