The last answer assumes it is an electric water heater. Modern tankless gas units also require AC power, but a very small amount of draw. It should be fine for those. They often have a small exhaust fan, so you should still check the load. Also, there are backups designed just for this, that have a water flow sensor so that they only provide power when it's actually needed for hot water.
Sorry, there was a problem. Please try again later.Check the wattage needed and calculate volt-amps needed. Double this number for safty factor. This should get you started.
Sorry, there was a problem. Please try again later.Thank you for your question! Tankless water heaters require a significant amount of power, often between 3,000 to 12,000 watts, which is much higher than what a 1500VA UPS (900 watts) can provide. A UPS wouldn't be ideal for this, as it isn't designed to handle the high wattage needs of a tankless water heater. For backup power, you'll need a generator or a more robust power solution designed for high-wattage appliances.
