Product Description

Instant Water Heater Control Board

Instant water heater control board is the central electronic module that manages the heating process, temperature regulation, and safety features of tankless (instant) water heaters. It monitors water flow and temperature in real time to provide efficient, on-demand hot water while protecting the system from overheating, dry burning, and electrical faults.


Choig is a leading manufacturer specializing in instant water heater control boards, offering both standard products and extensive customization services.We supports:

Application of Instant Electric Water Heater Control Board


Extendable Solution Areas

1. After adjustment, the knob control solution can be developed;

2. After simplification, it can be changed to an indicator light display scheme;

3. Can be adjusted to gear control scheme according to market needs


4. The constant temperature parameters can be adjusted according to different heating elements, such as cast aluminum heating element, steel cup (copper cup, plastic cup) heating element, bare wire heating element, quartz tube heating element, etc;

5. Can be control by WIFI and OTA service;

Extended Solution Areas for Temperature Control System

1. Enhanced Knob Control Solution

· Ergonomic & Multi-Functional Design: Redesign knobs for intuitive use (e.g., push-pull for on/off, rotation for temperature).

· Integrated Digital Display: Combine analog knobs with a small screen to show real-time temperature or power levels.

· Tactile Feedback: Add haptic responses for precise adjustments (e.g., "clicks" for incremental changes).

· Customizable Resistance: Allow users to adjust knob stiffness for safety or preference.

2. Simplified Indicator Light Display

· Color-Coded Status: Red (heating), Green (ready), Blue (standby), Yellow (error).

· Dynamic Modes: Blinking for alerts (e.g., overheating), pulsing for active modes.

· Touch-Activated Controls: Integrate capacitive touch with indicator lights for minimalist interaction.

· Adaptive Brightness: Auto-adjust LED intensity based on ambient light.

· Energy-Saving Mode: Dim lights during inactivity or low-power states.

3. Adaptive Gear Control Scheme

· Preset Gear Modes: Low (40°C), Medium (60°C), High (100°C) for common use cases.

· Customizable Gears: Let users define temperature/performance settings per gear via app.

· Automatic Gear Switching: AI-driven adjustments based on usage patterns (e.g., high gear for rapid heating).

· Safety Lock: Restrict access to high-temperature gears without a passcode.

4. Heating Element-Specific Temperature Customization

Different heaters have many differences in heating efficiency, performance, and temperature. Therefore, in terms of constant temperature regulation, we can combine some sensors to achieve fast and stable output in temperature control and regulation of water heaters, which requires some experience accumulation and technical mastery. We have provided a variety of electronic control solutions for instant water heaters with various types of heaters, such as cast aluminum heaters, steel cup heaters, bare wire heaters, etc., and have received good feedback.

5. Smart Connectivity (WiFi/OTA)

· Remote Control: Adjust temperature, gears, or schedules via mobile app.

· OTA Firmware Updates: Deploy performance enhancements or new material profiles remotely.

When stop operation the Zero line and live line will be shut off both(for controller with pump)

1. Meet EU energy efficiency standards (standby power consumption <1W)

Specific value:

 Energy saving and consumption reduction: Standby power consumption less than 1W significantly reduces users' long-term electricity costs, especially suitable for high-price areas in Europe, saving tens of euros in electricity bills each year.

 Environmental compliance: Comply with EU ErP directive and other regulations, avoid market access barriers, and support green energy transformation goals.

 Technical competitiveness: Adopt low-power chips, intelligent sleep algorithms and efficient power management modules to reflect the company's technical research and development strength.

Application scenarios:

 Home users: Reduce "invisible power consumption" in standby mode and enhance the environmental image of products.

 Commercial scenarios (hotels, gyms): Save energy costs under large-scale equipment clusters.

2. Assist in passing EMC testing (electromagnetic compatibility)

Specific value:

 Reliability guarantee: Ensure stable operation of equipment in complex electromagnetic environments (such as no interference when using microwave ovens and WiFi at the same time) to reduce failure rates.

 Global market access: Comply with EN 55014, IEC 61000 and other standards, and support export to high-demand markets such as the EU and North America.

 Brand trust: Avoid safety hazards caused by electromagnetic interference and enhance user trust in product quality.

3. Wide voltage power supply (AC 90V~260V)

Specific value:

 Global applicability: Compatible with unstable voltage in underdeveloped areas (such as some Asian and African countries) and standard power grids in developed countries, without the need for additional voltage stabilizers.

 Anti-interference ability: Built-in wide voltage adaptive circuit to deal with abnormal situations such as lightning strikes and power grid fluctuations, extending the life of the equipment.

• Installation flexibility: Suitable for old buildings or temporary power supply scenarios (such as construction sites and RVs).

4. High constant temperature accuracy (±0.5°C, 10 seconds stable)

Specific value:

 Ultimate user experience: There is no large fluctuation in water temperature when bathing and washing dishes, avoiding the pain point of "hot and cold", especially suitable for mothers and babies and the elderly.

 Technological breakthrough: Using PID algorithm + high-precision NTC sensor to compensate for water flow and voltage changes in real time (such as multiple taps using water at the same time).

 Energy saving and efficiency improvement: quickly reach the target temperature, reduce preheating waiting time and energy waste.
