Why is my boiler losing pressure

The pressure loss observed in boilers is a major problem. It can affect the heating and needs to be addressed to avoid huge financial losses. There can be multiple reasons which are listed below:

Check the age of the boiler

Firstly, check the age of the boiler. An old one will involve a huge fixing cost if, e.g., there’s a system leak. At this point, it might be better to buy a new boiler. The repair cost of the old one will outweigh the cost of a new one.

Boiler leak

There might be a leak in the boiler, and such system leaks can happen either due to age or corrosion. Hence, the interior of the hole when inspected by an local plumber and heating engineer helps in detection of the leaks.

Faulty boiler part

The boiler can be broken due to a faulty part or even a broken component. After the part causing the problem is identified, it can either be replaced or removed to avoid further loss in pressure. The pressure gauge is an indicator of whether the boiler is working fine; hence, always keep a close look on it.

The air in the heating system

Do check for the presence of air in the system and before doing so, the radiators need to be thoroughly checked to ensure their smooth functioning. Unnecessary air buildup can interfere with the pressure gauge.

Ensure that the central heating system is working effectively, and there’s no leakage whatsoever. Signs of leakage can be a damp floor, stained roof, corroded pipes and even erroneous radiators.

Pressure relief valve

The pressure relief valves are an essential part of the entire system, and usually, particular debris can get lodged in or grime can get accumulated. The repair or replacement is reasonably affordable.

The expansion vessel

The expansion vessel can also be a cause of the drop in the pressure since, if the expanding isn’t occurring, then it results in ejecting out the water through the pressure relief valve. Thus, the heating doesn’t work as planned.

It becomes easier to handle the issue once the source is known. Hence, identify the source and fix it immediately.
