Questions people ask
What does a central heating system installation include?
It typically includes a new condensing boiler, all necessary pipework, radiators for each room, a thermostat, and a hot water cylinder if you choose a system boiler. The installer will also remove your old heating appliances.
How long does the installation take?
Most installations from scratch take between 3 to 5 days, depending on your home's size and the complexity of the job. Your installer will give you a clear timeline.
Will I save money with a new system?
Yes, absolutely. Modern condensing boilers are much more efficient than older systems, which means lower energy bills and a warmer home. The long term savings can be significant.
Do I need a new hot water tank?
If you choose a combi boiler, you won't need a hot water tank as it heats water on demand. If you opt for a system boiler, a new, insulated tank will usually be part of the installation.
What kind of boiler should I choose?
The best boiler depends on your home size, hot water needs, and existing pipework. Your installer will help you decide between a combi, system, or regular boiler, explaining the benefits of each.
Are there any grants available?
Government initiatives and local authority schemes sometimes offer support for energy efficient home improvements. It's worth checking what might be available in your area when you plan your upgrade.
