When it comes to upgrading your boiler, it’s essential to understand the various types available and the fuel options that best suit your needs.  At Warmable, we are here to guide you through the process and help you make an informed decision for your next boiler upgrade.

Find below further information on the types of boiler you might come across as you look to upgrade your current boiler.

Combi Boilers: Efficiency and Space-Saving Convenience

Combi boilers, short for combination boilers, are a popular choice among homeowners. These boilers provide both hot water for your taps and central heating from a single unit, eliminating the need for a separate hot water cylinder or cold water storage tank.

One of the significant advantages of combi boilers is their high energy efficiency. Since they heat water on demand, they avoid the energy losses associated with storing hot water in a cylinder.

Combi boilers are also compact and space-saving, making them ideal for smaller properties where space is at a premium. Their fast heating capabilities ensure quick hot water delivery, enhancing convenience in your daily life.

System Boilers: Excellent Water Pressure and Multiple Hot Water Outlets

System boilers, also known as sealed system boilers, work alongside a separate hot water cylinder but do not require a cold water storage tank. These boilers are suitable for larger homes that demand a high volume of hot water.

One of the primary advantages of system boilers is their ability to provide excellent water pressure throughout your home. This means you can enjoy powerful showers and efficient water flow to multiple hot water outlets simultaneously.

System boilers also eliminate the need for a loft tank, making them a space-saving option for homes with limited loft space. With their efficient heating capabilities and excellent hot water performance, system boilers offer a balanced solution for households with higher hot water demands.

Conventional Boilers: Traditional Heating with Separate Hot Water Storage

Conventional boilers, also referred to as regular or heat-only boilers, are the traditional option found in many older properties. These boilers work in conjunction with a separate hot water cylinder and a cold water storage tank, often located in the loft.

While conventional boilers may be considered less energy-efficient compared to combi and system boilers, they remain a reliable choice for homes with existing heating systems that require replacement.

Conventional boilers provide a constant supply of hot water to multiple outlets simultaneously, making them suitable for larger households. Their compatibility with renewable heating technologies, such as solar thermal systems, allows you to further enhance energy efficiency and reduce your carbon footprint.


Fuel Options: Choosing the Right Energy Source for Your Boiler

In addition to understanding the different types of boilers, it’s important to consider the fuel options available. Here are the main types:

  • Gas Boilers: Gas-fired boilers are the most common choice in the UK due to the widespread availability of natural gas. Gas boilers provide efficient heating and hot water, offering reliable performance and cost-effectiveness. They are also considered environmentally friendly, with lower carbon emissions compared to other fuel types.
  • Electric Boilers: Electric boilers are an alternative for properties that don’t have access to a gas supply. They are compact and can be installed in various locations within your home. Electric boilers are known for their silent operation, low maintenance requirements, and precise temperature control. However, they may have higher running costs compared to gas boilers.
  • Solar Boilers: Solar thermal systems use the sun’s energy to heat water, providing a renewable and environmentally friendly option. Solar boilers can be integrated with your existing heating system, supplementing the energy supply and reducing reliance on conventional fuel sources. They are most effective in sunny climates and can significantly lower your energy bills while reducing your carbon footprint.
  • Oil Boilers: Oil-fired boilers are a viable choice for properties not connected to the gas grid. They are efficient and provide a high level of heat output. While oil boilers require a storage tank for the fuel, modern models are designed to be more energy-efficient and environmentally friendly, reducing emissions and improving overall performance.
