$/GPM is the price divided by the hot water flow the heater delivers at a 45 °F temperature rise, worked out from its gas input and UEF. "Box GPM" is the maker's own maximum, often quoted at a much smaller rise, so it is shown but not ranked on. Your rise depends on your incoming water: the sizing calculator works it out from your ZIP.

Is it big enough for my house?

At full fire this heater puts about 156.6k BTU/h into the water. Enter your household and ZIP code in the sizing calculator: it works out how cold your water arrives in winter, the peak flow your showers and taps need, and whether this heater keeps up. Open the sizing calculator.

Install: needs a gas line sized for its full BTU input and a 120 V outlet for the controls.

GPM figures are ours: heat output (input × UEF) ÷ (500 × rise), capped at the box maximum.

VEVOR lists 'Capacity 8 Gal / 30L' for this tankless unit; the page's flow range (30 L/min / 7.93 gal/min) and description confirm it is the 8 GPM maximum flow. Rise for that flow not stated. Fan-assisted (anti-backflow fan), 120 V. No UEF, warranty or heat-exchanger warranty published (the store's generic 12-month warranty badge only). Max output temperature 149 °F; min start flow 2.5 L/min (0.66 GPM).
