To keep your Megaflo system operating safely and efficiently, regular servicing by qualified professionals is essential. While Megaflo cylinders are well-engineered for minimal maintenance, periodic inspections help sustain performance and prevent issues from developing. Expert servicing provides peace of mind that your hot water system is working correctly with no leaks, electrical faults, or safety concerns.

Servicing Procedures and Charging

Regular maintenance of your Megaflo unvented cylinder is essential to keep it operating efficiently and safely. Our technicians perform a comprehensive service check that includes:

Draining and Recharging the Air Gap

The air gap inside the cylinder is critical for performance. It should be recharged at least once yearly as it can deplete over time. We will partially drain the cylinder and recharge the air gap properly.

Testing Valves, Thermostats, and Connections  

A vital part of the service is testing all valves, thermostats, and electrical connections. We check zone valves on Combination Loop (CL) models and measure immersion heater resistance on Direct (DD) models. Thermostats are tested for proper continuity and operation, ensuring all components function correctly.

Assessing for Issues

In addition to scheduled maintenance, our technicians inspect for any problems or deficiencies that may impact the system's operation and longevity. We thoroughly check all components and provide recommendations if repairs or replacements are needed. Proper servicing helps avoid unnecessary repairs down the road. Our experts keep your Megaflo performing optimally.

Warning Signs of Poor Installation or Maintenance

Many issues arise from improper installation or lack of maintenance of Megaflo systems. Improper installation or lack of maintenance highlights the importance of professional servicing to prevent problems and ensure longevity.

Some warning signs to look out for include:

Dripping tundish: The tundish is designed to drain water in case of issues with the pressure relief valve. If you notice water dripping from the tundish, it likely indicates a problem with the valve that requires servicing.

Electrical issues: Faulty wiring or connections can cause a loss of power to the heating elements or other electrical components. Signs may include intermittent operation, tripped breakers, or scorched/melted wires or connections.

Strange noises/smells: Any abnormal sounds, such as banging, hissing, or unusual odours, may signal a leak, sediment buildup, or component failure. Don't ignore these red flags. 

Loss of hot water performance: If you notice a decline in hot water capacity, temperature, or recovery time, it could point to sediment buildup, element failure, thermostat problems, or other maintenance issues.

Don't hesitate to contact us if you notice any of these or other unusual signs in your Megaflo system. Timely servicing can prevent minor problems from becoming big headaches down the road. Our experts can troubleshoot issues and keep your hot water running optimally.

Case Study: Poor Installation Highlights Need for Expert Servicing 

We've seen firsthand the disastrous effects of unqualified tradespeople on Megaflo systems. Just last year, we received an emergency call to a home in Salford where a faulty installation may have led to a dangerous electrical fire. 

The homeowners had hired a "handyman" to install their new Megaflo cylinder, but the handyman lacked the proper training and expertise. Critical mistakes were made during the installation, allowing water to leak into the electrical connections and eventually causing a dangerous short circuit and fire. Thankfully, the homeowners were not injured, but the entire Megaflo unit and water damage throughout the home were destroyed. This alarming example underscores the absolute need to have Megaflo systems installed and maintained by qualified professionals. 

Our expert technicians have the experience and Megaflo-specific training to spot issues and perform maintenance to avoid catastrophic system failures. Take your time with your home's plumbing and heating systems. Trust DDWilson to keep your Megaflo running safely and efficiently.
