6 Signs That Your Boiler Is Broken

6 Signs That Your Boiler Is Broken

A boiler is one of those essential appliances like craftsman snowblower in households that are located in areas that experience cold climates most of the entire year. It is an important part of your central heating system that keeps your space and water warm — crucial during the winter season. However, boilers are so complicated that you need hours and hours of studying just to learn how to install, operate, and maintain it. Most of us don’t even know how it works. As a responsible homeowner, you should know when to tell that there is something wrong with your boiler system. With this, here are the signs that you should look out for that may indicate your boiler is not working properly.

Unpleasant smell

If you smell something weird around the house, it is time to check your boiler system. It is possible that the device has overheated and experienced a short circuit. The smell could also be caused by a gas leak since it’s what fuels your boiler. A rotten egg-like smell is a sign of a leak as gas suppliers add sulfur into the fluid to make future leaks easy to notice and detect.

Unusual sounds

As always, abnormal sounds coming from any device is not a good sign. Buzzing or whirring sounds can come from malfunctioning burners or fans. Contact your repairmen as soon as possible.


Puddles around your boiler may be caused by leaks coming from the device itself. Leaking water can be a sign of various internal problems of your boiler. Immediately have it checked by a technician. Replace the hose with something like zero g hose. Leaks may lead to more serious problems like mould growth and infestation caused by too much moisture.

Disperses less heat

If you notice that the room or the water is not as warm as it should be, check your boiler as there might be something wrong with the circulation.

Energy bills increased

A noticeable increase in your energy bill is also a sign that your boiler is not working properly. Old and malfunctioning boilers often consume more energy as their efficiency decrease overtime. If this happens, you may need to have it repaired by a professional technician or just replace it completely.

Not working at all

If your boiler stopped working completely, that’s a clear sign that there is something wrong with it. Have it checked immediately by a technician to avoid any further problem. Do not try to fix it on your own as it may complicate things.

You can avoid these problems by having your boiler inspected by a professional regularly. This will help. Especially during cold seasons, your device might be going on longer than usual. You want to avoid it from suddenly breaking down during the days that you extremely need it.

Repairs prolong the life of your boiler system, however, it does not prevent future costly damages. If your boiler is at least 10 years old and is constantly breaking down, you might need to finally replace it with an updated model. Modern heating systems, like Hydrogen ready combi boilers, are cost-effective and energy-efficient which make them convenient not only for your pocket but also for the environment.

If your boiler is broken or not working, the best thing to do is to get it examined and the problem diagnosed by a qualified and registered gas safe engineer. They will be able to efficiently examine the boiler and have it back up and running in no time at all. Bear in mind that if your boiler is over 10 years old, it’s unlikely it will be financially sensible to pay for it to be repaired since it’s likely no longer under warranty and break downs are highly likely to continue due to its age, costing more in the long run.

A brand new boiler can cost a substantial amount of money to buy upfront, but thankfully there are much pay monthly boiler schemes available, allowing you to spread the cost over many months or years so that it’s not such a financial burden.
