Specialist Gledhill PulsaCoil repairs in London
Facing a loss of hot water, an overheating immersion heater, or an unexpected leak? Our factory-trained London engineers provide round-the-clock emergency diagnostics, genuine manufacturer spares, and dependable same-day restorations across London.
Understanding the Gledhill PulsaCoil 3
A well-known thermal store across London flats and developments, the PulsaCoil 3 remains a popular open-vented cylinder. Water within the store is heated using off-peak and on-peak immersion elements, transferring heat rapidly to incoming mains cold water through an external plate heat exchanger (PHE). Dual store and DHW sensors, alongside a dedicated Grundfos pump, regulate flow rates to maintain consistent hot water after an initial 30-second warm-up period.
While older than models such as the PulsaCoil 2000, A-Class, and modern Stainless Eco ranges, an existing PulsaCoil 3 can still be repaired and fully serviced by our engineers. Routine electrical testing, sensor replacements, and PHE descaling will keep your system running reliably. However, if the main cylinder itself suffers an internal leak, a complete replacement with a modern stainless steel thermal store is required.

Safe decommission and removal of obsolete PulsaCoil units, followed by seamless supply and installation of modern, highly efficient thermal stores with full manufacturer warranty.
Why PulsaCoil systems demand dedicated specialists
Unlike unvented cylinders governed by standard G3 regulations, Gledhill PulsaCoil units are open-vented thermal stores packed with intricate printed circuit boards, relays, and sensitive sensors. General plumbers frequently misdiagnose these units. Our certified engineers possess specialised Gledhill factory training, advanced electrical competency, and thermal store expertise across the PulsaCoil 3, PulsaCoil 2000, PulsaCoil A-Class, and PulsaCoil Stainless ranges.
Common PulsaCoil faults we resolve
PulsaCoil units rely entirely on internal immersion elements and header water volumes. Common faults include burned-out heating elements, tripped high-limit safety thermostats leaving the store stone cold, low water levels in the top-up cistern stopping heat transfer across the coil, and faulty delivery pumps or flow switches preventing hot water reaching your taps.
