How do gas water heaters remove limescale?

The cleaning method of scale in gas water heater is mainly to inject a special cleaning agent into the inside of the water heater, and then rinse it after soaking, and there is no need to disassemble the machine. The specific steps are as follows:

1. Prepare tools and materials.

Tools: taper, wrench, large syringe (or special injection tool), drain hose.

Material: Special cleaning agent for water heater (it is recommended to purchase food-grade citric acid cleaning agent).

2. Cut off the power supply, close the gas valve and water inlet valve.

After the tools and materials to be used are ready, unplug the power supply of the water heater, close the gas valve, close the water inlet valve, and ensure that the water heater is in a state of water cut-off, power-off and gas-off, so as to prevent it from starting during cleaning.

3. Drainage. Turn on the hot water shower or faucet to drain the water. And open the drain valve of the water inlet so that the water in the water heater is completely discharged.

It should be noted here that some water heater drain valves may be at the water outlet, some water inlets are a filter, and some are equipped with safety valves, no matter which one, as long as it is opened, air can enter and all the water in the water heater can be discharged.

4. Inject cleaning agent.

After draining the water from the water heater, we now need to inject the cleaning agent into the water heater. There are many ways to do this, but it is generally injected from the drain valve at the water inlet. It is possible to use a special door design for injection methods, to connect a small water pump, or to use the simplest large syringes.

The specific concentration of the cleaning agent is according to the instructions of the cleaning agent you bought, and some are in powder form and need to be diluted in advance.

When injecting cleaning agent, it is recommended to inject the hot water pipe with cleaning agent until the entire hot water system and the inside of the water heater are fully filled. It should also be noted here that the water heater is generally installed relatively high, and our faucet or shower is not as high as the water heater, and the incoming cleaning agent will flow out, and we must take corresponding measures to ensure that the cleaning agent does not flow out and is full of water heaters. There are many specific methods, such as putting the water pipe a little higher, closing the valve in time, and so on.

1. Remove the tap water inlet pipe of the water heater. Drain the water from the water heater.

2. Pour a weakly acidic liquid like white vinegar into the water heater from the inlet pipe.

3. Seal for about 3 hours, and then release it.

4. Remove the shower head and rinse the inside from the water inlet with tap water.

1. Drain and clean with water. Cut off the power supply, close the inlet valve, then open the outlet valve, and reverse the plastic drain ear on the safety valve 90 degrees counterclockwise to naturally drain the water and sediment in the water heater. Then fill the tap water to clean, after cleaning, and then return the drain ear to its original position, pay attention to fill it first before it can be energized.

2. Dilute hydrochloric acid cleaning. dilute concentrated hydrochloric acid into a low-concentration hydrochloric acid solution with water at a ratio of 1:3; Remove the water heater that needs to be cleaned of limescale and turn it upside down, so that the inlet and outlet of the water heater are facing up, and then pour in the prepared hydrochloric acid solution (the amount of solution poured should be flat to the inlet and outlet); After about half an hour, the hydrochloric acid reacts with limescale and dissolves, at this time, pour out the hydrochloric acid solution and rinse it with water.

3. Disassemble the water heater and remove it manually. The technical requirements are relatively high, so don't do it easily.

<> vinegar cleaning method: Mix white vinegar with water in a 1:1 ratio, and then pour the mixed solution into the water heater tank.

Allow the mixed solution to sit inside the water heater for a period of time (about an hour) to allow the acidity of the vinegar to dissolve and loosen the scale. Then open the outlet valve of the water heater and rinse the limescale and Hu Wei Peng vinegar residue thoroughly. Finally, rinse the water heater with clean water to ensure that the vinegar and limescale are completely removed.

Citric acid cleaning method: Citric acid is also an effective way to remove limescale. Mix citric acid with water in the appropriate proportion, then follow the steps of the vinegar cleaning method, pour the citric acid solution into the water heater tank, leave it for a while and rinse it off.

Commercial cleaners: There are also some commercial cleaners on the Yamagataka market that are specifically designed to clean water heaters, and you can follow the instructions for using the detergent. Be careful to choose the right cleaner for your water heater model and material, and follow the instructions for use and safe operation.
