ECOTOUCH ECO140S 14kW 240V Tankless Water Heater — Instant Hot Water for 2–3 Sinks

Overview

The ECOTOUCH ECO140S is a compact 14kW, 240V tankless water heater designed to deliver hot water on demand at the point of use. Built for reliability, it couples a self‑modulating system with durable components to support everyday needs in kitchens and bathrooms without the lag of a traditional tank.

How it delivers hot water

Water is heated on demand, producing 120℉ or higher within seconds. A smart control chip watches temperature and flow up to 20,000 times per second, minimizing fluctuations as you draw hot water from multiple fixtures.

• Up to 3.38 GPM flow supports 2–3 fixtures simultaneously or a comfortable shower.
• Instant hot water without preheating delay.

Safety, durability, and reliability

ETL certified and UL-qualified, ECO140S uses separate water and electricity lines to reduce leakage risk and scale buildup. It includes leakage protection, over‑temp protection, high voltage protection, and dry‑heating safeguards for dependable operation over time.

Energy efficiency and cost considerations

The self‑modulating design adapts power in real time to match demand, helping balance comfort with energy efficiency. While results vary by usage, this approach aims to minimize energy waste compared with bulky tank systems, keeping hot water readily available when you need it.

Installation and use

Key requirements include 240V power and a maximum draw of 58A. For proper installation, plan a 60A double-pole breaker and 6 AWG/2 wires with grounding. Pipe fittings are 1/2" NPT, and the unit measures about 11 1/5" W x 15 4/5" H x 2 4/5" D, suitable for indoor spaces with adequate clearance.

What you get and maintenance tips

• Minimal maintenance due to separate water and electrical paths and robust internal protections.
• Compact footprint fits into tight indoor spaces without sacrificing performance.
