NCB-250 Outdoor Wood Boiler


MSRP $6,980
Coal Model $600 extra

The NCB-250 is one of the most popular models. It can heat most average sized homes. It is also a good choice if your house falls into the size range for a smaller model but you may want to heat a shop or other building
Draft air enters from the back into the firebox under the grates to get a hot clean burn. As with all models that Nature's Comfort builds, it has an easy read stainless steel float gauge.
It is rated to be able to heat up to a 6000 sq ft house with good insulation or 5500 sq ft if also heating domestic hot water.
These ratings are with well seasoned hardwood and just a general reference.
In southern Wisconsin they should be reduced by about 33% with average wood.
Green wood would have further reduce capacity
