Coal Boilers

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

In typical residential construction and actual use of the rooms it's not practical in most cases to exclusively have radiant floor heating. But selective radiant floor heating, bathrooms, kitchens and on slab below grade family rooms are good ideas. You have to understand where convection heating with baseboard is good vs. where it is not. Baseboard under windows negates the coal draft effect (good). Baseboard in rooms with very high cathedral ceilings causes all the heat to be up high (bad). You can have radiant heat in a room without the radiant surface being the floor. Properly placed wall or even ceiling mounted radiant panels supplement convection heating well. You must understand the design principles to get it right.

Any links? My google skills have fallen short on this one :(

It's called a 'Hot Foot'.. highest slab temperture that is comfortable is around 85-90*.. you need a mixing valve to moderate the water temp usually.

All great boilers, but your list looks upside down to me. :)
Nothing is impossible for people who don't have to do it themselves.

hahaha, OK thanks. I thought I had read a post that said I could use full temp water for the radiant heat in the slab foundation.
