Our take on the Tankless Water Heater 4.3Gal 100000 BTU Gas Indoor, Instant Hot Water Heater with Smart Temp Control & LED Display, Whole House, Silver Gray

The RoiXst is an indoor, whole-house gas tankless water heater rated at 100,000 BTU/h with a 4.3-gallon-per-minute flow. It holds temperature within about 1°F, shows it on an LED display, and adds leak, flameout, overheat and freeze protection. The oxygen-free copper heat exchanger resists rust, and a conversion kit lets it run on propane or natural gas. It suits households replacing a tank unit who want endless hot water and a small wall footprint; at this capacity it runs a couple of fixtures at once, not several showers, so larger homes should look at higher-BTU models.

About the Tankless Water Heater 4.3Gal 100000 BTU Gas Indoor, Instant Hot Water Heater with Smart Temp Control & LED Display, Whole House, Silver Gray

This is an indoor gas tankless water heater rated at 100,000 BTU. It heats water on demand, so it needs no storage tank. It is intended for whole-house use and can supply several outlets at the same time.

The tank is made of oxygen-free copper for efficient heat exchange and rust resistance. A smart control keeps the temperature within +/- 1°F, and an LED display shows it in real time. Safety protections include leakage, flameout, overheating and freeze protection.

Questions and answers

How many fixtures can it run at once?
At 4.3 GPM it handles one shower plus a sink comfortably. Running two showers or a shower and a dishwasher together will split the flow and can cool the water.
Does it work with both propane and natural gas?
Yes. The unit is set up for either, and a conversion kit is included so you can match it to your home's gas supply.
Can I install it myself?
It needs a gas line, a direct vent to the outdoors and standard 1/2-inch NPT water connections. Most buyers use a licensed plumber or gas fitter for the gas and venting work.
Does it need electricity?
Yes. The controls, LED display and ignition draw power, so the unit needs an electrical connection in addition to gas and water.
Will it give instant hot water at the tap?
No. Like most tankless units it heats on demand but still waits for water to travel through the pipes, so there is a short delay before hot water arrives.
Where can it be mounted?
It is for indoor installation only and must be vented directly to the outside. It measures about 24.8 x 12.6 x 6.3 inches and weighs 33.1 lbs.
