Boiler recommendation for difficult location

Check with the manufacturer's tech support to see if they would void warranty for venting the way you want to. The only things I can see against it are that condensate would be dripping out the open end of the pipe onto the ground, but that might not be a problem to you. Also, you would need to attend to preventing it from getting blocked and it should not blow out on plants you would like to keep. i.ve done this in the past with perfectly good results.

    Boiler recommendation for difficult location

    We are replacing a boiler/water heater currently located in our laundry room and would like to relocate the new system to our garage. We like the Buderus GB 142 wall hung boiler but it would have to vent through the front of our house. We are concerned about the esthetics but also that the place where the pipes would exit the house is by a walkway so that whoever walks past will get a cloud of water vapor in the face.

    The other alternative is to vent through the crawl space to the side of the house which is not visible from the street. But because the crawl space is lower than the garage, only a boiler with vent connectors close to the floor would be possible - this would seem to eliminate any wall hung boiler. The only boiler we've found that meets this criteria is the Munchkin. However, I've read a number of negative comments regarding the Munchkin and we really like the Buderus. Does anyone have any advice? Is there another well regarded, high efficiency boiler that sits low to the floor?

    BTW, I wrote The Wall 2 years ago about Runtal baseboards. We had them installed in a kitchen addition and dining room and we love them.

    Thanks,

    Best practices for venting

    this type of boiler are something like this:

    Four feet to the side of a window or other wall penetration;

    1 foot above the highest recorded snow accumulation;

    7 feet above a walkway.

    These safety provisions may vary according to what Code is used in your area. Exhaust gases may contain Carbon Monoxide, especially if the boiler is malfunctioning or wasn't set up properly, and you sure don't want that getting into the house. So it's not a good idea to play fast-and-loose with this.

    boiler for difficult location

    Thanks for the response. We don't have any problem with clearances for venting either through the front of the house or to the side. The issue is mostly esthetic, and for that reason we would prefer venting to the side of the house through the crawl space. However, this option would require vent connectors close to the floor. The Munchkin would meet this requirement but we would like to know if there are any other high efficiency boilers that sit on the floor and are as well regarded as the Buderus?
    Any advice you can give will be greatly appreciated. We just don't know what to do.
