Better spring for something more around $1000 or so. Also keep in mind those need yearly maintenance.
Usually involves taking it offline and pumping vinegar through it to clean out calcium deposits in the heat exchanger. Get the “optional” hose connector kit for the maintenance.

Will it work??
There is a reason the radiant heating boilers are more expensive. With a once through On-Demand water heater, the incoming water temperature is pretty low and constant. With a closed loop system, you have variable pressures and temperatures to deal with. Also, with a closed loop, you treat the water in the loops so it will not corrode or scale.

The cynic in me always asks why so cheap. What’s wrong with it? Does it require a special venting material? Is it certified for use as a space heating appliance? Is it close to matching the BTU load from the floor? God forbid you want to get hot water from it as well.
Can a tankless water heater be used to heat a floor? Sometimes maybe.

Bad experiences come from poor decisions. So do good stories.
