Description
Ultra-Compact Versatility for Any Space:This 2.5-gallon lightweight electric water heater is engineered to fit where traditional tanks can’t. Whether you need instant hot water for your kitchen sink, a guest bathroom, or even an RV, its space-saving design delivers reliable performance without taking up valuable cabinet or floor space—perfect for condos, apartments, and small homes.
Smart Temperature Control & Energy Savings:Equipped with a high-efficiency, direct-heating element, this unit maximizes heat output while minimizing power draw. Easily dial in your ideal temperature from 30°C to 65°C (86°F–149°F) with a simple twist. Once the set temperature is reached, the unit automatically switches to standby insulation mode, maintaining the desired heat level without continuously drawing full power. This smart cycling reduces standby energy loss and over-heating—helping you save on monthly hydro bills while keeping hot water ready whenever you need it.

This electric water heater comes built-in with overheat protection, pressure relief control, and a leakage-protection plug that instantly cuts power if a fault is detected. The rugged casing also provides splash resistance, giving you peace of mind in wet environments like bathrooms or laundry rooms—because in Canada, we know water and electricity don’t mix.
DIY-Friendly Installation with Clear Steps:Designed for hassle-free mounting, this unit includes everything you need for a quick wall installation:① Drill two leveled holes and secure the hooks;② Hang the electric water heater and attach the included one-way safety valve;③ IMPORTANT – Always fill the tank with water and open a tap to purge air before plugging in.Note: A slight drip from the safety valve is normal during pressure regulation.
Heavy-Duty Performance with Local Electrical Compliance:Rated at 1500W / 120V / 10A / 60Hz (compatible with standard North American outlets), this electric water heater is built for consistent performance even during our cold Canadian winters. Always use the original leakage-protection plug and keep the outlet dry to ensure long-lasting, trouble-free operation.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $7 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for ERFEI products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
