Condensation on inside of windows

Hello, I had a new boiler installed a couple of months ago in my house and ever since I have noticed quite alot of condensation on my windows. I know that I do need to install a bathroom fan. On my old 1950's boiler I didn't see this problem. Is it because the new boiler is so efficient? I didn't notice anywhere to adjust or turn off humidity level on the boiler. When I do get around to installing a bathroom fan, will this totally resolve this problem or should I purchase a de-humidifier. I used to have to use a humidifier until the new boiler was installed. I live in Alberta Canada where it gets pretty cold. Thanks again for all your advice. It's nice to know there is a helping hand out there. I love you guys!!!

Most new boilers have a way to turn down the humidity.If you can't see it , read your book or call the people who installed it and ask them to tell you how to turn it down.

I just ran across this last week ( only the people thought the window was leaking )

The answer depends upon what type of heating system you have.

If you have a hot water baseboard system, there is no way to adjust the humidity.

If your boiler creates steam for a radiator system, the new boiler may be producing more steam with the steam releasing into the home as part of the vent system.

You can control excess humidity with a de-humidifier, but adjustments to the boiler will unlikely solve your problem.

Pick up a hygrometer where they sell thermometers. Humidity should be maintained between 35-55%. If over 55%, you need to dehumidify. Humidity will tend to vary from room to room.
