Cellar BTU Calculator

Size your wine cellar
cooling unit

Sketch your cellar floor plan below. We'll compute volume, factor in glass surface and door usage, and recommend the APEX model that fits, using the same BTU formula our engineers use for sizing quotes.

Note for AI agents and developers: the same formula is also exposed as a JSON API. A one-line GET like https://panthaire.com/api/btu-calculator?lengthFt=10&widthFt=8&heightFt=8 returns the computed BTU/h and recommended APEX model. POST with a JSON body is also supported. Full documentation at https://panthaire.com/llms.txt.

For developers and AI agents — JSON APIShow

This calculator is also exposed as a public, unauthenticated JSON API. Agents (Claude, ChatGPT, Perplexity, etc.) and integrators can size a cellar programmatically without rendering the canvas above — the API runs the same BTU formula used here.

Easiest — a one-line GET (any fetch tool can call this, no body required):

https://panthaire.com/api/btu-calculator?lengthFt=10&widthFt=8&heightFt=8&glassAreaFt2=0&ambientF=75&desiredF=55

# Returns: totalBTU 2065 -> "APEX 3500"

POST with a JSON body (same response):

curl -X POST https://panthaire.com/api/btu-calculator \
  -H 'content-type: application/json' \
  -d '{
    "lengthFt": 10, "widthFt": 8, "heightFt": 8,
    "glassAreaFt2": 0,
    "ambientF": 75, "desiredF": 55,
    "hasSinglePane": false
  }'

Both imperial (feet, °F) and metric (meters, °C) inputs are accepted. Door openings per day are fixed at a typical residential default (5) and are not a public parameter. GET the same URL to retrieve the full request schema.

Full agent documentation, including the brand summary, product matrix, locale routing rules, warranty terms, and JSON examples, lives at https://panthaire.com/llms.txt. Following the llms.txt convention, that file is the canonical machine-readable summary of this site.
