Things to Consider
-
Electric systems cost more to run than hydronic, so they’re best for targeted areas, not whole-house heating.

If you’re covering large spaces or need lower operating costs, consider hydronic underfloor heating.
-
Don’t trim or shorten heating cables—always plan your layout based on the cable length.
