How Much Does Boiler Installation Cost?
Boiler installation costs can vary depending on several key factors, including the type of boiler you choose, the complexity of your home’s heating system, and whether you’re replacing an old unit or installing a new one from scratch.
On average, the cost to install a boiler ranges from $3,500 to $7,500 for standard systems, with high-efficiency boilers and combi-boiler installations running closer to the $8,000–$12,000 range due to advanced technology and energy savings over time.

Common Boiler Issues Every Homeowner Should Know:
Understanding the most common boiler problems—like low pressure, no heat, and unusual noises—can help homeowners take proactive steps to avoid costly repairs and ensure their heating system runs efficiently year-round.
No Heat or Hot Water
One of the most frequent complaints is a lack of heat or hot water. This could be caused by a broken diaphragm, faulty thermostat, low boiler pressure, or airlock. A qualified boiler technician can quickly diagnose and fix.
Low Boiler Pressure
When your boiler’s pressure gauge drops below 1 bar, it can’t function properly. This might result from a water leak, recently bled radiators, or a failing pressure relief valve. Regular checks can prevent pressure-related shutdowns.
Strange Noises
Boilers that make banging, whistling, or gurgling sounds often suffer from limescale build-up or trapped air in the system. This issue, known as kettling, reduces efficiency and may damage the boiler over time if left unaddressed.
Pilot Light Failing
This could indicate a broken thermocouple, a draft, or a deposit build-up. This is a sign that the boiler isn’t igniting correctly and may require immediate attention to avoid a full system failure.
