# Many Sephardic poskim are lenient to do Shehiya in an oven from before Shabbat. Some poskim add that one should cover the buttons and other poskim add that one should place a tray or aluminum foil on the bottom of the oven to cover the heating element.<ref> Yalkut Yosef 253:6 writes that it is permitted to do Shehiya into an oven before Shabbat. It is a stringency to cover the buttons. Tefillah LMoshe 1:2 writes that an oven is a covered fire and it is sufficient to cover the knobs to remind oneself not to change the temperature and then it is permitted to do Shehiya into an oven. Or Letzion 2:17:4 writes that one may do Shehiya in an oven if one can cover the heating element with a tray or aluminum foil.

===Hot Water Urn=== | |||
#The only way to leave water in a hot water urn from before Shabbat is by turning it on several minutes before Shabbat so that the water reaches at least Yad Soledet Bo before Shabbat. Otherwise the leniencies of covering the fire or using raw meat are inapplicable.<ref> Igrot Moshe 4:74:23 requires that it have time to boil. 39 Melachos fnt. 183 writes that it seems Rav Moshe was concerned that if it was only left on so that the water would become Yad Soledet Bo, although shehiya was avoided, nonetheless if htey took out some water before it boiled that would be forbidden since it would cause the rest of the water to boil quicker. However, he quotes Chazon Ish and Rav Shlomo Zalman Auerbach who disagreed as long as the water is Yad Soledet Bo, which is the temperature necessary not to violate shehiya (Igrot Moshe 4:74:24).</ref> | |||
