Maintenance on Tankless shouldn't be too bad, buy a small sump pump, a 5 gallon pail, and a couple of short connector hoses, once a year, hook the sump pump up to the heater, and pump 4 gallons of white vinegar through the tankless heater for an hour. Certainly something that you can do yourself. If you have to bring in a plumber to look at the unit, make sure you call a plumber that is authorized for service by the tankless manufacturer.
We had a tankless heater in our old house both to save space, and we didn't have enough chimney size when we added the extra furnace for the basement suite. Chimney size forced us either to put in a high efficiency furnace, or a tankless water heater.
