Boilers: 3 things to consider before buying

Before purchasing boilers, it's crucial to assess your home's heating requirements. Consider factors such as the size of your home, the number of bathrooms, and how many people live there. For larger homes with multiple bathrooms, a system boiler might be more efficient as it can supply hot water to several taps simultaneously. Conversely, for smaller homes or flats, a combi boiler could be more suitable due to its compact size and ability to provide instant hot water. By understanding your specific needs, you can choose boilers that offer the best efficiency and comfort for your household.

Energy efficiency is a key consideration when buying boilers. Look for models with high energy efficiency ratings, as these will not only reduce your carbon footprint but also save you money on energy bills over time. Most modern boilers come with an ErP (Energy-related Products) rating; aim for one that's A-rated for maximum efficiency. Additionally, consider whether the boiler has features like modulating burners or weather compensation controls, which can further optimize energy use based on real-time conditions.

When budgeting for boilers, factor in installation and ongoing maintenance costs along with the purchase price. Installation costs can vary depending on the complexity of the setup and any additional work required, such as upgrading pipework or installing new radiators. It's advisable to get quotes from several qualified engineers to ensure competitive pricing. Regular maintenance is also essential to keep boilers running efficiently and safely; consider setting up a service plan with a trusted professional to cover annual inspections and any necessary repairs.

BOILERS

FAQ

Boilers are heating systems that provide hot water or steam for various applications. They work by heating water using fuels like gas, oil, or electricity. Boilers are essential for central heating and can also supply hot water for domestic use. Consider energy efficiency and size when choosing one.

Choosing the right boiler depends on your home's size, heating needs, and fuel availability. Boilers are available in different types such as combi, system, and conventional. Assess your space and hot water demand to determine the best fit.

Combi boilers are units that provide both heating and instant hot water without a separate tank. System boilers require a cylinder for storing hot water but can handle higher demands. Combi boilers save space, while system boilers suit larger homes with multiple bathrooms.

Several brands are known for their quality and reliability. Each offers unique features that cater to different requirements.

  • VAILLANT: Known for their energy efficiency and innovative technology.
  • Baxi: Offers a range of compact and powerful models.
  • Worcester Bosch: A popular choice for their durability and performance.

Types of boilers

Understanding the different types of boilers can help you make the right decision for your home heating needs.

Combi boilers

Electric boilers

Electric boilers are ideal for homes without a gas supply. They are quiet, efficient, and have a simple installation process. These boilers are environmentally friendly, as they do not emit carbon emissions. Electric boilers are suitable for smaller properties with lower hot water demands.

Key features to consider

When selecting a boiler, consider the following features to ensure it meets your needs.

Energy efficiency

Look for boilers with high energy efficiency ratings. This not only reduces your carbon footprint but also lowers your energy bills. A-rated models are the most efficient, ensuring optimal performance.

Size and capacity

Choose a boiler that fits your space and meets your hot water needs. Combi boilers are compact, making them suitable for smaller homes. Larger properties may require a system boiler with a separate hot water tank.

Smart controls

Modern boilers often come with smart controls. These allow you to manage your heating remotely via a smartphone app. Smart controls can help you save energy by adjusting the heating schedule based on your lifestyle.

Boiler spare parts

Having access to boiler spare parts is crucial for maintenance and repairs. Brands like VAILLANT, Baxi, and Worcester Bosch offer a wide range of spare parts to ensure your boiler remains in top condition.

Making the right choice
