Want to install a new coal stoker in my attached, well insulated, radiant heated garage. I am concerned that the heat given off from the boiler body will keep the space too warm. Is this a valid concern ? If so, which stoker is best for the task ? New to the forum, thanks for any advice.

Have pretty much decided on the DS machine aqua stoker, love the viewing glass door. Just concerned with excessive radiant heat into the room. Any experiences ?

Very new. I doubt that DS has sold more than a handful of these yet. They do look mighty nice though.

An open fire in a garage may not be entirely safe though.

Ignition sources in residential garages can be safe and accepted if you follow the various regulations on e of which is below . Local jurisdictions have authority and more of regs like this may be applied. Some state combustion air must be taken from outside and not the residential portion of the building and more..... research required.
UPC 507.13 Installation in Garages.
Appliances in garages and in adjacent spaces that open to the garage and are not part of the living space of a dwelling unit shall be installed so that burners and burner-ignition devices are located not less than 18 inches (457 mm) above the floor unless listed as flammable vapor ignition resistant. [NFPA 54:9.1.10.1]

That means you will either need to install the boiler on a pedastal or keep all gas jugs,& all gasoline powered vehicles including lawn/garden equipment out of the garage.

OR.... Risk the possibility of fire & gasoline fumes going BOOM.. :what: :o

Which unit sheds the least heat ???
Is that like asking if Ford,Chevy,Toyota ,Dodge or Ram ? makes the best truck.??? :)

A new design like the DS boiler should likely have very good insulation..
Insulating the pipes real good will make a huge difference in shed heat too..

If you are going to sit and watch the fire in the garage the glass would be nice. My boiler doesn't have a glass door and I'm glad there is one less thing to worry about.

I personally feel more comfortable with my coal boiler in my attached garage than in a basement. Attached garages are separated by a fire wall, where your basement is right under your living space. Many times with low ceiling heights and exposed floor joists. I will check all applicable codes before install though.

I believe the risk from fire with a coal fired boiler is as low as an oil or gas boiler. I have one in my basement and my ceiling is only 6'5" at best. That said, you should be comfortable in your house.

I think all of the units with insulated cabinets are about the same. I went a step farther on my EFM and insulated the piping, base and fire door also.

If your garage is tight you will probably need to add a vent for makeup air.

I agree with David's comments on fire risks. If the OP is switching from wood I understand the sensitivity to fire issues, but coal does not generate creosote and is comparatively difficult to ignite, so it doesn't carry risks comparable to wood. That said, handfired units and some stokers do carry a risk of "puff-backs", as discussed in other threads. I'm more concerned about fire issues with my gas boiler than I ever have been with coal.

Thanks for all the he replies can't wait to get it all set up and post some pics. The ds stoker is very new, but looks to have a lot of the great features from other boilers put together. Being able to see the coal fire without opening the door just seems like a cool feature also. Time will tell.

There are pictures around of guys that reinsulated the boiler with foil backed foam. Then reinstall the sheetmetal, might need to get creative.

I doubt the insulation is anything crazy, most cases it's nice to have the boiler shed some heat to the space around it.

Most of my heat in the basement is from the piping (tubing), not the boiler itself. I have 500 feet of un-insulated tubing through out my basement. Basement stays 68* with piping only. Yes, some heat comes from the boiler, but no where near enough to heat my 65' basement to an even 68* through out. Like has already been said, a little heat from the boiler can be a good thing. If concerned of too much heat loss, insulate the piping.
