Common Heat Pump Problems We Diagnose

Most heat pump issues aren't caused by a faulty unit. They come from poor system design, incorrect setup, or controls that were never configured properly problems that should have been picked up at installation.

If your system isn't performing as it should, it's usually one of these:

  • High electricity bills

  • House not reaching temperature

  • Fault codes and alarms

  • No heating or hot water

  • Underfloor heating not working properly

  • Heat pump running constantly

  • Short cycling

  • A system that needs repairs an installer missed the first time

How We Support UK Homeowners

Our approach is simple: you send us your system details, photographs, and any documents you have, and we carry out a structured technical assessment.

Many heating engineers are excellent at plumbing and heating systems but may not work with heat pumps regularly. Where needed, we can work alongside your existing engineer remotely through you, helping them understand what adjustments, investigations, or repairs may be required.

In many cases, the issue is simpler than people think. If the problem relates to settings, controls, system pressure, filter cleaning, or general operation, we can often guide homeowners through the process themselves. Where further work or repairs are needed, we help identify the most likely cause and explain the practical steps involved.

We review heat loss calculations, flow temperatures, radiator sizing, system layout, control configuration, and overall system performance, giving you clear, honest answers based on real-world heat pump experience.

With more than 100 years of combined experience in the heating industry, we've worked on hundreds of heat pump systems, providing everything from design reviews and commissioning support to optimisation, fault diagnosis, and repairs.

Why UK Heat Pump Help Is Different

When your heat pump isn't performing, your installer often has a commercial interest in the answer. They may say the system is fine, blame the house, or suggest expensive upgrades. We have no interest in any of that.

We don't install systems. We don't sell equipment. We don't subcontract to installers. We review your system and give you an honest technical assessment so you know exactly where you stand, and what to ask for.
