It is not suitable for outdoor use, as it is rated for indoor installation only. Homes above 2,000 feet elevation should avoid this unit, as performance may drop. If you require propane fuel, you must select a different variation from the available options.
Verdict: The LiberLive Nature Gas Tankless Water Heater offers reliable on-demand hot water for small to medium indoor households. Its 80,000 BTU output and 3.6 GPM flow rate make it a practical choice for space-constrained living.
Key specs for this unit
80,000 BTU
This heating capacity determines how quickly the unit raises water temperature. You get consistent hot water even when incoming supply is cold. Higher BTU ratings support faster recovery times. Compare this to lower-output models if you need rapid heating for multiple fixtures. It ensures steady performance during peak usage hours.
3.6 GPM
Gallons per minute indicates the maximum water volume the heater can process. This flow rate supports two to three simultaneous water points. You can run a shower and a sink without significant pressure drops. Compare this to single-fixture units if your household has higher demand. It defines the practical limit for concurrent usage.
Natural Gas
This fuel type requires a connection to your home's natural gas line. It typically offers lower operating costs compared to propane or electric alternatives. You need an existing gas infrastructure to install this unit. Compare this with propane models if you lack municipal gas service. It dictates the required utility connection for operation.
120V AC
This voltage requirement means the unit plugs into a standard household outlet. You do not need specialized high-voltage wiring for electrical components. It powers the control panel and safety sensors. Compare this with 240V electric models that require dedicated circuits. It simplifies electrical installation for most residential settings.
Indoor
This installation location specifies that the unit is designed for interior spaces. It requires proper ventilation and clearance from combustible materials. You must follow indoor safety codes regarding airflow and exhaust. Compare this with outdoor models if you need exterior placement. It defines the necessary environment for safe and effective operation.
Design and build details
The unit measures 22.1 x 14.2 x 6.7 inches. This compact footprint allows for wall-mounted installation in tight spaces. You can place it in small laundry rooms or apartments without consuming valuable floor space. The gray finish is listed as durable and easy to clean. According to the listing, the compact size helps reduce standby energy waste compared to traditional tank models.
Controls are managed via an LED screen. This digital interface displays current settings and status clearly. You can adjust the temperature range to maintain consistent warmth. The adjustable control helps prevent sudden hot or cold spikes. This stability is important for households with infants or elderly users who need precise water temperatures. The layout keeps the display visible for easy monitoring.
The heat exchanger is made of copper. This material is noted for being oxygen-free. Copper conducts heat efficiently, which supports the 80,000 BTU output. The unit is designed for indoor use only. It requires standard 1/2 inch NPT fittings for water connections. You must connect it to a 120V AC power source for the electronic controls and safety fans. The design includes safety sensors for dry burning and overheating protection. These features ensure the unit operates safely within its specified indoor environment.
Setup and everyday use
You must install this unit with a licensed plumber. The manufacturer does not recommend installation above 2,000 feet elevation. The unit requires 120V AC power and connects to natural gas lines using standard 1/2" NPT fittings. It fits vents with a 3" outer diameter. These standard connections make it compatible with most U.S. homes, provided you follow local codes.
Daily operation begins with the LED screen control. You adjust the temperature settings to find your preferred warmth. The adjustable range helps you avoid sudden hot or cold spikes. This precision control ensures consistent water temperature for your household. The 80,000 BTU heating power allows the unit to support two to three water points at the same time. You can run a shower and a sink simultaneously without losing pressure or heat.
The oxygen-free copper heat exchanger transfers heat efficiently. This design cuts standby energy waste, which is common in traditional tank heaters. The compact wall-mounted footprint saves space in small laundry rooms or apartments. The gray finish is listed as durable for indoor use.
Safety features engage automatically during operation. The unit monitors for dry burning, overheating, flame-outs, and carbon monoxide leakage. A powerful fan ensures safe exhaust and stable combustion. You use the water with confidence, knowing these protections are active. The LED display shows your current settings, allowing you to monitor performance easily.
Before You Buy This Heater
Before you install this LiberLive unit, verify your home’s gas line capacity. The 80,000 BTU output requires sufficient gas pressure to maintain the stated 3.6 GPM flow rate. Check that your electrical panel supports the 120V AC requirement for the control board and fan. Ensure you have standard 1/2" NPT fittings and a venting solution compatible with the 3" outer diameter exhaust. Since this model is rated for indoor use only, confirm your installation site meets ventilation codes. You will need a licensed plumber for the gas connection and a qualified technician for the electrical hookup. The compact 22.1 x 14.2 x 6.7 inch size fits most utility closets, but measure your space carefully. Unlike larger whole-house models, this unit suits apartments or small homes. It may struggle to supply hot water to multiple distant showers simultaneously. Consider your peak usage habits. If you run two showers at once, this 3.6 GPM limit might cause temperature drops. Review your other options in the Tankless Water Heaters guide if you need higher flow rates for larger families.
Check before you buy
- Confirm gas line pressure supports 80,000 BTU input
- Ensure 120V AC power is available near unit
- Check 3" vent compatibility and indoor clearance

Frequently asked questions
Is this LiberLive unit suitable for outdoor installation?
No, this model is designed specifically for indoor use. The manufacturer lists it as an indoor natural gas tankless water heater. Outdoor units require different weatherproofing and venting standards. You should not place this gray unit outside where it could be exposed to rain or snow. Stick to indoor locations like utility rooms or basements.
What are the exact dimensions of the LiberLive 3.6 N2?
The unit measures 22.1 inches in height, 14.2 inches in width, and 14.2 inches in length. These compact dimensions allow for wall mounting in tight spaces. You can fit it into small laundry rooms or apartments without taking up floor space. The gray finish is noted for durability in these indoor settings.
Does this heater require a special gas line connection?
You must connect this unit using standard 1/2-inch NPT fittings for the natural gas line. This is a common fitting size for residential gas appliances. Ensure your existing gas line can support the 80,000 BTU input required for the stated 3.6 GPM flow rate. A licensed plumber should verify the gas pressure before installation.
Can I install this above 2,000 feet elevation?
The manufacturer does not recommend installation above 2,000 feet elevation. Higher altitudes affect air density and combustion efficiency for gas appliances. Installing it above this limit may cause performance issues or safety concerns. You should consult local codes or the manufacturer for specific derating instructions if you live in a high-altitude area.
What power source does the LiberLive Nature need?
This unit requires a standard 120V AC electrical connection. You need a dedicated circuit that can support the power draw for the control board and ignition system. The 80,000 BTU heating element relies on this electricity for operation. Ensure your electrical panel has the capacity to handle this load safely during installation.
Is this model good for large family homes?
This 3.6 GPM model is best for small indoor setups. It supports two to three fixtures simultaneously, which may be tight for large families. Larger homes often need higher flow rates or multiple units. If you have high simultaneous demand, this compact unit might struggle to maintain temperature at all outlets during peak usage.
