Top Boiler Problems & How You Can Deal with Them

Poorly maintained central heating systems can wreak havoc in your household during the winter months. It could be a disruption to your hot water supply or lack of heat due to inefficient central heating, but it can cause chaos. What if there was a way to predict these issues and prepare for such an event in advance? At Qualis, we’ve put together some common central heating and boiler-related issues and how you can deal with them.

·         Lack of heating from the boiler/ No/Loss of hot water

One central heating issue facing homeowners is a loss of hot water from the boiler. This is often due to a valve failure which is more common than you might think. Our tip - get it checked thoroughly by an expert engineer.

·         Water Leakage

Water leakage from boilers is common in the UK. To get to the root of the cause - find the source. Normally, this happens when an internal component of the boiler breaks, causing water to leak. Sometimes, wear and tear of the openings and joints can be the reason. Pressure valves can also cause leak issues if not maintained. To fix these issues, we recommend you get a boiler expert.

·         Noisy Boilers

When boilers get old, they often develop gurgling noises. Sometimes, central heating pumps develop blockages, and these can create unwanted noise.  Another common and alarming boiler sound (think explosion) usually happens when the boiler starts up. This is because of the trapped gas. The good part - it’s an easy fix – all it needs is to remove the airlock from the central heating pump. Best let the experts deal with it!

·         Boiler Pressure

You may have experienced your boiler starting to lose pressure. This could be due to a variety of reasons, such as: a possible leak, a broken valve, or inefficient radiators. To check the problem, you’ll need check the pressure gauge.  A reading of below 1, indicates low boiler pressure – indicating an ineffective central heating system within your home.

Our tip: Make it part of your winter routine to inspect your boiler pressure regularly to ensure best performance. Any reading like below 1 should cause alarm bells. Ideal pressure reading should be between 1 - 1.5.

·         Frozen Pipes

There is a condensate pipe in every boiler. Its primary role is to transport the acidic water, produced from waste gas, out of the boiler system. This pipe normally runs outside into a drain. Based on the location, it may freeze during winters. As a quick fix for such a problem, you can place a warm cloth, hot water bottle, or some heating pack on that frozen pipe. Pouring hot water can also work, if you do it correctly.

·         Radiators Not Heating Up

Radiators could not be heating because of the sludge or air that builds up in the system. You would notice that only the bottom of the radiator is heating. In such cases, you need to do bleeding of radiators. Sometimes, it may be because of the balancing issue. Then, you must ensure that the right amount of hot water reaches the radiator for even heat distribution. To fix the problem, you need to call a heating engineer. They have all the resources and are equipped with tools to clean the system and remove the sludge.

·         Thermostat Issues

Another common issue that households face is with the thermostat. Most of the time, you may need to replace it. But before doing that, check for common reasons like it should be on, and it should have the correct time and schedule setting. Buying a new one is a more reasonable option to fix the problem.

·         Kettling Issue

Kettling may occur due to Limescale buildup in the boiler or its piping. If you hear strange noises coming out of the pipe, such as whistling or gurgling, then it is a kettling issue. To solve the issue, you need to flush out the pipes to remove this build-up – best done by calling an engineer.

·         Heating is fine but hot water isn’t

As the boiler gets old, this problem becomes more common. The underlying issue is with the valve. It gets filled with sludge and dust. So, it directly impacts the hot water supply. It is advisable to invest in routine maintenance and service of the boiler to avoid such problems.

Always remember: A boiler is one of the most crucial appliances in the house. It’s always good to be aware of these issues. Make sure you regularly maintain the boiler and get your central heating system checked. While the small problems  such as bleeding your radiators can be handled yourself, some of the larger issues may require you to contact a certified boiler expert. If repair costs start mounting up, you’re often best looking at replacing it for a new boiler. It’s more efficient and can save you a lot of money in the long run.
