4 Common Oil Boiler Problems and What to Do About Them

1. 4 Common Oil Boiler Problems and What to Do About Them Many thermal fluid heater problems occur after long periods of hot oil boiler systems being idle—for instance, turning off heating during warm seasons. No boiler system is immune to issues caused by regular use and natural wear and tear. It’s important to know the common problems that you are likely to experience so you’ll know what to do about them when they occur. Liquid Process Systems Inc. will be by your side in case of more serious breakdowns or when experiencing unaddressed minor issues that could lead to more serious problems. Below are some of the most common issues you will likely experience with your hot oil boiler system and what you can do about them: ● Low pressure​ – ​hot oil boiler​ pressure that is too low can be detrimental to your central heating system. This can cause your thermal fluid heater to malfunction. Low boiler pressure can result from various causes such as a leak in your system, a leaking coil, or a pressure relief valve that needs replacing. One of the easiest ways to detect the cause of low pressure in your hot oil boiler is to find any visible leaks in the system. In case of a leak, it is best to call a professional to seal the system and restore the correct operating pressure. If no leaks are found, re-pressurizing the boiler might be enough to bring your pressure gauge back to the correct levels. ● Non-heating radiators ​– Cold radiator patches are also a common problem with hot oil boiler systems. This is often due to sludge build-up, water or air that gets trapped inside the system, resulting in unequal heat distribution. Boiling out the water is a simple fix for this common problem and venting will release trapped air. ● Strange boiler noises ​– If your ​thermal fluid heater​ is making strange noises, it is most often caused by water or air in the system, a faulty pump, or low pressure. A more serious problem to watch out for is kittling, which results from limescale buildup within the system though that is seen with steam boilers. ● Intermittent heat​ – It is also common for boilers to produce intermittent heat, which can be caused by low fluid flow velocity, broken pump and valve parts, faulty thermostat, low fluid levels, or faulty motorized valves. Replacement of these components might be needed to fix the problem. Liquid Process Systems supplies a wide array of heat transfer fluid filtration and thermal fluid filtration products for use in thermal fluid heating systems and hot oil boilers.
