Feature image

Most of the homeowners do not pay attention to boiler maintenance in the summer months, as they think that the right time is winter when it is needed. But it is important to keep your boiler maintained throughout the year so that its efficiency is not reduced and it works well for a longer duration. Just like any other appliance, boilers also need regular maintenance so there are no unexpected breakdowns. 

It is beneficial to maintain your boiler during warmer months. It helps to identify any minor issues that can later lead to major problems in the winter season. Regular maintenance helps to improve the efficiency of boilers, which in turn results in lower energy bills, and the carbon footprint is also reduced. Moreover, regular maintenance extends the lifespan of the boiler, which in turn saves money as you do not need a full replacement after some time. 

Why Boiler Maintenance Is Important in Warmer Months

Most property owners believe that hot water boilers require maintenance only during winter and not in summer, when hot water is not needed. However, this practice is not valid. If the boilers are not properly maintained during the summer, the system may be damaged, which can lead to problems in the future.

If the system is properly maintained and fixed at time preventing any kind of damage, then one can avoid problematic situations like having to live without hot water during winters. Problems such as leaks, erosion etc may develop in the hot water supply system of the house if proper care is not taken.

As in today’s era, when electricity costs are high, taking proper care of the boilers in the house not only prevents breakdowns and leaks but also helps to improve overall system efficiency, reducing the bills and energy consumption.

Moreover, routine maintenance prolongs the overall lifespan of your boiler. By keeping all components clean, functioning properly, and in good condition, you can delay the need for a costly replacement and enjoy reliable heating for years to come. If the system is properly maintained, cleaned, and eroded parts are replaced when required then the overall life efficiency of the boiler is increased and one can avoid problems such as the need to buy a new boiler and high expenses for fixing the system.

In short, maintaining and fixing the boilers during the summer is a smart idea as it is less costly and more effective.

Key Boiler Maintenance Tasks to Perform in Warmer Months

Boiler Maintenance

For your life to remain hassle-free, maintenance and inspection of the boiler should be done before the time comes. Some of the tasks that are to be performed off-season are listed below:

  • Regular Visual Inspection

Firstly, start checking the boiler and its parts. Thoroughly look out for leaks, damage dust to erosion, dirt, dust, pipe damage, and other problems. Turn the system on and listen to the sounds. If it seems strange, then it indicates that air might be trapped inside, or some parts may not be working properly.

In months when boilers are not in use, the system pressure drops as can be detected by a pressure gauge. During the summer, the pressure normally remains 1-1.5 bar. Modern boilers have a Pilot light that indicates the boiler's normal workings. If the pilot light is not working, it indicates that the system needs inspection.

  • Bleeding Radiators

If the radiator is not working efficiently, it may be due to air trapped in the system. As a result, the heating efficiency of the system is lowered. The air trapped has to be removed for efficient air flow. Safely bleed your radiators by following these instructions:

  1. Shut down the system and let the boiler cool down.
  2. At the top edge of the radiator valve is a present.
  3. Use a tool as advised to open the valve. As it is open air, trapped inside is released.
  4. Then close the valve once water starts to move steadily.
  5. After all this, the pressure of the boiler is to be checked.
  • Check Boiler Pressure

The pressure of the boiler can change, especially when the system is not in use. Off-season pressure normally ranges between 1-1.5 bar. If the pressure drops, then one should follow the following tips:

  1. Find a flexible silver loop under the boiler.
  2. Gradually open the valves in the loop. Check the pressure level.
  3. After reaching the recommended pressure, close the valves.
  4. Then turn on the boiler and check if the pressure remains constant.

Always read the instructions manual of the boiler, as every model is different and is operated differently.

  • Clean Boiler Components

Cleaning and wiping of the system is necessary to keep the system in good condition, as dust and dirt can block the air flow through pipes and flues and reduce the overall efficiency of the system.

  • Clean or replace filters, as the dust trapped can lead to blockages.
  • Thoroughly cleaning the parts of the boiler to get rid of dust.
  • Cleaning of the pipes and flues for proper air flow.

Cleaning and wiping of the boiler components increase energy efficiency and overall life span of the system.

  • Test the Thermostat and Controls

In the off-season, checking whether the system is in good condition is much easier.

  • Checking if the thermostat and boiler operate properly when settings are changed.
  • Scheduling the system’s work (if it is advanced) during summer helps prevent unnecessary gas usage.
  • If the room’s temperature does not remain consistent, it means that the thermostat is not working properly and that the system needs to be checked.

Optimal energy consumption and efficiency of the system are guaranteed if the system is fully functional.

  • Schedule Professional Servicing

Hiring professionals for a thorough inspection of the system is important to keep the boiler system in good condition. The professionals will make sure that:

  • Each part of the system is checked and tested.
  • Burners and heat exchangers are cleaned properly.
  • Maintenance of the safety tools and alarms.
  • Thoroughly inspect the system for leaks and damages.
  • Making sure that the system remains in an overall good condition.

Inspection of the boiler by hiring professionals helps to prevent problems even before they fully develop and reduces the risks of costly repairs. They make sure that the system remains in good condition. Inspection and maintenance of the system off-season helps to increase the life span of the system and one can enjoy a hassle-free life.

Signs Your Boiler Needs Attention During the Warmer Months

Off-season maintenance of the boiler is also a very important task to avoid problems in the future. Early maintenance results in cost-effective repair and is safe for the environment. If water is seen dripping from the boiler, it is a serious sign that the system needs repair. Additionally, if the system makes unusual sounds, like whistling or banging, it shows that it requires maintenance.

If the radiators remain cold when boilers are turned on or the heating is inconsistent, it is a sign that the system is not efficient and needs fixation. Also, if flashing lights or unusual codes appear on the display, gas safety engineers should be hired for inspection. Leaks and defects in the boilers can be spotted by regularly checking the pressure. If it is below the range recommended by Gas safety engineers, then it is a sign that the system needs repair.

Gas safety engineers should be hired for proper maintenance and inspection of the boilers off-season, as it helps to avoid heating problems during winters and in case of wear and tear, early fixation can help to reduce the cost for repairing the system.

Benefits of Off-Season Boiler Maintenance

Inspection of the boiler system before winter is much more approachable and advantageous. Servicing of the boilers in summers helps to keep it in good condition. Also, it helps to prevent any heating problems in winters. Hiring Gas safety engineers in the summers is easy as the cost leads and slots are easily available. The professionals are not easily available during winters as they have to deal with gas safety problems. It is not so good for your wallet so booking slots before time is the right choice.

This is good for both your wallet and the environment. In summer, when boilers are not used more often, maintenance and inspection of the system help to save energy consumption, thus reducing overall household expenses. Regular inspection and system checking are a more efficient way to keep your system in good condition. Maintenance of the boiler system twice a year helps to increase the system's life span and keeps life hassle-free.

To conclude, inspection and fixation of the boiler system when not in use is a more sensible and time-saving way to keep yourself free from problems.

Boiler Maintenance Safety Tips

Maintenance of the boilers is a critical task. The tenants can perform some regular checks, but they should always be careful and attentive while doing so.
