How do boilers work central heating

This tank helps deal with the expansion that occurs when the water is heated and also replaces any water that is lost because of evaporation or leaking.

The cold water tank is filled up with water from the mains supply. Once the boiler fires up, it will send hot water to either the hot-water cylinder or the radiators.

As long as the cylinder has sufficient hot water within it, you should be able to access water from multiple taps at once. These conventional boilers can also be fitted with a back-up immersion heater to provide you with access to hot water should you face a boiler breakdown. System boilers provide heating and hot-water using an additional hot-water cylinder. Most of their major heating components are already built in, so they do not require any storage tanks.

They work in a similar manner as heat-only boilers, however they require less additional components. System boilers are sealed pressurised systems. Cold water is sourced directly from the mains supply using a filling mechanism. This water is heated and sent to either the hot-water cylinder where it is stored, or to the radiators. When you need hot water, the system will send it to your taps.

For the most part your central heating system in the home tends to work without much intervention and as a result we often take the whole process and system for granted and presume that it will always provide heat and hot water when we want it.

While our team is interested in the central heating system all the time of course, the only time most people tend to become interested in the central heating system is when it is not working correctly or needs to be fixed.

However, often for many people, understanding how the central heating system works is something that is not always commonly understood. Therefore, a good starting place is to familiarise yourself with the different components that might be in your central heating system and what job those items perform.

It should be noted that not all central heating systems operate in the same way and they can control different things and be made up of different components, so the best place to start is to understand what sort of central heating system that you have in your home.

Identifying this can then help break down what some of the individual components, not only are, but also what they do. The first thing to clarify is that there are several different types of central heating systems available.
