There are three main kinds of heating systems available in today’s market. These are heat-only, combi, and system, each of which has its advantages depending on the usage. Let’s break each one down:
Heat-only:
Heat-only boilers are the oldest heating model still available today; they may also be called “conventional” boilers. These systems only provide heating directly to the radiators in your property. Hot water is supplied separately from a cylinder typically located in an airing cupboard using what is referred to as an open-vented heating system. If your home or property has older radiators, you will likely have a heat-only system. Modern boilers can produce too much pressure to feed through these older appliances and cause problems.
There is also a branch of heat-only boiler called a back boiler placed within the chimney breast behind a fireplace. If this is your current method of heating, then you will be unable to have it replaced when it no longer works. Instead, you will have to choose an alternative combi boiler model.
Combi:
Combination boilers operate from a single unit by doing what their name suggests, combining all the functions of a heating system into one. This removes the need for any hot water tanks in the home, so they take up less of your space. The heating and hot water are provided through an integral heat exchanger supplied by the cold water mains, which is the answer for an immediate hot water supply. This particular type of boiler will is popular in smaller, new-build homes, as it saves space and works out to be cost-effective in the long run.
System:
If you are a large household or residential property, then a system boiler is the best option for you. They include all of the innovative functions of a combination boiler with an extra steel hot water cylinder feature. All critical components are still inside the boiler. Still, they work in a similar style to a traditional heat-only system. They can work effectively with higher demand on the hot water supply, so this boiler is ideal for a household with multiple bathrooms. System boilers can provide a strong hot water flow to various outlets simultaneously, so great for when there is a demand for more than one shower in the morning!
Key Benefits:
Heat-Only
Beneficial in older properties with old radiators, and the boiler component is cheaper to replace.
Combi
More cost-effective to run and low maintenance costs because all the parts are covered under your boiler’s warranty.
System
Excellent option for properties with multiple bathrooms and covered under warranty.
Disadvantages:
Heat-Only
If you require a replacement to your system, only the boiler component is covered under the manufacturer’s warranty. This makes repair or replacement of other parts will come at an extra cost.
Combi
Reduces water flow rate when more than one outlet is using hot water simultaneously. They are also less effective on pipes 15mm or smaller due to their size.
System
Only maintain good water flow so long as your mains water pressure is high enough. They take up additional space with their water cylinder.
So, which heating system is right for you?
The existing features of your property will be able to determine that, and we can narrow it down into the key factors. If your home has an old radiator system, then you are better off opting for a heat-only system so as not to override them. If you are a household with multiple bathrooms or are looking to extend your property, then a system boiler will better suit you. It will give you better, heated water pressure. Gas prices are rising by the day, so if you are concerned about cost or are on a budget, then it is best to stick with what you’ve already got.
If you require a replacement boiler go for a newer version of the current model. For overall low-maintenance and upkeep costs, your ideal option is a combi boiler. This is because it provides all the features you need from a sound heating system, with minimal fees.
Whichever boiler you need in your home, it is crucial to ensure that it is installed and maintained by a licensed professional to be considered gas safe. Getting your boiler checked regularly prevents the risk of potential danger. It also helps your boiler to work as efficiently as possible. British Gas stated that the average household spends fifty-five percent of their annual energy bill on gas. Modern boilers can save you up to £200 a year to heat your property.
