It does a good job of quickly heating the water within a few seconds. However, you need to know a few things before ordering it. Per the item description, it works best with a limited flow faucet. The water gets quite hot with a 0.5CFM faucet, just barely warm enough for a shower with a 1.0CFM faucet, and does a good job of taking off the chill with a 1.5CFM faucet. Its rated at 3000watts (25Amps) of electrical power. My home is fairly new construction and has a 20Amp circuit breaker for the bathroom. The heater drew 2600Watts (22Amps) for 30 seconds and then the circuit breaker popped. You will need a 25-30Amp breaker to power this heater. Review: Good while it works .... lasted 6 months before it died - Requires a dedicated outlet to prevent breaker from tripping, running for more than a few minutes can sometimes trip the dedicated breaker as well. Purchased in February, finally got in installed by mid June. It just stopped working in November. To get the water more than just warm water flow has to be low, barely enough to wash your hands. Used in work shop and was able to get the pressure where it worked for me. While it was working I gave it a 3 or 4, but since it worked barely 6 months it gets the one star it deserves ## Features - With 3000W power, the water heater can raise the water by 45° F(0.3GPM) /27° F(0.5GPM) in seconds. You can adjust the water flow to meet your outlet temperature requirement. The Larger water flow, the lower outlet temperature; The smaller water flow, the higher outlet temperature. Not Suitable for Shower(Shower normally requires at least 1.8 gpm). You can set Fahrenheit or Celsius degrees by holding power button for 6 seconds. - IMPORTANT PRE-PURCHASE NOTES: This device with a power of 3000W at 110V draws a maximum current of 27A.

Purchased in February, finally got in installed by mid June. It just stopped working in November. To get the water more than just warm water flow has to be low, barely enough to wash your hands.

The operation is pretty simple. You set the temperature by regulating the flow of water. The device has various protections, but it always operates at maximum power, so to increase the temperature you need to reduce the flow. Keep it away from water or steam as the electronics inside are not waterproofed whatsoever. ## Frequently Bought Together - Generic Tankless Water Heater Electric, Instant Hot Water Heater Under Sink, 3000W 110V On Demand Mini Water Heater for RV Kitchen Bathroom, White - TDRSUPER Bottle Water Dispenser Pump System Self-Priming 110V AC US Plug Drinking Water Pump Single Tube Food Grade Suitable for Coffee/Tea Maker, Water Dispenser, Refrigerator, Ice Maker - North Mountain Supply 5 Gallon Vented Plastic Hedpak/Carboy --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/610299264-generic-tankless-water-heater-electric-instant-hot-water-heater-under](https://www.desertcart.us/products/610299264-generic-tankless-water-heater-electric-instant-hot-water-heater-under) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-24*
