How much hot water can it deliver at once?

It is rated up to 6.4 GPM on propane, enough for two showers plus a running appliance in most homes. Actual output depends on incoming water temperature and gas supply.

Can it be installed indoors?

No. This model is built for outdoor installation and vents directly. Indoor installs need a different, indoor-rated model.

Does it work in freezing climates?

Outdoor tankless units are vulnerable to freezing. In cold regions, an indoor model or freeze protection is the safer choice.

What maintenance does it need?

Tankless heaters need periodic descaling, more often in hard-water areas, plus a check of the inlet filter. Annual service keeps performance steady.

What fuel does it use?

It runs on propane, so the home needs a propane supply and a gas line sized for the unit's input.

Is it worth it over a tank heater?

If you want endless hot water and freed floor space and have an outdoor wall and propane, it is a strong fit. If install cost or hard water is a concern, weigh the upkeep.
