If you’re considering upgrading your heating system, you might be wondering, “What happens when a new boiler is fitted?” While the process might seem daunting at first, boiler installation is usually straightforward and efficient, with minimal disruption to your home. In this blog post, we’ll walk you through the steps involved in fitting a new boiler, so you’ll know exactly what to expect from start to finish. Whether you’re replacing an old unit or fitting a boiler for the first time, understanding the process will help make the transition smoother.
Step-by-Step Guide to Boiler Installation
When you have a new boiler installed, there are several key stages involved. Here’s a step-by-step guide to what you can expect during the installation process.
1. Initial Survey and Consultation
Before the installation begins, a qualified heating engineer will conduct a survey of your home to determine the best boiler type and location. During this consultation, they’ll assess your current heating system, discuss your needs, and help you choose the right boiler based on your property size and water usage.
If you’re replacing an old boiler, the engineer will also check the existing pipework and connections to ensure they are compatible with the new model. This initial assessment is crucial as it helps avoid complications during the installation.
2. Preparation for Installation
Once you’ve chosen your new boiler, the next step is preparing your home for installation. The engineer may turn off your existing heating system and drain the water from the pipes to prevent leaks or spills during the work. Any old equipment, such as the old boiler or water tank, will be carefully removed at this stage.
If you’re installing a boiler in a new location, the engineer may need to adjust or upgrade the pipework. This might involve some drilling or adjustments to your home’s infrastructure, but heating engineers take care to minimise disruption and mess by using protective sheets and cleaning up after the work is done.
3. Fitting the New Boiler
What happens when a new boiler is fitted will depend on the type of boiler you’ve chosen. For example:
- Combi Boiler: A combi (combination) boiler is a compact unit that heats water directly from the mains, so there’s no need for a separate hot water cylinder or storage tank. This makes it quicker to install and requires less space in your home.
- System Boiler: A system boiler is slightly larger as it requires a hot water cylinder, which is often installed in an airing cupboard or utility room. The boiler itself is fitted to the wall, and the engineer will connect it to the existing pipework and cylinder.
- Conventional Boiler: Conventional boilers are more complex to install as they require both a hot water cylinder and a cold water storage tank. However, if your home already has a conventional setup, the installation process is generally straightforward.
During the fitting, the boiler will be securely mounted to the wall, and all necessary connections—gas, water, and electrical—will be made. The flue, which allows waste gases to escape, will also be installed or upgraded if needed.
4. Testing and Safety Checks
Once the new boiler is in place, the engineer will carry out a series of safety checks to ensure everything is working correctly. This includes testing the gas connections, ensuring the flue is safely installed, and checking the water pressure.
The heating system will be turned on, and the engineer will test the boiler to ensure it’s operating efficiently. They’ll also check the radiators and hot water supply to confirm everything is working as expected. If any issues are detected during testing, the engineer will address them before completing the installation.
5. Commissioning the Boiler
Once all the tests and safety checks are completed, the engineer will commission the new boiler. This means setting the boiler to its optimal settings for efficiency and performance, ensuring it meets the manufacturer’s guidelines.
The engineer will also explain how to operate your new boiler, including how to adjust the temperature, set timers, and use the controls. If your boiler comes with a smart thermostat, they’ll guide you through the setup process so you can start controlling your heating remotely.
6. Documentation and Warranty
After the installation is complete, you’ll receive all the necessary documentation for your new boiler. This includes a Building Regulations Compliance certificate, which confirms the boiler has been installed in line with UK safety standards, and the manufacturer’s warranty, which will protect your boiler for a set period.
The installer will also provide a service logbook, which records the details of the installation and any future servicing or maintenance carried out on the boiler. It’s important to keep this document in a safe place, as it may be needed to validate your warranty.
How Long Does Boiler Installation Take?
The time it takes to fit a new boiler depends on several factors, including the type of boiler, the complexity of the installation, and whether any additional work is required (such as upgrading pipework). A straightforward combi boiler replacement can often be completed within a day, while a more complex system or conventional boiler installation may take two to three days.
