What is a System Boiler?

A system boiler heats the central heating system in your home and provides hot water, which it stores in a tank or cylinder. System boilers differ from conventional boilers because they draw the water from the mains, which they then heat up and store in the cylinder. A conventional boiler uses cold water stored in a tank, usually in the loft, for its supply.

The difference between a combi boiler and a system boiler is that the system boiler heats the water in advance, allowing you to access hot water immediately as long as there is some remaining in the cylinder. With a combi boiler, the mains water runs into the boiler, which comes to life when the hot tap is turned on. This means that you have a wait a short amount of time before the temperature of the water begins to rise.

As system boilers use water from the mains, they are great for running high pressure showers as long as the supply into your home is adequate. This is not always possible with a conventional boiler. Another advantage of choosing a system boiler over a conventional boiler is that they take up less room. They only require a hot water cylinder and a boiler unit, meaning you don’t need to find room for a cold water tank as well. This is particularly helpful if you live in a small property, you do not have a loft or you do have a loft, but you are considering converting it into a living space.

How Does a Boiler Feed System Work?

The water comes into the system boiler from the mains supply and is heated using a heat exchanger. From there, these boilers supply hot water to the radiators in your central heating system and fill up a tank or cylinder ready to supply your taps and showers when needed.

The majority of the components needed for the system boiler to work are situated within the main boiler unit. This includes the pump, which efficiently distributes the hot water around the house, making a system boiler an effective way of keeping your home warm and with instant hot water on demand.

The boiler uses a condensing system to recycle the energy from the flue gases that would otherwise go to waste, preheating the cold water. This makes system boilers more efficient by helping them reduce the CO2 your home consumes, especially if you keep your hot water tank well insulated.

System boilers are ideal for homes with multiple bathrooms and where numerous sources wish to use hot water at once. As the water is preheated, all requests can be dealt with at once, maintaining the temperature and pressure in the way that a combi boiler cannot. Once the cylinder is empty, it needs to refill and reheat in order to provide the home with more hot water.

What is the Cost of a New System Boiler?

Just as there are a wide range of different makes and models of system boiler, there are also big variations in price. The cost of a new system boiler depends on the quality of the model and the size of the boiler too. If you have a large home and require a more powerful boiler with a bigger hot water cylinder, you will pay more than for a smaller boiler with a smaller hot water tank in a basic range.

You can buy system boilers costing between £600 and £2,500 for the unit alone, which is why we will undertake a survey on your home to match you with a boiler that is good quality, powerful enough to meet the needs of your family and within your proposed budget.

What Size System Boiler do I Need?

When we talk about the size of the system boiler you need, it is in relation to how powerful it is in kilowatts, rather than the physical size of the unit itself. System boilers need to be able to cope with the number of radiators in your home to provide effective central heating and the size of the hot water cylinder you have to ensure there is always hot water. If you are buying a new cylinder or hot water tank at the same time, you need to carefully consider the amount of hot water your family uses. Once the cylinder is drained, you then have to wait for it to fill and heat up again before you can use the shower, run the bath, do the washing up and so on.

The hot water flow rate is less important with a system boiler than it is with a combi boiler, as it stores the water in a tank, rather than heating it on demand.

If you own a home with up to ten radiators, you can generally look at system boilers of between 9 and 15kW. If you have up to 15, you might need a boiler with an output of between 18 and 25kW, and bigger properties usually need larger sized system boilers. However these figures are merely to be used as a guide, and our experienced staff will be able to advise you accurately on the ideal boiler for you when they come to survey your home.
