Choosing a New Boiler for Your Burnley Home: Types and Costs

The three boiler types and which suits your home

Most Burnley homes run on mains gas, so the choice usually comes down to three types of gas boiler. The right one depends less on the brand and more on how many bathrooms you have, how much space you can spare and what your water pressure is like.

• Combi: heats water on demand with no tank or cylinder. A good fit for the two and three bedroom terraces common around Burnley, where space is tight and there is one bathroom.
• System: stores hot water in a cylinder, so two showers can run at once. Worth considering for larger semis and detached homes with two or more bathrooms.
• Regular (heat only): works with a cylinder and tanks in the loft. Usually fitted as a like-for-like replacement where the existing pipework would not suit a sealed, pressurised system.

What a new boiler costs in Burnley

Prices vary with the boiler, the house and how much has to change, so treat these as realistic local ranges, not quotes. They cover the boiler, fitting and the usual extras.

What moves the figure is mostly labour and extras: relocating the boiler, upgrading the gas supply pipe to 22mm, a new flue route, a system flush, a magnetic filter and smart controls. A cheaper quote that leaves out the flush or filter is not really cheaper, because sludge from old radiators is one of the main things that shortens a new boiler's life and can affect the warranty.

If you receive certain benefits or have a low household income, check what energy efficiency help is currently open through Burnley Borough Council or your energy supplier before paying in full. Schemes change often.

• Like-for-like combi swap in the same position: roughly £1,800 to £3,000
• Converting from a regular boiler with tanks to a combi: roughly £2,800 to £4,500
• New system boiler with an unvented cylinder: roughly £3,500 to £5,500

Things that matter in Burnley homes

Much of the housing here is stone terrace built before 1919, and that shapes the job. Flues must finish a set distance from windows, doors and neighbouring boundaries, which can be awkward where the boiler sits on a rear wall facing a narrow back yard or back street. Sometimes a vertical flue through the roof, or a different boiler position, is the cleaner answer.

Winters here are cold enough to freeze an external condensate pipe, one of the most common reasons a perfectly healthy boiler locks out in January. Ask for the condensate to run internally to a waste pipe where possible, or in wider, insulated pipe if it has to go outside.

Burnley's water is soft, so limescale is far less of a concern than sludge in older radiators and pipework. Mains pressure and flow vary from street to street and can be lower on higher ground, and a combi can only deliver what the main supplies. A good installer will measure the flow rate at your tap before recommending one.

Sizing and what to ask before you say yes

Bigger is not better. An oversized boiler cycles on and off, wastes gas and wears faster. As a rough guide, a 24 to 30kW combi suits most one bathroom terraces and semis, while 30 to 35kW or more is for bigger homes with higher hot water demand. The number of radiators, the insulation and the flow rate should decide it, not a guess from the doorstep.

Modern condensing boilers run at around 90 per cent efficiency or better. If yours is 15 years old or more it may be nearer 70 to 80 per cent, so the saving on gas can be meaningful, though it depends on how you use your heating.

• Is the installer Gas Safe registered? Ask to see the ID card and check the back covers boilers.
• Does the quote include a system flush, magnetic filter, flue and controls?
• How long is the manufacturer warranty, and does it depend on an annual service? Typical cover runs from 5 to 12 years.
• Will you receive a Building Regulations compliance certificate and a completed Benchmark checklist afterwards?
