Wall-hung boiler uses 28 tips

1. Is the power consumption of the wall-hung boiler large?

The main electrical components of the wall-hung boiler are exhaust fans and circulating water pumps. The rated power consumption of the wall-hung boilers is generally between 100 and 200W. The power consumption of different products is different. You can refer to the product manuals of each product in detail.

2. Is it dangerous to use a gas boiler at home?

The gas fireplace has been used in Europe for 40 years and the technology is very mature. The security protection measures of the device configuration are quite perfect, and users can use it with confidence.

3. Will fouling occur in the boiler heating system?

In the case of ensuring that the heating system is well sealed, the amount of water initially injected by the heating system is constant, and the scale generated is minimal and does not pose a danger to the heating system.

4. Is the sanitary hot water and heating hot water in the fireplace connected?

The heating and hot water in the wall-hung boiler have their own independent piping system, and the two do not mix.

5. In order to prevent the wall-hung boiler from freezing when no one is in the winter, can you add antifreeze to the wall-hung boiler system?

No chemicals can be added to the wall-hung boiler system, especially anti-freeze.

The correct antifreeze measures should be:

1) When there is no one in the home for a short time (within one week), the temperature of the wall-hung boiler can be set to the lowest, and the fireplace will run at the lowest temperature.

2) When there is no one in the family for a long time, all the water in the fireplace and heating system can be drained clean. However, it should be noted that before the operation, please fully consider other pipelines in the room, such as the water pipe selected from the water will never freeze. Please do not close the fireplace and keep it running at a low temperature.

6. What are the benefits of using a coaxial flue?

Save indoor space and improve combustion efficiency.

7. What is the role of the expansion tank in the fireplace?

Absorbs the amount of expansion of the water in the closed system due to temperature changes, keeping the system pressure stable.

8. What are the safety protection devices for gas fireplaces?

Overheat protection, water shortage protection, combustion fault protection, system overpressure protection, exhaust air safety protection, gas shortage protection, antifreeze protection, anti-locking of water pump, power failure, self-locking protection of gas and other dozens of protection functions.

9. What factors determine the maximum water capacity allowed by the gas boiler heating system?

The effective volume of the expansion tank in the wall-mounted furnace determines the amount of water capacity allowed in the system.

10. How to extract fresh air and emit combustion fumes when working on gas boilers?

When the gas boiler is in operation, the air and the exhaust gas are respectively taken through the independent intake pipe and the exhaust pipe. Both are independent of indoor air and operate safely and reliably.

11. Can a three-story villa use a gas fireplace?

In the closed system required for the wall-mounted furnace, the system pressure is between 1 and 2 bar. The built-in circulating water pump of the wall-hung boiler only needs to overcome the resistance of the system cycle. Therefore, as long as the resistance of the system is designed, the system resistance will be provided in the product manual. The wall-mounted boiler can be directly used within the allowable range of the off-board flow-head curve. Otherwise, the external circulating water pump can be installed with reference to the technical data provided by the equipment manufacturer. (Under the premise that the rated output power of the boiler meets the heating load of the villa)

12. When heating in winter, will the wall-hung boiler work continuously for 24 hours?

Basically, the output power of the wall-hung boiler is selected according to the larger value of the sanitary hot water load and the heating load. Usually the household's sanitary hot water load is greater than the heating heat load, so in the design indoor temperature, the wall-hung boiler will automatically start and stop according to the setting procedure, without human intervention.

13. What are the benefits of using a gas fireplace?

1) The water output is large. A 24Kw wall-hung boiler has a water production capacity of 13L/min when the temperature difference between tap water and hot water is 25°C, which can basically satisfy the use of a high-end shower and a hand washing faucet.

2) The temperature of the hot water is stable. The temperature probe in the wall-hung boiler monitors the hot water temperature at all times. When the water consumption changes, adjust the output power of the boiler (adjustment range 30%-100%) to keep the hot water outlet temperature stable.

14. How to reduce the gas consumption of the fireplace?

1) When purchasing a house, fully consider the factors that affect the heat consumption of the room, such as: enclosure structure, orientation, floor, etc., try to buy a room with low heat consumption in the room;

2) Users should set different temperatures according to the working habits of family members in different time periods of one day/week (can be completed by configuring a room temperature controller with programming function) to avoid the presence of no one in the home. Still running at high temperatures.

3) Regular maintenance, so that the wall-hung boiler is always in an efficient state.

15. What are the factors affecting the gas consumption of gas boiler heating?

The air consumption of the wall-mounted heating furnace is not absolutely related to the equipment itself, but mainly by the following factors:

1) indoor set temperature;

2) outdoor climatic conditions;

3) ventilation and ventilation;

4) the impact of the floor;

5) occupancy rate around the room;

6) User usage.

16. What are the advantages of choosing a gas fireplace?

1) Users each self-contained system, while solving heating and hot water supply problems.

2) Single-family gas wall-hung boiler heating has great adjustment flexibility, the use is completely independent, the heating temperature can be adjusted independently, the heating time can be controlled by itself, the temperature of each room can be controlled freely, and there is no heat loss in the boiler room and the external heat network. Save on investment in external network construction.

3) In line with the principle of charging according to heat, the gas consumption can be accurately measured, and the gas consumption can be controlled by the user to save gas.

4) The heating cycle has low power consumption, saves energy, and improves the utilization and economic benefits of gas pipelines.

17. What are the main components of the European standard gas boiler?

It is mainly composed of four parts: gas combustion system, heating circulation system, domestic hot water circulation system, and safety protection control system.

18. What are the common matching methods for gas fireplaces and heat sinks?

The gas boiler can be matched with the radiator system, the floor radiation system, the fan coil system and the like. (Note: When designing the system, be sure to check the flow and resistance characteristics of the system and choose the correct matching solution)

19. Can gas-fired boilers provide both heating and sanitary hot water?

The European standard gas boiler heating and sanitary hot water mode can not be operated at the same time, the sanitary hot water function is preferred, and the gas fireplace is automatically switched between the two according to the use of sanitary hot water.

20, gas fireplaces have several operating modes, how to choose?

The standard gas fireplace provides two modes of operation: heating and sanitary hot water. There are two options for winter/summer on the control panel of the gas boiler. In the winter stall, the gas boiler can provide heating and sanitary hot water function. The sanitary hot water function is preferred, so the gas boiler is used according to the user's sanitary hot water. In the heating and sanitary heat mode, the situation is automatically switched; in the summer gear position, the gas boiler is usually in standby state, and only when the user uses the sanitary hot water, the utility model enters the sanitary hot water mode. Therefore, the user can select the winter gear when heating is needed in winter and when using sanitary hot water, and the summer gear can be selected for the rest of the time, and only the sanitary hot water function is used.

21, what functions can be provided by gas fireplaces?

Generally, gas fireplaces have both heating and sanitary hot water functions.

At the same time, some gas fireplaces only have heating function. We call it a single-function system fireplace (which can also provide sanitary hot water when connected to an external hot water storage tank).

22. What types of gas can be used in gas fireplaces?

Natural gas, liquefied gas, and some special models can also use artificial gas.

23, I have to leave home for a while, this is winter, will my heating stove and system freeze?

By adjusting the heating thermostat to the "lowest" position, you can prevent your heating furnace and system components from freezing (provided that the door of each radiator must be opened). For long-term uninhabited houses, it is recommended to completely remove the water from the entire heating system; or to protect the heating furnace and system by asking the manufacturer for specific frost protection measures. Note: The simple domestic hot water ring does not protect your heating stove.

24, my heating furnace stopped working, a red light is flashing, and the water pressure indicator is also flashing.

Your heating stove has realized that there is a lack of water in the system. You must fill the water with a water injection knob located at the bottom of the heating furnace to bring the water between 1-2 bar. After this operation, your heating stove will automatically ignite. If you need to fill the water frequently, it is likely to be caused by a leak in the system. After this happens, you must contact your supplier.

25, I often hear the sound of running water in the radiator of my house.

This may be caused by air remaining in the water pipe or radiator. You can use the windshield that opens the top of the heat sink to let the air out. After that, you must adjust the water pressure in the heating furnace and ensure that the pressure is stable. This can be done by the drain knob below the heating furnace.

26, in the shower, I have to wait a long time to get hot water!

Regardless of the working condition of your heating stove or the volume of your storage tank, the amount of hot water is determined by the amount of cold water remaining in the water pipe. If your bathroom is 10 meters away from your storage tank (or heating stove), it will take a long time to wait for a few seconds of hot water.

27, since the installation of the indoor thermostat, the radiator is cool all afternoon!

This is the benefit of using a thermostat. When the afternoon sun is good, the thermostat will stop the heating stove, and sufficient light will keep your room at a comfortable temperature.

28, sometimes, when I turn the hot water tap to the maximum, the water temperature seems to be lower, is this the case?

Yes. For an instantaneous secondary plate-type heating furnace, the temperature of the domestic hot water depends on the flow rate of the water. The faster the water flow, the worse the heating function of the secondary plate changer to water. When this happens, you can increase the water temperature by reducing the flow of water.

This machine is suitable for Glass, Metal, Paper, Plastic etc.

It is widely used in fields that have high requirement on depth, smoothness and fine, such as clock and watch, mould, bitmap marking, etc. And used in industries like electric component, gift, communication equipment, electric appliance, construction material, package of food and medicine, PVC materials, IC integrate circuit, communication equipment, craftwork, polymethacrylate, semiconductor etc.

2) The whole system's function is stable, low consumption.
