Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Meet the EcoSmart 3500 W Tankless Electric Water Heater—the compact, on-demand solution your home deserves. Designed for residential use, this unit brings instant hot water to where you need it most without the bulk of a traditional storage tank. Perfect for apartments, small homes, or under-sink installations, it’s a smart way to upgrade comfort without sacrificing space.

  • Power and performance: 3500 watts at 120 volts, drawing up to 29 amps to deliver hot water on demand for a single fixture at a time.
  • Ultra-compact footprint: only 7" tall, 11" wide, and 3" deep, with bottom water connections (1/2" diameter) for flexible, space-saving mounting.
  • Temperature control: adjustable from 60°F to 140°F, so you can dial in comfortable, consistent hot water for sinks, showers, or laundry without temperature swings.
  • Safety and certification: CSA listed for residential use and protected by a 1-year warranty for peace of mind.
  • Tankless efficiency advantages: on-demand heating means no standby heat loss, helping you avoid paying to keep a tank hot when it isn’t needed.
  • Important installation note: Temperature Pressure Relief Valve is not included, so plan for compliant safety measures in accordance with local codes.

What makes this EcoSmart model stand out

Unlike bulky storage tanks, the EcoSmart 3500 W Tankless Electric Water Heater delivers hot water exactly when you need it, right at the point of use. Its compact design and bottom 1/2" connections simplify installation in tight spaces, making it an ideal choice for under-sink setups, single-bath apartments, or dedicated utility niches. The unit’s residential focus, CSA listing, and straightforward 60–140°F temperature range provide practical, reliable hot water for everyday tasks—from quick hand-wwashing to a refreshing rinse after a shower.

Who this is ideal for

  • Renters or owners in small living spaces seeking reliable hot water without sacrificing room.
  • Installers looking for a compact, easy-to-wire point-of-use solution on a 120V circuit.
  • Homes that prioritize energy efficiency by eliminating standby heat loss associated with storage tanks.

Practical tips for getting the most from your unit

  • Plan installations where hot water demand is concentrated at a single faucet or shower to maximize performance.
  • Use the 60–140°F range to tailor comfort while protecting sensitive skin from temperature shocks.
  • Verify local codes regarding a Temperature Pressure Relief Valve and ensure proper safety provisions are in place.
  • Keep the 1/2" bottom connection in mind during plumbing design to simplify the line layout and reduce backflow potential.

With the EcoSmart 3500 W Tankless Electric Water Heater, you gain a practical, space-conscious solution that brings dependable hot water to compact living spaces. It’s a thoughtful upgrade for modern homes where efficiency, ease of installation, and precise control matter most.
