An enclosed vessel that is designed to heat and circulate water to produce hot water, steam or superheated steam that is then used to heat, power or generate electricity is known as a boiler. Problems with boilers can be both expensive and dangerous in nature. Many times, these problems arise during the winter when boilers are being operated regularly. That is why it’s important to run periodic checks on boilers throughout the year so that you encounter minimal hassles when operating it.
Listed below are a few questions answered by Experts on the issues related to boilers.
In many cases, the burners or the rocker arm that positions the flame to heat the water sticks which accumulates calcium deposits that can cause this problem. To fix it, turn off the gas and clean the unit using water and vinegar. Also switch off the inlet water and get a hose and connect it to the inlet and outlet. Then fill the water and vinegar solution in a bucket and run it through the unit for one hour. Do this every year to avoid facing the same problem.
You reset the system by turning the power on and off so it should be okay. In case the problem recurs, call a plumber to take a look at it. There might be a problem with the flame sensor.

When the inlet filter gets clogged, it can cause a problem of this nature. Clean and flush the system and then replace the filter to fix the problem.
To begin with, get a deposit remover that is made for potable water systems. Do not use acid as it may poison you. Then get a circulation pump that will take chemicals from the storage tank, pump it through the system and then back into the storage tank. Finally, disconnect the supply of cold water to the boiler and separate the home heating side of it so that chemicals do not flow into that system. You would need to hook up the return line of the pump to every faucet separately and make sure that the chemicals are circulated through every line. Once you are done, each line will have to be flushed with clean water and every outlet will have to be tested to check if there are any chemicals present. Make sure the filter is cleaned before you do this.
There are several steps that you can take to ensure that your boiler is running satisfactorily throughout the year. For example, when the boiler is in use, check it carefully to ensure that there are no leaks, cracks or strange noises. During its peak time of use, such as winter, monitor the pressure gauge and water level every day. If you see a major change in any of these areas, consult a professional immediately. Another important area to check is the boiler's safety valves. Perform a monthly check based on instructions given by the manufacturer. If the valves get corroded, it can cause malfunctioning and pose a safety risk. Finally, get a certified inspector to complete an annual inspection of the boiler. If there are any problems with it, this should come to light immediately before it causes any serious damage. For more information when dealing with boiler problems contact an Expert.
Steam radiators not heating up completely: The radiators won't heat up all the way. Some will heat up a third some only half, and the one in the attached picture only the valve will be hot - none of the radiator gets hot. What should I do. I have let out some water from the boiler and refilled it with clean water. I have set it for several hours straight to check if its just a matter of time, but its not working. Also, is it a problem if one room is too hot to turn off the valve in that room. That way the radiator doesn't heat up. I have checked the pitch
