Product details

Rated 180,000 BTU, the 210S2 uses condensing heat recovery to pull usable energy from exhaust that a tank heater would vent away. Flue temperatures come down far enough to run SCH 40 2-inch pipe up to 75 feet, which simplifies the vent path in a retrofit.

Dual stainless steel heat exchangers, 20 ppm NOx, and a field-convertible gas system are standard, and a half-inch gas line will supply it at distances up to 24 feet. The EZNav multi-line panel with HotButton handles setup and operation. Cascading covers up to 32 units, common venting up to 12. Packed with the heater are a wall bracket, four tapping screws and anchors, two vent terminators, and four wall flanges.

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.
