How to Recognize Boiler Problems

If you know how to recognize boiler problems, you can identify them early and possibly avoid more costly repairs. Your heating system is one of the most important appliances in your home. It is also one of the most expensive to buy and to repair. Hence, you want it to last a long time. And it will – provided that you use it with care and maintain it properly. Aside from getting an annual boiler service done, you can help prolong the life of your boiler by learning how to recognize boiler problems. If you know how to tell if your boiler is not functioning properly, you can provide a quick fix right away or call an engineer sooner rather than later. Letting a broken boiler sit without getting fixed and ignoring that it needs repair will only cost you more. That small problem will only get bigger and your boiler will perform poorly and slowly deteriorate. What may have been a need for a little tuning on the thermostat or pressure gauge can turn into a need to replace parts or even the entire boiler if the problem is ignored. How to recognize boiler problems Here are five signs that your boiler is not working okay: There is no heat or no hot water (or both) – Perhaps this is the biggest sign that your boiler is having a problem, and it’s hard to miss. If your boiler is not heating, it does not always mean that is broken. This may be solved by doing simple DIY troubleshooting, such as simply checking your thermostat. The flame in the...

Gas Boiler Banging

Listening to your gas boiler banging can be annoying – and concerning. And you have every right to be both annoyed and concerned. A noisy boiler should be addressed right away. Ignoring this common problem may lead to more costly repairs in the future. Gas Boiler Banging – What’s the culprit? The most common culprit here is scale build up. Water contains minerals, and over time, those minerals accumulate at the bottom of the boiler tank, causing hot spots. The water boils rapidly and sends bubbles up the tank. The bubbles then dissipate violently when they reach the top of the tank, producing loud, banging noises. A noisy boiler is also known as “kettling”, as the limescale blocks water flow and causes the water to boil, steam and expand, just like boiling water in a kettle. This is not something that you should fix on your own. Only a gas safe registered engineer should handle the problem. Gas Boiler Banging – Other causes There are a few other things that may be causing boiler noise. Water temperature: If the water gets too hot, it can cause similar rapid boiling in the tank, sending bubbles of water to the top of the tank. Lowering the boiler thermostat can solve this problem, although this will also make your home less warm. Check if your thermostat is defective and needs replacing. You can learn how to calibrate a thermostat too. Low pressure: If the boiler pressure is too low, the boiler will not get enough water supply. With not enough water supply, the heat will not dissipate fast enough and will cause the water to boil. You...

Boiler Has No Heat But Has Hot Water

A boiler that has no heat but is producing hot water can cause a lot of frustration, especially if it happens during the winter months. Both the ideas of having a central heating that is not working and that you have no hot water are not appealing. Your initial reaction is probably to panic as you think about the worst case scenarios. Will you have no heat for the entire week? Or maybe you’ll need to do a boiler replacement? Relax. While you might need to get a boiler repair scheduled, you can also take a few steps to see if you can get your boiler running again.   No Heat If your boiler is not keeping your home warm, try the following: Check the thermostat. It is easy to overlook the temperature set on your thermostat. Sometimes, the settings may have been altered during cleaning or dusting. Rule this out by making sure the temperature is set correctly. Set the temperature above the current room temperature and make sure that the setting is set to Heat or Auto. You can also try to get the boiler to work by placing the thermostat to the highest setting. Check the power source. This is another thing that is commonly missed and overlooked. Remember that even if your boiler runs on gas or oil, it is still connected to an electricity source to run. Make sure that the boiler is plugged in properly and that the breaker is not tripped. Check the fuel source. Remember to also check your gas connection and make sure it is on and you have gas supply. Check the...

Combi Boiler Repair

Any combi boiler repair must be done by a gas safe registered engineer. In the UK, about 50% of boiler installations are combi boilers. This is mainly because combi boilers are typically more efficient and convenient than the more traditional water tank. However, they are also more complicated, and can be a real pain when they breakdown. A number of minor problems that you will encounter can be fixed by the regular DIY- er. A DIY boiler fix is never recommended for a major combi boiler repair. Here are some of the common boiler problems you may encounter: boiler leaking water pilot light keeps turning off boiler loosing pressure boiler pressure too high boiler not heating water gurgling in boiler noisy boiler radiators not heating central heating not working no hot water Here are some basic tips when doing a combi boiler repair yourself: Always start with the electric and gas supply. Make sure that the boiler is plugged in and connected properly. As silly as this may sound, this step is also often overlooked. Start by checking the power supplies, and you might save yourself lots of time and money. Check the thermostat. The temperature setting may have been changed or altered. Check the pressure gauge and make sure it is set correctly. You can learn how to increase the boiler pressure using our guidelines. Learn the easy steps on how to bleed the radiators. In case of a frozen condensate pipe, carefully thaw the pipe using proper precautions. Learn how here. Remember to always read the owner’s manual before starting any combi boiler repair.

Boiler Fix

Do you need to do a boiler fix? It is always best to call for a trained engineer to fix any boiler problems. However, a DIY homeowner can diagnose the issue and do a boiler fix for minor problems. This will actually help you cut your costs, and even make the job faster for the engineer, if you eventually schedule one. Easy Boiler Fix Boiler radiators are not heating: CAUSE: Radiators that are cold at the top show that there is air trapped in the system, rusty pipes, or problem with the pump. SOLUTION: You can remove trapped air by bleeding the radiators. You can do this job yourself. Here’s how. If that does not fix the problem, a power flush may be needed. Here’s how to power flush. Boiler turns off: CAUSE: This problem can be caused by a number of reasons including low water pressure, thermostat problems, a frozen condensate pipe, air trapped in the system or a pump problem. SOLUTION: We already know that you have to bleed the radiators in case air is trapped in the system. If your pipes freeze during cold months, you can thaw them yourself. Learn how to thaw a frozen condensate pipe. You can also learn how to repressurize your boiler  if you see that the pressure is incorrect. Replacing the pump must be done by a qualified engineer. Pilot light keeps turning off CAUSE: Either the thermocouple is not working properly, or there are damages to the seal. SOLUTION: Both of these types of work must only be completed by a qualified engineer. Learn more about how the pilot light works....
