Because the temperature spread a given heat pump uses isn't really suitable for district heating, your output water would only be in the 50 to 60°C range at most, too low for typical district heating systems. One can get around that with multi-stage heat pumps or different coolants, but both are expensive investments typically not viable for existing systems.
- nine_k 4y agoIf it's not enough for district heating because of the distance and heat losses, it could be enough for a greenhouse right next to a DC. Economically the greenhouse would have a distinct advantage of using free heat, and already having enough electricity wired nearby. This, of course, only makes sense during cold seasons, or somewhere like Alaska or Sweden. During hot months, 40-50°C of heat seem completely useless. Maybe next to a sea such waste heat could help evaporatively desalinate seawater, while cooling back to reusable temperatures.
