We’ve encountered situations where DHW settings on dual plate Danfoss HIUs are set excessively high, leading to a range of issues from soaring bills to limescale buildup, leaks, and part failures.

Our dedicated engineers are here to put a stop to unnecessary expenses and energy waste. Through meticulous calibration aligned with manufacturer recommendations, we ensure your Danfoss HIU operates at its peak efficiency. By paying only for what you truly need, you’ll see a marked reduction in energy waste within both your individual flats and the broader communal system. Experience the difference that calibrated precision can make – it’s a step toward optimal performance, savings, and lasting comfort.

In the realm of efficiency, the primary return temperature holds the key. The lower this temperature, the more efficient your system becomes. According to Besa Standards, maintaining a primary return temperature below 25°C during hot water usage and under 40°C while heating is active is optimal.

The Danfoss HIU excels in achieving these benchmarks, provided it’s commissioned and serviced by the right experts. At R&B London HIU Engineers, we’re committed to ensuring your Danfoss HIU operates at its peak potential. With precision aligned to manufacturer recommendations, we guarantee efficient operation that meets and even surpasses BESA Standards.

Our team is dedicated to not only setting your Danfoss HIU correctly but also empowering you to use it in the most efficient manner. When you choose R&B London HIU Engineers, you’re choosing a pathway to efficiency, comfort, and adherence to the highest industry standards.

Ensuring your heating system’s settings align precisely with its type is paramount. The harmony of heating flow temperature and delta T is what drives efficiency and comfort.

For underfloor heating systems, the optimal heating flow temperature shouldn’t exceed 45°C. Conversely, if your system features radiators, we’ll adjust the settings to achieve a maximum of 60°C.

It’s worth noting that a unique phenomenon, where radiators feel warm at the top and cooler at the bottom, indicates a well-balanced system. This balancing act ensures efficient utilisation of heating, facilitated by a lower secondary return temperature.

At R&B London HIU Engineers, we’re all about precision. Our aim is to fine-tune your heating system for peak performance, no matter the configuration. Count on us to navigate the intricacies and optimise your settings, paving the way for exceptional efficiency and comfort.

In our commitment to preserving the integrity of your heating system, our annual service encompasses a crucial step – the meticulous cleaning of the strainer (filter). This meticulous process eliminates debris and sludge buildup, safeguarding against potential flow rate issues and the risk of these particles finding their way into your plate heat exchangers.

At R&B London HIU Engineers, we’re dedicated to going beyond the surface. By prioritising the cleanliness of your system’s components, we’re ensuring optimal functionality, peak performance, and the longevity of your heating solution. Trust us to keep your systems flowing smoothly, so you can experience uninterrupted warmth and comfort year-round.

Your safety is our top priority, and at R&B London HIU Engineers, we take meticulous care of critical components like expansion vessels and pressure relief valves to ensure your peace of mind.

Expansion Vessels: These vessels are essential in maintaining the correct pressure within your heating system as it heats up. Our experienced engineers meticulously inspect and maintain your expansion vessel, safeguarding against pressure-related issues that could compromise the efficiency and safety of your heating system.

Pressure Relief Valves: Managing pressure within your system is crucial for both performance and safety. Our skilled technicians conduct thorough examinations and adjustments of pressure relief valves, ensuring they operate flawlessly. These valves are designed to release excess pressure, preventing potential damage or operational disruptions.

With R&B London HIU Engineers, you’re choosing a team that’s committed to preserving your comfort and security. Our dedication to precision, efficiency, and safety is evident in every service we provide. Trust us to keep your heating systems running seamlessly, so you can enjoy warmth and tranquility without any concerns

In the heart of your HIU lies a silent hero – the pump. This unassuming component is a powerhouse, responsible for circulating water throughout your heating system. At R&B London HIU Engineers, we recognise the vital role of the HIU pump and are dedicated to ensuring its optimal performance.

Unveiling the Function: The HIU pump is the driving force that ensures hot water and heating reach every corner of your system efficiently. Its precise operation guarantees a consistent and comfortable environment, offering you the warmth and convenience you deserve.

Tailoring for Success: Our experienced engineers take customisation to the next level. As part of our comprehensive service, they meticulously adjust the pump’s settings to align with the specific requirements of your heating system and the size of your flat. This precision ensures that the pump operates at its best, optimising energy consumption and minimising any waste.

Expert Calibration: Trust our engineers to fine-tune the pump settings to perfection. By matching the pump’s performance to the demands of your unique setup, we’re not just ensuring efficiency – we’re enhancing the overall functionality of your heating system.

Within the heart of your HIU, a symphony of heating parts orchestrates warmth and comfort. Yet, like any intricate mechanism, these components can encounter the challenge of seizing over time. At R&B London HIU Engineers, we’re well-versed in the art of revitalising these crucial parts to ensure peak performance.

Tackling Seizing: The passage of time and regular usage can sometimes lead to seizing – a phenomenon where heating parts become less responsive. Our seasoned engineers specialise in detecting and addressing this issue during our comprehensive servicing. Through meticulous care and expertise, we free up these parts, breathing new life into your heating system.

Mastering the Thermostatic Valve: Among these components, the thermostatic heating valve holds a significant role. It’s the gateway to controlling the temperature within your system, impacting both comfort and efficiency. Our engineers recognise the importance of this valve and the necessity of calibrating it correctly. During our service, we ensure that the thermostatic heating valve is set accurately, so you can experience the precise warmth you desire.

Preserving Performance: With our meticulous approach to heating parts and thermostatic valves, we’re not just delivering a service – we’re enhancing the longevity and efficiency of your HIU. Our dedication to excellence and unwavering commitment to your comfort drive us to ensure every aspect of your heating system functions harmoniously.
