Boiler Repair questions, answered by experts

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

Once you know where your bleed valves are and how to use them, bleeding out heaters is a quick process. Expect it to take around 10 to 20 minutes, possibly longer if you have a lot of heaters or are still learning how they work. If you have a central bleed valve on your boiler, the process still takes the same amount of time. Make sure you have any keys necessary to turn the bleed valves on. Without bleed valves, the process should take around three hours.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Leaks, pressure loss, air in the system, burner failures, and thermostat malfunctions are common problems that require professional repair.
