Rheem Performance 10-Gallon Point-of-Use Mini-Tank Electric Water Heater
Rheem Performance 10-Gallon Point-of-Use Mini-Tank Electric Water Heater Review
The Rheem Performance 10-Gallon Point-of-Use Mini-Tank Electric Water Heater (XE10P06PU20U0) is the mid-tier mini-tank — 10-gallon capacity between the under-sink 6G and the small-room 20G. 120V or 240V wiring options, 6-year warranty. The right pick for small remote bathrooms, pool houses, and applications where 6 gallons isn't enough but 20 is overkill.

Who this model is for
Small remote bathrooms with sink + low-flow shower (the 10-gallon supports a 3–4 minute shower at 1.5 GPM head before depletion), guest cottages / pool houses with low-frequency use, RV/fifth-wheel installs where 6G is undersized, garage apartments with intermittent occupancy.
For high-frequency daily-use small bathrooms, step up to Performance 20G Point-of-Use for ~$80 more. For single under-sink fixture, drop to Performance 6G Mini-Tank. For whole-house 1–2 person service, Performance 30G Short Electric is the right scale.
Where it beats the alternatives
Vs Performance 6G Mini-Tank: 10G adds ~$60 for 4 extra gallons stored capacity — meaningful difference for shower-supporting applications.
Vs Bosch Tronic 3000 T 7G: Rheem 10G has more capacity at similar price. Both Euro-engineered build quality (Bosch literal; Rheem comparable). Rheem availability is broader.
Vs running hot-water line from main heater: for outbuildings 50+ ft from main heater, trenched plumbing runs $1,500–$4,000. Mini-tank install ~$400.
Vs Eemax point-of-use tankless electric: tankless needs 240V wiring and 60+ amps for shower-supporting flow. Mini-tank plugs into 120V (or basic 240V). For low-demand applications, mini-tank simplicity wins.
Where it falls short
10 gallons supports a short shower at low-flow (1.5–2 GPM head). At 2.5 GPM head, the tank exhausts in 3–4 minutes — fine for guest occasional use, marginal for daily residential.
1440W (120V) or 2000W (240V) element. Recovery is moderate — after full depletion, 60–80 minutes for full reheat.
18" cube doesn't fit under most standard sinks — typically needs cabinet, closet, or wall-mounted location.
120V plug-in is convenient but caps the element power. 240V hardwire variant has 2x faster recovery.
1-year parts warranty (vs 6-year tank).
Install considerations
120V plug-in or 240V hardwire — verify circuit. 1/2" or 3/4" NPT plumbing. Wall-mount bracket included. Drain pan recommended.
Install cost: $200–$450 for typical mini-tank plumbing.
Maintenance
- Annual flush
- Anode check year 4, replace year 5–6
- T&P valve test annually
- Element inspection year 5
Bottom line
The Rheem Performance 10G Mini-Tank (XE10P06PU20U0) is the mid-tier point-of-use electric — 10 gallons, 120V/240V configurations, 6-year tank warranty. Right pick for small remote bathrooms, pool houses, and applications between 6G under-sink and 20G small-room. For larger applications step up to 20G Point-of-Use; for under-sink single-fixture drop to 6G Mini-Tank.
