Every year, one out of every five boilers fails. Early troubleshooting, a yearly boiler service, and simple preventative steps could prevent many of these boiler problems. To begin the troubleshooting process, it’s recommended to take help from a licensed expert if you’re having issues with boiler controls or central heating issues. Working on a boiler without proper maintenance is a risky activity that could put your life and someone other’s life a risk

The article will walk you through 5 of the most frequent condensing boiler issues.

1: The Boiler Keeps Turning Off

One of the most common boiler problems is when a boiler gets warm and then turns off (nearly weekly). The central heating goes on, then off, in a cycle that repeats every several minutes or seconds.

To avoid this problem, you need to make sure that the gas boiler installation has been done in the best manner possible. Double-check once the installation has taken place and ask the experts to wait until you run a few test rounds to see whether it is performing or not.

How to Fix: 

The most likely reasons for the boiler getting turn off frequently are mentioned below: 

  • The pressure in the boiler is going down.
  • The thermostat isn’t working.
  • The pump is either leaked or ruined.
  • Valves are closed, combating the entry of water.

It’s time to call the experts for replacement. 

2: Boiler Is Losing Pressure

One of the biggest issues one can ever face is a loss of pressure. 

A frequently asked topic is whether a boiler may lose pressure without leaking. No, is the response. A leak, no matter how little, always causes actual pressure loss. It’s possible that you won’t be able to observe the leak.

You may have a tiny leak if you see low boiler pressure when the heat is turned on. The extra heat puts too much strain on the fractured part in this situation, causing it to spill which should not be in any case. 

You have a larger leak on your hands if your boiler loses pressure when the boiler is turned off.

3: Boilers Making Sound 

As boiler parts deteriorate, the associated boiler difficulties may result in noises. Central heating pumps are one of the most typical sources of these noises. They can accumulate air over time, causing an airlock.

Fortunately, you can solve this problem. To remove an airlock from a central heating pump, place the pump below the boiler casing. To allow air to escape, a small bleed screw is incorporated.

4: No Hot Water, but Central Heating Works (or Could be Opposite)

One of the most prevalent boiler problems with outdated systems is the diverter valve, which is usually the culprit.

The diverter valve switches between hot water & central heating settings in your boiler. When you turn on a shower, the valve prioritizes hot water above central heat. When you turn off these fixtures, the central heating system receives heat.

Due to dirt and sludge build-up, the valve may become stuck over time. It will stay in hot water mode if this happens.

5: Radiators are Cold 

It’s critical to determine which portion of your radiator isn’t operating if your radiators aren’t heating up properly. We frequently encounter new radiators that have not been regulated properly. The proper amount of hot water enters each radiator when radiators are balanced, resulting in a uniform distribution of heat.

Problems with heating and boilers come in many forms and sizes. Make sure to get timely repairs or replacement before the boiler entirely gets damaged
