Amazon is offering the Ecosmart ECO 36 36kw 240V Electric Tankless Water Heater for $399 shipped. Normally fetching $749, it saw many discounts over 2023, with the largest among them dropping costs to a $425 low during Black Friday and Christmas sales. Its first 2024 discount just last month saw costs drop further to $413, with today’s deal coming in as an even bigger 47% markdown off the going rate, beating out our previous mention by $14 and marking a new all-time low. This 240V water heater has a 6-gallon capacity and is only 3.6 inches by 21 inches by 17 inches, taking up far less space than a standard water heater while being “99.8% energy efficient and saving you 50-60% on heating costs.” Its sleek and compact design features a digital output temperature display, and fits pipes with a 3/4-inch NPT. It does require a 4 x 40A breaker.

If you’re looking for a smaller or cheaper option, Amazon is also currently offering the EcoSmart ECO 18 Electric Tankless Water Heater for $325, down from $425. It offers the same operating features as the above model with some slightly less impressive specs. It has half the amperage at 75A and can provide 1.8-gallons to 4.3-gallons per minute depending on the inlet water temperature and is only 17 inches by 14 inches by 3.75 inches. It fits the same 3/4-inch NPT pipes as above, but only requires 2 x 40A breakers instead.

You can also check out the ongoing deal for the iHeat 120V 3.2KW Tankless Electric Under-Sink Water Heater that boasts an IXP4 waterproof construction with a waterproof interactive pad, and can be used in highly sterile applications such as commercial kitchens, hospitals, clinics, and schools.
