District Heating Sweden

This document contains preliminary numbers for economic data for Swedish district heat. The number cover only the consumptions side of district heat, that is what the cost of using district heat as a heating source

It is assumed that we can make the split between smaller houses (single homes) and bigger buildings/houses (public, commercial and multi family houses).

“Area served/ power/ price of exchanger X” data points referse to an unspecified heat exchnager from a retailer, listed in the source, and is used to generate new datapoints such as regression data and averages. Each table only contain one type of heat exchanger. Bold font rows are the final datapoints.

The values are good approximations, but they may still be subject to change.

Establishing a relation between the power of a heat exchanger and the area heated by said heat exchanger
