As heat pump installations continue to grow across the UK, installers are delivering increasingly efficient systems designed to provide long-term performance, lower energy consumption and reliable comfort for homeowners.
But as many engineers are finding in the field, achieving long-term system performance is about more than just selecting the right heat pump.
At Spirotech, we believe system water quality and contamination control are becoming increasingly important considerations for installers looking to protect system efficiency, reduce future maintenance issues and help avoid unnecessary callbacks.
Like any heating system, heat pump installations can accumulate debris over time, including magnetite, dirt and installation residue circulating within the system water. Because heat pumps operate with lower temperatures and more precise flow conditions, maintaining clean and stable system water becomes even more important for preserving consistent performance and protecting sensitive components.
When contamination builds up within the system, installers may begin to see issues such as reduced flow, increased wear on components or unnecessary strain on the system over time.
For installers, preventing these issues early can help support long-term reliability and customer satisfaction long after commissioning has been completed.
Designed specifically for modern heat pump systems
This growing industry focus is one of the reasons Spirotech developed the new SpiroTrap HPF (heat pump filter).
Rather than adapting an existing product, the SpiroTrap HPF has been specifically engineered for modern heat pump systems, using insights gathered from years of research into system contamination, water quality and real-world installation conditions.
As part of the development process, Spirotech researched residential heat pump systems across several European countries to better understand:
- the types of contamination commonly found in systems
- the components most vulnerable to dirt accumulation
- the practical servicing requirements installers face on site
The result is a filtration solution developed specifically to support the long-term efficiency and reliability of modern heat pump installations.
The SpiroTrap HPF combines three key technologies:
- a powerful magnet
- a fine 160 μm mesh filter
- Spirotech’s SpiroTube technology
Together, these components help capture both magnetic and non-magnetic dirt particles before they can circulate through the wider system.
The unit also features a completely bypass-free design, ensuring all system water flows directly through the filter for continuous protection.
Developed with installers in mind
At Spirotech, we know installers are looking for products that not only protect system performance but also make installation and servicing as straightforward as possible.
That is why the SpiroTrap HPF has been designed with practical installation and maintenance in mind.
One of its standout features is the new MultiMode Swivel, allowing installers to quickly switch between normal operation, backflush mode and closed mode using a simple and intuitive control.
The backflush function allows trapped dirt to be removed quickly and cleanly without unnecessary disassembly or additional tools, helping make routine maintenance faster and easier on site. The filter has also been designed to align with standard heat pump maintenance intervals.
Additional installer-focused benefits include:
- highly efficient dirt filtration
- protection against both magnetic and non-magnetic debris
- low-maintenance operation
- easy installation across multiple connection sizes
- minimal pressure drop
- robust brass construction
- a 10-year warranty for long-term confidence
As heat pump systems continue to become more common across both retrofit and new-build projects, installers are increasingly recognising the importance of whole-system protection in supporting long-term efficiency and reliability.
See the SpiroTrap HPF at InstallerSHOW 2026
Ahead of InstallerSHOW 2026, Spirotech is inviting installers to explore how effective system protection can help support the long-term performance of modern heat pump systems.
Visitors to the Spirotech stand will be able to see the new SpiroTrap HPF up close, explore its installer-focused design features and speak with technical specialists about best practice for maintaining clean and efficient heating systems.
As the industry continues to evolve, the conversation around heat pumps is increasingly focused on whole-system performance, helping installers deliver efficient, reliable systems that continue performing as intended long after the initial install.
