A Case Study in Heating System Optimisation
Client: Mrs E, Homeowner Location: Surrey Service: Automatic Bypass Valve Installation & System Balancing

Mrs E was experiencing a common but frustrating problem in her home: some radiators remained cold while others were too hot, leading to uncomfortable rooms and an inefficient heating system. Our team at Boilers2Ac LTD identified the root cause and implemented a solution by installing a 22mm Automatic Bypass Valve and rebalancing the entire system. The result was consistent, even heating throughout her home, improved energy efficiency, and a very happy client.
The Challenge: Cold Radiators and Wasted Energy
Mrs E contacted us because she was struggling with uneven heating. Despite her boiler firing up, several radiators, particularly those furthest away, failed to get warm. This not only made parts of her home uncomfortably cold but also suggested her heating system was working inefficiently, potentially leading to higher energy bills and unnecessary strain on her boiler.

A system without proper regulation often suffers from issues caused by a faulty or missing bypass valve. This can lead to:
Poor Circulation: Hot water takes the path of least resistance, bypassing radiators and returning to the boiler without distributing heat where it's needed.
Reduced Efficiency: The boiler runs longer to try and heat the cold rooms, wasting energy and increasing fuel costs.
Boiler Short-Cycling: The rapid return of hot water can trick the boiler into thinking the home is warm, causing it to shut down and restart frequently, which reduces its lifespan.
Our Solution: A Targeted Approach to System Health
We understand how disruptive heating problems can be, so our goal was to provide a swift and effective solution. Our process involved three key steps:
Thorough Diagnosis: Our engineer conducted a full assessment of Mrs E's heating system. We confirmed that the lack of a bypass valve was causing poor circulation and pressure imbalances, which was the primary reason for her cold radiators.
Bypass Valve Installation: We installed a 22mm Automatic Bypass Valve at an optimal point in the system. This component is designed to automatically regulate water flow, ensuring that even when other radiator valves are closed, the system maintains the correct pressure and circulation, preventing the boiler from overworking.
Complete System Balancing: After fitting the valve, we meticulously balanced the system. This involved adjusting the lockshield valve on every radiator to ensure that each one received the right amount of hot water, guaranteeing even heat distribution across the entire house.

The Results: A Warm Home and Peace of Mind
Immediately following our visit, Mrs E experienced a significant improvement. Every radiator in her home now heats up evenly and efficiently.
The key benefits achieved were:
Consistent Comfort: All rooms now reach their desired temperature, eliminating cold spots.
Improved Energy Efficiency: By ensuring the system operates as intended, energy is no longer wasted, leading to more manageable heating bills.
Enhanced Boiler Protection: The new valve prevents short-cycling and reduces strain, helping to extend the lifespan of her boiler.
"I was so frustrated with my cold radiators and had almost given up hope. The team from Boilers2Ac didn't just fix the problem; they explained everything so clearly. Now, my entire house is finally warm and comfortable. I couldn't be happier with the service and the result."- Mrs E, Homeowner
Conclusion
This case demonstrates that seemingly complex heating issues often have straightforward, effective solutions. By correctly diagnosing the problem and implementing a targeted fix, we were able to restore comfort and efficiency to our client's home. It’s a testament to how a small, professional adjustment can make a huge difference to your home's warmth and your peace of mind.
