$92 off/$158

Amazon is offering the Bosch Thermotechnology Tronic 4000 6.5kW Electric Tankless Water Heater for $158.40 shipped. Down from $250, it spent the first half of 2023 keeping between its MSRP and $200. It wasn’t until Labor Day sales that we saw it drop further to its former $160 low, which we didn’t see beaten until March when its fell to the new $154 low. Today’s deal comes in as a 37% markdown off the going rate that gives you a solid $92 in savings and returns costs to the second-lowest price we have tracked. This 6.5kW under-sink tankless water heater is designed to provide an endless supply of instantaneous hot water to one or more commercial/residential sinks. It can be installed in a 360 degree orientation, with its 13-inch by 8.5-inch by 4.5-inch size making it easy to fit in tight under-counter spaces, and its low 0.55 GPM activation flow rate works perfectly for commercial low-flow faucets. It boasts a 96% thermal efficiency rate with no standby heat loss, saving you time, water, and money.

If you’re looking for something bigger and more powerful, Amazon is also offering the Eemax 240V 27kW Tankless Electric Water Heater for $405, down from $699. This 240V device provides continuous hot water at a flow rate of 2.7 GPM to 6.6 GPM to multiple sources, depending on the inlet water temperature of your region. For example, with an inlet temperature of 47 degrees Fahrenheit, you’ll get hot water for two water saver shower heads, whereas with an inlet temperature of 77 degrees, you’ll get enough hot water for four water saver shower heads and one hand washing sink simultaneously. Keep in mind, this model will require three 40A breakers, a wire gauge of 3X8 AWG, and a 3/4-inch NPT connection.
