VEVOR JSQ30-A 100,000 BTU Tankless Water Heater: 100,000 BTU/h

What it delivers

The VEVOR JSQ30-A 100,000 BTU Tankless Water Heater is a non-condensing gas tankless with a 100,000 BTU/h burner.

At a 45°F rise (mild inlet water to a 120°F set point) it holds about 3.4 GPM, 1 shower at 2 GPM; in winter, at a 70°F rise, about 2.2 GPM, 1 shower at 2 GPM. Run your house through the planner.

At full fire it burns about 97 cubic feet of natural gas an hour. The gas line has to carry that on top of the furnace, range and dryer; a gas fitter sizes the pipe from its length and the total load.

Non-condensing indoor units run hot exhaust and vent in the maker's listed vent system (often stainless Category III), which costs more than plastic.

The listing describes its venting as: direct vent.

From the listing: features: LED Display, ±1℉ Precision Temperature Control; connections: 1/2 inch NPT; material: Carbon Steel; model: JSQ30-A.

The listing gives dimensions of 13.78 in (W) x 21.65 in (H) and a weight of 19.8 lb.
