      What Are The Advantages And Disadvantages Of Westinghouse Tankless Water Heaters?

      Advantages of Westinghouse Tankless Water Heaters

      • Condensing Technology

      Condensing technology increases efficiency by utilizing the heat generated by the unit to contribute to heating the water. Using this heat means that the unit won’t need to work as hard, which you will notice in your gas bill. 

      Since the unit utilizes most of the heat from the burning of the fuel to heat the energy, it exits at a much cooler temperature. This gives you the ability to use standard plastic PVC piping to ventilate the excess gases, which are cheaper than the pipes needed for non-condensing units that must withstand significant heat. 

      • High-Quality Materials and Components

      Westinghouse makes a point to use high-quality materials in their tankless water heaters. They make the heat exchange out of high-quality stainless steel that holds up to corrosion, leaks, and damage better than the copper or aluminum typically used in the construction of water heaters, contributing to a longer life span. 

      • Easy Installation

      All Westinghouse tankless units allow for easy installation and come with all necessary accessories and a wall mount. Install residential units using your choice of direct vent or power vent (the commercial unit only comes in a direct vent design). 

      Disadvantages of Westinghouse Tankless Water Heaters

      • Lack of Selection

      Westinghouse made one tankless water heater with some slight variations, and it works extraordinarily well. However, many competing brands offer additional sizes and styles. Westinghouse does not yet offer an electric tankless option, non-condensing tankless option, or a point of use option. 

      • Cannot Convert Unit From Gas to Propane

      If you buy a natural gas tankless water heater from Westinghouse, you can not purchase a conversion kit to allow it to use propane like many other brands offer. Just be careful to select the correct fuel type when making your purchase. 

      • No WiFi or Bluetooth Technology

      Westinghouse does not offer WiFi or Bluetooth capabilities for their tankless units. People may want to use smart features to control the unit from their smartphone and monitor usage. 

      What Are The Key Features Of Westinghouse Tankless Water Heaters?

      Like most tankless water heaters, the Westinghouse tankless water heater provides some key features that make it a particularly attractive option: high efficiency, small size, and a longer life span. 

      High Efficiency: 

      Tankless water heaters run much more efficiently than conventional water heaters. Westinghouse tankless water heaters run efficiently and have an EnergyStar certification that can lead to $95 in savings per year compared to conventional gas water heaters.

      The ultra-low Nox emissions reduce nitrogen oxide levels due to its combustible control system. 

      Small Size:

      Conventional tank water heaters require a large amount of space. Tankless water heaters take up significantly less space and can fit in most areas in your home. 

      The ability to use both direct-vent and power-vent ventilation provides even more installation flexibility. 

      Long Life Span:

      Tankless water heaters don’t run as often allowing them to last 20 years, which is significantly longer than the 10 – 15 year life span of most tank-style water heaters. Tankless water heaters also have easily repaired components.

      Our Overall Review Of Westinghouse

      Reputable Company/Customer Service

      Westinghouse started with ambitious aspirations in 1886 that allowed them to create a number of innovative products. They continue to strive for greatness with an extremely large array of products. 

      Water heaters are only one of the products they make, but they ensure that every product maintains their strict standards. 

      Have a question? Call 774-417-6000 during regular business hours, and if you need troubleshooting help, select option 2.

      Manufacturing Process

      Westinghouse proudly states that their units are made in the United States of America. They also work hard to put the environment first by testing each water heater’s efficiency before it leaves the factory. 

      Ease of Use

      Westinghouse designs water heaters with easy installation in mind. They provide all accessories, including a wall mount. Once you install the unit, you will control it using a digital display on the device. The digital display also makes diagnostics easy with simple codes you can look up in the user manual. 

      Safety Concerns

      Westinghouse makes safety a top priority by including water heater safety features to prevent damage to the device and the user. 

      Some common safety features include:

      • Flame rod
      • Burner overheat cutoff device
      • Flue high limit switch
      • Water temperature high limit switch
      • Freeze protection
      • Water leak detection

      How Does Westinghouse Compare Against Competitors?

      You want a water heater with a reliable brand name. We will help give you some information on how Westinghouse holds up to the competition. 

      Westinghouse vs. Rinnai

      Westinghouse tankless water heaters don’t often come with the recirculation technology or smart features that many of the Rinnai tankless water heaters come with. 

      Rinnai also offers more tankless options than Westinghouse, but many of the options don’t provide the same efficiency levels. However, Westinghouse products last longer than Rinnai tankless water heaters and provide a better warranty. 

      Westinghouse vs. Rheem

      Rheem and Westinghouse both offer a wide range of products, but Rheem offers more tankless water heaters, including tankless electric water heaters and tankless point-of-use water heaters. 

      Both companies offer a similar warranty and have options with a stainless steel heat exchange. Many of the Rheem models also come with the EcoNet connectivity and recirculation technology. You can get adaptors to change the fuel type from natural gas to propane. 

      However, Westinghouse comes with higher efficiency than most Rheem models, and it can be used at higher altitudes.

      Our Westinghouse Tankless Water Heater Reviews

      Westinghouse offers one main tankless gas water heater product because they only need one. It comes in three models that have slight yet significant variations. 

      Some common qualities of all units are that they heat using condensing technology, offer propane and gas options, have a clear digital display, and come with a stainless steel heat exchange. 

      What sets the Westinghouse tankless water heater models apart? The main differences include maximum BTUs, water flow, efficiency, high temperature, and usage. 

      See our comparison of the three Westinghouse tankless water heater models, so you can pick the right one for you.

      It also has the unique capability to connect up to 8 additional hot water heaters with Cascade connectivity. This unit works great for small to medium commercial buildings.  

      Pros
