How many fixtures can 7.5 GPM run at once?

About two showers plus a sink in a mild climate. Cold inlet water and long pipe runs cut that.

Does it work without electricity?

No. It needs a 120V outlet for ignition and controls, so it stops in a power outage.

Can it be installed outdoors?

No. It is an indoor model and must be vented to the outside.

What maintenance does it need?

Annual descaling with vinegar or a flush kit, more often in hard water.

How does it compare with Rinnai or Navien?

Similar flow and efficiency, but those brands offer longer heat exchanger warranties and wider service networks.

The heater and mounting hardware. Venting, gas flex line and water connectors are usually sold separately.

Our take on the Casa Home Living Natural Gas Tankless Water Heater Indoor

The Casa Home Living is an indoor, natural-gas tankless water heater rated at 7.5 GPM, enough for two showers plus a sink running at once in most homes. It needs a 120V outlet for its controls and ignition, and it mounts on a wall to free up floor space. The 5-year heat exchanger warranty is shorter than the 10-15 years names like Rinnai and Navien give on their heat exchangers. Reviewers of this class of unit praise endless hot water and lower gas use, but installers warn that venting, gas line sizing and annual descaling decide how well it holds up.
