boiler overheating

Overheating of boilers is extremely hazardous. It is troublesome when the boiler suddenly started to get overheated. This leads to safety issues as there have been multiple cases where boilers often explode due to overheating.

Boiler rods also get damage by overheating and sometimes pass electric current in water because of damaged rods of the boiler due to overheating, which is quite dangerous. There can be multiple reasons for it but the most common ones include limescale build-up, failed thermostat, system blockage, etc.

Now we understand how dangerous the impact of overheating in is a boiler can be, it becomes extremely essential to recognize if the boiler is overheating or not.

Signs When Boiler is Overheating?

In many cases, the main cause of an overheating boiler is a total shutdown. The latest boilers will stop working immediately when they have become unsafe to use. This often occurs when the boiler gets overheated, and boiling pressure within the boiler has ascended to a vicious level. To stop water boiling pressure from getting extremely dangerous so that boiler can explode, that’s why boiler gets shut down to stop the overheating process.

If the boiler stops working and overheating is suspected, make sure you turn off the boiler or water as well for safety measures. This will cut power to the boiler and stop water running into the unit if other measures of safety fail, and it will stop the risk of pressure ascending in the boiler. If you fail to turn off power and water, it results in a rapid ascend in boiling pressure which helps the steam to continuously increase in the boiler, which then leads to a dangerous explosion.

Although there are indicators in the boiler which shows the boiler is getting overheated. However, the new boiler has a mechanism that turns the boiler off in case of overheating and hence escaping from the risk of explosion.

If you encounter your boiler often turning off automatically, then there are high chances that the boiler is facing overheating issues.

Things to do when the boiler is overheating?

Why do boilers overheat?

We at Rapid Response Plumbing And Heating have been involved with the boiler repair and boiler installation in London for a very long time thus we wanted to share some of the reasons which we found for the boiler overheating.

Limescale build-up– Limescale often builds up due to the hard water. These then choke the heat exchangers running across the house leading to overheating issues of the boiler.

Faulty Thermistor– Thermistors are used for measuring temperature. These are responsible for regulating the temperature of the water. Due to long runs, these often get damaged and give a faulty reading and lead to heat the entire system. In most such cases it is advised to replace the thermistor. If ever you get to know about similar stuff immediately contact the engineers. They can let you know if the thermistor needs to be changed or it can be repaired. Also, they are trained to fix it efficiently and help you in the long run.

System Blockage– These are more likely to take place in old boilers. Due to rusting the metal scrape gets collected at some part of the boiler. This is the most common issue we encounter. If the boiler starts making a lot of noise or some of the radiators don’t get heated up chances of system blockage are very high. The best way to escape system blockage is by flushing the boiler thoroughly.

Damaged Pump– The pump which manages the water supply often becomes the reason for overheating of the boiler. Due to improper supply of water heating increases and leading to the issues.
