In scandinavia, there exists almost only electric and heat-pump boilers.

Denser metropolitan areas have "district heating", which means water-transported heat that can be generated remotely by boilers, but there are also heat-pumps on these networks. For example, buildings can "sell" heat into the network with heat-pumps. Data centers do this.

Thank you - district heating looks like a great topic to learn more about; I hadn't really considered that the same principles behind feeding back into the (electric) energy grid could apply for thermal energy too.
