Vesta VRS PLUS-150 is a gas tankless water heater from Vesta rated 4.6 GPM at a 0.96 UEF — 176 therms/yr certified use, 150k BTU/h input.
Our take
The VRS badge on Vesta's mid-size platform certifies a 0.96 UEF — 79th percentile for the class, roughly $255 a year on natural gas — with the cohort's joint-best 99% recovery efficiency and a class-median 4.6 GPM rating. Expect about 4.1 GPM sustained at a 70 °F winter rise. Direct venting over 2-inch pipe, 0.5 GPM activation, and dual-fuel certification make it an easy install; the 27.6-inch height is the one dimensional demand. Sold under the Vesta name alone, with no rebadged twins in the certified record.
Best for: Efficient mid-size duty with a simple 2-inch direct-vent flue.
Trade-off: A tenth less rated flow than its VRP PLUS stablemate.

Real flow rate by climate
A tankless heater's usable flow depends on how far it must raise incoming water
temperature. Sustained hot-water flow of the Vesta VRS PLUS-150 at common temperature
rises (a typical shower uses about 2 GPM of mixed water):
Yes, the Vesta VRS PLUS-150 holds a current ENERGY STAR certification for water heating efficiency (UEF 0.96).
How much does the Vesta VRS PLUS-150 cost to run per year?
