Rheem manufactures more water heaters in North America than any other company. Their residential lineup runs from entry-level economy tanks sold at Home Depot to the ProTerra — the best heat pump water heater available for residential use. Here is a complete guide to the Rheem residential product family.
| Series | Description | Tank Warranty | Best For |
|---|---|---|---|
| Performance (XR) | Entry level | 6 years | Budget replacement |
| Performance Plus | Mid-tier | 8 years | Most homeowners |
| Performance Platinum | High-efficiency | 12 years | Long-term value |
| ProTerra Heat Pump | Heat pump hybrid | 10 years | Lowest operating cost |
| Prestige Condensing Tankless | Tankless gas | 12-yr heat exchanger | Unlimited hot water |
The Rheem Performance Plus is the mid-tier tank series and the unit WaterHeaterMan uses for standard gas and electric tank installations. The gas units are available in 40, 50, and 75-gallon capacities with BTU inputs ranging from 36,000 to 50,000. The 8-year tank warranty puts it above the economy tier without the premium price of the Platinum series. For most homeowners, the Performance Plus hits the right balance of quality, warranty coverage, and cost.
The Platinum series features a 12-year tank and parts warranty — the longest in the Rheem residential gas lineup. It also features a self-cleaning dip tube that reduces sediment accumulation, higher first-hour ratings than the Performance Plus at equivalent capacity, and improved insulation that reduces standby heat loss. If you're planning to stay in your home for 10+ years and want the lowest total cost of ownership in the tank category, the Platinum is worth the additional cost.
The ProTerra is Rheem's flagship heat pump unit and is widely considered the best residential heat pump water heater currently available. Key specs: 50-gallon capacity, COP of 3.75 (meaning it delivers 3.75 BTUs of heat per BTU of electricity consumed), integrated WiFi controls via the EcoNet app, and a 10-year tank and parts warranty. It qualifies for the federal 30% tax credit and most utility rebates. The ProTerra is the right choice for electric water heater customers who want the lowest possible operating cost.
Rheem warranty claims are handled through Rheem directly or through your installing contractor. To register your Rheem product (required to activate the full warranty term), go to Rheem.com and register within 30 days of installation. WaterHeaterMan provides all the information needed for registration — serial number, model number, and installation date — on your installation receipt.
Rheem sells through two channels: retail (Home Depot carries the Performance series) and wholesale/contractor (where Performance Plus and Platinum series are available). The units WaterHeaterMan installs come through wholesale distribution — the same channel that professional plumbing contractors use. This means the units we install are not the same models available to DIY customers at retail.
