Common Mistakes to Avoid When Installing a Boiler
                     COMMON 
MISTAKES TO 
AVOID WHEN 
INSTALLING A 
BOILER
FAILING TO OBTAIN NECESSARY 
PERMITS
One of the first steps many homeowners overlook is checking for 
necessary permits. Most local building codes require permits for boiler 
installation to ensure safety and compliance with regulations. Failing to 
obtain the required permits could lead to fines and complications if you 
need to sell your home or if an inspector evaluates your installation.
IGNORING MANUFACTURER 
INSTRUCTIONS
Every boiler comes with a manufacturer’s manual, which includes crucial 
details and specifications integral to a successful installation. Ignoring 
these instructions can lead to improper installation and potentially void 
any warranties. Always read and follow the manufacturer’s guidelines to 
ensure the boiler functions correctly and safely.
INADEQUATE SIZING OF THE 
BOILER
Selecting the right size boiler for your home is essential for efficiency. A 
unit that is too small will struggle to heat your home, while one that is 
too large will cycle on and off too frequently, wasting energy and 
increasing wear and tear. Always consult with a professional to 
determine the appropriate size based on your home’s specific heating 
requirements.
POOR LOCATION 
CHOICE
The placement of the boiler is crucial for optimal performance and safety. 
Installing the unit too close to walls or clutter can impede ventilation and 
increase the risk of fire hazards. It is essential to provide adequate space 
around the boiler for maintenance and repairs and to ensure that it is 
placed in a well-ventilated area.
SKIPPING THE PRESSURE 
TEST
After installation, performing a pressure test is vital to ensure there are 
no leaks in the system. Skipping this step can result in water damage, 
decreased efficiency, and hazardous conditions. Always conduct a 
thorough pressure test and inspect all connections for potential leaks 
before putting your boiler into operation.
DIY 
INSTALLATION
While it may seem cost-effective to install the boiler yourself, this is a 
risky endeavor. Proper boiler installation requires specialized knowledge 
and skills that many homeowners lack. Each mistake during installation 
can lead to safety hazards or operational inefficiencies. Hiring a 
professional ensures that the job is done correctly and according to all 
regulations.
