Understanding The Boiler Installation Process In Clapham
A boiler replacement doesn’t have to be stressful when you know what’s coming. Here’s a complete breakdown of what happens during the boiler installation process in Clapham.
What Are The First Installation Steps?
It all begins with a site survey. One of our qualified Clapham heating engineers will visit your property to assess your existing heating system, discuss your needs, and evaluate technical requirements.
This stage helps determine:
- The most suitable boiler type and size
- Whether you need a system upgrade
- Pipework layout and installation feasibility
- Ventilation and flue position
- Water pressure (measured in bars, not psi)
We’ll also recommend the best options for your property, whether you’re exploring ideal boiler installation in Clapham or other models that meet your efficiency and budget goals.
What Happens During Boiler Install Day?
The installation steps are straightforward but require expertise and attention to detail:
- Isolate gas and water supplies to remove the old unit safely
- Drain the system cleanly to avoid water damage
- Remove the existing boiler and prepare the wall for your new unit
Fit the new boiler and all necessary fittings, including:
- Pipes
- Valves
- Filters to protect from iron oxide buildup
- Pressure reducing valve for safe operation
- Install a modern thermostat (if part of your package)
- Make all Gas Safe checks and complete thorough testing
Our team ensures the installation complies with all UK building and gas regulations.
How Long Is The Installation Timeline?
The timeline for a standard boiler replacement in Clapham is typically 1–2 days. A more complex system upgrade, relocation, or older pipework may extend the process slightly.
We always keep homeowners informed and aim to minimise disruption during the work.
Post-Installation Checks And Commissioning
After fitting the boiler, we carry out a full commissioning process. This includes:
- Testing all controls and thermostats
- Bleeding radiators and topping up the system
- Checking water pressure (between 1–1.5 bars is typical)
- Registering your boiler for the manufacturer’s warranty
- Providing you with a Gas Safe certificate
We’ll also walk you through how to operate your boiler and where to check levels, pressure, and settings. If you ever run into minor issues, our step-by-step boiler reset guide can help you get things running again.
