Looking to upgrade to a Tiffin Bus all electric and wondering the pros and cons also heated floors pros and cons. I live in North Idaho and store my RV out doors and how the heated floors are in cold
No real cons, except in an all-electric coach you must be looking at Aqua-Hot heating. There are a few more moving parts (and thus more to break) than a Suburban propane furnace. But you also get hot water ( and engine pre-heat if so equipped ), so the "too many parts" argument may be a wash. Aqua-Hot requires yearly cleaning and tuning of the burner.
The heating coils and boiler should be filled with boiler anti-freeze, typically good down to -100° F.
