Known for its exceptional performance, the Caddy Advanced is a furnace that’s innovative design (patent pending) is surpassed only by its simplicity of use.

The self-regulated combustion of the Caddy Advanced promises constant heat, while requiring minimal effort on your part; just fill the furnace, adjust the temperature and enjoy the heat for hours! The system automatically adjusts the air supply so that combustion is optimized and synchronized with the thermostatic demand.

  • At start-up, the furnace injects additional combustion air for easy and quick ignition.
  • As the furnace goes into heating mode, it automatically adjusts the combustion air supply and the operation of the convection blower. When your home’s desired temperature is reached (thermostat setting), the furnace goes into energy saving mode, automatically reducing the combustion air and speed of the convection blower.
  • At the end of the combustion cycle, if the furnace needs to go back to heating mode (thermostat setting), additional combustion air is injected again to activate the combustion of the embers thus providing a hotter burn on the end of the combustion cycle.

Use the Caddy Advanced with confidence thanks to its intuitive operation and illustrated quick user guide. Equipped with a glass door allowing you to easily monitor the state of combustion, the furnace optimizes its combustion cycle: you will spend much less time taking care of it vs a conventional furnace (loading wood, adjusting the air, etc.). This optimization also ensures you substantial savings in firewood as well as increased comfort thanks to the production of constant heat throughout the combustion cycle.

Among the most efficient furnaces in terms of energy distribution, the Caddy Advanced has one of the lowest minimum burn rates in the industry. This means a load of wood burns longer, and therefore reduces the frequency of wood loading. Emissions on this unit are amongst the cleanest of the few EPA 2020 certified furnaces, and yet the Caddy Advanced is among the most energy efficient on the market. In addition, the new ECM motor blower option consumes 40% less electricity (and much quieter) than a standard PSC motor blower.

The Caddy Advanced is equipped with pre-wired electrical components that allow for quick and hassle-free installation. For more flexibility, you can install the filter supports on either sides and on top of the blower box to adapt the layout of the ventilation ducts to your space. In addition, the add-on configuration allows you to install the Caddy Advanced with your existing electric, oil or gas central heating system to take advantage of an alternative energy source.

The Caddy Advanced includes a tool set and wall support, an ash lip, a thermostat, a moisture reader, a barometric damper and a fresh air intake adapter.

Alternate source of heat

Always have an alternate source of heat to ensure the comfort and safety of your family. The Caddy Advanced comes in two different configurations: wood-only and wood add-on furnace.

When installed as an add-on furnace, only a SERIES configuration is allowed only in Canada and the blower is not required.  |  Only PARALLEL configuration is allowed in the USA.



This furnace can be installed as a wood-only unit. Blower box with regular or ECM motor is required for this configuration.



If you’ve already got an oil, gas, or electric central heating system but want to add the flexibility of wood, the Caddy Advanced wood add-on furnace is for you. This unit, which installs on either side of your existing system, uses the same controls and fan as your existing furnace, giving you a fully compatible wood+oil, wood+gas, or wood+electric combo system.

Values are as measured per CSA B415.1-10, except for the recommended heating area, firebox volume, maximum burn time and maximum input capacity. Performances based on a fuel load prescribed by the standard at 10 lb/ft³ and with a moisture content between 18% and 28%.

Input value at 10 lb/ft³ fuel loading density and dry energy value of 8,600 BTU/lb.

Overall : Radiated and delivered heat together at 10 lb/ft³ fuel loading density over one total burn cycle.

Efficiency based on radiated and delivered heat when allowing cycling from high to low burn to simulate thermostat demand.

Delivered: Remotely provided to other rooms through ducting at 10 lb/ft³ fuel loading density over one total burn cycle.

Efficiency based on delivered heat when allowing cycling from high to low burn to simulate thermostat demand. LHV % is based on manufacturer’s estimation.

Optimum overall efficiency at a specific burn rate (LHV).

 The optimum heat transfer efficiency is for the low burn rate (using HHV) and represents the appliance’s ability to convert the energy contained in the wood logs into energy transferred to the room in the form of heat and does not take into account the chemical losses during combustion.

How do I reduce the amount of charcoal my heater produces?

Appliances that are EPA or CSAB415.1 certified tend to create larger coal beds due to their higher efficiency. This can be controlled by the way you burn your appliance. After an overnight burn, you may have a more significant coal bed. Simply rake the coal bed forward and add a smaller piece of wood on top. Burn the appliance on a higher setting (air control fully open). This will pull more primary air into the firebox and will increase the draft. The coal bed will burn down with the log. You may have to repeat this operation a couple of times before the coals are reduced. You are then ready to load your appliance with a larger fuel load.

Genuinely life-changing wood furnace!  100%

Gentlemen, now that we have properly cold weather, I can tell you that the Caddy Advanced is absolutely genius. We are getting 12-hour burns, using all of the heat from the coal bed, and keeping the house in the low 70s without big temperature swings. Since 9 a.m. this morning when I lit the fire, I've only opened it once to rake the coals over the ash grill.

12 hours of even heat on a bitterly cold, windy day and I only touched the furnace once . . . For people who heat with wood, this is genuinely life-changing!
