Q about tankless water heaters
While a tankless hot water heater is not necessarily a renewable energy source but itself, I thought someone here might have some experience with these.
We have a 1200 sq ft home, with 1 shower/clawfoot tub, 2 lavoratory sinks, 1 kitchen sink, 1 dishwasher, and 1 front-loading washing machine. We are interested in replacing our current tank water heater with an electric tankless, for energy savings and to reclaim closet space.
So my question is, what are the advantages and disadvantages of whole house heaters versus point-of-use? We are renovating and considering installing point-of-use heaters on some of the fixtures as we replace them, and then eventually installing a whole house tank if needed for things like the dishwasher where a point-of-use heater might not be robust enough. For example, in takes several minutes to get hot water to our bathroom sink currently. This is probably not an issue with the water heater but the distance from the tank to the sink, so we figured POU would be better for that situation (though we realize it would probably cost more for several POU versus one whole house). Also, since we are having a wicked drought here, I HATE running the water for several minutes just to get the hot water.
Does anyone have either of these and what are the pros and cons between the two, given our house and fixtures?
