Evidence before recommendation

How Sauna Selector verifies sizing & compatibility

The site is designed around documented specifications rather than visual similarity, retailer copy or a single universal rule.

Source hierarchy

  1. Current manufacturer product page.
  2. Current manufacturer installation or owner manual.
  3. Manufacturer sizing calculator or compatibility chart.
  4. Manufacturer technical data sheet or support documentation.
  5. Authorized dealer data when manufacturer information is incomplete.
  6. Other authoritative technical sources.

Match-status vocabulary

VERIFIED — MANUFACTURER LISTEDThe manufacturer explicitly lists the pairing, model, range or fit.
VERIFIED — DOCUMENTED RANGE MATCHThe calculated requirement falls within a published manufacturer range.
VERIFIED — DOCUMENTED INTERFACE MATCHDocumented electrical/control/interface requirements align.
CONDITIONALThe technical relationship appears plausible, but an installation or code requirement still needs verification.
NOT COMPATIBLEDocumented requirements conflict.
UNKNOWN / NOT ENOUGH DOCUMENTATIONThe evidence is not strong enough to justify a confident result.

Heater sizing remains manufacturer-specific

Interior room volume is a useful starting point, but it is not the entire sizing problem. Glass, masonry, logs, insulation and other uninsulated surfaces can change the effective heating requirement, and manufacturers do not always express those adjustments in exactly the same way.

The heater-sizing methodology preserves manufacturer-specific calculations where current documentation supports them instead of inventing one universal equation and presenting it as authoritative.

Commercial links are a separate layer

A merchant relationship cannot upgrade a conditional result to verified, change a heater-size result, or cause one sauna to outrank another. The evidence and user constraints come first.

Frequently asked questions

What sources will Sauna Selector prioritize?

Current manufacturer product pages, installation manuals, sizing calculators, compatibility charts and technical data are preferred. Retailer summaries and forum discussions do not override current manufacturer documentation.

What does conditional mean?

Conditional means the documented specifications appear compatible, but an installation detail such as electrical service, clearances, control equipment, climate, mounting or local code still needs verification.

Will the site guess when documentation is incomplete?

No. When the available evidence does not support a confident conclusion, the result should be unknown or conditional and explain what still needs to be checked.

Are forum posts used as technical evidence?

Forum posts can reveal buyer pain points and failure modes, but they are not treated as authoritative evidence for specifications or compatibility.
