The other thing you mentioned is that you are looking at a model that vents out through pvc pipe. Be aware, by using a power vent model like that is going to cause you even more of a delay before getting hot water. When you turn on a faucet, the flow sensor calls for hot water, but first, an exhaust blower has to turn on and ramp up, then a vacuum switch has to activate to show there's enough exhaust flow, then the burners light, then water can be heated.
What's the reason you are looking at a tankless? Is it because you want to take a 5 hour shower? Someone takes a lot of baths in a huge tub? Or is it because it will save money?
