What size home does 4.8 GPM suit?

It fits a small home or apartment with one bathroom. Running a shower and a dishwasher at the same time will strain it.

Does it work with natural gas?

No. It is built for propane only, so it needs a propane tank or line and a properly vented indoor location.

What is included in the box?

The heater and a vent pipe. Gas line, water connections and mounting hardware are not listed.

How is the temperature controlled?

Through the LED touch display, which sets the outgoing water temperature. The unit modulates its burner to hold that setting within its capacity.

Can it replace a tank water heater?

Yes, for a small household. Check that your propane supply and venting can handle 110,000 BTU before swapping.

Does it need electricity?

Yes. The display and ignition need power, so plan a nearby outlet along with the propane and water lines.

Our take on the MYACUC Indoor Propane Tankless Water Heater 4.8 GPM

The MYACUC is an indoor, propane-fired tankless water heater rated at 4.8 GPM and 110,000 BTU. It heats water on demand, so there is no tank to keep warm between draws. An LED touch display sets the output temperature, and a vent pipe is included for indoor installation. At this capacity it covers a small household with one bathroom well, but it is below the 7 to 9 GPM whole-house units that cost more and need larger gas lines.
