I’m doing several rehabs on older, smaller homes in our dense urban park. Most of the homes are 2 bed 1 bath homes and we need to replace several water heaters. I was thinking with only 1 bathroom a tankless water heater might be a viable solution, but after some research it looks a little borderline on whether a $200-$300 small tankless water heater off ebay would be sufficient for a one bath house. Has anyone tried installing tankless water heaters on their small homes to save some money up front and increase the home’s energy efficiency? The homes are in Ohio, so the winter water temperatures start out pretty cold before they reach the water heater.
Also for buying traditional water heaters does anyone have any recommendations on how to save money on that end, or do you just go into home depot and pay retail for it?
