Dialysis machines and methods for heating dialysate before delivery into a dialysis patient (e.g., peritoneal dialysis machines) may comprise a dialysis machine including one or more internal cooling components configured to expel heated air from the dialysis machine. A receptacle may be configured to receive one or more containers of dialysate. The one or more containers of dialysate may be positionable relative to the expelled heated air of the dialysis machine. The expelled heated air may be flowable around the one or more containers of dialysate to increase a temperature of the dialysate. The receptacle may include a stand for positioning the dialysis machine such that the expelled heated air is directed around the one or more containers of dialysate.
