Something To Consider Before Installing a Boiler


Thinking of installing a boiler? While the DIY approach may be appealing, it's often more efficient, faster and safer to have a certified specialist handle the job. However, if you don’t go ahead installing it yourself, here are some key factors to consider:


 Type of Boiler

  • Combi Boiler: Suitable for smaller homes, providing on-demand hot water.
  • System Boiler: Ideal for homes with more than one bathroom.
  • Conventional Boiler: Best for larger homes, but requires a separate water tank.

Boiler Size

  • Choose a boiler size that aligns with the square footage and needs of your home. An improperly sized boiler can lead to inefficiency and increased energy costs.

Energy Efficiency

  • Opt for a high-efficiency boiler to maximize long-term savings on your energy bills.

Budget Considerations

  • Factor in not just the cost of the boiler, but also installation and any additional parts. It's advisable to get multiple quotes for comparison.

Legal Requirements

  • Familiarize yourself with local regulations and secure any necessary permits before proceeding with the installation. A certified installer can often assist with this.

Pre-Installation Assessment

  • Have a qualified technician assess your home to determine the optimal location for the boiler, considering factors like ventilation and utility connections.

Installation Location

  • The boiler should be installed in an accessible location that allows for easy maintenance, commonly in utility rooms, basements, or garages.

Ventilation Requirements

  • Ensure the chosen location has adequate ventilation for safety and optimal boiler operation.

Utility Connections

  • Make sure the necessary utility hookups like gas, water, and electricity are readily available in the chosen location.

Qualified Installation Team

  • Choose a certified and experienced team for the installation to ensure quality work and safety compliance.

Post-Installation Checks

  • After the installation, conduct tests to confirm the boiler is operating correctly. Keep all warranty information and manuals for future reference.

Emergency Contacts

  • Maintain a list of emergency numbers for boiler repair and maintenance services for quick access in case of any issues.

By carefully considering these factors, you can ensure a successful and hassle-free boiler installation. Hiring a certified specialist can streamline the process and offer peace of mind and is always the suggested route to take.



How To Install a Boiler

For the most part, changing or replacing your old boiler with a new one for the same time can be a wise move because it makes the process go a lot easier, but the benefits of changing it to an energy-efficient and strong boiler seems to be more appealing for people. Once you've figured out the type of boiler you need, the proper size, and where you need it to be placed, then you should be good to go and start with the process:

Removing The Old Boiler: Before you start removing or unscrewing anything, you should shut the gas off in your home, then break the gas feed so you can safely cap it. Then you should handle the valves by isolating the boiler from your home's water supply. After that, you can safely remove the gas pipe because it will no longer be needed; the next step would be to unmount the boiler, so you have space for the new one.

Alter The Pipe Work: Most old boilers were designed to get the air back to the boiler and that wasn't very efficient. So, you should alter the pipes in a way where you can add new extra piping in the middle with a filter and ventilator and it would take any excess air out through the installed air vents.



Installing The New Unit: This step is best done on the same day you removed the old boiler and it's outdated pipes; it's best to get new ones, but you could always thoroughly clean and wash the pipes to be ready for the new one. The boiler should be mounted accordingly on the same spot or scale it depending on the size; you should connect the unit to the pipes and pumps and then to the radiators, water supply, and other outlets. Depending on the type of boiler, you might need to connect water storage tanks for the hot and cold water.

The Controls: After you've dealt with the hard work, you should now connect it to the electrical controls unit. This is useful for everyone who wants the ease of access method to change the home's central heating without going to the boiler room directly.

Test It Out: At this point, now you're good to go, so it's time to make sure everything was done correctly. Start the boiler and test the waters to see if everything is working as planned. Check the thermostat levels and every faucet and shower in the house, testing the central heating system too. Go back to the boiler and notice if there is anything out of order, then when you find that everything is secure and ready, you're all set to enjoy this newly installed boiler heating system.

Whether you hire a professional to install it or you do it yourself, you will have a decent heating system that can offer multiple purposes. This boiler can heat the water coming out of your faucets and shower, it can keep your pool warm, you can steam clean your carpets, and it can heat up the air in your home. So, it's an excellent addition to your home and it's worth all the money spent if you find the right one that suits your needs.
