A Thermasse masonry heater is not bought: it is designed. Here is what we do for you, from the first sketch to the handover report — and in what order.
The path of a project
- 01
Study & design calculation
Plans, volumes, consumption: the sizing is calculated, not estimated.
→ your design calculation
- 02
3D design
The heater takes shape in your room, on screen, before the first brick.
→ 3D views of the project
- 03
Workshop preparation
The heater core is cut and dry-assembled in our workshop: the work on site at your home is shorter for it.
→ core ready to install
- 04
Construction & installation
Masonry, connection, commissioning — a single point of contact, qualified in masonry and flue work.
→ first fire
- 05
Handover & documents
Nothing leaves without its paperwork.
→ handover report, manual, heater data sheet, instructions

Key point — five stages, one point of contact, deliverables at each: design calculation, 3D, dry-assembled core, first fire, handover paperwork.
