What’s Included in the Box

Opening the box, we found the packaging to be secure and professional. The contents are straightforward, which is typical for this category. Here’s what you get:

• The main Novieex tankless water heater unit (Pearl Grey finish).
• A pre-assembled flue pipe (exhaust vent) for horizontal venting.
• A user manual and installation guide.

The build quality feels solid upon first inspection. The metal casing is robust, and the connections appear to be of standard quality. It’s important to note that this is a best indoor propane tankless water heater kit, but it does not include several critical installation components. You will need to purchase separately: propane gas line fittings, water line fittings (1/2″ NPT), a condensate drain kit (if required by local code), vent pipe extensions or elbows (if the included piece isn’t sufficient), and a proper sediment filter. The lack of a comprehensive kit is a common point in any Novieex propane water heater pros cons discussion, as it adds to the initial project cost.

How to Use the Novieex Tankless Water Heater: Complete Guide

Step 1: Professional Installation is Non-Negotiable

This cannot be overstated. Installing a gas appliance, especially one that involves combustion venting, requires a licensed professional. They will handle:

1. Mounting: Securing the unit to a load-bearing wall with proper clearances.
2. Gas Connection: Running a properly sized propane line with a shut-off valve.
3. Water Connection: Connecting cold water input and hot water output with isolation valves.
4. Venting: Installing the included flue pipe to safely exhaust gases outdoors, adhering to local code for length and material.
5. Electrical: Plugging the unit into a standard 120V outlet (for the control system).

Attempting a DIY install can be dangerous and will void the warranty. This is a key factor when deciding if the Novieex tankless water heater is worth it, as installation can cost several hundred dollars.

Step 2: First-Time Power On and Setup

Once installed, your technician will power on the unit. You’ll use the LED touchscreen to set your desired temperature. We recommend starting at 120°F for safety and efficiency. The display will show error codes if there are issues with water flow, gas supply, or venting.

Step 3: Core Functions and Daily Use

Daily operation is simple: turn on any hot water faucet. The unit’s flow sensor activates the burner, and you’ll have hot water within seconds. The LED display will show the set temperature and real-time output temperature. You can adjust the temperature on the fly for different needs, like a hotter temperature for sanitizing dishes.

Step 4: Advanced Techniques

For larger homes, you can fine-tune the temperature rise. In colder climates, if your incoming groundwater is very cold, the maximum GPM at your desired temperature will be lower. Understanding this relationship helps manage expectations for simultaneous use.

Step 5: Annual Maintenance

To ensure longevity, descale the heat exchanger annually, especially if you have hard water. This involves circulating a vinegar solution through the unit using a service kit. Also, have a professional inspect the venting and gas connections yearly. For a detailed walkthrough, see our guide on maintaining your tankless water heater.

Step 6: Troubleshooting Common Issues

Common issues include error codes for “ignition failure” (check gas supply), “overheating” (check for low flow or scaling), or “no power” (check the outlet). The manual has a comprehensive error code list. Most issues require a professional’s touch.

Performance & Real-World Testing

Testing Methodology

We installed the Novieex RS-13 in a standard 3-bedroom, 2-bath home with moderate water hardness. Testing occurred over three weeks in winter, with an incoming groundwater temperature of approximately 52°F. We monitored for consistent temperature delivery, flow rate capability, and response time.

Performance Metrics

Hot Water Delivery Time: From a cold start, it delivered hot water (110°F+) to a faucet 20 feet away in about 15-20 seconds. This is standard for tankless units. Temperature Consistency: Once running, the temperature held remarkably steady at the set point, even when another faucet was turned on briefly. The modulation system works well. Maximum Simultaneous Use: As advertised, it comfortably handled a shower (2.5 GPM) and a kitchen sink (1.5 GPM) simultaneously with only a minor, barely noticeable dip in pressure, not temperature. This performance is central to answering should I buy a Novieex water heater for a family.

Real-World Scenarios

We simulated a busy morning: running a shower and a washing machine. The Novieex kept up, though the washing machine’s hot water fill was slower due to the shared flow. For back-to-back showers, there was zero wait time—a major win over tank heaters.

Claims vs. Reality

Novieex’s claim of “no noticeable temperature drop” during simultaneous 2-3 point use held true in our testing, provided the total flow was under 3.6 GPM. The claim of “lower bills” is plausible given the elimination of standby heat loss, but actual savings depend heavily on your previous system’s efficiency and propane costs. This hands-on testing forms the core of our Novieex RS-13 honest analysis.

Expert Tips for Maximum Value

Tip #1: Install a Whole-House Sediment Filter

This is the single best thing you can do for any tankless heater. It protects the delicate heat exchanger from scaling and debris, extending its life dramatically.

Tip #2: Set the Temperature Smartly

Set it to 120°F for most uses. This is safe, saves energy, and is hot enough for sanitizing. You can temporarily increase it for specific tasks.

Tip #3: Invest in a Service Valve Kit

For easy annual descaling, a service valve kit is essential. It allows you to pump descaling solution through the unit without disassembling pipes. Consider purchasing a maintenance kit when you buy the heater.

Tip #4: Understand Your Flow Rates

Add up the GPM of fixtures you might use simultaneously. If it exceeds 3.6, you’ll experience a pressure drop. This helps manage expectations.

Tip #5: Insulate Your Hot Water Pipes

This reduces heat loss in the pipes, so you get hot water to the faucet slightly faster, improving efficiency.

Tip #6: Know Your Groundwater Temperature

The colder your incoming water, the lower the maximum GPM your heater can produce at a given temperature. This is a key spec often overlooked.
