Types of Boilers Available Under the Free Boiler Scheme in 2025

The Free Boiler Scheme in 2025 is an initiative aimed at helping households replace outdated, inefficient boilers with modern, energy-efficient models. This reduces energy bills and contributes to a greener environment. Understanding the types of boilers available under this scheme can help homeowners make informed decisions. Reliant Energy Services is one of the providers offering this service, ensuring eligible households receive cost-effective heating solutions.

1. Combi Boilers

Combi (combination) boilers are one of the most popular choices in the UK due to their efficiency and space-saving design. These boilers provide both heating and hot water without requiring a separate water tank. They are ideal for smaller homes with limited space.

Advantages:

  • High energy efficiency
  • Compact and space-saving
  • Instant hot water supply

2. System Boilers

System boilers are suitable for homes with higher hot water demand. They require a separate hot water cylinder but do not need a cold water tank, making them a good choice for larger households.

Advantages:

  • Consistent hot water supply
  • More efficient than traditional boilers
  • Suitable for multiple bathrooms

3. Regular (Conventional) Boilers

Regular boilers, also known as conventional boilers, are ideal for homes with existing radiator systems and older heating setups. They require both a hot water cylinder and a cold water storage tank.

Advantages:

  • Compatible with older central heating systems
  • Can provide hot water to multiple taps at once
  • Ideal for larger properties

4. Biomass Boilers

Biomass boilers use organic materials such as wood pellets or logs as fuel. They are an eco-friendly alternative to gas and oil boilers, helping to reduce carbon emissions.

Advantages:

  • Environmentally friendly
  • Can reduce heating costs in the long term
  • Eligible for additional renewable energy incentives

5. Condensing Boilers

Condensing boilers are designed to be highly efficient by recovering heat from exhaust gases that would otherwise be lost. These boilers are now standard in most modern installations.

Advantages:

  • Higher efficiency compared to non-condensing models
  • Lower energy bills
  • Reduced carbon footprint
