This model is not offered in LP gas and there is no conversion kit available.
Yes, this unit can be set up for radiant heat only.
It is not recommended to combine your heating and plumbing combined on this unit. It would be best to have a separate heater or boiler for the radiant system, and a heater for the plumbing. An alternative would be to have a heat exchanger placed in the system separating the plumbing from the heating.
This water heater produces 121 gallons an hour, so it should be sufficient. There is no zoning guide available. There is only an installation manual: http://s3.pexsupply.com/manuals/1277918330238/33851_PROD_FILE.pdf
Paul, please see my review. Based on one month usage my answer to your question is absolutely YES.
The heater is set at the factory to operate at altitudes from sea level to 3,500 ft. (1,067m). Accessory kits are available to allow the heater to operate at altitudes higher than 3,500 ft. (1,067m).
The manufacturer recommends using a potable water source, where the water is filtered and strained as much as possible. It is hard to make a determination of how long this unit will last without knowing the iron level of your water, however, the manufacturer recommends getting the water as neutral as possible.
