Water Treatment

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

I have a Keystoker KC-10 and recently made the switch over from outdoor wood/coal boiler. I need to know what is recommended for boiler water treatment and what type of antifreez could be used.

Thanks

Standard boiler antifreeze (not the same as automotive) can be used, but I would carefully consider if it is necessary. Not only does it try to leak out of every valve stem and imperfect joint, it is pretty expensive. Have you priced out the quantity required to treat your system?

They make "conditioner" that can be added to boiler water, but not all of the products are compatible with antifreeze. Your local plumbing supply house should have something that will work either way.

I live alone so incase something happens to me that I cant tend the fire I was think of a antifreeze just for insurance since my KC-10 is out in my shop, no backup heat source there.

As far as treatment goes I am assuming its primary function would be to inhibit rust and corrosion?

I think most outdoor wood/coal boilers are open systems, not under pressure. I don't know for sure but maybe they are more prone to problems with the water. Most domestic boilers (closed systems under pressure) don't have any conditioner in the water.

i wanted to run anti freeze, or glycol in my system untill I learned more about it. instead I just keep an eye on it. I think the only way that keystoker is going to lose fire is if you let it run out of coal. good luck!
