Sooner is cheaper for pressure loss and kettling too — both get worse and both damage other components. ### Repair or replace? We'll tell you honestly. If the part is available, the boiler is under about 12 years old and the repair is a sensible fraction of a replacement, repairing is usually the right call. If it's an obsolete PCB on a fifteen-year-old unit that has already failed twice this winter, we'll say so rather than sell you a repair that buys three months. What happens if it's ignored ## The cost of waiting. Boiler faults rarely stay single faults. One failing component drags others with it, and the repair bill grows with every reset. ### Common mistakes we see - Over-pressurising the system with the filling loop instead of finding the leak. - Replacing a PCB before checking the sensors and wiring feeding it. - Ignoring a frozen condensate pipe and calling it a boiler fault. - Fitting parts without cleaning the system, so the new pump or valve fails the same way. - Resetting a lock-out repeatedly rather than reading the fault history. ### Repeated pressure loss means a leak somewhere Topping up the filling loop every week isn't a fix. Water is going somewhere — a pipe joint, a radiator, the pressure relief valve or a failing expansion vessel — and the constant fresh water introduces oxygen that corrodes the system from inside. ### Kettling damages the heat exchanger Banging and rumbling means scale or sludge is causing localised boiling inside the heat exchanger. Left alone, it turns a cleanse into a heat exchanger replacement. ### Repeated resets hide a safety fault Lock-outs are protection, not an inconvenience. Repeatedly resetting a boiler that keeps failing on flame or overheat is exactly the pattern that ends with a dangerous appliance. ### Cold property damage An unheated house in a Coventry winter risks frozen and burst pipework, which costs far more than the original repair. Our process ## A clear, documented system — every visit, every job. 1. 01 ### 1\. Triage on the phone A few questions and the fault code often tell us whether it's an emergency, whether you can safely restore heat yourself, and what parts to bring. 2. 02 ### 2\. On-site diagnosis Fault history read, gas pressure and combustion checked, components tested electrically — we find the cause before we quote a part. 3. 03 ### 3\. Estimate before the repair You get the cost of parts and labour, plus an honest view on whether repair or replacement makes better sense. 4. 04 ### 4\. Repair and test Parts fitted, system re-pressurised and purged, gas rate and combustion re-checked, and the boiler run through a full cycle before we leave. 5. 05 ### 5\. Prevention advice We tell you what caused it — filter, inhibitor, cleanse or a service interval — so it doesn't happen again. Benefits ## What you actually get. ### Fast response Open 24/7, with emergency attendance in Coventry typically within one to two hours. ### Real diagnosis Fault history and live testing rather than parts-swapping guesswork. ### Estimate first You approve the cost before we fit anything. ### All makes worked on Combi, system and conventional gas boilers across the common UK brands. ### Landlord-ready records Written record of the fault and the work carried out for your property file. ### 1-year workmanship guarantee Our repair work is guaranteed in writing. In depth ## Materials, methods and variations. Most boiler call-outs across Coventry fall into a handful of repeatable patterns. Knowing them is what turns a two-hour diagnosis into a twenty-minute one. [Discuss your project](/contact) ### No heating and no hot water Usually electrical supply, a lock-out, a failed pump, an airlocked system or a seized diverter. We check power and fault codes first, then pump operation and system pressure, then the gas side with a manometer before condemning any component. ### Hot water but no heating (or the reverse) Classic diverter valve territory on a combi — either the valve head has failed or the valve body is sticking with sludge. On a system boiler it more often points to a motorised valve, cylinder stat or wiring centre fault. ### Losing pressure We pressure-test and trace: visible joints, radiator valves and tails, the pressure relief valve discharge outside (a dripping discharge pipe is the giveaway), and the expansion vessel charge. Recharging or replacing a flat expansion vessel resolves a large share of these. ### Fault codes and lock-outs Ignition lock-outs point to gas supply, electrode, spark lead or fan and pressure switch. Overheat lock-outs point to flow restriction — sludge, a closed valve, a failing pump or a scaled heat exchanger. The code narrows it; the testing confirms it. ### Frozen condensate and winter faults A boiler that fails on the first hard frost and shows a condensate or ignition-related code is usually a frozen external condensate run. We thaw and clear it, then re-route, upsize or insulate the pipe so the same freeze doesn't repeat every January. ### Noise: kettling, banging and whistling Kettling is scale or sludge causing local boiling. Depending on severity we descale, cleanse or power flush, fit a magnetic filter and inhibitor, and re-balance. Where the exchanger is already damaged we'll say so honestly rather than flushing a lost cause.
