We often only hear the terms “boiler” or “boiler room” in horror stories or superhero flicks. The average person might not even know what a boiler is, aside from that little drawer in their stove (which is, incidentally, called a broiler, not a boiler). They might not even know if their home has one!


Fortunately, boilers are amazing at heating many modern homes; unfortunately, public knowledge about them is, as seen above, lacking. P&D Mechanical, a Robbinsdale expert in everything from boiler replacement to toilet repair, gives a rundown of some boiler basics below.

What is a Boiler?

A boiler uses warm water to heat your home (as opposed to a furnace, which uses warm air). The water is pumped through water piping and radiators and eventually returns to the boiler to be heated again. Thermostats, aquastats (devices that control the boiler’s water temperature and how often it fires), are all integral parts of your home’s boiler system and must be checked periodically, lest they need maintenance. Appearance-wise, your boiler can resemble anything from a robotic-looking blue box to a solid metal canister.


Boilers are cited for their relative silence and even heating capabilities when compared to furnaces. Certain types of radiant floor heating are also only installable in households with boilers.

How to Know When it’s Time for Boiler Replacement

●        Water leakage. Water leaking or spurting from your boiler is an obvious sign something is wrong. Never try to repair this yourself! The problem often lies inside of the boiler and is a job for a professional.

●        Your boiler is old. Older boilers tend to up to 20 years, while the newer condensing models are expected to last around 15 years. If your boiler is getting up there in age, don’t wait for it to fail before you replace it, especially with winter right around the corner.

●        Your energy bills are increasing. Of course, there are bound to be fluctuations in your bills as the seasons change. However, if you’re paying an unusually high amount for this time of year, your boiler could be the culprit. Just make sure other parts of your home, such as your water piping or radiant floor heating, aren’t to blame first.
