Oil Boiler Repair & Service

Common reasons for oil boiler repair

• No Heat: If your boiler isn’t producing heat and boiling the water, then there are a couple of possible problems. Often, this is simply due to a broken thermostat, but if this isn't the problem, the issue is likely a broken diaphragm, airlock, or valve.

• Leaking: Leaks can have a variety of causes depending on where they occur. Leaks around the pipe or tank often indicate corrosion and leaks from the pressure valve tend to indicate that the pressure is too high. If the leak is around the pump seal, then a broken pump seal is likely the culprit and will need to be replaced. Wherever the leak, you should always have a professional take a look to properly diagnose the problem and make the required boiler repairs.

• Kettling: If you’re hearing a loud hissing and rumbling noise, like a boiling kettle, coming from your boiler, you likely have lime scale or sludge building up in the heat exchanger. This restricts the flow of water, leading to overheating which causes the aforementioned sound. This can happen to any home, but is most likely if you have hard water. If you hear this sound, contact your local contractor to take a look and flush the system.

• Low Pressure: Boilers require a certain amount of pressure to operate, but luckily checking the pressure is as easy as looking at the built-in pressure gauge. If you notice the pressure is at 1.0 or below, your boiler has low pressure. This could be due to a leak, a recently bled radiator, or even just a broken pressure gauge. In the latter case your system may work fine, but you should have the gauge replaced.
