Replacement Parts for HeatMaster Furnaces

From blowers to pumps, brackets to fan covers, Alternative Heating & Supplies stocks the parts & accessories you need to keep your HeatMaster wood boiler running efficiently and effectively. All of our replacement parts are compatible with HeatMaster models. Just locate your boiler model and select the part that it's designed to fit.

HeatMaster Wood Boiler Parts & Accessories

Blowers and Fans

Blowers and fans are components that regulate combustion and heat output and drive overall efficiency. They help supply the right amount of oxygen to the firebox, thereby allowing for complete combustion while controlling temperature.

Pumps and Circulation Components

Pumps and circulators act as the heart of the hydropic system. They ensure hot water is effectively moved from the boiler to the heat exchangers, radiators, or floor loops, resulting in even heat distribution throughout the property that the boiler is intended to heat.

Door Seals, Gaskets, and Insulation

These parts directly affect efficiency, wood consumption, and the boiler unit's overall lifespan. Seals and gaskets help create an airtight firebox, and insulation helps prevent heat loss.

Sensors, Controls, and Electrical Parts

These components improve wood-burning boiler efficiency, resulting in longer burn times and reliable, safe operation. These parts also help automate combustion, allowing the boiler to adjust the air-to-fuel ratio to precise, optimal levels.

Cleaners and Treatments

The use of cleaners and treatments is essential for maintaining the efficiency, safety, and longevity of your HeatMaster unit, and should be a part of your routine maintenance plan.

Signs Your HeatMaster Furnace May Need New Parts

How do you know if your HeatMaster furnace needs new parts? Here's a look at some signs:

  • Reduced heating performance
  • Increased fuel usage
  • Unusual noises coming from the unit
  • Airflow issues
  • Obvious wear and tear, or other signs of damage

How to Find the Right HeatMaster Part

Identify Your Furnace Model

When to Replace vs Repair

While some parts can be repaired, consider replacement parts when you notice rusting, warping, or cracks. Replacements should also be considered if there are notable performance issues.
