1. Introduction
This manual provides comprehensive instructions for the safe and efficient operation of your Quality Heating 30L Double Electric Boiler. Please read all instructions carefully before installation and use, and retain this manual for future reference.
The Quality Heating 30L Electric Boiler is designed for efficient and reliable hot water supply. This electric boiler features an 'Extra Life' design, offering extended lifespan and high energy efficiency (Energy Class A).
With a 30-liter capacity and 1500 Watt power, this boiler includes simple, mechanical control. It features 40mm insulation with a conductivity coefficient of λ= 0.22, resulting in minimal heat loss (less than 0.2 °C per hour).
This electric boiler is suitable for various applications, including apartments, hair salons, riding schools, and garages, particularly in areas without gas connections. A 30-liter boiler can provide approximately 79 liters of hot water (at 37°C) when mixed with cold water, sufficient for one person's needs.

2. Safety Information
Your safety is paramount. Please observe the following safety guidelines:
- Electrical Safety: Ensure the boiler is connected to a properly grounded 220 Volt electrical supply. Do not operate with damaged cords or plugs. Disconnect power before any maintenance or repair.
- Water Pressure: The boiler is equipped with an overpressure protection system. Do not tamper with the safety valve.
- Installation: Installation must be performed by a qualified professional in accordance with local regulations and plumbing codes.
- Temperature: Hot water can cause severe burns. Exercise caution when using hot water and ensure children are supervised.
- Internal Protection: The boiler features 6 layers of advanced protection, including heat protection, dry-run protection, overpressure protection, corrosion protection, electrical protection, and thermostat control.
- Anode Tester: An anode tester with an alarm is integrated to monitor the sacrificial anode, which protects against corrosion.

3. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your electric boiler. It is recommended that installation be carried out by a certified technician.
3.1 Unpacking
Carefully remove the boiler from its packaging. Inspect for any signs of damage. Report any damage to your supplier immediately.
3.2 Mounting Location
The boiler is designed for indoor wall mounting. Choose a location that is:
- Capable of supporting the boiler's weight when full (18 kg dry weight + 30 kg water = 48 kg).
- Protected from freezing temperatures.
- Easily accessible for maintenance and operation.
- Close to water supply and electrical connections.
3.3 Dimensions
The product dimensions are approximately 53 cm (Length) x 28 cm (Width) x 95 cm (Height).

3.4 Plumbing Connections
Connect the cold water inlet and hot water outlet pipes. Ensure all connections are watertight. Install the included safety valve on the cold water inlet according to local plumbing codes.
3.5 Electrical Connection
Connect the boiler to a dedicated 220 Volt electrical circuit. Ensure the circuit is protected by an appropriate circuit breaker. The boiler uses a standard electrical cable for power supply.
4. Operating Instructions
The Quality Heating 30L Electric Boiler features a user-friendly digital control panel for temperature adjustment.
4.1 Initial Startup
- Ensure the boiler is completely filled with water before switching on the power. Open a hot water tap to allow air to escape until water flows steadily.
- Switch on the electrical power supply to the boiler.
- The digital display will illuminate.
4.2 Temperature Adjustment
Use the control knobs on the front panel to set your desired water temperature. The digital display will show the current temperature setting. The adjustable temperature range is typically between 30°C and 75°C.

4.3 Heating Cycle
Once the desired temperature is set, the boiler will begin heating the water. The heating indicator (if present) will illuminate. The boiler will automatically maintain the set temperature.
5. Maintenance
Regular maintenance ensures the longevity and efficiency of your Quality Heating boiler.
- Anode Inspection: The boiler is equipped with an anode tester and alarm. If the alarm activates, it indicates that the sacrificial anode needs inspection or replacement. The anode protects the tank from corrosion. Consult a qualified technician for anode replacement.
- Draining and Cleaning: Periodically drain and flush the boiler to remove sediment buildup. This should be done by a qualified professional.
- External Cleaning: Clean the exterior of the boiler with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Safety Valve: Periodically check the safety valve for proper operation. Refer to the safety valve manufacturer's instructions.
6. Troubleshooting
If you encounter issues with your boiler, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | No power supply Thermostat set too low Heating element failure | Check circuit breaker Adjust thermostat setting Contact a qualified technician |
| Insufficient hot water | Thermostat set too low Excessive hot water usage Sediment buildup | Increase thermostat setting Allow time for reheating Schedule professional flushing |
| Water leaking | Loose connections Faulty safety valve Tank corrosion | Tighten connections Replace safety valve Contact a qualified technician |
