Find top rated boiler installers in your area

Boilers generate heat by warming water or producing steam that flows through radiators, baseboard heaters, or underfloor systems to warm your home. In contrast, furnaces produce heated air distributed through a duct system across the dwelling. This distinct heating method determines system design, installation requirements, and energy distribution efficiency, ultimately impacting overall performance.

While both a water heater and a boiler heat water, they have different operations and functions. A boiler heats your home by pushing water or steam through the system. A water heater only heats potable water for faucets, showers, and appliances. Certain boilers, such as combi-boilers, can perform both functions.

Plumbers can install boilers under local codes. However, the process required the certified expertise of HVAC technicians to ensure safety and regulatory compliance. For gas boilers, a specialized gas plumber handles the fuel line connections to secure the system. This professional approach guarantees optimal performance and long-lasting, building code-compliant installations.

Boilers can last anywhere from 15 to 20 years, at which point they require replacement. If your boiler is frequently breaking down or losing performance, consider replacing it. Faulty boilers can lose efficiency and drive up your utility bills. As they degrade, they become less reliable. Some breakdowns, such as broken seals or valves, may result in extensive water damage or other hazards.

Replacing a boiler takes between four hours and three days. The installation duration depends on factors such as the need for additional gas line installation and whether the installation involves switching boiler systems. Replacing a boiler in the same system may be completed in as little as four to six hours, whereas converting systems extend the process.

Relocating a boiler to a new area within your home is not recommended. Boilers are installed in specific locations adjacent to essential pipes and radiators. Moving a boiler requires extensive reconfiguration of the delivery system and incurs substantially higher costs, making the process complex and expensive. This solution is far less practical than replacing the boiler in its original location.
