The invention relates to a method and arrangement for providing heat (Qout) for a district heating supply (40): Heat (Qin) is provided at a first temperature level (T41, T42) by means of a thermal water delivery (20) from a geothermal source (41). By operating a high temperature heat pump (43) and its thermal connection with the geothermal source (41), the thermal water through the evaporator (431) of the high temperature heat pump (43) are passed and its heat (Qin) to the evaporator (431) of the high temperature heat pump (43 ) be transmitted. The condenser (433) of the high temperature heat pump (43) then provides heat (Qout) at a second, higher temperature level (T43, T47) to the district heating network (40). As the high-temperature heat pump (43), a high-temperature compression heat pump (43) is preferably used. The second, higher temperature level (T43, T47) reached above 100 ° C.
