TLDR: Service your heat pump yearly to protect efficiency, catch faults early, and keep warranty paperwork clean. A proper service covers cleaning, system checks, electrics, pressures/temperatures, and hot water safety checks, then you get a written report. 

If you’ve invested in a heat pump, you’ve made a smart choice for energy efficiency and lower-carbon heating. But like any heating system, it needs regular maintenance to keep it running efficiently and safely. If you’re searching for reliable heat pump servicing in Gloucester, annual servicing is essential to protect performance and extend the lifespan of your system.

At Hewer Facilities Management, professional heat pump servicing ensures your system remains safe, efficient, and compliant. Here’s why it matters, what’s included, and answers to common questions homeowners and businesses often have.

 

Why Regular Heat Pump Servicing Is Essential

Renewable Installers Gloucester

Heat pumps operate year-round to provide heating and hot water. Over time, components can wear, pressures can fluctuate, and dirt can accumulate inside critical parts like the evaporator and magnetic filter. Even small changes can quietly reduce efficiency and increase energy costs.  The Energy Saving Trust explains that properly maintained heat pumps can significantly lower energy use compared to traditional heating systems. Efficiency, however, depends on routine inspection and correct system setup.  Servicing also helps maintain manufacturer warranties, as many require annual maintenance records. Without documented servicing, your warranty could be invalidated.

 

What’s Included in a Professional Heat Pump Service?

A full heat pump service is far more than a simple visual check. During a service from Hewer Facilities Management, a qualified engineer performs a comprehensive system inspection.  The process includes reviewing the overall condition of the unit, performing safety and operational checks, and identifying any existing or potential faults. The evaporator is brush cleaned to maintain airflow efficiency, while refrigerant temperature differentials are checked to ensure optimal heat transfer. Electrical voltage testing confirms safe operation, and interface settings are inspected to ensure the system remains correctly configured.

Actuators, pumps, and sensors are all tested, and magnetic filters are cleaned to remove debris.  Fluid health is assessed, including glycol levels and or anti-freeze valve inspection. Water pressure is adjusted if necessary, and strainers are released to ensure unrestricted flow.  Additionally, the hot water cylinder is visually inspected, and either a legionella cycle check or a 3kW immersion heater test is carried out to ensure safe domestic hot water operation.  After the service, an electronic detailed service report is sent via email. While parts and labour for repairs are not included, any issues identified will be quoted before further work proceeds. No additional support is included beyond the service, except for any parts covered under manufacturer guarantee.
