Explaining Tubular Heat Exchanger

Alright, everyone, in this section, we’re going to delve into the world of tubular-style heat exchangers. Specifically, we’ll focus on a model known as the Rheem Criterion, although it’s worth noting that Rudd produces an identical heater under a different name. This particular heater has generated millions in sales for me, largely due to its flawed design. From its inception, it was evident that the design was not well thought out, and yet, this model continued to be produced for a considerable time. Whenever you encounter a Rheem or Rudd unit that’s over 8 to 10 years old, I strongly advise inspecting the heat exchanger closely.

It’s a straightforward process. We’ll provide additional videos in the app to guide you through removing it. You’ll find it requires removing just about six screws from the front to extract the entire heat exchanger. Now, when examining this type of heat exchanger, there are several common failure points to be aware of. Let’s break down the engineering concept behind it. Flames are directed inside the tube to heat everything up, leading into a large tube that feeds into what’s called an accumulator. This accumulator captures and then distributes the heat through smaller tubes, transitioning from a large tube to smaller ones. The intention behind this design was to enhance efficiency by slowing the heat’s movement, thereby reducing the gas needed to warm the home. However, the original engineering team overlooked the excessive heat buildup in this area.

In these heaters, the heat transitions from the accumulator to the small tubes, leading to overheating. These tubes are connected to the accumulator with a flare fitting, which tightens as the temperature rises. According to the Heat Exchanger Expert book, even the slightest movement of this heater can indicate a potential failure. Other common failure points include cracks at the back of the accumulator due to extreme heat and within the tubes themselves. The insertion of a NOx rod within these tubes, aimed at slowing heat transfer for greater efficiency, was a retrofit not originally planned for. These rods, being additional metal pieces, become extremely hot and often lead to failure.

Notably, if you discover a crack, it’s imperative to turn off the gas immediately and inform the customer of their options: either replace the heat exchanger or the entire furnace. In cases where the furnace is in such condition, I advocate for a complete replacement rather than merely changing the heat exchanger. It’s crucial to communicate the severity of the issue to the customer and consider a redesign for proper functionality. Throughout its lifecycle, this heater likely never operated efficiently; it was always loud and struggled with temperature regulation.

This heater has significantly contributed to my sales success, and I recommend that if you encounter it, thoroughly inspect it to ensure your customers’ safety. I’m particularly proud of a technician on my team who identified a faulty unit and potentially saved a family from carbon monoxide exposure or a fire hazard. I hope this video proves useful and aids you in securing more sales by prioritizing safety and efficiency in your offerings.
