There’s nothing more aggravating than having your boiler break down. It’s likely that it broke down during a cold spell, leaving you with days of cold showers and a frigid home until you can find an expert to fix it.

Your boiler’s handbook should be your first point of contact if you’re trying to figure out what’s wrong. It’s a wealth of information that explains trouble codes and tells you whether or not you can fix the problem yourself. Most manufacturers will let you download a copy of your manual if you can’t find it.

The most prevalent boiler issues

The majority of serious boiler defects are difficult to diagnose for a layperson, and you should never try any repairs that require removing the boiler casing if you are not a trained heating professional. It’s not only unsafe, but it also voids any guarantee you may have on the boiler.

Two of the three most common boiler failures, on the other hand, can be addressed by a capable DIYer and don’t always necessitate the services of a pricey heating professional.

The condensate pipe of a boiler has frozen

When the weather turns cold, a frozen condensate line (a condensate pipe is a component of condensing boilers) can knock your boiler out of commission. Although it isn’t technically an issue with the boiler, if the condensate line freezes, it will cause the boiler to shut down for safety reasons.

Always double-check that the condensate pipe isn’t the source of the problem before calling an engineer for an expensive call-out fee. In our advice on how to thaw a frozen boiler condensate line, we show you how to do so safely.

Make sure your condensate is adequately insulated with foam, as shown in the image above, to avoid it from freezing in the first place.

The pressure in the boiler is dropping

One of a few factors could be causing your boiler to lose pressure. However, it’s most likely a leak, you’ve recently bled your radiators and the system has lost pressure, or your heating has been turned off for an extended period of time and has lost pressure.

You can repressurize your system by opening the boiler’s filling loop taps until you reach the desired pressure (usually around 1 bar). Remember to close both taps when you’re finished, and your boiler should start working again.

If your boiler is frequently losing pressure, you should get it inspected by a skilled engineer to fix that the problem is permanently resolved.

The boiler is leaking water

This is frequently caused by rusted and old washers. To open up the boiler and replace the parts, you’ll need a qualified heating professional.

Boiler failures are extremely dangerous

Carbon monoxide continues to kill between 25 and 50 people in Dublin every year. According to the Carbon Monoxide and Gas Safety Society, central heating boilers are the leading cause of this tragic statistic.

CO is a colorless, odourless gas created when carbon-based fuels, such as gas, are burned incompletely. CO can kill rapidly because it hinders the circulation from transporting oxygen across the body. Headaches, dyspnea, nausea, dizziness, loss of consciousness, sleepiness, vomiting, chest pains, stomach pains, or visual issues are some of the symptoms.
