Thinking About Replacing Your Boiler in Kildare or Dublin?

If you're planning a boiler replacement or installing a new energy-efficient boiler, you’re probably wondering: “How long does it take to install a new boiler?”

At Freeman Plumbing Services, we make the process fast, efficient, and hassle-free. In most cases, we can complete a boiler installation in just one day, depending on the system type and your home’s requirements.

Average Time to Install a Boiler

For most standard combi boiler installations, the job takes around 6–8 hours. However, more complex setups may take up to 2 days. Here’s a typical breakdown of our installation timeline:

Day 1: Removal and Preparation

• Disconnect and safely remove your old boiler.

• Dispose of the old unit responsibly.

• Inspect and prepare the space for your new boiler.

• Ensure all pipework and connections are ready.

  
  

Day 1–2: New Boiler Installation

• Position and install the new boiler.

• Connect to gas, water, and heating systems.

• Run necessary wiring and controls.

• Perform system checks and full functionality testing.

• Complete safety inspections.

  
  

Final Steps

• Provide a Gas Safety Certificate.

• Demonstrate how to use your new boiler.

• Schedule a follow-up visit for added peace of mind.

  
  

🔧 Our team always ensures your system is installed to RGII standards, giving you a safe, efficient heating system that’s built to last.

What Can Affect Boiler Installation Time?

Several factors can influence how long it takes to install a new boiler in your home:

1. Type of Boiler

• Combi boilers are typically faster to install as they don’t require tanks or cylinders.

• System and regular boilers may require more time for tanks, pipework, and ventilation.

  
  

2. Condition of Existing Pipework

• Old or corroded pipes may need replacing.

• Additional plumbing work can add to the overall time.

  
  

3. Power Flushing

• If your heating system requires a power flush (to clean out debris or sludge), it will add about one extra day.

  
  

4. Location and Accessibility

• Difficult-to-reach installations (e.g., lofts or tight cupboards) may increase the time needed.

• Relocating the boiler can also extend installation duration.

  
  

How to Prepare for a Smooth Boiler Installation

You can help ensure a quick, smooth installation by preparing your home ahead of time:

✅ Choose the Right Boiler Location

Combi boilers can be installed in kitchens, airing cupboards, or even lofts, while other boilers may need special ventilation or space for water tanks.

✅ Insulate Your Pipes

Pipe insulation improves heating efficiency and prevents winter pipe bursts. It’s a smart upgrade before installation.

✅ Clear the Area

Make sure the space around your boiler is clean and accessible so our engineers can get straight to work.

✅ Plan for Ventilation

Ensure there’s proper airflow, especially for sealed system and regular boilers, which require specific ventilation standards.

Additional Considerations for Boiler Installation

When planning your boiler installation, consider these additional factors to ensure everything goes smoothly:

Understanding Your Heating Needs

Every home has unique heating requirements. It’s essential to assess the size of your space and the number of radiators you have. This assessment helps in selecting the right boiler size and type.

Energy Efficiency Ratings

Choosing an energy-efficient boiler can lead to significant cost savings on your energy bills. Look for models with high efficiency ratings to maximise your investment.

Warranty and Support

When selecting a new boiler, consider the warranty provided by the manufacturer. A longer warranty often indicates a higher quality product. Additionally, ensure that you have access to customer support for any future queries.

Local Regulations

Familiarise yourself with local regulations regarding boiler installations. Compliance with these regulations is crucial for safety and efficiency.

Final Thoughts: How Long Will Your Boiler Installation Take?

While most boiler installations in Kildare and Dublin are completed in just one day, every home is unique. Factors like boiler type, system age, and plumbing condition can influence the timeline.
