Is it possible to use the hot water from a faucet on yom tov in which the water is heated by a tank-less water heater. Tank-less water heaters do not store hot water. Rather, when the hot water faucet is opened the heating mechanism is turned on and the water is then heated. Any recommendations?
Although we are allowed to bring a existing fire from one place to another on yom tov, we are not allowed to ignite or make a fire anew. Causing the mechanism to start would be included in this. Personally I don’t know of any ideas. If anyone has, I’d be happy to hear them.
