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

What it delivers

The VEVOR JSQ30-B 100,000 BTU Propane Tankless Water Heater is a propane tankless with a 100,000 BTU/h burner.

Flow depends on how cold the incoming water is. Our estimate from its input: 3.4 GPM at a 45°F rise, falling to 2.2 GPM at 70°F, which is 1 shower at 2 GPM on a cold-climate winter day. Check it against your own fixtures.

Gas load at full fire: about 1.1 gallons of propane an hour. An older half-inch line that already feeds a furnace often can't spare that, so have a gas fitter check the pipe size and run.

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.

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

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

Questions buyers ask

How many showers can the VEVOR JSQ30-B 100,000 BTU Propane Tankless Water Heater run at once?

From its 100,000 BTU/h input we estimate about 3.4 GPM at a 45°F rise and 2.2 GPM at a 70°F rise, so 1 two-GPM shower with mild inlet water and 1 in a cold winter. The maker's flow chart for this model is the final word.

What size gas line does the VEVOR JSQ30-B 100,000 BTU Propane Tankless Water Heater need?

At full fire it uses about 97 cubic feet of natural gas an hour or 1.1 gallons of propane. The pipe size depends on the length of the run and every other gas appliance on it; the maker's manual and a licensed gas fitter decide it.
