Central Heating Systems

When installing a new central heating system such as a radiator direct into your home, it is important to be aware of the various types of central heating systems available to you. Usually, your central heating system will work easily without any form of intervention meaning your heating appliances, from towel rail radiators to convector radiators, to any other type of radiator, will work seamlessly. Read on to find out about the different types of free gas central heating systems available, so you can make an informed decision on your purchase.

Combi Boilers

Combi (combination) boilers are a modern type of heating system. These are responsible for both the heating of water, and the heating of your home. This comes as one single unit, making them great if space as at a premium. Hot water within these systems instantly heats up, making them great in terms of energy expenditure, as well as having the ability to save you time. With a multitude of advantages, combi boilers are popular in modern buildings, especially houses and flats of a smaller size. As one of the most modern types of central heating systems, this option is often most desirable in contemporary homes. Find the best iheat boilers here!

System Boilers

System boilers differ to combi boilers primarily in the fact that they require and additional hot water tank. As they store water within this, a constant supply of hot water is available. Often these are found in larger buildings, usually those with multiple bathrooms, where an excess amount of hot water is required.

Conventional Boilers

Conventional boilers, also known as regular boilers, are older types of central heating systems. These require a hot water tank, similarly to system boilers, but the key difference is that they additionally require a cold-water tank in the loft (a header tank). Issues with conventional boilers include the fact that they take up space and require a loft to situation the extra tank within. A conventional boiler such as this is often used to replace another regular boiler. Often chosen for environments where water pressure is low, this type of central heating system does require some additional kit in order to compensate for the lack of a water tank. Also known as a closed system, these are pressurised central heating systems, which is worth taking into consideration.

Condensing and non-condensing boilers

Condensing and non-condensing are terms that simply refer to the way in which the boiler itself functions.  Condensing boilers are far more efficient, using less fuel ultimately. A non-condensing boiler possesses a singular heat exchanger chamber. This is where hot gases from the burner pass through in order to heat up the water. This occurs within the walls of the exchanger, ultimately reaching the exit flue

Whether it is a condensing or non-condensing boiler, all central heating system works by fuel being brought into the boiler and converted into heating energy, due to water boiling in your system. This can be done through a variety of ways, with fuel such as gas or oil being common ways of the creation of thermal energy. Additionally, some boilers run through electricity.
