Shower
Question
If you want people to take you seriously, you need to qualify and clarify. You need to say: If you want to take a shower on shabbos you MUST do one of the following: (a) turn off your hot water heater, which means it'll be a cold shower, or (b) Make certain, using a thermometer, or thermostat, but make certain! that the water in your heater is not being heated to a temparture that is above yad soledes bo (whether its 110 or 120 or 125)
Answer
Answered by Rabbi AbadiI thought we did that - thanx for clarifyinf This is not true. The shower will be warm! By the way, since there is a gezerah not to bathe yourself in hot water, but only warm water, what is the definition of "hot" (i e., what temperature ))
