Common signs include strange noises (banging, whistling, or gurgling), leaks or dripping, loss of pressure, no heat or hot water, the pilot light going out frequently, a yellow or orange flame instead of blue, and error codes on the display panel. If you notice any of these signs, it’s advisable to contact a professional for an assessment.

It’s recommended to have your boiler serviced annually by a qualified technician. Regular servicing can ensure that it operates safely and efficiently, extend its lifespan, and can help prevent unexpected breakdowns, especially during colder months when the boiler is most needed.

Important factors include the type of boiler (combi, system, or conventional), the size of the boiler (which should match the size of your property and heating needs), energy efficiency ratings, the brand’s reputation for reliability, and the availability of spare parts. It’s also important to consider the location for the boiler and any potential modifications needed for installation.

Boiler installation is a complex process that involves gas lines, plumbing, and often electrical work. It’s not recommended as a DIY project due to safety concerns and the potential for costly mistakes. Always hire a certified professional to install your boiler to ensure it’s done safely and complies with local building codes and regulations.
