Product details

Space heating capacity reaches 130,000 BTU on this model, with domestic hot water rated at 199,900 BTU from the same natural gas cabinet. It carries the largest heating output in the NCB-H series, aimed at houses where the boiler load rather than the shower load sets the size.

Two stainless steel heat exchangers separate the duties, and the burner turns down 15:1 on hot water and as far as 10:1 on heating. Three zone pumps or three zone valves land on built-in powered terminals. Field conversion between natural gas and propane is supported up to 10,100 feet, and venting runs 2-inch to 65 feet or 3-inch to 150 feet. Warranty is one year labor, five years parts, ten years 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.
