I think the short answer is "no", unfortunately.
The tenants presumably could have (and probably still could) make a claim for damages but not sure whether it would be worth it.
If it's squirting scalding water you, it's a health and safety matter. The council should be interested but probably won't be. I'd report to the student union housing people and send a recorded delivery letter of complaint to the agent.
Not sure you can achieve any more.
