Toilets, Sinks, Showers, Tubs and Disposals - Low Hot Water Pressure

I've done a search on this but didn't really come up with an answer. My kitchen and bathrooom sinks, as well as my shower all have low hot water pressure. Temperature is fine and what pressure i have stays constant. It's been this way since we moved in. I'm not sure if we have a water softener. The water from outside looks like it goes through a large blue cylindrical container about four feet in height. It doesn't look like there's anything you can do with it. From there, the water goes into our hot water boiler to make our hot water and to supply the hot water for our baseboard heating. That's about all i can think of. I checked to make sure all of the valves are open completely and they are.

Help,

Is the low water pressure on the hot water side only, or both?
If it's on both the hot and cold, the sink aerators and showerhead may just be clogged with minerals or line debris. Remove them to clean them out, and try the water pressure to see if that's it.
If it's on the hot water side only, it could be mineral buildup in the boiler coils, which would require the coil to be removed and professionally cleaned out (like radiator shops do radiators) or replaced.
Good luck!

It's definitely the hot water side only. We've been talking about getting the boiler serviced so maybe we should mention that when we schedule an appointment. I do have a well. Is this buildup a common problem?

Yep. Over time, it happens to all boiler coils with hard water running through them sooner or later (usually calcium and magnesium buildup).
