If you are searching for boiler systems, it may seem overwhelming. Most people do not have a lot of experience with the types of boiler, and this lack of practical knowledge can make it difficult to make the right decision. Learning the different types of boilers and differentiating between the three main types of domestic boilers will help you be able to determine which one is best for you. Here are a quick boiler comparison and some questions to ask yourself to answer the question, “What boiler do I need?”
Combination Boiler
A combination boiler, or combi boiler, is typically the most compact type of boiler. It is able to reduce the amount of space it needs to function because it doesn’t need hot water cylinders. Because of the simplicity and smaller size, it is usually faster and less expensive to install as well.
They are also the most efficient type of boiler since the water is heated on demand instead of being stored in a tank. There is also no need to program the hot water to turn on, and you won’t run out of hot water since it is heated on demand. They also take up less room for smaller spaces.
Because the water is heated on demand, it can also take longer to fill a bath since the water flow is reduced. If more than one appliance is running at a time, the combination boiler may struggle to keep up with the demand for hot water.
System Boiler
A system boiler is similar to a conventional boiler, but it has a lot more of the necessary components built into the system. They don’t need a tank in the loft, so they take up less space and are easier to install.
They are a great way for larger homes to have access to hot water from more than one tap at a time without the large bulkiness of a conventional boiler. Sometimes you will have to wait for the hot water to heat up before you can use it, and if you have a lot of people using the hot water at once, you can run out.
Even though they are smaller than a conventional boiler, you will still need space to house a hot water cylinder. There is more plumbing needed for a systems boiler than a combination boiler, so it will take longer to install. You will also see a little more heat loss from the hot water cylinder, so they are not as efficient as the combination boiler.
Conventional Boiler
A conventional boiler is a kind that most people are most familiar with. It has a hot water tank or cylinder that stores the hot water. With this system, gallons of water can be heated and stored to give you easy and quick access to a lot of hot water.
Conventional boilers are perfect for large homes with multiple bathrooms. They don’t have the heat on demand, so you will have to wait for the water to heat up when you want to use it. You can also run out of hot water if there are a lot of people using it and you need room to house a hot water cylinder and a water tank in your home. Installation for this kind of boiler system takes the most time because there are more components that need to be installed.
What Type of Boiler Do I Need?
Knowing the boiler types in the UK is only the start of your research. Now that you understand the three main kinds of boiler systems, you can apply that knowledge to your specific situation and determine which is the best for you.
UK’s Gas Network
Even though a lot of homes have a gas boiler and heating system, they are not present in all homes. If you are not already connected to the UK’s gas network, then it may make more sense to use an oil-powered central heating system. If your home is already connected, then moving forward with a gas central heating boiler makes sense.
Number of People in the Household
The number of people that live in your home is a big factor when it comes to determining which type of boiler is a good fit for your family. If you install a boiler that is too small, you will not have enough hot water to meet your needs, and your home may not be heated adequately. If you choose a boiler that is too big, you will end up using more energy than you need and have to pay more for utility bills.
If you have a large family, then you may want to consider a conventional or system boiler because they can produce larger amounts of hot water. Smaller families will use less hot water, so it makes more sense for them to save some money with the combination boiler.
Number of Bathrooms
While this question is a little bit similar to the last one, it is important to consider the number of bathrooms in your home separately. If you have several bathrooms that tend to be used at the same time, then your hot water demand will be much higher than a home with only one bathroom.
Smaller homes like flats or houses with one bathroom typically only need a combination boiler to meet their needs. A combination boiler will probably not be adequate for a home with more than one bathroom. If you were to use a combination boiler in a larger home, you would see a decrease in available hot water as well as a decline in water pressure.
Free Space Available
You also need to think about the free space available in your home, like a loft or airing cupboard. While the demand for hot water is an important consideration, you can’t overlook the amount of space a boiler system would take up in your home.
If you have a higher demand for hot water and heating, and you also have a loft or room with adequate storage, then a conventional boiler with a large storage tank is a viable option for you. Conventional boilers heat water with cast iron heat exchangers and store it, so if you have the room to house it, you will have gallons of hot water ready whenever you need it.
Homes that have a high demand for hot water and heat, but don’t have a lot of room for storage, then a system boiler is the better choice. They work in a similar way to conventional boilers, but the main difference is that the heating components are built into the actual boiler. It does still need a cylinder for storing the hot water, but it takes up much less room than a conventional boiler.
Homes with very limited storage and low demand for hot water should use a combination boiler. Hot water can be enjoyed on-demand without the use of a water tank or cylinder for storage. It won’t be able to handle multiple appliances being in use at once, but if that is not an issue, then this option is the best for you.
Number of Radiators in the House
The number of radiators in your home will help you know what kilowattage of boiler you will need—the flow rate increases as the kilowattage increases. If you live in a flat, apartment, or a smaller house with ten or fewer radiators, then you will probably only need a 24-27kw combination boiler. You will need 28-34kw if you have 15 radiators in a three or four-bedroom house. A larger house will generally require a 42kw boiler to keep up with heating and hot water demands.
Why May I Want a New Boiler?
Installing a new boiler may be a good choice for many different reasons. New boiler systems are more efficient, which offers a lot of benefits. You may be able to lower your monthly utility bills and reduce your carbon footprint.
Newer boilers are more efficient because they are condensing boilers. Condensing boilers work to make sure that as much heat as possible is usable heat for your home, so nothing is wasted. The Energy Saving Trust says some people may save up to £200 a year when converting from an old boiler to a new boiler.
Combination, system, and conventional boiler systems all have energy-efficient models that can be used to replace older models. If you are especially interested in being eco-friendly, then there are many systems that have an ECO mode to help give you more control over your temperature.
Are You Thinking of Installing a New Boiler?
The time and expense needed for the installation of a boiler system will depend on the kind of system you are using. Larger systems will take more time to install than a smaller system.
