If your chimney flue is cool enough, water will condense inside, and then evaporate via steam when the boiler fires. You may also have water coming in from rain, and may want to purchase a chimney cap to prevent water from getting in.
Closing the air vent valve when white steam is coming out of a boiler is essential to maintain proper pressure and ensure efficient operation. White steam indicates that water is vaporizing, and if air is allowed to escape, it can lead to pressure fluctuations and inefficient heating. By closing the valve, you help to create a sealed environment that promotes optimal steam production and prevents air from interfering with the heating process. Additionally, this practice helps to prevent potential safety hazards associated with uncontrolled steam release.
If there is no hot water coming from the taps and no pressure in a combi boiler, it could be due to several issues. A common reason is low water pressure, which may be caused by a leak in the system or a faulty pressure relief valve. Additionally, the boiler could be in lockout mode due to overheating or a fault, preventing it from heating water. Checking the pressure gauge and ensuring it’s within the recommended range, along with inspecting for leaks, can help diagnose the problem.
Depends on the situation! It may be needed at only a low pressure. Otherwise it may be the result of reduced heat input or of the input of cold feed-water.
Basically . economiser is located in between exit of boiler and entry of air preheater. when the flue gases are coming out from boiler they take away a lot of heat. economiser utilize this heat from flue gases. and these heat is used to heat the feed water which is going to feed the bolier. hence by using economiser the coal consumption required to heat the feed water is reduced hence cost reduced.
The feed check valve of a boiler is on the line coming out of the boiler it is usually to prevent the water from going back in to the boiler its coming out of so it would build up excessive amounts of pressure which will cause the t&p valve to blow temperature and pressure
needs to be cleaned
*A boiler check valve is usually made by Watts and called a Watts 9D. This prevents the water that goes into the boiler backflowing and having the heating water from the boiler coming back into the domestic water and having you drink it or shower in it.* Cheers,QuiteSomething
To detect a tube leak in a fire tube boiler, you can look for signs such as increased fuel consumption, reduced boiler efficiency, visible steam or water leakage from the tube, or unusual noises coming from the boiler. You may also conduct non-destructive testing methods like ultrasonic testing or using a thermal imaging camera to pinpoint the location of the leak. Regular inspection and maintenance are crucial to prevent and address tube leaks promptly.

Common signs of a boiler leak include water pooling around the unit, a drop in boiler pressure, unusual noises coming from the system, and visible corrosion or rust. Potential risks of a boiler leak include water damage to the surrounding area, reduced efficiency of the boiler, and the possibility of carbon monoxide leaks if the boiler is not functioning properly.
First of all you will need to snip the factory connector off near the speaker(s) you intend to replace. Then it is a matter of trial and error to get the correct polarity. If the polarity is reversed, you will still get sound out of the speaker, however, the tone coming out of the speaker will be higher (little to no bass). If that happens, reverse the wires and mount the speakers.
Sounds like you have the wrong switch turned off.
Reverse has nothing to do with it, unless the smoke is coming from your differential. White smoke typically indicates you are burning oil somewhere.
An electric water boiler is a small appliance used to boil water. This can then be used for hot drinks or in a recipe that requires boiling water. An electric boiler is also helpful if the water coming from the tap contains contaminants, because boiling the water will eliminate them.
The reverse lights automatically come on as you put the car into reverse , if they are not coming on your most likely problem is the fuse or bulbs
