Product details

At 199,900 BTU, this is the larger of the two residential NFB-H boilers. Its fire tube exchanger, patented and made of stainless steel, is shaped to avoid the concentrated weld stress that shortens the life of other exchangers, and a dual venturi arrangement holds combustion steady across the turndown range.

Controls use a text display with a quick dial wheel and a startup wizard. Three zone valves or three zone pumps wire straight into built-in powered terminals. Conversion orifices for liquid propane and high-altitude natural gas are supplied. Venting is 2-inch PVC to 65 feet, or 3-inch to 150 feet. In residential use the limited warranty runs one year labor, five years parts, and ten years on the heat exchanger.

What people say about buying from us

4.8 out of 5 from 6 store reviews. These cover the buying experience across our catalog, not this product alone.

  • Arrived early and packed properly

    Ordered on a Thursday and it was on a pallet outside my garage Monday morning. Every board was numbered and the hardware came in labelled bags, so we did not have to guess at anything. Two of us had it standing by Sunday afternoon.

  • Lumber quality is genuinely good

    I have built two of these from other brands and returned one for warped boards. Not a single warped piece in this kit. The kids have been on it every day since we finished it.

  • Correct weight, factory sealed, clean invoice

    Ordered Thursday, on the truck Friday. Cylinder was sealed and the weight was exactly right. The invoice had everything my bookkeeper needed, which is more than I can say for the supplier I was using before.
