    Updated: April 23, 2024

    “Many inquiries come to us regarding the timeline for boiler installations. While we can’t give exact estimates due to several factors, we can provide a rough timeframe. The installation duration can vary depending on additional tasks like integrating a smart thermostat, performing a chemical flush, or setting up a system filter. These elements might extend the overall installation process.”

    How Long Does it Take to Fit a New Boiler?

    The timeframe for fitting a new boiler varies depending on several factors, including the type of boiler, the complexity of the installation, and any additional necessary work. Typically, a straightforward replacement can take anywhere from one day to a few days. Here are the main factors that influence the timeline:

    Boiler Type: Different types of boilers, such as combi, system, or conventional, can affect the installation time. Generally, combi boilers tend to install faster than others.

    Location: The location of the installation site in relation to existing pipework and the gas supply can impact the time needed. If there’s a need for relocating or extensive adjustments to the pipework, it can prolong the installation process.

    Additional Work: Tasks like upgrading pipework, installing radiators, or making modifications to the system can extend the duration of the installation.

    System Flush: If a central heating system flush is required, it will add time to the installation process.

    Accessibility: The ease of access to the installation site also plays a role. Difficult-to-reach areas will require more time and effort.

    Regulatory Compliance: Ensuring compliance with safety standards and regulations adds to the overall installation time, as installers must take the necessary steps to meet these requirements.

      How long does it take to replace a combi boiler? 

      Replacing your old combi boiler with a new one is generally a simple task. If your existing combi boiler is causing frequent problems because of its age, it may be time for a replacement. Usually, swapping a combi boiler for a new one takes approximately 4 to 6 hours to complete.

      How long does it take to replace a system/ standard boiler with a combi boiler? 

      “Replacing a system or conventional boiler with a combi boiler typically requires about 2 days. This type of conversion involves additional complexities. Transitioning to a combi boiler entails removing the water tank associated with a system boiler or both the hot water storage tank and water feed tank for a conventional boiler, usually situated in the attic. Rerouting pipework is also necessary. These tasks add complexity, time, and may cause some disruption to your home during installation. However, we aim to minimize disruption by efficiently removing additional pipework and tanks from your premises.

      Is it better to repair or replace a boiler? 

      “Frequently, repairing your boiler is the most economical and effective approach to restore your heating system. If you have a newer boiler that usually functions reliably, replacement is unlikely to be required. Nonetheless, if your boiler is getting older and the expense of repairs becomes unmanageable, replacing it might be the more viable option to contemplate.

      What are the advantages of switching to a combi boiler? 

      “Choosing a combi boiler comes with numerous benefits, particularly the extra space gained by eliminating water tanks. Furthermore, combi boilers are more efficient, which can potentially result in savings on heating costs.

      Another advantage of a combi boiler is the immediate availability of hot water. Unlike conventional boilers that may take time to heat water once the supply is depleted, combi boilers heat water instantly as required, ensuring an uninterrupted supply.

      How long does it take to replace a back boiler with a combi boiler? 

      Replacing a back boiler with a combi boiler typically requires 2-3 days, as back boilers are often the most challenging to replace. Due to their outdated and inefficient nature, replacing them is frequently necessary, especially considering the lack of available parts. With a lifespan of approximately 25 years, if your back boiler is nearing this age, it’s likely time to upgrade to a more efficient model that can help reduce energy bills.

      The removal process can be complex and costly due to the back boiler’s difficult location behind the gas fire. Sometimes, instead of complete removal, they are decommissioned to minimize disruption, given their delicate placement. However, investing in a replacement is worthwhile, providing you with a newer, more efficient boiler that can lead to long-term savings on heating costs.

      How long does it take to move my boiler to another location? 

      “If you choose to relocate your boiler to a different area, the installation duration can be extended, typically adding half a day to the process. However, the timeframe primarily depends on the size of your home. The greater the distance between the current and new locations, the longer the installation may take. Additionally, there may be additional labor costs associated with the relocation, including the moving and rerouting of pipes.

      How long does it take to install a smart thermostat? 

      “Smart thermostats allow for remote heating control via smartphone, providing energy and cost savings by efficiently regulating home heating. Installing a smart thermostat is typically straightforward and can usually be completed in about 1 hour.

      What are the steps of replacing a boiler? 

      • Removing the old boiler 
      • doing a power flush  
      • Upgrades or changes to pipework 
      • Fitting the new boiler 
      • Commissioning of the system 
      • Handover to the customer 
      • And finally registration 

       How long does it take to upgrade the gas supply pipe? 

      “According to Gas Safe regulations, your gas supply pipe must be 22mm thick. Older systems may have 15mm pipes. When installing a new boiler, upgrading your gas pipe is a legal obligation. This process typically requires approximately half a day.”

      How inefficient is a 20 year old boiler? 

      Non-condensing heat-only boilers which are older than 20 years might usually have 60% efficiency, with 40% of their energy being lost. This can happen because some heat is wasted in the form of hot gases released from the flue. 

      How long does power flushing or chemical flushing take? 

      “The purpose of power flushing is to remove sludge and buildup that can accumulate in your heating system over time. During this process, a machine is connected to your system to dislodge the sludge and other debris using high-pressure water flow and a system cleaning agent. Typically, power flushing takes between 2 to 4 hours.

      This procedure is generally recommended for older systems rather than new ones. Power flushing a new system may not be necessary and could be considered unnecessary expense, as older systems are more prone to sludge buildup in the pipes.”
