How many fixtures can it run at once?

At 4.8 GPM it covers one shower plus a sink comfortably. Running two showers at once in cold weather will push past what 110,000 BTU can heat.

Does it work in cold climates?

It works, but flow falls as incoming water gets colder because the BTU rating is fixed. In very cold groundwater, expect to run one fixture at a time.

What is needed to install it indoors?

A propane supply line, a properly sized gas regulator, water connections and venting to the outdoors. The vent pipe is included, but gas work should be done by a licensed installer.

Is it a whole-house heater or for a single room?

It is sized for a small to mid-size whole house or a large single use such as a cabin or addition. Large homes with several bathrooms need a higher-BTU model.

Does it need electricity?

Yes. The ignition, display and controls draw power, so it needs a standard electrical connection in addition to propane.

The heater and a vent pipe. Gas lines, water fittings and mounting hardware are typically supplied by the installer.

Our take on the MYACUC Indoor Propane Tankless Water Heater 4.8 GPM 110,000 BTU

The MYACUC is an indoor, propane-fired tankless water heater rated at 4.8 GPM and 110,000 BTU, enough for one shower plus a sink or two at once in a small to mid-size home. It runs on demand, so there is no tank to recover and no standby heat loss, and it includes a vent pipe and an LED touch display for setting temperature. Its output sits in the middle of the tankless field: stronger than small point-of-use units, weaker than 180,000 BTU whole-house models that feed several bathrooms at once. It suits households of two to four in mild climates; in cold incoming water the flow it can heat drops, as with any unit of this size.

Pros

4.8 GPM and 110,000 BTU handle a shower and a tap at once
Tankless design frees floor space and avoids standby losses
LED touch display makes temperature setting straightforward
Vent pipe included, cutting extra parts to source
Propane fuel suits homes off the natural gas grid

Cons

Output drops with cold incoming water, so winter flow is lower than the rating
Indoor installation needs proper venting and gas supply work
No built-in recirculation, so hot water takes a moment to reach distant taps
Less capacity than high-BTU whole-house units for multiple bathrooms
Brand is little known, so parts and service support are harder to confirm
