Vesta VRP PLUS-150 is a gas tankless water heater from Vesta rated 4.7 GPM at a 0.95 UEF — 178 therms/yr certified use, 150k BTU/h input.
Our take
Vesta's PLUS treatment of the 150 platform buys real gains: 4.7 GPM rated against the base model's 4.3, with 99% recovery efficiency — joint-best in the mid-size class — and documented direct venting over 2-inch pipe. This particular certification posts a 0.95 UEF, about $258 a year on natural gas (its VTP-150 twin certifies 0.96), with propane covered too. Winter output is roughly 4.1 GPM at a 70 °F rise. The 27.6-inch height is the tall tier of the class; depth is a reasonable 11.6 inches. Single badge.
Best for: Above-median rated flow with top-tier recovery in the mid-size class.
Trade-off: Tall-tier cabinet, and this variant certifies a point under its own twin's UEF.

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 VRP PLUS-150 at common temperature
rises (a typical shower uses about 2 GPM of mixed water):
Yes, the Vesta VRP PLUS-150 holds a current ENERGY STAR certification for water heating efficiency (UEF 0.95).
How much does the Vesta VRP PLUS-150 cost to run per year?
About $258 per year at national average energy rates, based on its certified annual energy use under the DOE test draw pattern. Your rate and usage change this figure.
