    Does the building already have a boiler?

    If not, the installation savings from electric cable will probably exceed the energy cost difference over its lifetime.

    hydronic with a small electric boiler or 6 gallon tank wh. Then you have options for a heat source

    Note that there is zero savings on electricity cost vs electric cable in-floor. The installation is going to be substantially more expensive, if you ever lose power you run the risk of it freezing. I'll grant that it is more flexible in the future, you have to balance the pros and cons.

    I have heard of many electric cable or mat system failing. Then your done. They finally started sending “loud mouths” with the Watts Radiant electric systems to alert you if a damaged cable durning tile application.

    If the radiant tube in your bathroom freezes you probably have bigger problems to worry about😮
