5 Signs It’s Time For Boiler Repair

Boilers are an important part of any home because they provide clean, safe, and hot water for a variety of purposes: washing, cooking, and general cleaning. However, if problems do start occurring, then it’s imperative that you take immediate action. This way, you can address the root cause of the issue before it starts branching out to other symptoms.

This is supposed to be your boiler, but suddenly it’s making incredibly loud whistling noises—much like the sound of a boiling kettle. Kettling may be caused by a buildup of sludge and limescale, which restricts the flow of water throughout the system. 

Hard water, which has a surplus of the minerals leading to kettling, is a common issue in many areas, so it’s important to be proactive about the state of your boiler. If left unattended to, kettling boilers are more likely to face further issues, like leaks.

Drips and Leaks

If you have a leak that is coming directly from the boiler tank, then don’t bother trying to solve the problem yourself. It’s far too dangerous. This leak is an indication that the boiler has started corroding through and will require replacement. 

However, it is possible that the leaks are from a pump or a pressure relief valve, which are parts that can easily be repaired or replaced. 

Pilot Issues

The pilot light is a part of the boiler system that is responsible for igniting the gas inside the boiler. This is what allows the equipment to heat up your home and deliver warm water to your taps. If everything is going well, all you need to do is light up the pilot light and leave it running throughout the day. However, it’s possible for your boiler to start having problems with the thermocouple. This leads to the burners failing to ignite—and as a result, your water remains unheated. 

Low Boiler Pressure

Is your boiler leaking or turning off at the most unexpected times? In these situations, it is possible that the problem is caused by low boiler pressure. You may also need to get your expansion vessel checked. 

Luckily, each boiler has a manual that details the steps you need to take to re-pressurize your boiler. While these instructions are optimized for the end user, you may not always have the time or energy to take on these tasks by yourself. In this case, it is best to consult a reliable boiler repair man and have them do the job for you instead.

Lack of Heat

This problem can be caused by a multitude of issues. You will definitely need a professional to take a look at what has happened to your boiler. Some problems include issues with the safety switch, a broken pump, or a faulty thermostat.

A buildup of air and rust in the pipes may also be preventing the system from warming the house as needed.
