Replace Your Boiler

Boilers aren’t perfect. They will eventually be out of service and, when this happens, you will need to buy a new one. But, how do you know when it’s time to replace your boiler? A few breakdowns and damages will tell you that it needs to be replaced. This blog will be about How Can You Tell It’s Time To Replace Your Boiler.

Here is a list of things you have to know when it’s time to buy a new boiler.

10 Signs That You Need a New Boiler

#1: Boilers don’t heat up as much.

A boilers’ primary function is to heat water and turn it into gas to increase the temperature of your house. However, when boilers take hours to heat up, it usually means that they’re deteriorating. When it usually takes a boiler to heat up as quickly as a few minutes after it’s switched on. 


Slow heating doesn’t always mean that the boiler is broken or old. Sometimes, it might be because of an air blockage or a cold spot. Professionals can take action, but you need to buy a new one if the repair costs are too high.

#2: The boiler smells.

A new and well-functioning boiler is odorless, so when you smell a weird scent coming off your boiler, it could mean that it’s broken. The smell results from carbon monoxide leaking from the radiator, which means the boiler is not burning correctly inside. 


Or it could also indicate parts getting burnt. Since there is gas involved in the boiler, there’s a massive chance of burning, so take note of the smell.

#3: The boiler turns off on its own.

When boilers keep shutting down, you have to get a new boiler. Your boiler could be shutting off frequently due to damage in the boiler – with the pump or some other parts. If you can replace some parts, do it. But in the worst case, it can’t be repaired anymore, then just purchase a new boiler.

#4: Decrease in pressure. 

When the pressure has decreased, it could mean that the valve is broken or damaged. In this case, it’s time to buy a new boiler. Having a broken or damaged valve can lead to an accident with the boiler. Therefore, it’s better to purchase a new one rather than risk being in an accident.

#5: Boiler keeps making weird noises

When your boiler has these clanking or whirring noises, you should be alarmed. Healthy boilers make a humming noise when turned on; sometimes, you can’t even hear it. So when you hear unusual sounds coming off of it, it could mean that it’s not in tiptop shape anymore and need replacement.

#6: Kettling noises.

Kettling is the noise when sludge surrounds the heat exchanger. Obstruction to the water flow will make deposits, commonly from hard water, build up in the heat exchanger causing the kettling noise.

#7: Flame is yellow.

When the flame is green, it means the boiler is healthy. However, if the flame turns yellow, it could indicate carbon monoxide leakage. Although carbon monoxide is odourless and colourless, the leakage process may have changed the colour of the flame.

#8: Repeated breakdowns. 

When your boiler keeps breaking down, then it’s time to buy a new one. If you’re looking to find a new boiler to replace your existing one, you can easily get a boiler quote online and have it replaced without causing too much of a hassle on your part.

#9: Energy bills are increasing. 

Increasing energy bills is a result of inefficient boilers. You can check a boiler’s efficiency by looking at its ERP energy rating. If your boiler is G-rated, then you have to replace it with a new one that is A-rated.

#10: Production for boiler parts has ceased. 

Some parts of the boiler might not be manufactured anymore. In this case, buying a new one is the best option for you. 

Boilers will eventually stop working, so take note of these indicators and decide whether a replacement is in order.
