Bosch TR4000C-10*
0.95 UEF DOE CCD · 2026-09-19Grade F: where this UEF sits among the 271 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tankless unit, very small draw pattern (small units - a single bathroom, or a point-of-use heater under a sink).
If you are checking the Bosch TR4000C-10*, an electric tankless unit, this is its annual energy use. It uses 622 kWh of electricity a year at the very small draw pattern, the standard daily hot-water usage DOE tests against. That sits 7 kWh above the 615 kWh median for its class.
Energy use per year
622 kWh a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.
That is above the median of 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 152 of 271, lowest energy first.
Solid line: this model (622 kWh). Dashed line: the class median.

The registry does not print the 622 kWh figure. This site calculated it from two inputs. The first is the registry's UEF, the ratio of hot water delivered to energy used, which is 0.95 for this model. The second is the DOE test's daily hot-water draw for the very small draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure applies only at that test draw, and this page has no data for other daily volumes. The comparison covers the 271 models registered as an electric tankless unit at the very small draw pattern. This model ranks 152nd lowest for energy use among those 271. That puts it in the second-highest quarter of its class for energy use. The method behind the annual energy and cost figures sets out each step.
The very small draw pattern covers small uses, such as a single bathroom or a point-of-use heater under a sink. The registry lists this model's maximum flow rate in gallons per minute as 1.1. That rating caps how much hot water the unit delivers at once. A site that fits this draw pattern and stays within 1.1 matches the conditions behind the 622 kWh figure. If a home needs more hot water at once than 1.1, its demand exceeds that rating. The registry data used here does not show how the unit performs at larger daily draws, so that information is not available on this page. If you need a different fuel, space or size, the water heater selector by fuel, space and size filters the registered models.
This text does not give a running cost. The cost is your own utility's electricity tariff applied to 622 kWh a year, so the page calculates it from your ZIP code. You can run that step in the running-cost calculator for your own ZIP code. The 7 kWh gap above the 615 kWh class median is also priced at your tariff, so its cost effect depends on your rate too. The installed price in its own block on this page is a modeled range, not a quote, and it shows its own source and date. If you are verifying a like-for-like swap, use the same-class replacement search by model number. It lists other models from the same class of 271 at the very small draw pattern.
