What we earn today: nothing

There are no affiliate links on this site, no advertising and no sponsored placements. Every outbound link goes where it goes because it is the source of a figure or the place the product is sold, and we are paid nothing if you follow it.

We are saying so plainly because the opposite is so common. A boilerplate commission notice on a site that earns no commission is not a harmless precaution — it is a false statement about who is paying us, and we would rather not make one. When affiliate links do appear, this page and the footer will change to say so, and they will change automatically, because the wording is driven by the same configuration that switches the links on.

What it will never buy

Nothing about a commercial arrangement changes a number on this site. Melt capability and running costs are computed at build time from manufacturer specifications and public climate and energy data; there is no field in our data for who pays us, because the calculations never consult one. Where the honest answer is that a mat will not keep up, or that the money is better spent on an embedded system we earn nothing from, the page says so.

The clearest example is on the site already. Our own figures put portable mats at roughly three times the cost per square foot of an embedded system, and the mats are the layer we would earn from. The calculators say so anyway.

AI assistance

Pages here are drafted with AI assistance and reviewed by a person before publication. We think readers are entitled to know that, so we say it in the footer of every page rather than in a policy nobody opens.

What we are not paid for

• No manufacturer has paid for coverage, placement or a rating on this site.
• We accept no free product, because we do not test product.
• No sponsored posts, and no links sold to third parties.
