If your boiler isn’t producing heat or if its performance is very poor, there are several possible causes of the problem. We’ve put together this guide to help you pinpoint the exact issue that is keeping your boiler from operating the way it is supposed to.
The first thing to check is whether the power source feeding the boiler is in working order. If the boiler’s source of power is cut off, the boiler won’t function. The fi
xes for this are quick and easy, so they should be the first solutions that you try when faced with a boiler issue.
There could be a number of things that lead to the boiler losing power. Usually it is because the circuit breaker has been tripped or blown out. You can fix this by simply resetting the circuit breaker.
If resetting the circuit breaker doesn’t work, check if a fuse has been blown. If it has, and this impacts the boiler’s power source, simply replacing the blown fuse should solve your problem.
Another simple thing that may cause the boiler to malfunction is that it’s on the wrong setting. Ensure that the boiler is on “heat mode” and that the temperature setting is correct. Try turning the temperature setting up or down by a few degrees to see if its heat production is impacted.
If you’ve tried to address the power problems with each of these quick fixes, but your boiler still doesn’t work or its performance is still weak, you may have a more complicated problem on your hands.
If there’s a sudden change in the heating performance of your gas-powered boiler, or if it stops altogether, the most likely source of the problem is that the boiler’s water level is too low.
Checking the reading on the combination pressure gauge will give you an idea of the boiler’s water level. The automatic filling system for the boiler should maintain the pressure at a level between 12 and 15 psi. But if the water pressure reading is below 12 psi, water must be added to the system in order to bring the boiler back up to peak performance.
If the problem arises gradually rather than suddenly, there may be deposits in the system that must be flushed out. If you don’t know how to perform this task, it is best to call a service technician to carry it out.
If you find that none of the above solutions help out the problem, there may be an issue with the boiler’s expansion tank or with the circulator pump which may lead to water leakage. These are more complex problems, and will likely require the help of a boiler technician.
Although in-home remedies can repair certain problems with gas-powered boilers, it is always a good idea to check with a service technician if the issues aren’t quickly resolved. A service technician can pinpoint the exact cause of your problem, and get your boiler back up and running in no time.
