The longer a company has been in business, the more experienced it is. They’ll also know how to deal with potential problems and offer tips for maintenance. Make sure the company has an extensive support system that will allow you to ask any questions and get a response quickly. If they don’t, move on to another company.

Checking the fireside of a boiler

Inspect the fireside of a residential boiler at least twice a year. It is the place where the flue gas passes through the boiler. The fireside is accessible behind inspection covers. To reduce fouling, you should clean the surface with a mild detergent. You can also apply a thin layer of mineral oil to minimize the amount of dirt and debris on the fireside. Aside from the fireside, the boiler’s refractories, tube sheets, furnace, and water connections should all be examined.

Checking for a leak

If you notice a pool of water around the pressure outlet pipe on your boiler, it’s likely a sign of a leak. You should have a professional check the joint if you suspect a leak. The pressure inside your boiler is regulated by a pressure gauge that should be green or red. If the needle has dropped to the red side, you may need to have a professional bleed the boiler. 

Several components of your boiler can be corroded over time, including the heat exchanger. The heat exchanger is the most vulnerable part of your boiler, and replacing it is the most effective solution. In addition, if you notice water coming out of the fittings, you can have the heat exchanger replaced.

A leak is a sign of an underlying problem and requires a new boiler installation. It can cause several things, including:

  • A worn seal
  • A leak around the pipe
  • Corrosion

A trained engineer can identify any issues and fix the problem to prevent further damage. In this case, you should contact a professional as soon as possible to get it repaired.

Cleaning the fireside of a boiler

A fireside maintenance visit will include cleaning the boiler’s tubes and the refractories. It will also involve checking for carbon, soot, and slag deposits, as these decrease the boiler efficiency. The cleaning should be completed over two to three hours and may involve the use of a power flush. Using a high-pressure hose will help remove any loose scale or residual sludge.

Once the pressure gauge shows a lower pressure, turn the radiator valve a half-turn at a time until it reaches the correct pressure. If the system has a water leak, the leak could cause a significant amount of damage to the flooring. A rag should be nearby to catch the dripping water. Begin bleeding the radiator valve on the farthest away from the boiler, such as a downstairs radiator. Afterward, turn the valve counterclockwise until no more air comes out.
