Although gas heating systems are generally considered to be reliable, there are a few common ways in which they can break down, some of which are dangerous. Read on to learn how to identify when your home's gas heating system is malfunctioning so you can take action to repair the system and keep yourself and your family safe.

1. Gas Leaks

No gas can escape from a well-functioning gas heating system, but one that is malfunctioning can allow gas to leak out. Natural gas is highly flammable, so it is important to recognise a gas leak as quickly as possible and call an engineer to deal with the problem.

Natural gas typically has a sulphurous smell added to it, which is similar to the smell of an egg that has gone bad. If you smell this unpleasant odour in your home, turn off the gas right away, open as many doors and windows as possible to ventilate your home, and contact a gas engineer. While you wait for the gas service to arrive, do not smoke or light any matches or candles to avoid the risk of a gas explosion.

2. Carbon Monoxide Production

Gas heating systems are designed to burn natural gas in a process that produces carbon dioxide and water. However, if not enough oxygen is present in the furnace, the gas can burn in a process known as incomplete combustion, which produces a toxic gas called carbon monoxide.

Signs of carbon monoxide poisoning include tiredness, flushed skin, headaches, dizziness, and shortness of breath. Without treatment, it can be fatal. If you suspect you have carbon monoxide poisoning, it is important to seek healthcare as soon as possible.

All homes that use gas heating should have a carbon monoxide detector. If your detector suggests that carbon monoxide is present in your home, turn off the gas heating, open windows to let in some fresh air, and contact a gas heating repair service.

3. Inefficient Combustion

Sometimes, gas heating systems malfunction in ways that are not dangerous to your health but that can put a strain on your household budget. Furnaces that are poorly maintained can become very inefficient, leading to your household spending much more money on gas.

If you notice your energy bills creeping up, contact a gas heating repair service. They can assess your gas furnace to work out why it is not burning as efficiently as it once did and give you an estimate for the cost of repair.
