Custom-built and modular masonry heaters

A self-builder's paradise! With Cœur de Foyer, you have access to all the components to create your custom-built masonry heater, whether as a participatory build or on your own. Our kits, refractory materials and fireboxes are designed to give you a personalised, high-performing and unique heater.

Stone or cast-iron fireboxes

Choose between cast iron for its immediate output or refractory stone for its thermal inertia. Each firebox is suited to your needs: the GOR44 for living spaces, or the GO18 to heat the whole house.

Heat-storing heaters suited to every project

Adjust the heat distribution to suit you: fast heat or slow heat, frequent or spaced-out loads. Our components are suitable for timber-frame, low-energy (BBC) or stone houses.

KMS heat-storage modules

Customise your flue gas circuit with the KMS system from ORTNER. Easy assembly with Orfix, angle pieces, T-pieces, with or without damper: total flexibility.
