Common Electric Boiler Faults We Diagnose & Repair
Electric boilers are highly reliable, but faults do occur — particularly as equipment ages, in hard water areas, or where installation or wiring issues are present. Below are the most common problems our engineers are called to resolve.
Tripping Circuit Breaker or Fuse
A frequently tripping MCB or fuse typically indicates a failed heating element drawing excess current, a short circuit within the boiler, or an undersized electrical supply circuit. Our engineers carry out full electrical diagnostics to identify the root cause safely.
Failed or Limescaled Heating Elements
Heating elements degrade over time and are particularly vulnerable to limescale build-up in hard water areas such as London and the Home Counties. A failed element results in no heat or hot water; heavy scaling causes significant efficiency loss.
Faulty PCB (Printed Circuit Board)
PCB failures can produce a wide range of symptoms — from intermittent operation and unresponsive controls to persistent fault codes or complete loss of function. Accurate diagnosis is essential before replacement.
Thermostat & Temperature Sensor Faults
A faulty thermostat can result in a boiler that cycles erratically, fails to reach the set temperature, overheats, or runs continuously. Both are diagnosable and typically repairable in a single visit.
Pressure Loss & System Leaks
Repeated pressure loss usually indicates a leak within the system, a failing expansion vessel, or a faulty pressure relief valve. Our engineers investigate the root cause rather than simply re-pressurising, preventing recurrence.
Motorised Valve & Pump Faults
Seized valves, failed actuators, and pump failures result in partial or complete loss of heating to specific zones or the whole system. These are mechanical faults our engineers are experienced in resolving efficiently.
Error Codes & Control Faults
Our engineers are trained to interpret manufacturer-specific error codes across all major brands, correctly identifying whether the fault is electronic, mechanical, or related to the wider heating system.
Boiler Not Switching On
The cause may be a blown internal fuse, a wiring fault, a failed relay, a safety lockout triggered by a prior fault, or loss of incoming electrical supply. Our engineers carry out a systematic diagnostic to pinpoint the problem rather than guessing.

Why Electric Boilers Are an Increasingly Popular Choice
Electric boilers suit a wide range of property types and are particularly well-suited to properties without a mains gas supply, new-build flats, or any property where the owner wants to reduce reliance on fossil fuels.
No Gas Supply Required
Electric boilers are the natural heating solution for properties off the gas grid — rural homes, island properties, and any building where extending a gas main is impractical or uneconomical.
100% Efficient at Point of Use
Every unit of electricity consumed is converted directly to heat — unlike gas boilers, which lose energy through flue gases. The rated output is always delivered to the heating system, with no wastage.
Lower Maintenance Costs
With no combustion, no flue, and fewer mechanical components than a gas boiler, electric boilers are inherently simpler and typically require less maintenance. There is no annual Gas Safe inspection requirement.
Compact & Quiet Operation
Electric boilers are typically much smaller than equivalent gas models and produce no combustion noise — well-suited to flats and properties where space or noise is a concern.
Zero Operational Emissions
When connected to a green electricity tariff or on-site renewable generation, an electric boiler produces no direct carbon emissions. As the UK grid decarbonises, the carbon footprint reduces automatically.
No Flue, No Combustion Risk
Electric boilers produce no combustion gases, eliminating the risk of carbon monoxide. This is an important safety consideration for high-occupancy properties and landlords with statutory safety obligations.

Frequently Asked Questions
We offer same-day and emergency call-outs across London and the Home Counties, typically arriving within 1–2 hours of your call. Our engineers carry diagnostic equipment and a comprehensive range of replacement parts, maximising the chance of resolving the fault in a single visit.
The most common faults we repair include failed or limescale-coated heating elements, faulty PCBs, thermostat malfunction, pressure loss, tripping circuit breakers, motorised valve failure, and fault codes being displayed. Our engineers carry out thorough diagnostics to identify the root cause and resolve it correctly first time.
Yes. Although electric boilers have fewer moving parts than gas boilers, annual servicing is strongly recommended. A service includes inspection of heating elements, electrical safety checks, system pressure and flow testing, thermostat calibration, and a full diagnostic scan. Regular servicing maintains efficiency, extends the lifespan of the unit, and is often required to keep manufacturer warranties valid.
We repair and service all major electric boiler brands including Heatrae Sadia, Elnur, Thermaflow, Trianco Aztec, Strom, EHC, Electromax, Comet, Amptec, Atlantic, and many others. Our engineers have hands-on experience with a wide range of models across both residential and commercial applications.
Yes. We carry out full electric boiler installation projects, including switching from gas to electric heating. Our engineers will assess your property, advise on the most suitable boiler type and size, handle all wiring and pipework, ensure compliance with Part L Building Regulations, and activate your manufacturer warranty.
Electric boilers are 100% efficient at the point of use — all the electrical energy consumed is converted directly to heat. However, the overall carbon footprint depends on how the electricity is generated. When powered by renewable energy, electric boilers produce zero operational emissions.
Gas Safe registration is not required for electric boiler work, as no gas supply is involved. However, all electrical installation and repair work must be carried out by a qualified electrician, and certain work falls under Part P of the Building Regulations. Our engineers are NICEIC registered, ensuring all work meets current UK regulatory standards.
A tripping circuit breaker is usually caused by a failed or short-circuiting heating element, a faulty PCB, wiring faults, or an overloaded circuit. This should always be investigated by a qualified engineer — repeated tripping indicates a developing fault that will worsen if left unattended.
With proper installation and regular annual servicing, a quality electric boiler typically lasts between 15 and 25 years. Electric boilers have fewer mechanical components than gas boilers, which contributes to their longevity. Regular servicing, prompt attention to minor faults, and descaling in hard water areas are the most effective ways to maximise working life.
We cover London and the Home Counties, including Essex, Kent, Suffolk, Hertfordshire, Surrey, Berkshire, Oxfordshire, Hampshire, Buckinghamshire, Cambridgeshire, and Sussex. If you are unsure whether we cover your location, contact us and we will confirm availability.
