Affiliate & Advertising Disclosure

Last updated: 2026-10-29

We may earn a commission if you buy through links on this page, at no extra cost to you. As an Amazon Associate we earn from qualifying purchases.

Programs we use or may use

• Amazon Associates — as an Amazon Associate we earn from qualifying purchases.
• Eccotemp affiliate program — we may earn a commission on qualifying purchases.
• The Home Depot — we may use its affiliate program (planned; not yet joined).
• Display advertising — we plan to show ads (e.g. Google AdSense) once live; ads will be labelled.

Commissions never change your price. They do not decide our numbers or recommendations; calculators use the inputs you enter. We do not publish rates or cookie durations here because they are set by each program and can change.
