If you want your boiler to be in the best condition for use during winter, service it during the summer. If, however, you are unable to perform regular maintenance services in the summer, there are a few causes of breakdown to look out for. They include the following;

Inaccurate Thermostats

If the thermostat of your boiler is inaccurate, it may lead to a breakdown. It may not produce enough heat to keep you comfortable. If you use your boiler for a long time, the thermostat may lose its accuracy. You need the help of a boiler engineer o get it fixed.

Loss of Pressure

Loss of pressure can cause leakage and other problems on your boiler. It may also be a sign that your pressure release valve needs to be replaced. In case of loss of pressure, our first move should be to check your pipes for signs of leakage. Do not attempt to resolve the problem on your own. Get the help of a professional instead.

Pilot light goes out

Your boiler’s pilot light needs to stay on. If it goes out, your boiler may be unable to generate hot water. If your boiler is an older model, it is heavily dependent on the pilot light Ask your boiler engineer to help you with the problem before it gets out of hand.

Boiler keeps switching off

If your boiler randomly switches itself off, it is an indication that something is wrong and you need to get it repaired as soon as possible. It may be a sign that your condensate pipe is frozen. If you do not deal with the problem instantly, it may lead to a breakdown.

Strange Noises

If your boiler is suddenly producing unusual sounds, it is a sign that there is a problem. It may be caused by low pressure or leaks. You should check for leaks and get the help of a boiler engineer as soon as possible.

Radiators Not Heating Up

If your radiators are not heating up, they may be a sign of a problem. It is usually a sign that there is too much sludge in your system. If only your bottom radiator is heating up, consider bleeding the radiator. If some radiators are heating up and others are not, you probably need balancing. Other procedures are fairly simple and you can do them on your own. If however, you are not comfortable, get the help of an engineer.

Spotting the Most Common Commercial Boiler Problems

Commercial boilers are extremely advanced heating systems and yet, issues can still occur from time to time. In order to know when you may require the assistance of commercial gas services, it is a good idea to highlight a handful of common problems.

Low System Pressure

Commercial boilers are not able to function properly if the internal pressure is too low. This could be caused by a leak within the system or as the result of a faulty valve. If no visible leak can be detected or if there is no apparent damage, it is best to consult with a professional.

A Lack of Heat

There can be times when you notice that a specific portion of the boiler is not heating up properly. Often referred to as “cold patches”, this situation can result from an accumulation of sludge within the system or air that should not be present. There may be times when “bleeding” the unit will resolve the issue. If this does not help, the chances are that the issue is found within the lower portion of the tank. Once again, it is important to consult with commercial gas services in order to correctly diagnose the issue.

Strange Noises

Boilers can sometimes emit strange sounds such as gurgling or bubbling. Broken pumps or air that has become trapped within the circulation system are two common causes. These might be nothing serious or they could signal a more advanced problem such as an accumulation of limescale (mineral deposits from water). As these noises will normally not go away on their own, it is prudent to consult with an expert.

An Intermittent Pilot Light

Pilot lights should always remain lit. If you notice that one has gone out, there could be an issue with the gas supply to your boiler. This might signal that a part known as a thermocouple needs to be replaced. It can sometimes be difficult to reignite this flame and if other gas-supplied appliances are not functioning, call a specialist as soon as possible. He or she will be able to determine if the problem is within the boiler or if additional steps need to be taken.

If you got your boiler ten or more years ago, you should probably get a new one. Older models are susceptible to breakdowns and they do not run efficiently. Failure to get a replacement may cause you to spend more money than you need to. Boiler breakdowns in Manchester are a common problem but fortunately, it is possible to find a solution.
