Install Boiler questions, answered by experts

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.
