Plumbing Radiant Tubing Spacing Calculator
Read actual matched tube spacing/floor-output trials, select widest compatible tested candidate; no invented floor-construction heat-output model or installation/comfort guarantee.
Description
Radiant tube-spacing trials compare measured heat output under matched floor conditions.
Radiant tube-spacing trials compare measured heat output under matched floor conditions. The widest adequate tested spacing can differ from a theoretical design.1
The returned values include Widest observed compatible tube spacing mm, Caller output reachable in tested spacings. The How section below explains the calculation, input rules and interpretation.
When to use Plumbing Radiant Tubing Spacing Calculator
Use Plumbing Radiant Tubing Spacing Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No interpolation, floor-construction model or comfort guarantee is supplied.
Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
How to use Plumbing Radiant Tubing Spacing Calculator and understand its results
- Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
- Enter callerTestedTubeSpacingMm, callerMatchedFloorOutputWattsM2, callerRequiredFloorOutputWattsM2 using the field table and calculation rules, then run the tool.
- Read widestObservedCompatibleTubeSpacingMm, callerOutputReachableInTestedSpacings. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| callerTestedTubeSpacingMm | Caller tested tube spacing mm | list of number | Required |
| callerMatchedFloorOutputWattsM2 | Caller matched floor output watts m2 | list of number | Required |
| callerRequiredFloorOutputWattsM2 | Caller required floor output watts m2 | number | Required |
Enter a nonempty positive strictly increasing spacing list, aligned nonnegative matched outputs and nonnegative required output. Return the widest adequate spacing and true; if none qualifies, return −1 and false. Output values need not be monotone.
choose largest tested spacing whose output≥required Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| widestObservedCompatibleTubeSpacingMm | Widest observed compatible tube spacing mm | number |
| callerOutputReachableInTestedSpacings | Caller output reachable in tested spacings | boolean |

}Limitations and assumptions
No interpolation, floor-construction model or comfort guarantee is supplied.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
Alternative or Complementary methods
Use Plumbing Radiant Floor Heat Output Calculator: A linear floor-emission model uses surface-to-room temperature difference, area and an effective emission coefficient. Cooling remains negative. For a complementary task, use Plumbing Radiant Manifold Flow Calculator: A manifold closure audit distinguishes known port flows from missing evidence. Header-minus-known flow remains signed.
