Amazon offers the Marey 4 Gallon 120V Electric Mini Water Heater for $157.53 shipped, after clipping the $40 discount coupon on the page. It's typically priced somewhere between $170 and the original $200, but there weren't many discounts leading up to its fall release, ending 2023 with just seven discounts in total. Today's deal includes a 21% discount off the current price, beating our previous mention by $5 and bringing the cost down to the fourth-lowest price we've tracked – which is just $17 over the all-time low. Capable of storing four gallons of water, this mini water heater is a perfect under-the-sink solution if your water continues to run cold. With a maximum pressure of 150 PSI and a heat range of 77 to 171 degrees Fahrenheit, this mini water heater provides hot water on demand with a quick adjustment of its knob and a flick of your faucet handle. Installation is easy: just connect the heater to the water pipe at the location of your sink and you're ready to go.
If you're looking for a much larger water heater that can meet your household's needs, you'll find that the Camplux 27kW Electric Tankless Water Heater is also discounted on Amazon $368.99 shipped, down from $450. It promises 24 hours of hot water on demand (80 to 140 degrees) and is designed to supply multiple points of consumption at the same time. All that is required is a minimum flow rate of 0.66 GPM when connected to a 3/4″ pipe thread.
And if you still have a standard water heater somewhere in your home and just need a boost to its heating output, check out our previous coverage of the EcoSmart Electric Water Heater Booster, a 240V water heater designed to run on a tank is designed to ensure an increase in hot water production, increasing efficiency and performance by 45% while saving space and costs for hot water production.
