A high-performance masonry heater core system designed to burn wood efficiently, store heat, and release it slowly for long-lasting comfort.
Designed from decades of masonry heater experience for clean combustion, lasting radiant heat, and timeless masonry craftsmanship.
Most people have never heard of a masonry heater—but it’s one of the most efficient and comfortable ways to heat a home with wood.
HeatKit is built to make this proven heating method more accessible, reliable, and consistent through a carefully engineered core system.
A masonry heater allows you to heat your home with wood in a unique way.
Its main distinction is the ability to store a large amount of heat.
This means that you can rapidly burn a large charge of wood without overheating your house. The heat is stored in the masonry thermal mass, and then slowly radiates into your house for the next 18
to 24 hours.
HeatKit works on a proven principle—burn hot, store heat, and release it slowly over time.
Instead of constant burning, the system captures energy from a single, efficient fire and delivers steady warmth throughout the day.
A full load of wood is burned quickly at a high temperature. This allows the system to operate in its most efficient and clean-burning state, reducing smoke and maximizing heat output.
The heat generated during the burn is absorbed into the masonry core. This dense thermal mass stores a large amount of energy, even after the fire has ended.
Once stored, the heat is gradually released into your home over the next 18 to 24 hours. The result is consistent, even warmth without constant refueling or temperature fluctuations.
Because the system burns wood at optimal temperatures, it produces fewer emissions and makes better use of fuel. Even smaller fires remain clean and effective.
HeatKit is a proven masonry heater core system designed to simplify construction while maintaining high performance. Instead of building from scratch, HeatKit provides a tested foundation that ensures consistent results.
Benefits:
A masonry heater works differently from traditional wood stoves.
Instead of burning wood slowly throughout the day, it burns a full load of wood quickly at high temperature.
The heat is then stored in the masonry structure and released gradually over the next 18 to 24 hours.
This approach creates a clean, efficient burn while providing steady, even warmth.
Proper construction is essential for safety, efficiency, and long-term durability. HeatKit systems are best installed by experienced masonry professionals or skilled builders familiar with masonry heater construction.
If you’re interested in building a masonry heater, the next step is working with an experienced professional installer. HeatKit offers installation services in select regions, and masonry heater builders can also be found through the Masonry Heater Association.
