This is a normal phenomenon in a closed water pipeline in thermal expansion , the pressure will rise naturally , piping water greater capacity ( the bigger room ) the greater the swelling pressure , the higher the temperature setting , the greater the swelling pressure However, when cooled to room temperature, the pressure should be restored to 1.2-1.5bar.

After the pressure of the cooling water is lower than the pressure of the original charge .

This is normal , there is an automatic boiler running wind ( exhaust valve ) , the heating operation , piping and heating the film in air , water will be brought to the furnace exhaust valve , the air is automatically discharged , the pressure after cooling , than the original pressure of the water filling is reduced. After several emissions and pay only after the air in the pipe to drain . Note , do not run, if the pressure is still reduced, there may be a drip phenomenon, need for investigation .

Do not worry, whether imported or domestically have three minutes delay and cool down delay function in the program, that is to say , after reaching the set temperature, two conditions must be met , the boiler can be restarted : ① time has shut down more than 3 minutes ; ② temperature lower than 5 ℃, and the two conditions must be satisfied in order to restart.

After installing the thermostat, knob or button on what role the boiler .

Adjust the thermostat to control the temperature , while the number of degrees to heat the water at room temperature , or the need to control knob on the boiler . For example : The temperature on the 9 button on the boiler , thermostat adjustment knob at 20 ℃, 85 ℃ then hot water boiler will be heated , so that as soon as the room temperature reaches 20 ℃ . If the temperature on the 0 button on the boiler , set at room temperature for 20 ℃, 30 ℃ to the boiler for heating water . Obviously , the former indoor heating speed, room temperature which slowly . Therefore, we can say that installed the thermostat, the furnace

Original furnace display umbrella , summer mode , which is only for sanitary hot water . Show Snowman said winter mode , heating and sanitary hot water two functions are available. Antifreeze is set to display umbrella , that only hot water mode , when the boiler is not running , when the water temperature is below 4 ℃, the boiler will automatically start to burn 42 ℃ water and so forth ( be sure to turn on the gas , electricity ) . If you set the mode to "The Snowman " , was running low , not antifreeze . Antifreeze made ​​more detailed : Function button set hot file , as long as powered ventilation, when the water temperature is less 9 ℃ when the pump starts to strengthen water cycle , if the temperature continues to decrease to 5 ℃, 30 ℃ auto-ignition temperature to stop The other two buttons randomly placed . We might try to open the balcony windows . And in the off state , as long as electricity, ventilation, at 5 ℃, will be forced to start in order to protect the boiler .

Short run , does not explain is the charge or not charge. Only makes sense to mean the entire heating season . Heating boiler must undergo the following procedures : ① barn ; ② absorbing walls and space heating ; ③ thermal equilibrium , namely heat and boiler heat loss is equal to the supply room . ①, ② program is the most expensive gas in the process . ③ is the most economical process gas . In the heating process after entering the normal state of ③ . Therefore, the method is not the most throttle off the furnace , but when not heating the temperature to the low-grade, and then raise the temperature of the heating needed to reduce the program ①, ② repetition. 100 square meters , for example, a heating season average ( including bathing , cooking ) 6-8 cubic meters of gas daily consumption .

How do I know the insulation condition of the room .

For example, a heated indoor 18 ℃, indoor fixed a thermometer. Off oven 12 hours ( during the day ) after the thermometer reduced 1-2 ℃, the night reduced 4-5 ℃, description insulation is good, otherwise

Where there is air leakage , need to be carefully checked.

Solve cold water bath before .

First calculate the amount of water wasted , 8-15 seconds before the bath of cold water has been heated by the outflow that is 0.16 l / s × 15 = 2.4 liters, open daily 10 times for 24 liters waste water a year to 8760 liters or 9 cubic 30 yuan. Saving approach : ① with pots pick another he used to do . ② sanitary hot water boiler minimum starting flow of 2.5 l / min , the use of sanitary hot water , the first to open a small flow of hot water immediately after when open big . Simple judgment 2.5 l / min flow rate of the faucet is opened to form hair pen thickness of the water column can be. ③ the most advanced method : Using old electric water heater and boiler coordination center with integral hot water tank , this method is ideal for the bathroom distant units. Use of sanitary water heating boiler and water heater pass into the inlet . Electric water heaters heat only assume the role . For example boiler burning 80 liters of hot water consumption of 0.36 cubic meters of gas , the cost of 0.68 yuan . Electric water heater 80 liters , holding 24 small power consumption of 1.5 degrees , and gas costs the same , continuous use , less waste and more comfortable.

Boiler flue security.

Smoke tube boiler double concentric tube, the exhaust tube , the outer tube into the air, and communicating with the seal chamber , with the interior is completely isolated . All brands are the mandatory boiler exhaust ( fan ) Balanced (with pressure switch ) , so the exhaust and intake air are outdoors , do not consume the indoor air , security is guaranteed . The explosion occurred in recent years , is due to the natural gas hose leak , there were no reports of the bombing of the stove .

Sanitary hot water boiler becomes smaller reasons. Blocked or cold water faucet filter water inlet filter blocked . Remove the cold water inlet bellows can see. Can be restored after cleaning .

Heating boiler with noise and heat slowly.

May be heating boiler back into the inlet filter blocked , can, or heating pipe bellows stuck open after cleaning .

When cleaning the filter how drainage.

Furnace heating water discharge method. Turn off the cold water inlet valve, fill valve open , open sanitary hot water faucet , furnace heating water can be discharged. Reverse operation can be re- filled with water running . Unscrew can. Drain the radiator , the radiator can only use the run the wind .

Dress boiler radiator height of more than often have running water sound .

In the long run the wind deflated several times at the radiator , and the boiler filled with water , can be repeated several times .

Room falters reasons are the following :

Heat radiator is not enough , this failure can easily occur in the home user to replace the radiator . The large radiator piecemeal , so that the heat radiator is insufficient to cover the heat loss of the room .

Wet room is dry , because the wall is wet , the moisture content and the need to absorb a lot of heat vaporization , so at room temperature do not increase, the barn about a week's time .

Open the stop , did not reach equilibrium at room temperature , that is shut down, but also because of the heat early inter- household transfer heat is absorbed by the outside world , so the temperature is always below standard .

Down about not heating, heat loss.

New home for the first time using the boiler, the more appropriate method is:

After heating power button located at zero temperature profile at the lowest temperature heating, and do not shut down, so as not to slow the barn walls, furniture dry.

Do not open to a higher temperature , a wall is not conducive to evaporation of water vapor , the second is due to the heat transfer between the household and neighbors to help fend off the cold , thankless gas costs , the third is either re- open the high temperature does not help, but shorten the time barn temporarily warm room or stagnant. With the lowest temperature , about a week after use , you can freely warming. Low temperature of about 3-4M3 gas plus daily bathing , cooking 5M3 enough . ( Due to water vaporization needed more calories , so the barn is more cost gas ) .

The reason is that the problem of the four new homes at check each cell must be facing one need not worry , two do not have to hurry, then the situation will improve day , the temperature will be rising.

Original boiler fault causes and repair 28 :

28 The meaning is: When heating boiler , there is the phenomenon of sanitary hot water flow . Set this function Cause: heating, water temperature is higher, in the heat exchanger tubes and sanitary hot water heating pipes are tied , so the hot water temperature is higher, if the sanitary hot water outflow will exceed 60 ℃, to prevent the occurrence of burns , the heating must not drop below 2.5 l / min outflow of hot sanitary water , but greater than 2.5 l / min , can be converted to a hot water heating . Failure to produce points : ① water point user taps sanitary hot water pipe lines , etc., there are leaking. ② sanitary hot water flow switch has impurities affect the normal flow signal indication . ③ sanitary hot water thermistor is faulty. Fault diagnosis method : tap off after the inlet valve , the normal heating. If 28 does not appear, as evidenced by the boiler to each faucet plumbing , water leakage phenomenon, your own search. If you turn off the water inlet valve , the normal heating . Then 28 is still there , compared ②, ③ failure , flushing flow switch or replace thermistor to ( need maintenance personnel ) . When the water point ( tap ) water from the boiler outlet more than one meter , this feature can be deleted without .

User and maintenance personnel should pay attention to . This is mostly the fault of sanitary hot water from the boiler outlet to the leaky pipeline between the tap (including taps ) are insufficient to start leaking boiler ( 2.5 l / min or less ) , not heating water leakage, regardless of the pressure gauge .

Purpose: To ensure the normal operation stove , the stove after a period of operation , maintenance should be carried out . Maintenance cycle depends on the stove work environment, the use of temperament , usually given once a year to maintain and clean....
