Our homes are comfortable havens thanks in part to our quality central heating systems. However, for all the good it does to your day-to-day life, it’s likely you still don’t really understand how your home stays warm and cosy.
With this in mind, the team at Gastech have decided to create a handy guide to demystify the process and explain just how your central heating system ensures your home is a comfortable space.
The central heating system
When it comes to understanding your central heating system, it’s best to remember that it works in constant circle, pushing hot water from your boiler and around your home. You may be surprised that the same water is locked within your system and goes around the circuit over and over, unless it is flushed.
Whilst the system is a circuit, there are various steps that contribute to your central heating:
● Gas enters your system from an external source.
● Your boiler then burns the gas, making hot jets that heat a copper pipe known as a heat exchanger. The exchanger is filled with water which heats up.
● A pump then pushes the hot water throughout your heating system.
● The water travels around the closed circuit, entering radiators around your home. The hot water enters one side and leaves out the other, significantly colder than when it entered.
● A thermostat monitors the temperature and switches off the boiler once it gets hot enough.
● Waste gases that are produced are dispersed into the air from a smokestack called a flue.
Types of boiler
Although a heating system relies on the above steps to run properly there are also different types of boiler to choose from, with each model offering different advantages and disadvantages.
Combi boiler - As the most popular boiler type, combi units control both hot water and central heating, making them the smallest option on the market. Heating the water directly from the mains, combi boiler owners have unlimited hot water, however, they can struggle in properties with low water pressure.
System boiler - For homes with more than one bathroom, a system boiler can be a great choice. Only requiring a hot water storage cylinder, the lack of a water tank frees homeowners from the worry of any leaks or frost damage and offers superior pressure for homes in need.
Conventional boiler - Comprised of both a cylinder and water tank, the conventional boiler, also known as the traditional, regular or open vent boiler, are by far the largest models on the market. As they require a large amount of space, they are not well-suited to smaller properties, however, they are great for homes with excessively low water pressure.
