Message to send
Hello, I am looking for a true masonry heater / poele de masse in France, built around a Hoxter HE 37/50G insert. Can you quote a project in France including: - Hoxter HE 37/50G - full accumulation masonry / flue-gas channel system - transport, travel and lodging - estimated build time on site - photos of similar masonry heater / tiled stove projects - whether you can work with a French fumiste for DTU / insurance compliance I want a reliable, efficient radiant masonry heater, not a standard fireplace or BLOX unit. Thank you.
Now
- Email AR with the RFQ
- Ask for France travel confirmation
- Ask for 2-3 comparable builds
Next
- Get indicative price range
- Confirm French fumiste / DTU path
- Request Hoxter HE 37/50G quote
Before deposit
- EN 15544 style calculation
- Chimney / draft check
- Written scope and travel costs
Headless STEP + Rhino inspection

CAD readiness
- Ready
- Active modeler STEP package, 2D profile manifest, official Hoxter insert reference, dashboard GLB
- Simulation
- 111 named BREP bodies, locked insert reference, 2 swept smoke-path solids, 85 enclosed course/block masonry bodies, 12 cleanout-frame pieces
- Orientation
- CAD front/glass axis is +Y; dashboard preview rotates front/glass to the right
- Checks
- channel area 1.9 x Ø180 outlet, rectangular aspect 1:1, cleanouts at lower turns and upper collector
- STEP files
- active all, swept smoke paths, masonry courses, finish/connections/datums split for simulation setup
- Missing
- EN 15544 final sizing, EN 13384 chimney inputs, floor-load data, final mason connection choices
- Use now
- professional geometry handoff and simulation setup; not final execution CAD
Precision pass 2 dimensions
- Hoxter body
- 605 x 650 x 768 mm source dimensions, imported as Rhino OBJ reference
- Fire view
- HE 37/50 front glass reference, 370 x 500 mm
- Burn chamber
- 305 x 525 mm manufacturer chamber reference
- Connections
- Ø180 smoke outlet, Ø150 combustion air inlet
- Build layers
- split refractory walls, side storage masses, top collector, bench mass, outer reference envelope
- Smoke path
- orange generated void: outlet plenum, center riser, twin top headers, twin down channels, lower turns, rear collector, final Ø180 exit
- Open item
- smart CAD seed still needs EN 15544 / mason calculation before construction
Compliance process
- Site surveyMeasure chimney, floor structure, air supply, and combustible clearances after the object geometry is frozen.
- Appliance dataUse exact Hoxter HE 37/50G technical sheet, outlet, output, temperatures.
- Stove calculationDimension the one-off masonry heater with EN 15544 logic.
- Chimney calculationRun EN 13384-1 draft / temperature / condensation check.
- French executionConduit, tubage, raccordement and workmanship path under NF DTU 24.1.
- Sign-offMason/fumiste validates before build; this model is geometry, not certification.

Geometry before physics
Phase 01
Shapr3D source geometry
Build the real stove anatomy as separate bodies before any simulation.
- Model
- Existing wall, Hoxter insert, ring envelope, side masses, bench, collector, chimney outlet.
- Output
- Dimensioned blockout with named bodies and first mass envelope.
- Check
- Firebox, air inlet, outlet, channels, cleanouts, and mass layers remain readable in section.
- Risk
- Pretty outer masonry hiding impossible internal geometry.
