Boiler Replacement Cost Considerations

Getting an accurate quote for your boiler replacement isn’t going to be a straightforward process because there are many factors that can affect the actual cost. It’s a good idea to find information on the key concerns, as they may bring to light aspects of the process that have been overlooked. For example, the suggestions below:

Boiler siting: Thinking about where the boiler unit should be fitted is vital, and potentially more complex than you’d imagine. You will probably need an exterior wall for the flue, and need to find a spot that is easy to access, yet out of the way. Consider the pipework needed to connect your boiler to radiators, and also whether to have your boiler wall mounted, or standing.

Re-using your existing system: If you get the opinion of a professional fitter, it could be that some, or much of your current pipework and radiators could be fit for re-use in the new system. A quick cleaning procedure and you can save money on costly pipes, and even a water tank.

Volume: If you are running a B&B your boiler will need to have a much greater capacity than if you live in a two bedroom flat. Consider the quantities of hot water and energy for central heating your boiler needs to deliver. And don’t forget to factor in the hidden costs of pipework, if you are refitting a large house.

Do you need a combi boiler? Look carefully at the differences between a combi boiler and a regular boiler using a water tank. There are advantages and disadvantages depending on your needs and priorities – a combi boiler produces unlimited hot water on demand, but there is always a delay when you first turn on the tap.


Make sure you do your research thoroughly, get a few different quotes and with the right boiler system you could be saving money on the cost of your fuel for years to come.
