Boiler Repair questions, answered by experts

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.

It is almost always more affordable to repair a radiator than it is to replace one. The average radiator repair cost is around $150, and it’s typically about ten times as expensive—around $1,500—to replace a radiator. A repair usually takes under an hour, too, while a replacement can take several hours, making it less of a time commitment to repair one.

Although boilers can last 15 to 20 years when maintained properly, you may run into some common problems like oil burners and transformers malfunctioning; cracks in the heat exchanger; clogs in the heating oil pump, burner nozzles, or fuel pipes; loose wiring connections; and damaged valves. Many of these problems can be caught early on during annual maintenance services. You might also have an issue with your fuel source if you have a gas or oil boiler. Make sure your other gas appliances are working or that you have oil in your tank.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
