    Boiler room with radiant heat very hot

    Hi, I have a question concerning my small mechanical room that house my propane fed boiler, hot water heater, and a bunch of copper piping leading out to the radiant heating system in the house.
    In the winter this space gets VERY hot because of all the copper piping carrying the hot water to the radiant system. I have insulated the pipe as best I can, but it still gets really warm.
    This mechanical room is on the same floor as a living area.
    What I'm wondering is if it would be OK to run a vent out into the living area to take advantage of the wasted heat in the mechanical room. The boiler is direct vent out the side wall if that makes a difference.
    I was thinking I could put a small fan assisted vent by the ceiling and pipe it out, along with a vent in the wall down low to allow for replacement air to come in.
    My biggest concern would be any Carbon Monoxide or any other gasses that may the result of propane combustion.

    Advice?

    Thanks.

    You should

    consult a contractor to look at this for you. We cannot give DIY advice, and we cannot see your setup online.

    Not sure a contractor will want to come out to put in a $20 fan but I'll give it a shot.
    The house if in VT, and it's tough to get anyone to come to your home for such a small job.

    What about your hot water heater is it direct vent?

    A $__ fan will not be an $__ fan if a contractor installs it... Its only a $__ fan if you install it...

    Consider that any fuel burning appliance has the potential to create carbon monoxide.

    Now consider that you want to install a fan to force that lovely gas right into your living space.

    I would be very cautious and very hesitant about doing so. Fuel burning appliances are quite sensitive to proper fuel-air mixture and proper venting.

    Installing your fan would likely alter all of these items.

    Not worth a few bucks in heat, IMO.

    Both pieces of equipment are sealed combustion and piped out doors.

    I wouldn't do a fan system. Your life of you and your family are worth more than that.

    The only way I would try re-capture the energy is via a little run around coil so there is no chance of co poisoning via air flow. You would need a pro!

    Is there any place for that heat to go BESIDES your living spaces? Odds are, the heat is already migrating out to your living areas, so any forced movement isn't really going to change anything. Certainly not worth the risk of pulling the exhaust into the living spaces.
