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

  1. Email AR with the RFQ
  2. Ask for France travel confirmation
  3. Ask for 2-3 comparable builds

Next

  1. Get indicative price range
  2. Confirm French fumiste / DTU path
  3. Request Hoxter HE 37/50G quote

Before deposit

  1. EN 15544 style calculation
  2. Chimney / draft check
  3. Written scope and travel costs

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

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

Compliance process

  1. Site surveyMeasure chimney, floor structure, air supply, and combustible clearances after the object geometry is frozen.
  2. Appliance dataUse exact Hoxter HE 37/50G technical sheet, outlet, output, temperatures.
  3. Stove calculationDimension the one-off masonry heater with EN 15544 logic.
  4. Chimney calculationRun EN 13384-1 draft / temperature / condensation check.
  5. French executionConduit, tubage, raccordement and workmanship path under NF DTU 24.1.
  6. Sign-offMason/fumiste validates before build; this model is geometry, not certification.

Modelling pipeline

Geometry before physics

Pick a step

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.
