Responsa for Shabbat 288:2
וממאי דרבנן היא דילמא ר' יהודה היא ותהוי נמי ר' יהודה אימר דשמעת ליה לר' יהודה יצאו מעצמן סוחטין לכתחילה מי שמעת ליה אלא מאי אית לך למימר כיון דלאו בני סחיטה נינהו אפילו לכתחילה אפילו תימא רבנן כיון דלאו בני סחיטה נינהו אפילו לכתחילה ש"מ רבנן היא ש"מ
And how do you know that this is the [ruling of] the Rabbis: perhaps it is R. Judah['s view]? — Even granted that it is R. Judah['s]: when have you heard R. Judah [to permit the juice], when it exudes of itself: have you heard him [to rule that] we may express it at the very outset?<span class="x" onmousemove="('comment',' Surely not. ');"><sup>3</sup></span> But what you must answer is since they are not intended for pressing, [it is permitted] even at the outset; consequently even if it is assumed to be the ruling of the Rabbis, since they are not intended for pressing [it is permitted] at the very outset. Hence it follows that this [agrees with] the Rabbis [too].<span class="x" onmousemove="('comment',' For the same logic holds good on their view too. ');"><sup>4</sup></span>
Maharach Or Zarua Responsa
R. Hayyim Eliezer recalls that one time, the winterhouse was once heated by a Gentile on the Sabbath, and his father refused to eat therein. R. Samuel of Falaise in the name of R. Yom Tov permitted one to dwell in a winterhouse that was warmed by a Gentile on the Sabbath. In our city, most of the people rely upon this decision and dwell in winterhouses that are warmed by Gentiles on the Sabbath.
