According to more than one source I found, they actually have four hearts (there even seems to be a little ambiguity in some sources as to whether there might even be five, probably depending on what's considered a "heart"). What is fairly clear in any case, though, is that all these hearts pump blood to a different region or organ (a one-chambered "portal heart" supplies just the liver sinusoids). Considering that the hagfish has such a long, narrow body and all its hearts seem to be located near its head from all the diagrams I've seen, I'd infer that it would be infeasible for it to have a single heart large or strong enough to do all that work.
