These units operate under demanding conditions — running for extended periods, exposed to pool chemicals, and dealing with wide ambient temperature variations. This service is for homeowners and commercial pool operators whose pool heat pump has stopped heating, is heating slowly, displaying error codes, making unusual noises, or simply not maintaining the set temperature. We work on all major pool heat pump brands including Zodiac, Hayward, Calorex, Thermotec, Fairland, and BWT. Pool heat pumps share the same fundamental technology as domestic air source units but have specific differences in refrigerant types, titanium heat exchangers (to resist chlorine corrosion), and control logic. A general HVAC engineer without pool heat pump experience often misdiagnoses these systems. We attend properties across Hampshire, Berkshire, Surrey, and Wiltshire. Every repair includes full diagnosis, transparent quoting, and a workmanship guarantee. ## What Happens If You Wait? A pool heat pump that fails in spring means your pool sits unused during the warmest months of the year. Every day without heating is a day your significant investment in a swimming pool delivers no return. Pool heat pumps operate in a corrosive environment. Chlorinated water, humidity, and outdoor exposure accelerate component degradation. Delaying repairs allows corrosion to spread from one component to adjacent parts, increasing the repair scope and cost. Many pool owners call their pool maintenance company for heat pump issues. While these companies are excellent at water chemistry and filtration, they rarely have F-Gas certification or the refrigerant circuit knowledge needed to diagnose compressor, expansion valve, or PCB faults. Running a faulty pool heat pump — for example, one with a partially restricted heat exchanger — forces the compressor to work under abnormal pressures. This shortens compressor life dramatically and can turn a minor repair into a full unit replacement. ## How We Work 1 ### Phone Consultation We discuss the symptoms, your pool setup, and the heat pump model to arrive prepared with the most likely parts and diagnostic tools. 2 ### On-Site Diagnosis Full diagnostic check including refrigerant pressures, electrical readings, water flow verification, heat exchanger inspection, and controller analysis. 3 ### Clear Quotation We explain the fault in plain language and provide a transparent quote for the repair before any work begins. 4 ### Professional Repair Components are replaced using correct specification parts. Refrigerant work is carried out to F-Gas regulations with proper recovery and recharging. 5 ### Performance Verification We run the system and verify it is heating the pool water at the expected rate before signing off the repair. ## Why It Matters ### Extend Your Swimming Season A properly functioning heat pump lets you swim from April through October — or year-round with an indoor pool. ### Protect Your Pool Investment Your pool cost tens of thousands to build. A working heat pump ensures you actually use it for the months it should be available. ### Accurate Specialist Diagnosis We understand pool heat pump specific issues that generalists miss — titanium heat exchanger scaling, water flow sensor faults, and defrost logic errors. ### F-Gas Compliant Repairs All refrigerant work is carried out legally and safely by a certified engineer. No unlicensed top-ups or venting. ### All Brands Covered We work on Zodiac, Hayward, Calorex, Thermotec, Fairland, BWT, and other pool heat pump manufacturers. ### Transparent Pricing You know the cost before we start. No surprises, no escalating bills. ## Technical Detail & Expertise Pool heat pumps use titanium heat exchangers to resist the corrosive effects of chlorinated or salt-chlorinated water. Over time, scaling from hard water can reduce heat transfer efficiency even on titanium surfaces. We inspect and, where necessary, descale heat exchangers to restore performance. Many pool heat pumps use R410A or R32 refrigerant, though some older units use R407C. We carry the appropriate refrigerants and recovery equipment for each type. Leak detection on pool heat pumps requires particular care as units are often located in humid, chemically aggressive environments where electronic detectors can give false readings. Water flow through the heat exchanger is critical. Insufficient flow — caused by dirty filters, undersized pipework, or a failing circulation pump — triggers low-pressure cut-outs or freeze protection. We verify flow rates against the manufacturer's minimum specification as part of every diagnosis. Inverter pool heat pumps are increasingly common and offer variable speed operation for better efficiency and quieter running. However, their inverter boards and compressor drive electronics are more complex than traditional on/off units. We have experience diagnosing inverter-specific faults including DC bus voltage errors, IGBT failures, and communication faults between the control board and inverter module. Outdoor installation exposes pool heat pumps to weather, debris, insects, and garden chemicals. We commonly find evaporator coils blocked with leaves, cottonwood seeds, or grass clippings. Capacitors and contactors degrade faster in outdoor environments and are frequent failure points. For commercial pool operators — hotels, leisure centres, swim schools — we understand the urgency of getting the pool back to temperature. Downtime means lost revenue and customer dissatisfaction. We prioritise commercial pool repairs accordingly. ### Related Services - [Swimming Pool Heat Pump Servicing](/services/swimming-pool-heat-pump-service) - [Swimming Pool Heat Pump Supply](/services/swimming-pool-heat-pump-supplier) - [Heat Pump Repair](/services/heat-pump-repair) - [Emergency Repairs](/services/emergency-repairs) - [← Back to Homepage](/) ### Service Areas - [Basingstoke](/areas/basingstoke) - [Hampshire](/areas/hampshire) - [Berkshire](/areas/berkshire) - [Surrey](/areas/surrey) ## Frequently Asked Questions ### How much does a pool heat pump repair cost? ### Can you repair all brands of pool heat pump? ### My pool heat pump runs but doesn't heat the water — what is wrong? ### How quickly can you attend? ### Should I winterise my pool heat pump? ### Can you supply and install a new pool heat pump if mine cannot be repaired? ### Is it worth repairing an older pool heat pump? ### What areas do you cover? ## Get Your Pool Heating Again — Call a Specialist Don't waste another week of your swimming season.
