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.
Nothing beats a nice hot shower, regardless of the month (in my opinion), and it’s that time of the year when folks are noticing places around their homes or vacation houses that need some updating. Camplux’s 18kW unit not only ensures things stay steamy, but its compact form factor ensures far less space is taken up compared to traditional water heaters. You’ll also find various alternate sizes ranging from 8kW to 27kW on the same landing page, depending on your needs.
Once installed, according to Camplux, you won’t have to “wait more than 3 seconds to get plenty of hot water,” with the fast-heating low-consumption heating rods boasting “efficiency up to 99.8% and saving 60% water heating costs for your home.” There are plenty of safety protections built right in, like against overheating, anti-dry heating, water-electricity separation, and more. Do keep in mind though that it requires a minimum 0.66GPM water flow to activate, as well as two double-pole 40A breakers, a wire gauge of 2 x 8 AWG, and a 3/4-inch NPT connection.
For even more eco-friendly tech that you can incorporate into your home life, there are plenty of hangover savings in our weekly Electrified roundup from Saturday, or you can browse the latest in our Green Deals hub.
