| Biomass Boiler | £7,000 – £15,000 | £10,000 – £18,000 | £15,000 |
Combi Boiler Cost Breakdown
Combi boilers are a popular choice due to their efficiency and compact design. They provide both heating and hot water on demand, eliminating the need for a hot water cylinder. The cost for a new combi boiler can vary:
- Price Range: £1,500 to £4,500 (including installation)
- Factors Influencing Cost: Boiler size, warranty length, installation complexity, and local labour costs.
Combi Boiler Pros:
- Space-saving design.
- Instant hot water on demand.
- Highly efficient, making it a cost-effective choice for many homes.
Combi Boiler Cons:
- It may not be suitable for large homes with high demand for hot water.
System Boiler Cost Breakdown
System boilers are ideal for homes with higher hot water needs, such as those with multiple bathrooms. Unlike combi boilers, they require a hot water cylinder, which may increase installation costs.
- Price Range: £1,700 to £5,000 (including installation)
System Boiler Pros:
- Ideal for larger homes with higher hot water demands.
- Can supply hot water to multiple taps simultaneously.
System Boiler Cons:
- Requires space for a hot water cylinder.
- Slightly more expensive to install than a combi boiler.
Conventional Boiler Costs
Conventional boilers, also known as regular or heat-only boilers, are one of the more traditional systems. These boilers are best suited for homes with older heating systems that may not withstand the pressure of modern boilers.
- Price Range: £1,700 to £4,500 (including installation)
Conventional Boiler Pros:
- Suitable for homes with multiple bathrooms.
- Ideal for areas with low water pressure.
Conventional Boiler Cons:
- Requires both a hot water cylinder and a cold-water storage tank.
- Requires more space.
Electric Boiler Costs
Electric boilers use electricity rather than gas, making them a good option for homes without access to the gas grid.
- Price Range: £1,700 to £4,500 (including installation)
Electric Boiler Pros:
- Environmentally friendly as they don’t burn fossil fuels.
- Suitable for smaller homes or flats.
Electric Boiler Cons:
- Higher running costs compared to gas boilers.
Oil Boiler Costs
Oil boilers are often used in rural areas where gas is not available. They operate similarly to gas boilers but use oil stored in a tank.
- Price Range: £2,500 to £5,500 (including installation)
Oil Boiler Pros:
- Suitable for homes without gas supply.
- Reliable and efficient.
Oil Boiler Cons:
- Requires a storage tank for the oil.
- Higher installation and running costs.
Boiler Conversion Costs
Switching from one type of boiler to another, such as from a conventional to a combi boiler, can significantly impact the overall cost. These conversions involve more labour, pipework, and sometimes additional components.
- Price for Conversion: £1,500 to £4,500 (depending on the complexity)
Factors That Affect Boiler Replacement Costs
Several factors can influence the total cost of replacing a boiler:
- Boiler Type: Combi, system, or conventional boilers all have different price ranges.
- Installation Complexity: Moving the boiler to a new location or upgrading pipework can increase costs.
- Labour Costs: These vary by location, with areas like London generally more expensive.
- Additional Components: Features such as smart controls, magnetic filters, or upgraded heating controls can add to the total cost.
- Brand and Model: Premium brands come at higher prices but often include longer warranties and better build quality.
How Much Can a New Boiler Save You?
