Discussing the Basics of Central Heating System in Easy Words
There’s a heating system installed in every home but not everyone knows the kind of system that they are using. Having some information about your heating system always proves helpful, says an experienced gas safe engineer in London. Especially at times of crisis, it helps you to better explain the problems that you’re facing with your system to the plumber or heating engineer.
A broad overview of how central heating systems work
The central heating system operates by circulating in even and constant motions, says a qualified mechanic who deals with central heating installations in London. As a result of this constant circular motion, hot water is pushed to the heating elements to accumulate more heat. To make things easier, let us break down the operation in simple steps:
- Fuel to run the boiler comes from a storage unit or an external source.
- Boiler burns the fuel to create flaming jets, resulting in the heating up of the copper pipe that contains water.
- The heat created by the jets on the copper pipe is then transferred from the pipes to the water within.
- An electric pump then pushes the hot water through the system touching the upper floor levels.
- Water keeps flowing around the enclosed circuit while delivering hot water to each radiator. A pipe-work connects the radiators to the system.
- Water enters the radiator from one side and leaves from the other. The water is also a little cooler as it leaves the radiator.
- After the water has passed through all the radiators, it has turned much cooler and re-enters into the boiler to get heated again.
- A thermostat monitors the activity of any boiler. It automatically switches on the boiler when the temperature drops below the set value.
- Similarly, once the temperature goes too high, the thermostat instructs the boiler to deactivate any operations and switch off.
Different types of boilers
Different types of boilers are available in the market.
- Combi boilers: This variety of boilers is widely seen across the UK homes. One of the main reasons behind their popularity is that this range of boilers can heat up the surroundings almost instantly without much turnaround time.
- System boilers: These are the same as Sealed System Boilers. Unlike that in a conventional boiler, system boilers do not need large storage tanks to keep heated water. So, you don’t have to allocate a large space to operate these boilers. Instead of a water storage tank, they use a cylinder to contain water.
- Conventional boilers: These are also called Regular Boilers or Open Vent Systems. They come with both a water storage tank and a cylinder. Usually, residential properties do not install this range of boilers. But a group of expert central heating engineers in London suggests that if your home requires hot water at several locations at the same time, then this is the best option.
When there is a demand for hot water at several places at the same time, it is likely that the water pressure will reduce. As a result, a person standing under the shower often gets burnt because of the fluctuation of the hot water.
