Even though you might not think about your boiler all that much, it is a critical component of your home that needs to be taken care of on a regular basis. Just because it has lasted 20 years, that doesn't mean it is going to last another 20. While you might not want to spend money you don't need to, it is important to know when you need to act upon a boiler replacement and when it can wait. Consider the following factors when making a final decision on whether you should replace your boiler or not.
How much rust is lurking on the boiler?
The condition of your boiler is one of the main factors to consider when looking at whether to replace or repair it. While some boilers are used in a closed loop system where there is no water loss, others won't heat the same water more than once. Systems that are connected with a closed loop can end up getting destroyed because of a leak in the system that causes the minerals and oxygen to destroy the boiler. This tends to be the most common cause of failure in boilers. By paying attention to how much rust is building up on the system, you can determine how bad it is getting before it spirals out of control.
Is there a bunch of water leaking around the unit?
While some leaks are quite obvious, others take a little investigative work to identify. When the pipes are underground, it makes it quite difficult to determine whether there is a leak in the system or not. A return line that is covered in cement and dirt tends to end up wearing out far quicker than lines that aren't buried. Any piping that runs underground should be replaced with piping above ground to prevent leaks from occurring.
Are there replacement parts available?
Consider whether you are going to be able to find replacement parts for your boiler or not. If you have a burner that needs to be replaced, you don't want to be stuck with a non-working unit all because you cannot get the parts any longer. While it might make logical sense to repair your existing unit, that isn't always a feasible option. An old unit can also cause more pollution and be less efficient than the newer ones.
Take the time to have your existing boiler inspected to determine what steps you should take to get your unit back up and working properly. In many cases, boiler repairs are a viable option, so talk to a professional to find out what they'd recommend.
