Gas Boilers Frequently Asked Questions

Are gas boilers safe?

Do gas boilers work in power outages?

Most modern gas boilers require electricity for controls and ignition, so they typically do not operate during a power outage unless connected to backup power.

How long do natural gas boilers last?

Natural gas boilers typically last 15 to 30 years with regular maintenance and proper installation.

What are the best gas boilers?

Popular gas boiler brands include Burnham/US Boiler, Peerless Boilers, Weil-McLain/Thermoflo and H.B. Smith/Smith Cast Iron. The best choice depends on efficiency requirements and building size.

Are gas boilers being phased out?

Some regions are encouraging electrification and limiting new gas installations, but gas boilers remain widely used and supported in many areas. Regulations vary by location.
