The article about tankless water heater parts explains the main components of the electric and gas water heating appliances that heat water on demand. We will cover the top manufacturers of on-demand models, including AO Smith, Rheem, Paloma, Rinnai, Bosch, Noritz, and others. An article about tankless water heater parts is to help you in your home DIY project such as troubleshooting, servicing, repairing and when replacing the broken parts.

As described before, in the article about, tankless technology allows water to be heated on demand and delivered instantly. This new and innovative technology works differently from the. The great advantage of tankless over tank type models is that majority of the parts are replaceable and recyclable.

And because of that, and to save money, it is good to know about each component, and how to replace it. Main tankless water heater parts • Heat exchanger • Gas valve • Burner • Ignition system • Combustion chamber • Combustion fan • Temperature sensors • Safety elements • Venting • Electronic system • Water valve • Remote controller Keep in mind that above tankless water heater parts are not all present on different brands and models; our goal is to cover a majority of the important elements found among different manufacturers. Heat exchanger The heat exchanger is a device, made of copper tube, or stainless steel, where a small quantity of water is stored – passing through, and used to transfer the heat from the gas burner. The heat is generated from the gas on the gas burner that is burning below the heat exchanger. In a case of the copper heat exchanger, the copper tube is combined with the copper fines, to increase the overall surface and increase the heat transfer. In electric water heaters, water is heated by a heating element (i.e.

Electric coils) which is turned ON by a flow activated switch. The advanced tankless water heaters, like Rinnai, have a commercial grade heat exchanger which is more durable and efficient.

Noritz has a superheat exchanger with a thicker piping for longer life and increased thermal efficiency. Condensing water heaters, due to the acidic nature of the condensate, are equipped with the stainless steel heat exchanger. In winter, when the heat exchanger is not used, cold water inside might freeze, especially when the cold air comes down through the vent pipe. This is why a minimum length of the vent pipe and combustion air is required. Due to the high mineral content in water, the heat exchanger may be scaled internally so the proper maintenance is necessary. Most of the manufacturers will provide a warranty on heat exchanger, which can be from 12 to 15 years while on other tankless water heater parts, the warranty is usually one year.

Combustion elements The combustion chamber is where the gas burns. A combustion chamber is designed as the room-sealed chamber (direct water heaters) and open (on atmospheric models).

Gas valves can be multi-stage and single-stage devices, with the modulation and ON/OFF option. Gas valves with the modulation are adjusting its power based on the water flow, demand and changes in any incoming and outgoing water temperatures; ON/OFF works with the maximum or no gas power only.

Combustion fan is positioned below the burner so the air can be rapidly mixed with the burning gas resulting in an increased efficiency. Burner elements The gas burner is usually installed below the heat exchanger, and on some commercial and condensing water heater models are made of high quality, stainless steel material, so it can work with higher heat outputs.
