Most households in the UK use gas boilers for their central heating system. This is utilised to keep the house warm. Some systems, which are called the combination or combi-systems do not just make the temperature of the rooms warmer, but they also supply hot water to the shower and taps.

What is a boiler?

A boiler is one of the parts of the central heating system and can be considered as the most vital one. It can be compared to a huge fire that is continuously supplied with gas for it to keep on burning. This is what essentially heats the water, which in turn makes the temperature of the rooms higher, up to what is set on your thermostat.

Gas central heating systems are typically controlled manually. This means that you have to switch on the system if you wish to make the home warm, and switch it back off if it feels too hot. Having a thermostat installed makes the process more convenient. Set the desired temperature and the thermostat will turn the system on if the temperature falls below what’s set. It automatically turns the system off when the temperature goes above what’s set. Not only is this convenient but it also saves on energy, which means money saved.

Basic Central Heating Process

To give you a better idea of how a central heating system generally works, let’s take a look at the basic process. When your system is turned on, gas coming from the gas network enters the boiler through the pipe. The valve that acts as a door for allowing the gas in to the boiler opens so the gas can enter. The gas is burned by the boiler creating heat.

This heat energy warms the water, which is then pushed by a pump to the radiators, distributing heat to the rooms. The thermostat will monitor the temperature, and as mentioned, turn on or off the system, depending on the temperature set.

If you have a combi-boiler, you’ll have a couple of heat exchangers in the system. One is for heating the rooms and the other is for heating the water. When a tap is used, the system heats the water, and it usually stops from heating the room as it may not be capable of heating both at the same time.

Anything that works with gas needs to be installed properly. If you are planning to have a gas boiler in your home, it’s important that you let only a gas engineer London offers do the job. This will ensure that the work is done correctly, giving you peace of mind for your home’s safety.
