Important Boiler Terms

For homeowners, you don’t need to know the more advanced terms. If you do, just give us a call and we can help talk you through the specifics of your boiler system. Here are some important terms that relate to your boiler in very specific ways. You’ll want to have a solid grasp on all of these if you’re a boiler owner looking to have your system repaired by a pro.


The pressure of the water in your boiler is important. It can be measured in a variety of different ways, but it’s usually measured in PSI (pounds per square inch). Imagine squeezing a water balloon to fit a specific shape, this is your body applying pressure to the balloon so that it does what you want.

A boiler needs to keep water at an optimal pressure in order for it to heat your home properly. If pressure is too high, it could rupture or spring a leak. If the pressure is too low, you’ll have trouble feeling heat and there might be some rooms that don’t get warm enough.


The acidity level of your water is measured in standard pH. The more acidic your water, the more your boiler and pipes could start to corrode and fall apart. Water that’s high in acidity can chemically react to the minerals in your water and the lining of your pipes. It’s a good idea to get this checked and make sure your water isn’t acidic.


Scale refers to the mineral buildup in your boiler system. Similarly to limescale in your bathroom or kitchen, scale in your boiler can build up over time causing inefficiency to develop. There are various solutions available for homeowners that want to reduce the scale in their boiler and keep them running efficiently.
