Update: Amazon has dropped the price to $559 shipped.

Amazon is offering the Bosch Tronic 6100 27kW Electric Tankless Water Heater for $624.73 shipped, after clipping the on-page 5% off coupon. Down from a $749 price tag, it saw a fair share of discounts over 2023, bouncing between its MSRP and a $656 low. Since the start of 2024 we’ve already seen one major discount a month ago that dropped costs down to a new $520 low. Today’s deal comes in as a smaller 17% markdown off the going rate and lands at the third-lowest price we have tracked – $105 above the all-time low.

This 27kW under-sink tankless water heater is designed to provide an endless supply of instantaneous hot water to one or more sinks, or to appliances like washing machines. 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, even 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.

Amazon is also offering the Marey Power Pak 12 kW Electric Tankless Water Heater for $138. This 220V tankless water heater provides a maximum of 2 points of use and up to 2.2 GPM at 35-degrees Fahrenheit temperature rise.
