Does a Plumber Fix Boilers?
When your boiler stops working or starts acting up, your first thought might be to call a plumber. But is that the right move? Yes—many plumbers are qualified to repair, service, and install boilers, but not all are licensed to work on every type of system. In this article, the experts at Blue Boxer Plumbing break down the role of a plumber in boiler repair, when to call one, and what to expect during a service visit.
What Is a Boiler?
A boiler is a heating system that uses hot water or steam to warm your home. Unlike a furnace (which heats air), a boiler distributes heat through radiators or radiant floor systems. Boilers are common in older homes, multi-unit buildings, and regions where radiant heat is preferred.
Most boilers are powered by natural gas, propane, oil, or electricity and consist of multiple components, including burners, pumps, heat exchangers, valves, and thermostats.
So, Do Plumbers Fix Boilers?
Yes, plumbers often fix boilers—especially if the issue is related to water pressure, leaks, pipework, or valves. Boilers are part of your plumbing system because they involve water circulation. Here’s how a plumber typically helps with boilers:
- Diagnosing low pressure or no heat issues
- Fixing leaking pipes or valves connected to the boiler
- Replacing thermostats or zone valves
- Flushing sediment from the system
- Repairing circulator pumps or expansion tanks
However, depending on your location, working on the boiler’s fuel supply (gas, oil, or electric) may require a licensed heating contractor or HVAC technician with special certifications.
When Should You Call a Plumber for Boiler Issues?
You should call a plumber if you’re experiencing any of the following boiler-related problems:
- No hot water or heating from your boiler system
- Water leaks near the boiler or associated pipework
- Low water pressure in your boiler system
- Loud banging, gurgling, or whistling sounds (often caused by trapped air or sediment)
- Corroded pipes or fittings connected to the boiler
In these cases, a plumber with boiler experience—like the team at Blue Boxer Plumbing—can quickly diagnose and resolve the issue before it causes further damage.
When You Might Need an HVAC Technician or Boiler Specialist
If the issue is tied to the fuel source (like a gas burner not igniting, or problems with the control board), you may need to call in a certified HVAC technician or boiler specialist. Here are examples:
- Boiler won’t ignite or gas pilot light keeps going out
- Error codes related to internal sensors or electronics
- Problems with combustion or exhaust flue systems
- Annual tune-ups and safety inspections required by code
Some plumbing companies, like Blue Boxer Plumbing, may also have technicians licensed for both plumbing and HVAC work, making it easier to handle the entire system with one call.
