    1. Interpretation of the internal structure of a gas water heater.

    As a consumer, you may not be as professional as we are, so here is a simple selection of a few more important parts and components for everyone to learn. They are: heat exchanger, combustion chamber, fan, gas proportional valve, water flow sensor, smoke exhaust pipe, water inlet pipe, drain pipe and so on.

    2. Heat exchanger

    After dismantling the gas water heater, the larger piece and occupying the C position is the heat exchanger, also known as the water tank. The water tank is one of the core components of the gas water heater. Once the water tank is broken, the entire water heater is equivalent to scrap. At present, the materials of heat-burning water tanks are roughly divided into copper-containing water tanks and stainless steel water tanks. Stainless steel water tanks are only used by the Smith family. Since there are too few sample companies, no evaluation will be made. The copper-containing water tanks used by mainstream manufacturers are mainly divided into oxygen-free copper, phosphorous deoxidized copper, oxygen-free copper, etc. What is the difference? We assume that the post-processing process is different, and everything else is the same.

    3. Burner

    Also known as the combustion chamber, generally the fire blast must be in contact with oxygen to the greatest extent, so as to achieve the goal of full combustion. General shapes are V-shaped and U-shaped. You don’t need to care too much about the shape. You can’t see it anyway. The material is also divided into 304 stainless steel (food grade) and 430 stainless steel (industrial grade), the difference is basically not big. In fact, whether it is two-stage combustion or three-stage combustion, they are collectively referred to as intelligent segmented combustion. Priority is given to three-stage combustion so that the water temperature will be more comfortable.

    4. Gas proportional valve

    As the same core component of the water heater, the constant temperature largely depends on it. A high-quality gas proportional valve can adjust the ultra-fine within 10pa The change in airflow is equivalent to a pressure change of 100pa when you open your mouth and blow a breath. Many fuel heaters on the market claim to be "water-gas dual-regulation" or "water volume server". In fact, they have added memory alloy or water volume server based on the original gas proportional valve. Finally achieve the effect of constant temperature.


    Description of water heater, heater, gas water heater tankless:

    - Gas type: Natural gas or LPG

    - Gas pressure: 20 mbar / 28-30mbar

    - Power: 24 KW

    - Nominal Output power: 21 kW

    - Connection: 220-240 Volt

    - Max. power consumption: 45 Watt

    - Size: 380x630x160 mm

    - Minimum water pressure: 0,2 bar

    - Maximum water pressure: 8 bar

    - Water flow: between 3 and 12 liters per minute

    - Temperature range: 35 to 65 degrees

    - Connection flue gas discharge: 60/100 mm

    - Weight: 13.5 kg.

    - Power cord with plug included

    This is the safest type of gas water heaters available in the market. The fresh air inlet comes from outside and the exhaust gasses are pushed outside. This makes it possible to mount the water heater in any (bath-) room without restrictions.

    The temperature is controlled by thermostats. Automatic safety controls are fitted to the water heater to provide safe and efficient operation.
