Our take on the Rheem Performance Plus GPM Liquid Propane Indoor

The Rheem Performance Plus is a non-condensing indoor tankless water heater that runs on liquid propane and delivers up to 9.5 GPM, enough for roughly three showers at once. Its standout feature is built-in EcoNet Wi-Fi, so you can set temperature and monitor the unit from a phone. It suits households replacing a tank heater that want endless hot water and floor space back. Against condensing rivals it is simpler and cheaper to install, but less efficient; against smaller tankless units it offers more flow for larger homes.

Questions and answers

Is this a good fit for a large family?
Yes, if your propane supply and gas line can support it. The 9.5 GPM capacity covers about three showers at once, so a busy household gets continuous hot water.
How does it differ from Rheem's condensing tankless models?
This is non-condensing, so it vents more simply and usually installs for less, but it is less efficient. Condensing units capture more heat and cost more upfront.
Does it work without Wi-Fi?
Yes. The heater runs on its own; EcoNet Wi-Fi adds remote temperature control and monitoring but is not required for operation.
What maintenance does it need?
Plan on annual descaling, especially with hard water, plus a check of the venting and gas connections. Skipping it shortens the unit's life.
Can it replace a tank water heater directly?
It can, but the install differs: it needs a suitable propane line, indoor venting and wall mounting. A licensed installer should size the gas supply.
Where is the Rheem Performance Plus GPM Liquid Propane Indoor cheapest?
At The Home Depot, for $1,149.00, as of our latest check.
