Westinghouse APOLO Performance Tankless Water Heater Review: Endless Hot Water for Your Home!

Hey everyone in the group! 👋 I know a lot of you have been asking about ways to upgrade your home’s efficiency and comfort, especially when it comes to those everyday essentials. Well, I’ve had the chance to dive deep into a product that’s been on many of our radars: the Westinghouse Natural Gas Tankless Water Heater, APOLO Performance model. And let me tell you, after putting it through its paces (figuratively, of course, as a reviewer!), I’m excited to share my honest thoughts.

We all know the dread of a cold shower, or running out of hot water when you’re trying to do laundry and wash dishes simultaneously. That’s where a tankless system like this one promises to shine. It’s designed to give you hot water on demand, without the bulky tank taking up space in your utility closet.

Overview: Say Goodbye to Cold Showers!

The Westinghouse Natural Gas Tankless Water Heater is an indoor-installation unit designed for whole-home use. What does ‘tankless’ mean for you? It means no more storing dozens of gallons of hot water that slowly cool down, wasting energy. Instead, this unit heats water only when you need it, as it flows through the system. It’s a modern solution aimed at providing a continuous supply of hot water while potentially saving you money on energy bills in the long run.

This particular model, part of their APOLO Performance line, boasts a maximum flow rate of 5.1 GPM (gallons per minute) and a powerful 120,000 BTU heating capacity. For those of us who appreciate smart home tech, it also comes with WiFi capability for temperature control and monitoring, which is a huge plus!

Our community has often discussed the benefits of going tankless, and this Westinghouse model seems to hit many of the key points. It’s designed for high efficiency and is non-condensing, which simplifies installation compared to some other high-efficiency models. Let’s dig into what makes this unit stand out.

Key Features & Specs That Matter

When you’re looking at a big home appliance like a water heater, the details really count. Here’s a breakdown of the Westinghouse APOLO Performance model’s standout features:

• Natural Gas Fuel Source: This unit is specifically designed to run on natural gas, which is often a more cost-effective and efficient fuel source for water heating in many areas compared to electricity. If your home already has a natural gas line, this is a straightforward option.
• Tankless Design for On-Demand Hot Water: This is the core benefit! Instead of a large tank, this compact unit heats water instantaneously as it passes through. This means you get an endless supply of hot water as long as your gas and water supply are consistent. No more waiting for the tank to refill after someone else takes a long shower.
• Indoor Installation: The APOLO Performance model is built for indoor use, which typically offers better protection from the elements and can contribute to a longer lifespan. Proper venting is crucial for indoor gas appliances, so factor that into your installation plans.
• Max 5.1 GPM (Gallons Per Minute): This flow rate is significant. For context, a typical shower head uses about 2.5 GPM, and a kitchen faucet around 1.5-2 GPM. A 5.1 GPM capacity means this unit can comfortably handle two simultaneous hot water demands, like two showers running at once, or a shower and a dishwasher. For smaller to medium-sized families, this is usually more than adequate for whole-home use.
• 120,000 BTU Heating Power: BTU (British Thermal Units) measures the heating power. 120,000 BTU is a robust capacity for a tankless unit of this GPM, ensuring it can quickly heat water to your desired temperature, even when the incoming groundwater is very cold (which is a common concern with tankless systems in colder climates).
• WIFI Enabled Temperature Self Modulating: This is where the smart home aspect comes in! The WiFi feature allows you to control and monitor your water heater’s temperature settings from your smartphone. The ‘self-modulating’ aspect means the unit automatically adjusts its flame output based on the hot water demand, preventing temperature fluctuations and optimizing fuel consumption. It’s a set-it-and-forget-it kind of convenience.
• Non-Condensing High Efficiency: This refers to the heat exchanger technology. Non-condensing units typically vent directly to the outside without needing a drain for condensate, simplifying installation and potentially reducing costs compared to condensing models, while still offering good efficiency. It’s a balance of performance and ease of setup.
• Designed for Whole Home Use: As mentioned, with 5.1 GPM and 120,000 BTU, this unit is marketed and capable of supplying hot water for an entire household, assuming typical usage patterns.
• APOLO Performance Series: This designation indicates it’s part of Westinghouse’s line focused on reliable performance and efficiency.

Pros & Cons: A Balanced Look

No product is perfect for everyone, and it’s important to look at both the good and the areas where you might need to make considerations. Here’s what I’ve gathered:

👍 The Pros (What We Love!)

• Endless Hot Water: This is probably the biggest draw! Our group often talks about the frustration of running out of hot water. With this tankless system, as long as it’s correctly sized for your home, you’ll have hot water whenever you need it, for as long as you need it.
• Energy Efficiency: By only heating water on demand, this unit avoids the standby heat loss associated with traditional tank water heaters. This can lead to noticeable savings on your natural gas bill over time. The self-modulating feature further enhances this efficiency.
• Space Saving: Tankless units are significantly smaller than their tank counterparts. This frees up valuable floor space in your utility closet, basement, or garage. I’ve seen some amazing before-and-after photos in our group where people reclaimed so much space!
• WiFi Connectivity: Being able to adjust temperature settings or monitor the unit from your phone is a fantastic modern convenience. Imagine turning up the heat before you even get home from work!
• Longer Lifespan: Tankless water heaters generally have a longer lifespan (15-20 years) compared to traditional tank heaters (10-15 years), especially with proper maintenance.
• Consistent Temperature: The self-modulating technology helps ensure a stable hot water temperature, preventing those annoying cold bursts mid-shower.

👎 The Cons (Things to Consider)

• Higher Upfront Cost: Tankless units, including this Westinghouse model, typically have a higher initial purchase price than traditional tank water heaters. This is an investment that pays off over time through energy savings and longevity, but it’s a factor for your budget.
• Installation Complexity & Cost: While this is a non-condensing unit (which can be simpler than condensing), converting from a tank to tankless often requires professional installation. You might need upgrades to your gas line, venting system, or even electrical wiring, which adds to the overall cost. It’s not usually a DIY project for most homeowners.
• Flow Rate Limitations (for very large families): While 5.1 GPM is great for most homes, if you have a very large family that frequently needs three or more hot water demands simultaneously (e.g., three showers, or two showers and a dishwasher/laundry running at the same time), you *might* experience a slight drop in temperature or flow. It’s crucial to assess your peak hot water usage.
• Small Delay for Hot Water: Unlike a tank heater where hot water is always ready at the faucet, there’s a very slight delay (a few seconds) as the water travels from the unit to your tap and heats up. Most people find this negligible, but it’s worth noting.
• Maintenance Requirements: Tankless units require annual flushing to prevent mineral buildup, especially in areas with hard water. This is a crucial step to maintain efficiency and extend the unit’s lifespan.

Who Is The Westinghouse APOLO Tankless Water Heater For?

Based on its features and performance, I’d say this unit is an excellent fit for:
