In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I just finished my basement and closed off my steam boiler WM EG-45 & a 40 gal water heater from the rest of the basement with a 36" bifold door.
The room is approximately 10 x 6. The room does get rather warm during boiler operation, but I am most concerned about not having enough combustion air.
The space does have a basement window and the room is not air tight, I also have also added a vent to the rest of the basement with a standard AC return vent.
Would poking a hole through the sill and adding fresh air intake, be a good idea and provide sufficient air for the boiler?
Are special vents available for this purpose, and where can I purchase?
