Abstract

In an arrangement for charging a hot-water tank (1) by means of a heat pump (2), the heat pump (2) is connected to an intermediate heat exchanger (4) via a forward-run pipe (3) and a return-run pipe (5). This exchanger is in turn connected to the hot-water tank (1) via a forward-run train (6) and a return-run train (7). Arranged in one of the trains (6, 7) is a circulating pump (8). The circulating pump (8) can be connected into the forward-run pipe (3) as of a minimum temperature and can be disconnected when the temperature falls below this value. The circulating pump (8) is moreover controllable in such a manner that its delivery capacity falls with falling temperature in the forward-run pipe (3) and vice versa. <IMAGE>
