* See Igrot Moshe 1:94 who writes that it is permitted to return food to an oven on Shabbat if it can't be used for cooking during the week, doesn't reach Yad Soledet Bo, and there's no fire since then it wouldn't appear to be an issue of cooking on Shabbat.

* Rabbi Muschell ([http://www.star-k.org/kashrus/kk-cooking-ovenshabbos.htm star-k.org]) writes that if the warming drawer reaches above 120 degrees one may not place food in there on [[Shabbat]]. Rather he writes that one may leave food in there from before [[Shabbat]] on a few conditions. If the temperature is adjustable the knob must be covered. If opening the warming drawer is thermostatically controlled one may only open the drawer once on [[Shabbat]], removing everything at one time. Similarly, on another page, the [http://star-k.org/cons-appl-wolf-warmdrawer.htm Star-K] writes that all food should be placed in the drawer before [[Shabbat]] and may not be placed there on [[Shabbat]]. The drawer may be opened only once and so one should remove all food at one time. Additionally, the Star-K writes, that one should cover the knobs and the temperature certainly may not be adjusted on [[Shabbat]].</ref> Some of the stringent opinions would permit if there's no knob to adjust the temperature.<ref> Rabbi Mordechai Willig ("The Laws of Cooking and Warming Food on Shabbat" p. 127) writes that reheating cooked food in a warming drawer is permitted since it doesn't look like cooking. However, the knobs must be covered so that it is extremely inconvenient to adjust the temperature. Rav Hershel Schachter (ibid. p. 181) argues that covering the knob is insufficient unless there is no knob to adjust the temperature.</ref>

===Radiator===
# Some poskim hold tha tit is permitted to take food out of the refrigerator and place it on the radiator since it would not be seen as a way of cooking, while other poskim hold that it is like a covered fire and one may not return food there without the conditions of Hachzara.<ref> Rabbi Eider in Halachos of [[Shabbat]] (p. 313) rules that one may place food on a radiator. See also Shemirat [[Shabbat]] KeHilchata 1:30, who argues that a radiator is like a covered fire upon which one may not return food to it on [[Shabbat]] without fulfilling the other conditions of [[Hachzara]].</ref>
