Can one use an electric hot water heater on Yom Tov- the heater is a 50 gallon tank
Answer:
It is not clear what you mean by “using the heater”. If the intent is to remove hot water for use which will indirectly cause more water to enter the tank this would be permitted on Yom Tov. To activate the electric device on Yom Tov directly would be prohibited as with activating any electric device.
