Why does the gas wall-hung boiler produce no hot water FAQ of the gas wall-hung boiler
Why does the gas wall-hung boiler produce no hot water
Point the operation button on the wall-hung boiler to the sanitary hot water gear, turn on the hot water faucet, cold water should flow out at this time, the fan should be heard running in front of the wall-hung boiler, and then there should be an electronic ignition At this time, the gas meter starts to run, the burner of the wall-hung boiler burns normally, and the sanitary hot water begins to flow out.
1. If there is no cold water flowing out, it means that the cold water valve has not been opened. Open the valve, but still no water flows out, it means that the pipeline is blocked or the faucet filter is blocked. The faucet can be cleaned by itself, but the blocked pipeline should be cleaned by a professional.
2. If there is cold water flowing out, but there is no sound of fan running, you should check whether the smoke outlet of the smoke pipe is blocked. If the smoke pipe is normal, a professional should check the air pressure switch, fan and related circuit faults .
3. If you hear the running sound of the fan, but there is no sparking sound, a professional should check the electronic ignition system and circuit board failure.
4. If you hear the sound of electronic ignition, but the indicator light of the gas wall-hung boiler is red, you should check whether the natural gas valve is open, and check whether the natural gas hose is bent or not.
Only the above 4 steps can easily solve the problem of no hot water in the gas wall-hung boiler.
Gas boilers FAQ
Why are domestic gas boilers safe?
Answer: Gas wall-hung boilers have been used in Europe for 60 years. The technology is very mature, and various safety protection measures are reliable to ensure safe operation.
Will the wall-hung boiler work continuously for 24 hours when heating in winter?
Answer: Basically not, the output power of the wall-hung boiler is selected according to the larger value of the sanitary hot water load. When designing, the heating load must consider a certain heating allowance, so at the design indoor temperature, the wall-hung boiler will automatically start and stop according to the set program without human intervention. If the boiler has been working at low power and does not stop, this When the house is in thermal equilibrium, the room temperature is stable and comfortable.
If the water pressure of the boiler drops frequently, it needs to be replenished frequently. Is there any harm?
Answer: In this case, there is a leak in the boiler or heating system. First of all, water leakage will cause property damage and discord between the upper and lower neighbors. Secondly, the possibility of scaling of the wall-hung boiler increases, which affects normal work and reduces the efficiency of use.
The boiler is frequently shut down due to the reduced water pressure of the heating system, and needs to be replenished frequently. How to deal with it?
Answer: Under normal circumstances, the water pressure in the system should not have a big change, that is, there will be no downtime. If it is often shut down, it means that there is a leak in the system, and professionals can be invited to inspect and repair the boiler and heating system.
Will scaling occur in the boiler heating system?
Answer: The heating system connected to the wall-hung boiler should be a closed system. The heating system can be used for a long time after one injection. It will adversely affect the boiler and heating system.
Do wall-hung boilers consume a lot of electricity?
Answer: The main power-consuming components of wall-hung boilers are fans and water pumps. The rated power consumption of wall-hung boilers is generally between 115-175W. Different models have different power consumption. .
Is the sanitary hot water and heating hot water in the wall-hung boiler a pipe?
Answer: The heating hot water and sanitary hot water in the wall-hung boiler have their own independent piping systems, and the two do not mix.
There are several operating modes for gas wall-hung boilers, how to choose?
Answer: The standard gas wall-hung boiler provides two operating modes: heating and sanitary hot water. There are two options for winter and summer on the control panel of the gas wall-hung boiler, which can be switched automatically.
In order to prevent freezing, can antifreeze be added to the wall-hung boiler and heating system?
Answer: As long as the antifreeze does not harm the boiler and heating system, it can be used.
What are the benefits of using a coaxial flue?
A: Save indoor space and improve combustion efficiency.
What is the function of the expansion tank in the boiler?
Answer: Absorb the expansion of the water in the closed heating system due to the increase in temperature, and keep the system pressure stable.
What types of gas can a gas wall-hung boiler use?
Answer: Natural gas, liquefied gas, components need to be replaced, artificial gas boiler can use artificial gas.
What are the safety protection devices for gas wall-hung boilers?
Answer: overheat protection, water shortage protection, combustion fault protection, system over-voltage protection, under-voltage protection, anti-system negative force too high, intake and exhaust safety protection, anti-freeze protection, water pump protection More than a dozen protective functions such as locking, gas power failure, gas cutoff, and low air pressure self-locking protection.
What factors determine the maximum allowable capacity of a gas boiler heating system?
Answer: The size of the effective volume of the expansion tank in the wall-hung boiler and the range of water temperature changes in the system determine the size of the maximum water capacity.
How to inhale fresh air and discharge flue gas when the gas wall-hung boiler is working?
Answer: When the gas wall-hung boiler is working, it inhales air through an independent intake pipe, and discharges the exhaust gas through an exhaust pipe, both of which are separated from the indoor air environment and are separated from the indoor air. Regardless of the environment, the operation is safe and reliable.
What functions can a gas wall-hung boiler provide?
Answer: Usually gas wall-hung boilers have two functions of heating and sanitary hot water. At the same time, some gas wall-hung boilers only have heating function, which we call single-function system wall-hung boilers (it can also provide sanitary hot water when connected to an external hot water storage tank).
