usually only one person household, company on occasions. have 2 full baths, washing machine and dishwasher, but small usage on dishwasher. what are benefits of tankless? are they more energy/cost efficient? problems with installation or maintenance? mine would be gas heater, as that is what my furnace is. any references on brands or companies that install (Garner NC area)?
No, a gas setup would be more like getting a replacement regular water heater. The only difference would be that the exhaust and air intake setup would need to be fully re-piped or ducted. Otherwise, a tankless would work great for you and would likely drop your gas bill by 20% or more. Not an immediate payback, of course, but still pretty quick. There really isn't a downside for a gas setup, if you choose a robust model to start with.
