10 Tips for Effective Boiler Maintenance


What is a boiler and how does it work?

The boiler is one of the most fundamental devices in every house, providing people with hot water during the year and warm rooms in the cold time of the year. It is of high importance to make sure your boiler functions well. This is possible if you know what a boiler is, its operation, and some tips to keep it in tip-top condition and make your boiler work effectively for several years. One of the key factors to consider is boiler maintenance.
If we want to say what a boiler does in easy words, we can say it heats the water and sends it to the radiator to make your house feel comfy in the cold months of the year. It also provides you with the hot water you need during the year. So, its function is to heat your house and bring hot water to your faucets.
But how does this happen? Every boiler uses a kind of fuel to heat the water. The fuel, which in many cases is the gas, enters the boiler through a valve connected to the fuel supply. As it enters the combustion chamber, a spark lights fire. That will heat the water, and later the hot water is pumped to the pipes when you turn on your radiator system or open a faucet.

How to maintain the boiler in tip top condition?

There are a few simple but essential tips to help you use your boiler for a long time effectively.

2. Bleed the radiator
