New Boiler Owner Guide
Just had a boiler installed, or moved into a home with one? Here is what every owner should know to run it safely and keep it healthy.
Whether you just had a new boiler installed or inherited one with a new home, a little knowledge goes a long way. You do not need to be a technician — you need to know the basics that keep the system safe, spot trouble early, and protect your investment. This is the orientation every owner should have.
Know your system
- What type you have — combi, system or conventional — and its brand and model.
- Where the boiler power switch and gas isolation valve are.
- Where the pressure gauge is and what normal pressure looks like.
- How to read and reset a fault code (once).
Healthy operating habits
- Keep the area around the boiler and the outside flue terminal clear.
- Watch for new noises, leaks, or pressure that will not hold.
- Test your carbon monoxide alarms and keep them current.
- Resist the urge to repeatedly reset a recurring lockout.
Protect your investment
Book annual servicing, keep your installation and service records together, register the warranty, and build a relationship with a licensed local technician. Knowing who to call before an emergency turns a winter breakdown from a crisis into a phone call.
Key takeaways
- Learn your boiler type, shut-offs, normal pressure and how to read a code.
- Watch for new noises, leaks and pressure loss; keep CO alarms current.
- Service annually, keep records, and know who to call before you need them.
Frequently asked questions
What should I do first with a new boiler?
Have the installer walk you through the controls, show you the power and gas shut-offs and the pressure gauge, register the warranty, and book your first annual service. Keep all the paperwork together.
I moved into a home with an old boiler — what now?
Book a service so a technician can assess its condition and safety, confirm it has been maintained, and flag anything that needs attention. It is the best way to start with confidence and a baseline record.
