Research support, not installation approval.
Use the equipment information on this site as an aid to planning and procurement, then verify your final decisions with the parties responsible for the installation.
Information accuracy
We make a good-faith effort to cite and update facts, but models, specifications, pricing and availability can change. Check the latest manufacturer documentation and merchant quote before purchasing.
Compatibility limits
Our checks do not replace electrical, mechanical, fire-code or health-code review. A licensed professional and your local authority must determine whether an installation is permissible.
External transactions
We do not sell, finance, install or service equipment through this site. Transactions and quotes on linked websites are between you and the external provider.
