Our 40 gallon propane water heater is due to be replaced and we’re looking at Tankless system to be more efficient and also save some space in our cabin’s cramped utility room. We drain our water lines every fall and do NOT have a water softner installed on our well. The cabin only has 1 bathroom so it really only needs hot water for evening showers and the occasional rinsing of dishes in the sink (no dishwasher)
My questions are as follows:
1) Will the lack of a water softner hurt a tankless unit? will corrosion be an issue?
2) Are tankless systems ok to be drained completely in the fall and then primed back up in the spring?
3) Are tankless systems as reliable as standby tank systems?
4) I believe our current tank system uses a power vent to blow exhaust out, can tankless systems do the same?
