Introduction to Connecticut Boiler Guide
Boilers are a great choice for Connecticut homes as they provide continuous heat and hot water during the cold months. If you're replacing an old system or switching from another heating method, knowing your options can help you make the best choice for your house. Our Connecticut home boiler guide will tell you everything you need to know about residential boiler installation and replacement.

Understanding Residential Boilers
A boiler is a water-based heating device that distributes heat throughout your home. Unlike forced-air systems, which rely on ducts and vents, boilers heat through radiators or radiant floor heating. Boilers are often chosen by homeowners for their efficiency, durability, and ability to provide consistent and comfortable heating.
Types of Boilers
There are several different options that homeowners can choose from when it comes to home boilers. They each come with their own benefits:
Gas Boilers:
Popular in areas with natural gas service, they offer high efficiency and lower fuel costs.
Oil Boilers:
Common for homes with no natural gas service, they provide strong heating, but require regular fuel deliveries.
Electric Boilers:
Great option for smaller homes or condos, or areas with no natural gas or oil services. Operating costs may be higher than the above options.
Condensing Boilers:
High-efficiency systems that capture heat from exhaust gasses, reducing energy waste and lowering your utility bills.
Combi Boilers:
A great option for space saving, they provide both heat and hot water without needing a separate water heater.



Signs You Need a Boiler Replacement
Replacing a boiler is a pretty big investment, but switching to a newer one can improve efficiency, lower energy bills, and increase home comfort. Some important indicators that it may be time for a replacement include:
Age:
Most standard boilers last 15-30 years, consider upgrading if yours is approaching or in this range.
Rising Energy Bills:
Older boilers can lose their efficiency over time, which can increase your heating costs.
Frequent Repairs:
If your boiler keeps breaking down and needing repairs, a replacement may be a more economical choice.
Inconsistent Heating:
Uneven heating and cold spots throughout your home may indicate a failing boiler.
Strange Noises:
Banging, whistling, or clanking sounds likely mean that there is an internal issue with your boiler that needs to be checked out.
