Home Boiler Maintenance

Certain equipment in your home may feel intimidating if you don’t interact with it much. You expect your boiler to heat your home throughout the colder months. When it fails, temperatures can become too cold to bear. Knowing the signs of possible disrepair can help you keep your boiler in good working order.

Deposit Buildup and Corrosion

Corrosion can cause your boiler to break down and deteriorate after long stretches of exposure. It’s caused by lime-scale buildup and the presence of oxygen in the water supply. In most boilers, deaerator pumps take care of this oxygen, as well as other gasses, to keep rust from forming.

Descaling is a regular maintenance procedure, but it’s also a good idea to look at what’s causing excessive accumulation inside your unit. You can address the problem and prevent it from recurring.


Leaks in your boiler are more than just a nuisance. If water is pooling around the bottom, it suggests a major issue inside the unit. Damage to the hull can produce cracks that let water seep through. An old boiler is more likely to incur deterioration that results in leaking. As a general rule, this piece of equipment should be replaced every 15 years or so.

Water Deficiency

A boiler that runs on a deficient amount of water can be a potentially dangerous situation. If the problem persists long enough, you may have no choice but to replace the boiler entirely. It’s a good idea to test the water level every couple of weeks to make sure it’s still where it should be. This issue can be compounded if your unit is also leaking.

Keeping up with boiler maintenance is key if you want to preserve a comfortable and safe environment in your home. When the time comes, you should switch out the necessary parts or replace the entire unit.
