I do it every year and am ok, If she isnt living there draining pipes
anyway is smart since heating systems do break, if its a boiler with
radiators depending on how pipes are run, it may ruin pipes by turning
down the system if boiler pipes are are close to exterior walls and
freeze on the coldest nights.
