A boiler that keeps losing pressure is one of the most common heating issues homeowners experience, especially during colder months. While topping up pressure can be a temporary fix, repeated drops often indicate an underlying problem.
In many Swindon homes, pressure loss is caused by small leaks in pipework, faulty pressure relief valves, or issues within the expansion vessel. Air trapped in radiators can also contribute, which is why bleeding radiators sometimes appears to “solve” the problem — although only briefly.
If your boiler regularly needs repressurising, it’s time to investigate properly. Continuing to run a boiler with unstable pressure can strain components and lead to costly breakdowns later. Our experienced engineers can diagnose faults quickly using our boiler breakdown and repair service.
Older systems may also benefit from a full system check or upgrade. If your boiler is inefficient or nearing the end of its lifespan, our home boiler installation services offer reliable, energy-efficient options.
For heating issues beyond the boiler itself, our central heating services cover radiators, pipework, and system balancing.
