INNOVACERA ceramic heater uses 92% or 95% alumina ceramic tube with a screen-printed resistance circuit . The ceramic heating tube is suitable for compact tankless water-heating assemblies. For a smart toilet ceramic heater or ceramic heater for bidet applications, ceramic heater performance depends on the complete operating condition rather than wattage alone. Water flow, inlet-water temperature, target outlet temperature, supply voltage, available space and control method all need to be considered. INNOVACERA can make the ceramic heater according to drawings and module requirements.

Water-Heating Test Data
The following data provides a reference for evaluating the ceramic water heater element in instant water-heating systems.
| Test Parameter | Test Data |
|---|---|
| Inlet water temperature | 10–30°C / 5–7°C |
| Water flow rate | 500 mL/min |
| Heater power | 1600 W ±7% |
| Outlet water temperature | 40 ±1°C |
Actual outlet-water temperature depends on inlet-water temperature, water flow, supplied power, water-path design and control logic.
Reliability Test Data
A bidet water heating element may switch on and off repeatedly during normal use, so cycle performance and electrical insulation are important design considerations.
| Test Item | Test Result |
|---|---|
| Start/stop cycle test | More than 100,000 cycles |
| Test condition | Rated-voltage water operation |
| Dry-heating test | 850°C / 24 h |
| Insulation resistance | >500 MΩ |
| Leakage current | <0.5 mA |
Typical Applications
| Application | Heater Function | Main Engineering Focus |
|---|---|---|
| Smart Toilet Instant Water Heating | Heats wash water as it passes through the ceramic tube | Outlet temperature, water flow, electrical safety and cycle life |
| Bidet Seat Water Heating | Works as a ceramic heater for bidet wash-water systems | Fast response, repeated operation and voltage matching |
| Instant Water-Heating Module | Integrates with the water path, sensor and control system | Heater power, thermal control and protection logic |
Customization and Heater Selection
For OEM and design-in projects, INNOVACERA can customize the MCH heater for smart toilet or bidet applications according to the electrical and mechanical requirements of the complete module. Available adjustments include supply voltage, heating power, resistance, tube dimensions, heating-zone position, terminal configuration, electrical connection and mechanical interface.
For initial evaluation, please provide the following information:
| Required Information | Purpose |

Frequently Asked Questions
What is a tubular MCH heater used for in a smart toilet?
It heats wash water as it flows through the heater, allowing the smart toilet or bidet seat to provide warm water without a large storage tank.
What voltage options are available?
The current tubular MCH heater platform supports 110-120 V and 220-240 V systems.
What is the maximum power?
The heater is available with power up to 1600 W.
What water flow has been tested?
Representative testing has been carried out at 500 mL/min with heater power of 1600 W ±7%. The recorded outlet-water temperature was 40 ±1°C.
Is cycle-life data available?
Yes. More than 100,000 start/stop cycles have been recorded under rated-voltage water conditions.
Can the heater dimensions be customized?
Yes. Voltage, power, resistance, dimensions and heating-zone layout can be adjusted according to the customer’s module requirements.
Does inlet-water temperature affect heating performance?
Yes. Outlet-water temperature depends on inlet-water temperature, flow rate, heater power and the complete water-path and control design.
