Coming at us by way of its official Amazon storefront, Camplux is offering discounts across its line of tankless electric water heaters, with shower times kept plenty steamy through the 18W Tankless Electric Water Heater at $259.98 shipped. This newer generation model dropped down from its original $350 price tag back at the top of 2025 to the $240 low, and has been steadily increasing in price since, with things plateauing recently around $290. While it’s not the lowest we’ve seen, it is a solid opportunity for anyone who missed out on the lower rates we saw earlier in the year, letting you get your home or lake house prepped for the seasonal visits. You’ll be able to add it to your home with $30 off the new going rate at the third-lowest price we have tracked – just $20 from the low.
