Comfort and Peace of Mind

Heatmasterss offers time saving and convenient features to make running your furnace simple. Some of our most popular features are:

  • Shaker grates and removable ash pan make cleaning a breeze. Just shake the grates and pull out the ash pan to remove ash.
  • The forced air fan pushes air through the grates at the bottom of the firebox, which helps provide fast heat recovery.
  • The hinged rear door gives easy access to the rear of the furnace for simple maintenance
  • Multi-fuel capability gives you flexibility in what you choose to burn in your furnace

High Efficiency 

The triple heat exchange pass flue dumps this heat into the water jacket before the exhaust exits the furnace. This reduces fuel consumption by 20-30% and eliminates spark or flame from the chimney. This baffle system also minimizes ash buildup, saving you time and effort.

409 Stainless Steel - The Best Material

We combine the best materials with expert engineering to create the most rugged, longest lasting furnaces available. Titanium enhanced, corrosion resistant 409 Stainless Steel is the only product that can provide the right blend of longevity, cost-effectiveness and other critical traits that meet the HeatMasterSS standard of excellence.

409 Stainless Steel is the best choice for your furnace because:

  • It resists corrosion. 409 Stainless steel is coated with a chromium film so it will not corrode from:
    • wet ashes or creosote in your firebox
    • sweating on your water jacket
    • corrosive elements in your water
  • It can withstand higher continuous temperatures. 
  • It transfers more heat. Heat gets to your water at a higher rate which will save you on fuel.
  • It has a low Thermal Expansion Rate. It won’t crack and warp in a high heat environment.

HeatMasterSS furnaces are built to the very highest standards with ISO 9001 Certified manufacturing processes.
