Common Boiler Problems

Common Boiler Problems

For those with gas fired hot water boilers, you can get reliable heat at an affordable price. However, just like all heating systems, problems can arise over time. Here’s a list of common boiler problems, so you can take matters into your own hands.

The Boiler Produces No Heat
Causes: When the boiler itself does not produce heat, first check that there is power going to the fixture and that it also has a sufficient water level. Afterwards, check to see if the pilot light and the thermostat are malfunctioning.
Solutions: If there is no power going to the boiler, reset the circuit or replace any blown fuses. Keep the water level at about half full for maximum efficiency. For a broken pilot light or thermostat, replace them or go about the steps to troubleshoot these parts.

All of the Radiators Aren’t Heating
Causes: When some of the radiators are failing to heat up, trapped air is usually the culprit. There can be trapped air in the lines or in one of the radiators. When the radiator has a trapped air problem the top half will be at a cooler temperature than the bottom half.
Solutions: Each radiator will have a bleed valve at the top of the radiator. Open this valve until all of the air is out and water begins to squirt out. The circulator should also be checked because this is what helps sends the water throughout the entire heating system.

The Pipes Are Too Noisy
Causes: Pipes in a heating system like this can start to become overly noisy when the circulator begins to malfunction. There can also be water trapped in the return lines which will cause an abundance of noise.
Solutions: Inspect the circulator to see if any piece of it needs to be replaced. The spring that connects the pump and motor is a common piece that will cause noise if broken. If the circulator is not the problem then check to see if the return lines have a favorable pitch towards the boiler. When the return lines have an uphill slope to the boiler, water can become trapped, thus creating noisy pipes.

Many of these gas boiler problems can be solved with some investigating and home maintenance.
