Description

Product Overview

The DOYXC 3000W electric tankless water heater is engineered to bring instant, on‑demand hot water to any point‑of‑use application without the bulk and inefficiency of traditional storage tanks. Constructed from high‑grade, heat‑resistant polymer housing and a stainless‑steel heating element, the unit delivers a maximum output of 3000 watts at 110 volts, providing a flow rate of up to 2.9 microliters per minute and reaching temperatures as high as 131 °F. The integrated LED display offers real‑time temperature readouts, while the dry‑combustion protection system automatically shuts off power if water flow ceases, preventing overheating and extending component life. Designed for under‑sink mounting, the heater measures just 4.53 inches wide by 8.87 inches high and weighs only 2.57 pounds, making it an ideal solution for space‑constrained environments such as apartments, tiny homes, RVs, and even outdoor camping setups. The unit operates silently, thanks to its brushless motor and variable frequency drive, which adjusts power consumption based on flow demand, delivering high efficiency while reducing electricity costs.

Usage

Designed with versatility in mind, this tankless heater excels in a variety of real‑world scenarios. In a modern kitchen, it can be installed directly beneath a sink to provide immediate hot water for dishwashing, cooking, and beverage preparation, eliminating the need to wait for a tank to heat up.

FAQ

How does the dry‑combustion protection work?

The dry‑combustion protection sensor continuously monitors water flow through the heating element. If the flow drops below a safe threshold, the sensor triggers an automatic shutdown, preventing the element from overheating and protecting both the device and the surrounding plumbing.

Can the temperature be set in both Celsius and Fahrenheit?

Yes. By pressing the on/off button for a few seconds, the unit toggles between Celsius and Fahrenheit display modes, allowing users to select their preferred temperature scale for precise control.

Is the unit compatible with standard 110‑volt household outlets?

Absolutely. The heater is designed to operate on a standard 110‑volt, 60‑Hz electrical supply, drawing up to 3000 watts. It can be plugged into a dedicated circuit or a properly rated outlet to ensure optimal performance.

What is the maximum flow rate and how does it affect temperature?

The heater can deliver up to 2.9 microliters per minute. As flow rate increases, the temperature may slightly drop due to the higher volume of water passing through the heating element. The variable frequency drive automatically adjusts power to maintain the set temperature as closely as possible.

How easy is the installation process?

Installation is straightforward thanks to the pre‑fabricated mounting brackets and clear instructions. The unit mounts securely under a sink using standard plumbing connections. Most users can complete the installation in under an hour with basic tools, and no specialized plumbing experience is required.
