How to choose the operating mode Many boiler brand operating modes generally have two kinds of heating and sanitary hot water. In the gas boiler control panel, there will be two options for winter/summer. If it is in winter, users need to use both domestic heating and hot water, then set the boiler in the winter gear and choose the heating mode when heating. Select hot water mode when using hot water. If the user only needs to use domestic hot water when he does not need heating, the boiler can be set in the summer gear and the mode can be selected in the hot water mode so that the sanitary hot water function can be used.
How to control the temperature The gas boiler control board has the temperature adjustment. The hot water temperature adjustment file and the heating temperature control file can be adjusted according to the need.
When no one is operating, many office workers are unattended during the day. In order to save the use of natural gas in the boiler, they feel that the wall-mounted heating stove will be turned off to save gas. After work, the wall-mounted heating furnace will be placed in a high-end and heated rapidly. This is actually a practice. Very unscientific. When wall-hung boilers start, due to the large temperature difference between the room temperature and the set temperature of the wall-mounted heating stoves, wall-hung heating stoves need time to run on fire, which not only does not save energy, but will also waste more gas and increase the time for residents to freeze. The right thing to do is to lower the temperature of the boiler so that it can maintain the temperature in the home and it can also achieve the effect of solar power.
How to prevent the boiler from being frozen in some places In winter, the temperature is low in some places. How to prevent the boiler from being frozen, if there is no person in the house during the day, the boiler must be provided with anti-freeze, sufficient electricity and gas, in order to avoid radiator and wall heating. Furnace water pumps, heat exchangers and other components are frozen, various brands of heating boilers are equipped with anti-freeze function, the specific operation method, please refer to the instructions.
If you can properly use and operate the boiler, this can reduce the damage rate of the boiler, it can also ensure the safety of the system, extend the service life of the boiler.
Across the pond, you will find the Deutsches Institute fur Normung (DIN) flange specification, consisting of a variety of European styles which have been unified into one code for the purpose of commonality. Designation as a DIN Flange by the German Institute of Standardization assures the user of design quality the way an ASME flange would here in America. Although much less common than ANSI/ASME steel flanges in the United States, many of our international customers request flanges to these specifications for a variety of applications such as imported steel vessels, cargo ships, and other infrastructure which may consist of metric pipes/valves and European designed equipment.
The subset flanges under the DIN standard consist of the same style of flanges in the United States, including the most commonly used slip on flanges, weld neck, flanges, and blind flanges. Adapter flanges can be custom made to end user requirements for the mating of American flanges to international ones, however we find it is a much more common and easy solution to provide DIN flanges to mate to existing equipment.
The most common metric type flanges fall under the following categories:
DIN 2501 through 2503 for flat ring flanges
DIN 2512 through 2519 for alternate face flanges
DIN 2627 through 2633 for weld neck flanges
DIN 2641 through 2642 for lap joint flanges
DIN 2565 through 2569 for threaded/companion flanges
DIN 2527 for blind flanges
