6. Installation Requirements & Setup
The Briwellna water heater is designed for easy self-installation, requiring no plumber. However, it is crucial to ensure your electrical system meets the specified requirements.
Electrical Requirements:
Before purchase and installation, verify that you have the proper electrical requirements for your chosen heater. To install a Briwellna P33, you must have enough room in your breaker panel to dedicate:
- For 5500W models: A 25A double pole breaker solely for the unit.
- For 3800W models: A 35A double pole breaker solely for the unit.
Installation Steps:
The unit offers 360° unrestricted installation, meaning it can be mounted in various orientations. The display can be adjusted if the product is installed upside down.
- Choose Location: Select a suitable location in your kitchen, bathroom, laundry room, or other workspace. Ensure it's not in a freezing environment or near flammable materials.
- Mount Unit: Use the provided hooks and hanging nail to securely mount the main unit. The insulation wall should be used as directed.
- Connect Water Lines: Connect the cold water inlet (blue) and hot water outlet (red) to your plumbing system using the provided T-junction and temperature control valve. The water connection size is 1/2 inch.
- Ensure Water Flow: Before connecting power, turn on the water supply and ensure water flows through the unit normally. This prevents dry-burning.
- Connect Electrical: Once water flow is confirmed, connect the electrical wiring to the dedicated circuit breaker as per the electrical requirements. The unit comes without a plug and requires direct wiring.

9. Troubleshooting
If you encounter issues with your water heater, refer to the following common troubleshooting tips. For persistent problems, contact customer support.
- No Hot Water:
- Check if the unit is powered on and the display is active.
- Ensure water supply is open and flowing through the unit.
- Verify that the electrical circuit breaker has not tripped.
- Confirm that the water pressure meets the minimum requirement (0.04-0.8MPa).
- Water Not Hot Enough:
- Adjust the temperature setting using the control keys to a higher value within the 30-55°C range.
- Check the incoming water temperature, as it affects the output temperature.
- Ensure the water flow rate is not too high, as higher flow rates can reduce output temperature.
