  • Considerations such as the cost of installation and features should be taken into account when selecting a system boiler.
  • Comparing different types of boilers can help homeowners make an informed decision to find the most cost-effective heating solution for their home.

New System Boiler Prices

According to our experts, new system boiler prices range from £1,600 to £3,500, depending on factors such as:

  • Brand
  • Size
  • Output
  • Fuel type

But how do these factors impact the overall cost, and what should you consider when estimating the price for your home? We will investigate these aspects further.

System boilers are popular in the UK for their ability to provide central heating and hot water to homes with multiple bathrooms or high hot water demand.

In addition to the boiler cost, there might be additional expenses for installation and setup, which can vary depending on the complexity of the installation and the need for additional components, such as hot water cylinders or thermostatic radiator valves.

Brand impact on system boiler cost

You have likely seen multiple different boiler manufacturers throughout your time as a homeowner. Knowing which system boiler brand best suits your home and what price range they are in will help you massively in deciding on your new boiler.

The brand of the system boiler can affect the price, with premium brands typically costing more but offering better quality and longer warranties. For instance, Worcester Bosch, a renowned brand in the UK, can have a higher price tag when compared to other market offerings.

However, other brands like Baxi can be priced more competitively. Consider the advantages and disadvantages of each brand, including aspects like:

  • Reliability
  • Efficiency
  • Performance
  • Warranty
  • Aftercare and servicing

Different system boiler brands offer warranties ranging from 1 to 10 years, which can have an impact on the overall cost. Longer warranties can provide greater peace of mind, and some brands may even offer extended warranties that can be purchased for an additional fee.

When comparing system boiler prices, always consider the warranty offered by different brands.

Size and output considerations

The size and output of the system boiler will impact the cost, with larger boilers for bigger homes generally costing more. Choosing the correct size to meet your home’s needs is important, considering aspects like the size of the property, the number of occupants, and the demand for hot water and heating.

Moreover, the efficiency of the boiler should be taken into account, as this will impact the running costs and potential savings on energy bills.

Choosing the right size and output for your system boiler is key to achieving efficient heating and cost-effectiveness.

Generally, the larger the boiler, the higher its output in kilowatts (kW), meaning a larger system boiler can deliver more heat and hot water, making it suitable for larger properties or homes with a higher demand for heating and hot water.

Fuel type and efficiency

Throughout the UK, boilers use different types of fuel to power them, with the fuel depending on the type of boiler you have installed. For example, a boiler could use natural gas as the fuel, or you may have an oil system boiler or an electric boiler.

The fuel type and efficiency of the system boiler will also affect the price. Here are some factors to consider:

  • Gas boilers: These are popular in the UK due to their cost-effectiveness and ease of connection to the gas grid. However, they have higher carbon emissions than other fuel types.
  • Oil boilers: These are more affordable upfront but may be less efficient and eco-friendly compared to other options.
  • Electric boilers: These are generally more expensive upfront but are highly efficient and eco-friendly.
  • LPG boilers: These are an alternative to gas boilers and are often used in areas without access to the gas grid.

LPG system boilers are more eco-friendly than gas or oil boilers but require an external tank and can be more expensive to run. On the other hand, electric system boilers are the most environmentally friendly option, with efficiency ratings of up to 99% but higher running costs due to electricity prices.

When selecting the best system boiler for your home and budget, keep in mind the fuel type and energy efficiency.

Types of System Boilers and Cost of System Boilers

Having examined the factors influencing new system boiler prices, we will now discuss the various types of system boilers, including:

  • Gas system boilers
  • LPG system boilers
  • Electric system boilers
  • Oil system boilers

Each system boiler type has unique advantages and disadvantages. Understanding these differences can aid in making a knowledgeable decision when selecting the right system boiler for your home.

From the most popular gas system boilers to the eco-friendly electric options, the choice of fuel type and boiler features can significantly impact the overall cost and efficiency of your heating system. We will now examine how each type of system boiler works and their respective costs.

Gas system boilers

Gas system boilers are popular in the UK due to their affordability and easy connection to the gas grid, but they have higher carbon emissions than other fuel types.

These boilers provide central heating and hot water to homes with multiple bathrooms or high hot water demand, making them a common choice for many households.

The typical cost of gas system boilers in the UK ranges from £600 to £900 for an economical model and from £900 to £1,300 for a mid-range system boiler.

However, prices can fluctuate based on the brand and specific boiler features, so comparing prices and features is important to determine the most suitable option for your needs.

LPG system boilers

LPG system boilers utilise liquid petroleum gas (LPG) as their fuel source and are more eco-friendly than gas or oil boilers. However, they require an external tank and may be more costly to run. LPG boilers are a suitable option for homes that do not have access to the gas grid, offering a more environmentally friendly alternative.

The typical costs of LPG system boilers range from £2,300 to £4,300. These boilers are known for their high efficiency, with over 90% of the fuel being converted into usable energy, making them comparable in efficiency to other types of boilers.

Considering the installation and running costs of LPG system boilers is important when comparing them to other fuel options.

Electric system boilers

Electric system boilers are the most environmentally friendly option but can be more expensive to run due to higher electricity costs. These boilers operate by heating water directly from the mains when a hot tap is turned on, eliminating the need for a hot water storage cylinder or a cold water storage tank.

The typical cost of electric system boilers ranges from £1,500 to £2,500 for the boiler unit, with installation costs ranging from £500 to £1,500.

Although electric boilers typically have higher efficiency ratings, up to 99%, the higher running costs due to electricity prices can make them less cost-effective in the long run compared to gas or oil boilers.

Oil system boilers

Oil system boilers are suitable for homes without access to the gas grid, but they require an external oil storage tank and can be more expensive to install and run. These boilers are popular in rural areas where gas connections are not available, and they offer a dependable fuel option.

The price range for oil system boilers is approximately £1,560 to £2,550, excluding installation costs. Although oil boilers can be just as efficient as gas and LPG boilers, their installation and running costs can be higher due to the need for an external oil storage tank and the fluctuating price of oil.

Comparing System Boiler Costs with Other Boiler Types

Having an understanding of system boilers and their costs, it’s important to contrast them with other boiler types, such as combi and conventional boilers, to assist you in making the best decision for your home’s heating needs.

By comparing the costs and features of each boiler type, you can ensure that you’re getting the most suitable and cost-effective heating solution for your home.

Each boiler type has its own set of advantages and disadvantages, and understanding these differences can help you make an informed decision when choosing the right boiler for your home. We will now examine combi and conventional boilers more closely to see how they compare to system boilers in terms of cost and functionality.

Combi boilers

Combi boilers are more compact and provide instant hot water, making them a popular choice for smaller homes and those with limited space. These boilers have the following advantages:

  • They heat water directly from the mains when a hot tap is turned on, eliminating the need for a hot water storage cylinder or a cold water storage tank.
  • They are energy efficient, as they only heat the water that is needed.
  • They provide a constant supply of hot water, without the need for waiting for a storage tank to heat up.
  • They are easy to install and require less pipework.

The typical range of combi boiler costs is between £1,500 and £2,500.

While combi boilers can be more cost-effective and space-saving, they may not be suitable for larger homes with high hot water demand.

In such cases, a system boiler or a conventional boiler might be a better fit, as they can provide a more consistent supply of hot water for multiple bathrooms and higher heating demands.

Conventional boilers

Conventional boilers, also known as regular or traditional boilers, require additional components and space, including a hot water cylinder and a cold water tank, but can be more suitable for homes with multiple bathrooms or low water pressure.

A regular boiler operates by heating water in the hot water cylinder, which then supplies the household’s central heating system.

The typical cost of a conventional boiler ranges from £1,500 to £3,000, making them comparable in price to system boilers. When considering a conventional boiler, it’s important to weigh the benefits and drawbacks, such as the need for additional space and components, against the potential advantages of providing a consistent hot water supply for homes with higher heating demands.

System Boiler Installation Costs

System boiler installation costs can vary depending on factors such as the complexity of the installation, the need for additional components, and the installer’s fees. The estimated cost range for system boiler installation is £650-£2,500.

To secure the best rates for system boiler installation in your area, it’s recommended to consult several installers and use services which can link you with up to 3 local, vetted installers for a system boiler installation.

A licensed heating engineer should be consulted for a system boiler installation. They can conduct an in-depth evaluation of your home and suggest a boiler that is precisely sized and suitable to satisfy your specific needs.

By obtaining several quotes and comparing the services provided by various installers, you can make sure you’re getting the most excellent boiler installed at a competitive price.
